Can a Docker container run as a Jenkins build node with both Java 11 and Java 8?

  • 772

I have a customer who is excited about the idea of Docker containers as Jenkins build nodes, but a few of their pipelines still have dependencies on Java 8. Can a Docker container have Java 11 and Java 8, use 11 to run as an agent but 8 to execute a pipeline?

    Sure. You can install java 11 in one location, and use java 8 as default. Something in the line (pseudo file):

    # Dockerfile
FROM: …
COPY java11.tar /opt

RUN yum/apt install java8
# make sure java8 in default path

CMD [“/opt/java11/bin/java -jar jenkis-slave.jar”]

    Keep in mind, that final container will be ~400MB
