docker image for jenkins

To pull this image: docker pull mbentley/jenkins

⁠Jenkins Controller

Example usage:

docker run -d \
  --name jenkins \
  -p 8080:8080 \
  -e JAVA_OPTS="-XX:+UseG1GC -XX:MaxRAMPercentage=50.0 -XX:InitialRAMPercentage=25.0 -XX:+DisableExplicitGC -Xlog:gc" \
   mbentley/jenkins

Note: Jenkins runs as the user jenkins in the container. The jenkins user uid & gid are 510 in case a volume is used for the data in /var/lib/jenkins.

⁠Jenkins Agent

Example usage:

docker run -d \
  --name jenkins-agent \
  -e JENKINS_URL="https://jenkins.example.com/" \
  -e JENKINS_SECRET="myjenkinsnodesecretgoeshere" \
  -e WEBSOCKET=true \
  -e NODE_NAME="agent1" \
  -e MAX_MEMORY="2g" \
  -e JAVA_OPTS="-XX:+UseG1GC -XX:+DisableExplicitGC -Xlog:gc" \
   mbentley/jenkins:agent

⁠Additional Options

• MAX_MEMORY - optional fixed heap size (sets -Xmx and -Xms); if unset on the controller, the heap is sized by MaxRAMPercentage/InitialRAMPercentage in JAVA_OPTS (the agent image defaults to 2g)
• CUSTOM_OPTS - append additional options instead of completely overriding JAVA_OPTS
• TUNNEL - set the -tunnel value for a Jenkins agent if using the TCP port
