# Jenkins Manage Jenkins jobs, builds, and pipelines via the REST API. ## Environment Variables - `JENKINS_URL` - Jenkins server URL (e.g. `https://jenkins.example.com`) - `JENKINS_USER` - Jenkins username - `JENKINS_TOKEN` - API token (generate from user profile > Configure > API Token) ## List jobs ```bash curl -s -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/api/json?tree=jobs[name,color,url]" | jq '.jobs[] | {name, color, url}' ``` ## Get job info ```bash curl -s -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/job/my-pipeline/api/json?tree=name,color,lastBuild[number,result,timestamp]" | jq . ``` ## Trigger build ```bash curl -s -X POST -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/job/my-pipeline/build" echo "Build triggered" ``` ## Trigger build with parameters ```bash curl -s -X POST -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/job/my-pipeline/buildWithParameters" \ --data-urlencode "BRANCH=main" \ --data-urlencode "ENV=staging" echo "Parameterized build triggered" ``` ## Get build status ```bash curl -s -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/job/my-pipeline/lastBuild/api/json?tree=number,result,duration,timestamp,building" | jq . ``` ## Get build console output ```bash curl -s -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/job/my-pipeline/lastBuild/consoleText" | tail -50 ``` ## List build queue ```bash curl -s -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/queue/api/json?tree=items[task[name],why,inQueueSince]" | jq '.items[] | {job: .task.name, why, since: .inQueueSince}' ``` ## Get pipeline stages (Blue Ocean) ```bash curl -s -u "$JENKINS_USER:$JENKINS_TOKEN" \ "$JENKINS_URL/blue/rest/organizations/jenkins/pipelines/my-pipeline/runs/1/nodes/" | jq '.[] | {displayName, result, durationInMillis}' ``` ## Notes - Jenkins uses crumb-based CSRF protection; if enabled, fetch crumb first. - Use `buildWithParameters` for parameterized jobs, `build` for simple jobs. - API token is preferred over password for authentication. - Always confirm before triggering builds.
