KubeSphere DevOps Pipeline Management
Overview
Pipelines in KubeSphere DevOps are Kubernetes custom resources that integrate with Jenkins. KubeSphere uses a cloud-native, object-reconcile approach where Kubernetes resources are the source of truth.
When to Use
Creating or updating CI/CD pipelines
Triggering pipeline runs
Monitoring pipeline execution
Retrieving pipeline logs and artifacts

Troubleshooting failed pipeline runs
Architecture Mapping KubeSphere DevOps maps Kubernetes resources to Jenkins objects:
KubeSphere Resource K8s Resource Jenkins Resource DevOpsProject DevOpsProject CR + Namespace Folder Pipeline Pipeline CR WorkflowJob PipelineRun PipelineRun CR Build Run Workspace Workspace CR (authorization context)
KubeSphere Kubernetes Jenkins
─────────────────────────────────────────────────────────────
Workspace demo
└── DevOpsProject → demo-project NS → Folder demo-project
└── Pipeline → Pipeline CR → WorkflowJob
└── Run → PipelineRun CR → Build #1
Triggering Pipeline Runs (Recommended: Object-Reconcile)
CRITICAL: ALWAYS Check for Parameters First!
Before triggering ANY pipeline (regular or multi-branch), you MUST check if the pipeline has parameters defined.
Triggering a pipeline without required parameters will cause the build to fail or use incorrect defaults.
For Multi-Branch Pipelines: Query /branches/{branch} endpoint to get .parameters array
For Regular Pipelines: Query the Pipeline CR and check .spec.pipeline.jenkinsfile for parameters {} directive
Preferred Approach: Create a PipelineRun custom resource. KubeSphere watches for these resources and triggers the corresponding Jenkins build.
Create a PipelineRun apiVersion: devops.kubesphere.io/v1alpha3
kind: PipelineRun
metadata:
name: my-pipeline-run-001
namespace: demo-project
spec:
pipelineRef:
name: my-pipeline
parameters:
- name: BRANCH
value: "main"
kubectl apply -f pipelinerun.yaml
Check PipelineRun Status # List all runs
kubectl get pipelineruns -n demo-project
# Get specific run status
kubectl get pipelinerun my-pipeline-run-001 -n demo-project -o yaml
# Watch run progress
kubectl get pipelineruns -n demo-project -w
PipelineRun Status Fields Field Description status.phaseCurrent state (Pending, Running, Succeeded, Failed, Unknown) status.conditionsDetailed conditions (Succeeded, Ready) status.completionTimeWhen run finished status.startTimeWhen run started
Delete a PipelineRun kubectl delete pipelinerun my-pipeline-run-001 -n demo-project
Working Pipeline Example Here's a complete, working pipeline that builds a Go application:
apiVersion: devops.kubesphere.io/v1alpha3
kind: Pipeline
metadata:
name: go-demo-pipeline
namespace: demo-project
spec:
type: pipeline
pipeline:
name: go-demo-pipeline
description: "Build and test Go application"
jenkinsfile: |
pipeline {
agent any
stages {
stage('Build, Test and Archive') {
agent {
kubernetes {
yaml '''
apiVersion: v1
kind: Pod
spec:
containers:
- name: golang
image: golang:1.21
command: ["sleep"]
args: ["99d"]
'''
}
}
steps {
container('golang') {
sh '''
export GO111MODULE=on
git clone https://github.com/kubesphere-sigs/demo-go-http.git .
go mod download
go test ./... -v
go build -o service main.go
'''
}
archiveArtifacts artifacts: 'service', followSymlinks: false
}
}
}
}
Uses agent { kubernetes { yaml ... } } to define a custom pod with Go container
The archiveArtifacts step must be in the same stage as the build (same workspace)
Container name in container('golang') must match the container name in the YAML
Pipeline Resource apiVersion: devops.kubesphere.io/v1alpha3
kind: Pipeline
metadata:
name: my-pipeline
namespace: demo-project
spec:
type: pipeline
pipeline:
name: my-pipeline
description: "Build and deploy app"
jenkinsfile: |-
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'make build'
}
}
}
}
Tenant-Created Resources: Creator Annotation When creating pipelines as a tenant (not cluster-admin), you MUST include the kubesphere.io/creator annotation to properly track ownership:
apiVersion: devops.kubesphere.io/v1alpha3
kind: Pipeline
metadata:
name: my-pipeline
namespace: demo-project
annotations:
kubesphere.io/creator: "stone-ns-admin" # Required for tenant-created resources
spec:
type: pipeline
pipeline:
name: my-pipeline
description: "Pipeline created by tenant"
jenkinsfile: |-
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'echo Building...'
}
}
}
}
KubeSphere uses this annotation for ownership tracking
UI displays creator information
Required for proper RBAC enforcement
CRITICAL: Always set this annotation when creating ANY pipeline via API (both regular and multi-branch) Example API call with creator annotation for regular pipeline:
curl -s -X POST "${KUBESPHERE_API}/kapis/devops.kubesphere.io/v1alpha3/namespaces/demo-project/pipelines" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
"apiVersion": "devops.kubesphere.io/v1alpha3",
"kind": "Pipeline",
"metadata": {
"name": "my-pipeline",
"namespace": "demo-project",
"annotations": {
"kubesphere.io/creator": "'${USERNAME}'"
}
},
"spec": {
"type": "pipeline",
"pipeline": {
"name": "my-pipeline",
"description": "Tenant-created pipeline",
"jenkinsfile": "pipeline { agent any; stages { stage(\"Build\") { steps { sh \"echo hello\" } } } }"
}
}
}'
Multi-Branch Pipeline Multi-branch pipelines automatically discover branches from SCM and create jobs for each branch. The Jenkinsfile is loaded from the repository.
⚠️ CRITICAL: Always Check Repository Type First
Before creating a multi-branch pipeline, you MUST ask the user:
"Is this a private repository?"
If YES (Private Repo):
Ask if they want to use an existing credential or create a new one
Create a DevOps credential (basic-auth type with GitHub PAT) if needed
Reference the credential in git_source.credential_id
(Optional) Create a GitRepository CR for additional metadata
If NO (Public Repo):
Set credential_id: "" (empty string)
Never assume repository type - always confirm with the user first.
Create Multi-Branch Pipeline Step 1: Check Repository Type
Ask user: "Is the repository private?"
If yes, proceed with credential creation
Step 2: Create Credential (For Private Repos Only)
# Create GitHub credential
export GITHUB_PAT="ghp_xxxxxxxxxxxxxxxxxxxx"
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/credentials" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
"apiVersion": "v1",
"kind": "Secret",
"metadata": {
"name": "github-token",
"namespace": "'${DEVOPS_PROJECT}'",
"annotations": {
"kubesphere.io/creator": "'${USERNAME}'",
"credential.devops.kubesphere.io/type": "basic-auth"
}
},
"stringData": {
"username": "git",
"password": "'${GITHUB_PAT}'"
},
"type": "credential.devops.kubesphere.io/basic-auth"
}'
Step 3a: For Public Repository:
apiVersion: devops.kubesphere.io/v1alpha3
kind: Pipeline
metadata:
name: demo-jenkinsfiles-go
namespace: demo-project
annotations:
kubesphere.io/creator: "stone-ns-admin" # Required for tenant-created resources
spec:
type: multi-branch-pipeline
multi_branch_pipeline:
name: demo-jenkinsfiles-go
description: "Multi-branch Go pipeline"
source_type: git
git_source:
url: https://github.com/kubesphere/demo-jenkinsfiles
credential_id: "" # Empty for public repos
discover_branches: true
discover_tags: false
script_path: go/Jenkinsfile # Path to Jenkinsfile in repo
Step 3b: For Private Repository (with credential):
apiVersion: devops.kubesphere.io/v1alpha3
kind: Pipeline
metadata:
name: private-repo-pipeline
namespace: demo-project
annotations:
kubesphere.io/creator: "stone-ns-admin"
spec:
type: multi-branch-pipeline
multi_branch_pipeline:
name: private-repo-pipeline
description: "Pipeline for private repository"
source_type: git
git_source:
url: https://github.com/org/private-repo.git
credential_id: "github-token" # Reference to DevOps credential
discover_branches: true
discover_tags: false
script_path: Jenkinsfile
Complete Flow for Private Repo:
Ask user if repository is private (ALWAYS do this first)Create credential (basic-auth type with GitHub PAT)(Optional) Create GitRepository CR (with provider and secret fields)Create multi-branch pipeline referencing the credential in git_source.credential_id Important: Never use GITHUB_ env vars directly in the pipeline spec. Always create proper DevOps credentials.
Type Field Use Case Git git_sourceGeneric Git repositories GitHub github_sourceGitHub.com or GitHub Enterprise GitLab gitlab_sourceGitLab.com or self-hosted GitLab SVN svn_sourceSubversion repositories
Trigger Multi-Branch Pipeline Run apiVersion: devops.kubesphere.io/v1alpha3
kind: PipelineRun
metadata:
name: demo-jenkinsfiles-go-main-run
namespace: demo-project
spec:
pipelineRef:
name: demo-jenkinsfiles-go
scm:
refName: main # Branch name
refType: branch # or 'tag'
Check Discovered Branches Via v1alpha3 API (preferred):
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches?filter=origin&page=1&limit=10" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" | jq -r '.items[] | "- Branch: \(.name) | Latest Run: \(.latestRun.id // "N/A") | Status: \(.latestRun.result // "N/A")"'
Via Jenkins (admin only):
kubectl run curl-jenkins --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/demo-project/job/demo-jenkinsfiles-go/api/json"
Trigger Repository Scanning
Note : Repository scanning uses v1alpha2 API (not v1alpha3). This is an exception to the general rule of preferring v1alpha3.
curl -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/scan" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{}'
Step 2: Fetch Scanning Log
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/consolelog" \
-H "Authorization: Bearer ${API_TOKEN}"
Force immediate repository re-scan
Discover new branches that aren't showing up
Troubleshoot branch detection issues
Example scanning log output:

Complete Private Repo Setup Example Scenario: Create a multi-branch pipeline for a private GitHub repository with proper authentication.
Step 1: Ask User About Repository Type
Question: "Is https://github.com/stoneshi-yunify/jenkinsfiles a private repository?"
User Answer: "Yes"
Step 2: Create GitHub Credential
export KUBESPHERE_API="http://kubesphere-apiserver:80"
export API_TOKEN="<tenant-oauth-token>"
export DEVOPS_PROJECT="devopstestc2nj7"
export USERNAME="stone-ns-admin"
export GITHUB_PAT="ghp_xxxxxxxxxxxxxxxxxxxx"
curl -s -X POST "${KUBESPHERE_API}/clusters/member-1/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/credentials" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
"apiVersion": "v1",
"kind": "Secret",
"metadata": {
"name": "github-token",
"namespace": "'${DEVOPS_PROJECT}'",
"annotations": {
"kubesphere.io/creator": "'${USERNAME}'",
"credential.devops.kubesphere.io/type": "basic-auth"
}
},
"stringData": {
"username": "git",
"password": "'${GITHUB_PAT}'"
},
"type": "credential.devops.kubesphere.io/basic-auth"
}'
Step 3: Create Multi-Branch Pipeline with Credential
curl -s -X POST "${KUBESPHERE_API}/clusters/member-1/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
"apiVersion": "devops.kubesphere.io/v1alpha3",
"kind": "Pipeline",
"metadata": {
"name": "echo-jenkinsfile-pipeline",
"namespace": "'${DEVOPS_PROJECT}'",
"annotations": {
"kubesphere.io/creator": "'${USERNAME}'"
}
},
"spec": {
"type": "multi-branch-pipeline",
"multi_branch_pipeline": {
"name": "echo-jenkinsfile-pipeline",
"description": "Multi-branch pipeline with GitHub auth",
"source_type": "git",
"git_source": {
"url": "https://github.com/stoneshi-yunify/jenkinsfiles.git",
"credential_id": "github-token",
"discover_branches": true,
"discover_tags": false
},
"script_path": "echo/Jenkinsfile"
}
}
}'
Note: The kubesphere.io/creator annotation is required for all pipelines (both regular and multi-branch). Without it, the pipeline may not appear correctly in the KubeSphere UI.
curl -s "${KUBESPHERE_API}/clusters/member-1/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/echo-jenkinsfile-pipeline" \
-H "Authorization: Bearer ${API_TOKEN}" | jq -r '{
name: .metadata.name,
syncStatus: .metadata.annotations."pipeline.devops.kubesphere.io/syncstatus",
credential: .spec.multi_branch_pipeline.git_source.credential_id
}'
{
"name": "echo-jenkinsfile-pipeline",
"syncStatus": "successful",
"credential": "github-token"
}
Complete Multi-Branch Workflow Example Scenario: Trigger build, monitor, retrieve logs, and download artifacts.
Step 1: Check Pipeline Exists
kubectl get pipelines -n demo-project
# NAME TYPE AGE
# demo-jenkinsfiles-go multi-branch-pipeline 12d
Step 2: Trigger Build via Jenkins API
# Get token
TOKEN=$(kubectl -n kubesphere-devops-system get secret devops-jenkins -o jsonpath='{.data.jenkins-admin-token}' | base64 -d)
# Trigger main branch build
kubectl run curl-trigger --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/demo-project/job/demo-jenkinsfiles-go/job/main/build" \
-X POST -w "\nHTTP Status: %{http_code}\n"
# Expected: HTTP Status: 201
Step 3: Monitor Build Status
# Check PipelineRun created
kubectl get pipelineruns -n demo-project --sort-by=.metadata.creationTimestamp | tail -3
# Example output:
# demo-jenkinsfiles-go-vf8p5 3 Succeeded 2m
# Get detailed status
# Or check via Jenkins API
kubectl run curl-status --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/demo-project/job/demo-jenkinsfiles-go/job/main/3/api/json" \
| grep -E '"result"|"building"|"duration"'
Step 4: Retrieve Console Log
# Get full console log from build #3
kubectl run curl-log --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/demo-project/job/demo-jenkinsfiles-go/job/main/3/consoleText"
# Look for:
# [Pipeline] Start of Pipeline
# [Pipeline] { (Clone Repository)
# [Pipeline] { (Run Tests)
# === RUN TestHello
# --- PASS: TestHello (0.00s)
# [Pipeline] End of Pipeline
# Finished: SUCCESS
Step 5: Download Build Artifacts
For binary artifacts, use pod-based download:
# Create download pod
kubectl run artifact-downloader --image=curlimages/curl -- sleep 300
kubectl wait --for=condition=Ready pod/artifact-downloader --timeout=60s
# Download artifact inside pod
TOKEN=$(kubectl -n kubesphere-devops-system get secret devops-jenkins -o jsonpath='{.data.jenkins-admin-token}' | base64 -d)
kubectl exec artifact-downloader -- sh -c \
"curl -s -o /tmp/service 'http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/demo-project/job/demo-jenkinsfiles-go/job/main/3/artifact/service'"
# Copy to local
kubectl cp artifact-downloader:/tmp/service /tmp/service
# Clean up
kubectl delete pod artifact-downloader --force
Step 6: Verify Downloaded Artifact
# Check file details
ls -lh /tmp/service
file /tmp/service
# Expected output:
# /tmp/service: ELF 64-bit LSB executable, x86-64...
# Make executable and test
chmod +x /tmp/service
/tmp/service --help
Build #3 Summary:
- Status: SUCCESS
- Duration: ~54 seconds
- Test Results: 1/1 passed
- Artifact: service (8.0 MB Go binary)
- Stages: Checkout → Clone → Dependencies → Test → Build → Archive
Multi-Branch vs Regular Pipeline Feature Regular Pipeline Multi-Branch Pipeline Type pipelinemulti-branch-pipelineJenkinsfile Inline in CRD From SCM (script_path) Branches Single Auto-discovered SCM Config Manual checkout Automatic Trigger PipelineRun/API Branch indexing + webhooks Get Parameters From .spec.pipeline.jenkinsfile From /branches/{branch} endpoint
Triggering Regular Pipeline Runs with Parameters (v1alpha3 API) For regular pipelines, use this two-step procedure to handle parameters:
Step 1: Get Pipeline Definition and Extract Parameters Unlike multi-branch pipelines, regular pipelines don't have a dedicated /parameters endpoint. Instead, retrieve the Pipeline CR and extract parameters from the Jenkinsfile:
# Get the pipeline definition
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" | jq -r '.spec.pipeline.jenkinsfile'
Look for the parameters {} directive in the Jenkinsfile:
pipeline {
agent any
stages {
stage('Example') {
steps {
echo "Hello ${params.PERSON}"
}
}
}
parameters {
string(name: 'PERSON', defaultValue: 'Mr Jenkins', description: 'Who should I say hello to?')
booleanParam(name: 'TOGGLE', defaultValue: true, description: 'Toggle this value')
choice(name: 'CHOICE', choices: ['One', 'Two', 'Three'], description: 'Pick something')
}
}
Parameter Types in Jenkinsfile:
Directive Type Example string()Single-line text string(name: 'VAR', defaultValue: 'default', description: '...')text()Multi-line text text(name: 'VAR', defaultValue: '', description: '...')booleanParam()True/false booleanParam(name: 'FLAG', defaultValue: true, description: '...')choice()Dropdown choice(name: 'ENV', choices: ['dev', 'prod'], description: '...')password()Hidden value password(name: 'SECRET', defaultValue: '', description: '...')
Step 2: Trigger Pipeline with Parameters Use the /pipelineruns endpoint to create a new run with parameters:
# Trigger with parameters
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/pipelineruns" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
"parameters": [
{"name": "PERSON", "value": "John Doe"},
{"name": "TOGGLE", "value": "true"},
{"name": "CHOICE", "value": "Two"}
]
}' | jq -r '.metadata.name'
No branch query parameter needed (regular pipelines have no branches)
Parameters are passed in the request body as a JSON array
Boolean values must be strings: "true" or "false"
The response includes the created PipelineRun resource with your parameters
Complete Example for Regular Pipelines #!/bin/bash
export KUBESPHERE_API="http://kubesphere-apiserver:80"
export API_TOKEN="<tenant-oauth-token>"
export DEVOPS_PROJECT="devopstestc2nj7"
export PIPELINE_NAME="my-regular-pipeline"
# Step 1: Get pipeline definition and check for parameters
echo "Checking for parameters in pipeline..."
JENKINSFILE=$(curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}" \
-H "Authorization: Bearer ${API_TOKEN}" | jq -r '.spec.pipeline.jenkinsfile')
# Check if parameters exist
if echo "$JENKINSFILE" | grep -q "parameters {"; then
echo "Pipeline has parameters defined. Extracting..."
# In practice, parse the Jenkinsfile to extract parameter names and defaults
echo "$JENKINSFILE" | grep -E "(string|booleanParam|choice|password|text)\(name:"
else
echo "No parameters found. Triggering without parameters."
fi
# Step 2: Trigger with parameters
echo "Triggering pipeline with parameters..."
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/pipelineruns" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
"parameters": [
{"name": "PERSON", "value": "Test User"},
{"name": "TOGGLE", "value": "true"},
{"name": "CHOICE", "value": "Two"},
{"name": "BIOGRAPHY", "value": "Testing API"},
{"name": "PASSWORD", "value": "secret123"}
]
}' | jq -r '.metadata.name'
Triggering Multi-Branch Pipeline Runs (v1alpha3 API)
⚠️ API Version Notice : The /kapis/devops.kubesphere.io/v1alpha2/ APIs are deprecated. Always prefer v1alpha3 APIs when available.
For multi-branch pipelines, use this three-step procedure with v1alpha3 APIs:
Step 1: List Available Branches curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches?filter=origin&page=1&limit=10" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" | jq -r '.items[] | "- Branch: \(.name) | Latest Run: \(.latestRun.id // "N/A") | Status: \(.latestRun.result // "N/A")"'
- Branch: main | Latest Run: 2 | Status: SUCCESS
- Branch: stone | Latest Run: 1 | Status: SUCCESS
Step 2: Ask User Which Branch to Build Present the available branches to the user and ask:
"Which branch would you like to build?"
Step 3: Trigger Build on Selected Branch export BRANCH="main" # User's selection
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/pipelineruns?branch=${BRANCH}" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{"parameters":[]}' | jq -r '.metadata.name'
Use v1alpha3 endpoint (not v1alpha2)
Pass branch as query parameter ?branch=${BRANCH}
Returns a PipelineRun resource (Kubernetes CRD format)
The PipelineRun name is auto-generated with the pipeline name as prefix
Triggering with Parameters When a pipeline has parameters defined in the Jenkinsfile, you can provide values when triggering a build. Follow this workflow:
Step 1: Get Available Parameters Query the branch to retrieve parameter definitions:
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches/${BRANCH}" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" | jq '.parameters'
[
{
"description": "Who should I say hello to?",
"name": "PERSON",
"type": "StringParameterDefinition",
"value": "",
"defaultParameterValue": {
"name": "PERSON",
"value": "Mr Jenkins"
}
},
{
"description": "Toggle this value",

"type": "BooleanParameterDefinition",
"value": "",
"defaultParameterValue": {
"name": "TOGGLE",
"value": true
}
},

"type": "ChoiceParameterDefinition",
"value": "",
"defaultParameterValue": {
"name": "CHOICE",
"value": "One"
},
"choices": ["One", "Two", "Three"]
}
]
Type Description Value Format StringParameterDefinitionSingle-line text "value": "text"TextParameterDefinitionMulti-line text "value": "multi\\nline"BooleanParameterDefinitionTrue/false toggle "value": "true" or "value": "false"ChoiceParameterDefinitionPredefined options "value": "Option" (must match one of choices)PasswordParameterDefinitionHidden value "value": "secret"
Step 2: Build Parameters Array Create the parameters JSON array with user-provided values:
# Example parameters
cat > params.json << 'EOF'
{
"parameters": [
{"name": "PERSON", "value": "stone"},
{"name": "BIOGRAPHY", "value": "i'm a software engineer"},
{"name": "TOGGLE", "value": "true"},
{"name": "CHOICE", "value": "Two"},
{"name": "PASSWORD", "value": "secret123"}
]
}
EOF
Boolean values must be strings: "true" or "false"
Use the name field, not the description
Omit parameters to use their default values
Step 3: Trigger Build with Parameters export BRANCH="main"
# Trigger with parameters
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/pipelineruns?branch=${BRANCH}" \
-H "Authorization: Bearer ${API_TOKEN}" \

Handling Paused Pipeline Steps with Input When a pipeline reaches an input step (e.g., approval gates), it enters the PAUSED state and waits for user interaction. Tenants can approve or reject these steps via the KubeSphere API.
Step 1: Get Node Details to Find Input Step Use the nodedetails endpoint to identify the paused step with input:
# Get node details for the pipeline run
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelineruns/${PIPELINE_RUN_NAME}/nodedetails" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" | jq '.[-1]'
Look for steps with approvable: true:
{
"displayName": "Build Binary",
"id": "38",
"state": "PAUSED",
"steps": [
{
"id": "41",
"displayName": "Wait for interactive input",
"state": "PAUSED",
"input": {
"id": "Build-binary-confirm",
"message": "Build binary now?",
"ok": "Proceed"
},
"approvable": true
}
]
}
Field Description steps[].idStep ID (e.g., "41") steps[].input.idInput action ID (e.g., "Build-binary-confirm") steps[].approvabletrue if this step can be approved/rejected
Step 2: Approve or Reject the Input Step Use the v1alpha2 API to submit your decision:
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches/${BRANCH}/runs/${JENKINS_RUN_ID}/nodes/${NODE_ID}/steps/${STEP_ID}/" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{"id":"${INPUT_ID}","abort":false}'
curl -s -X POST "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches/${BRANCH}/runs/${JENKINS_RUN_ID}/nodes/${NODE_ID}/steps/${STEP_ID}/" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{"id":"${INPUT_ID}","abort":true}'
Parameter Description Example JENKINS_RUN_IDJenkins build number 9NODE_IDStage/node ID from nodedetails 38STEP_IDStep ID from nodedetails 41INPUT_IDInput ID from the input object Build-binary-confirmabortfalse to proceed, true to abortfalse

# Step 1: Get nodedetails and extract input information
NODES=$(curl -s "${KUBESPHERE_API}/clusters/member-1/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelineruns/${PIPELINE_RUN_NAME}/nodedetails" \
-H "Authorization: Bearer ${API_TOKEN}")
# Extract the last node (current stage) and find approvable step
NODE_ID=$(echo "$NODES" | jq -r '.[-1].id')
STEP_ID=$(echo "$NODES" | jq -r '.[-1].steps[] | select(.approvable == true) | .id')
INPUT_ID=$(echo "$NODES" | jq -r '.[-1].steps[] | select(.approvable == true) | .input.id')
JENKINS_RUN_ID=$(echo "$NODES" | jq -r '.[-1].steps[] | select(.approvable == true) | .jenkinsRunId // "9"')
echo "Approving step ${STEP_ID} in node ${NODE_ID}"
echo "Input ID: ${INPUT_ID}"
# Step 2: Approve the step
curl -s -X POST "${KUBESPHERE_API}/clusters/member-1/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches/${BRANCH}/runs/${JENKINS_RUN_ID}/nodes/${NODE_ID}/steps/${STEP_ID}/" \
-H "Authorization: Bearer ${API_TOKEN}" \
-H "Content-Type: application/json" \
-d "{\"id\":\"${INPUT_ID}\",\"abort\":false}"
# Step 3: Verify the pipeline continues
echo "Pipeline resumed. Check status..."
This approach works for tenants (no cluster-admin access required)
Uses v1alpha2 API for the approval action (not available in v1alpha3)
The trailing slash / in the URL is required
Empty response usually indicates success (HTTP 200)
Retrieving Build Logs via KubeSphere API To retrieve build logs through the KubeSphere API (recommended for tenants):
Step 1: Get Jenkins PipelineRun ID First, get the Jenkins PipelineRun ID from the PipelineRun CR annotation:
# Get fresh token
TOKEN_RESPONSE=$(curl -s -X POST "${KUBESPHERE_API}/oauth/token" \
-H "Content-Type: application/x-www-form-urlencoded" \
--data-urlencode 'grant_type=password' \
--data-urlencode "username=${USERNAME}" \
--data-urlencode "password=${PASSWORD}" \
--data-urlencode 'client_id=kubesphere' \
--data-urlencode 'client_secret=kubesphere')
export API_TOKEN=$(echo "$TOKEN_RESPONSE" | jq -r '.access_token')
# Get Jenkins PipelineRun ID from annotation
JENKINS_ID=$(curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelineruns/${PIPELINE_RUN_NAME}" \
-H "Authorization: Bearer ${API_TOKEN}" \
| jq -r '.metadata.annotations."devops.kubesphere.io/jenkins-pipelinerun-id"')
echo "Jenkins Run ID: $JENKINS_ID"
Step 2: Fetch Logs Use the v1alpha2 API to fetch logs. Note: The ?start=0 parameter is required for tenant access:
# For multi-branch pipelines
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches/${BRANCH}/runs/${JENKINS_ID}/log/?start=0" \
-H "Authorization: Bearer ${API_TOKEN}"
# Example:
curl -s "${KUBESPHERE_API}/clusters/member-1/kapis/devops.kubesphere.io/v1alpha2/namespaces/devopstestc2nj7/pipelines/echo-jenkinsfile-pipeline/branches/main/runs/5/log/?start=0" \
-H "Authorization: Bearer ${API_TOKEN}"
Use the jenkins-pipelinerun-id annotation (not the Kubernetes PipelineRun name)
For multi-branch pipelines: include /branches/{branch}/ in the path
CRITICAL: Include ?start=0 query parameter - required for tenant accessThe trailing slash / at the end of the URL path is required
Works with tenant credentials (no cluster-admin access needed)
Retrieving Build Artifacts via KubeSphere API To query and download build artifacts through the KubeSphere API:
Step 1: List Artifacts Query artifacts for a specific run:
curl -s "${KUBESPHERE_API}/clusters/${CLUSTER}/kapis/devops.kubesphere.io/v1alpha2/namespaces/${DEVOPS_PROJECT}/pipelines/${PIPELINE_NAME}/branches/${BRANCH}/runs/${JENKINS_ID}/artifacts/?start=0&limit=10" \
-H "Authorization: Bearer ${API_TOKEN}"
[
{
"name": "service",
"path": "service",
"size": 8344228,
"downloadable": true,
"url": "/job/devopstestc2nj7/job/go-pipeline/job/main/2/artifact/service"
}
]
Step 2: Download Artifact Download a specific artifact by filename:
curl -s -o service "${KUBESPHERE_API}/kapis/clusters/${CLUSTER}/devops.kubesphere.io/v1alpha3/namespaces/${DEVOPS_PROJECT}/pipelineruns/${PIPELINE_RUN_NAME}/artifacts/download?filename=service" \
-H "Authorization: Bearer ${API_TOKEN}"
Use the Kubernetes PipelineRun name (not Jenkins ID) for the download endpoint
The filename must match exactly what's listed in the artifacts query
Supports pagination with start and limit parameters for listing
Works with tenant credentials (no cluster-admin access needed)
Querying Jenkins Directly For debugging, you can query Jenkins directly using the admin token:
# Get Jenkins admin token
TOKEN=$(kubectl -n kubesphere-devops-system get secret devops-jenkins -o jsonpath='{.data.jenkins-admin-token}' | base64 -d)
# List all folders (maps to DevOpsProjects)
kubectl run curl-jenkins --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/api/json" \
-H "Content-Type: application/json"
# List jobs in a specific folder
kubectl run curl-jenkins --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/demo-project/api/json" \
-H "Content-Type: application/json"
Common Mistakes Mistake Fix PipelineRun not triggering Check Pipeline exists and is synced to Jenkins Controller panic (getAgentInfo nil pointer) Known issue with PipelineRef; use Jenkins API directly as workaround Agent label not found Check available labels: kubectl run curl-jenkins --rm -i --restart=Never --image=curlimages/curl -- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/labelsdashboard/labelsData" Go/Tool not found in agent Use kubernetes { yaml ... } agent with appropriate container image Artifact not found Run archiveArtifacts in the same stage where the file was created (same workspace) Permission denied Check DevOps project membership and RBAC Pipeline shows in KubeSphere but not Jenkins Check sync status annotation: pipeline.devops.kubesphere.io/syncstatus Run fails immediately Check controller logs: kubectl logs -n kubesphere-devops-system deployment/devops-controller Escape characters in Jenkinsfile Don't use \$class escape sequences in inline Jenkinsfile
Debugging Steps
Check PipelineRun status:
kubectl get pipelinerun <name> -n <namespace> -o yaml
Check Jenkins build directly:
# Get admin token
TOKEN=$(kubectl -n kubesphere-devops-system get secret devops-jenkins -o jsonpath='{.data.jenkins-admin-token}' | base64 -d)
# Get console output
kubectl run curl-jenkins --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/job/<project>/job/<pipeline>/<build>/consoleText"
List Jenkins agent labels:
kubectl run curl-jenkins --rm -i --restart=Never --image=curlimages/curl \
-- "http://admin:${TOKEN}@devops-jenkins.kubesphere-devops-system:80/labelsdashboard/labelsData"
Mistake Fix PipelineRun not triggering Check Pipeline exists and is synced to Jenkins Agent not found Verify Jenkins agent labels match pipeline's agent { label 'xxx' } Permission denied Check DevOps project membership and RBAC Pipeline shows in KubeSphere but not Jenkins Check sync status annotation: pipeline.devops.kubesphere.io/syncstatus Run fails immediately Check controller logs: kubectl logs -n kubesphere-devops-system deployment/devops-controller
Best Practices
Use PipelineRun CRDs for triggering - it's the cloud-native approachCheck status via kubectl rather than polling APIsUse kubectl logs on the PipelineRun controller for debuggingVerify sync status - pipelines must sync to Jenkins before they can run
