Jenkins Agent Docker image
This is a base image for Docker, which includes OpenJDK 8 and the Jenkins agent executable (slave.jar). This executable is an instance of the Jenkins Remoting library.
This image is used as the basis for the Docker JNLP Agent image. In that image, the container is launched externally and attaches to Jenkins.
This image may instead be used to launch an agent using the Launch method of Launch agent via execution of command on the master. Try for example
docker run -i --rm --name agent --init jenkins/slave java -jar /usr/share/jenkins/slave.jar
after setting Remote root directory to
Agent Work Directories
Starting from Remoting 3.8 there is a support of Work directories, which provides logging by default and change the JAR Caching behavior.
docker run -i --rm --name agent1 --init -v agent1-workdir:/home/jenkins/agent jenkins/slave java -jar /usr/share/jenkins/slave.jar -workDir /home/jenkins/agent
The image has several supported configurations, which can be accessed via the following tags:
latest: Latest version with the newest remoting (based on
latest-jdk11: Latest version with the newest remoting and Java 11 (based on
alpine: Small image based on Alpine Linux (based on
2.62: This version bundles Remoting 2.x, which is compatible with Jenkins servers running on Java 6 (
2.62-alpine: Small image with Remoting 2.x
2.62-jdk11: Versioned image for Java 11
Java 11 Support
Java 11 support is available in a preview mode. Only Debian-based images are provided right now. (see JENKINS-54487). There is a probability that images for Java 11 will be changed to AdoptOpenJDK before the final release of Java 11 support in Jenkins.
