⁠Jenkins swarm slave preconfigured for Polymer-CLI

This image is a preconfigured openjdk instance which can auto-allocate and de-allocate itself as a node with a master Jenkins instance. Additional reading on how the Swarm Plugin works in general can be found in the resources section below.

You can use this image to run a node used with a typical pipeline file, no extra volume/workspace share magic here.

Pre-installed:

• NodeJS 8
• NPM 4
• Bower
• Gulp 4 (with cli)
• Polymer-CLI (latest)
• Chrome (latest)
• Firefox (extended support version)
• OpenJDK
• XVFB

Not yet installed:

This image requires a Jenkins instance with Swarm Plugin⁠ installed.

Resources

• Swarm Plugin documentation: https://wiki.jenkins.io/display/JENKINS/Swarm+Plugin⁠
• Base swarm slave image (thanks to Carlos Sanchez⁠ for maintaining!) :
  • Github: carlossg/jenkins-swarm-slave-docker⁠
  • Dockerhub: csanchez/jenkins-swarm-slave⁠

⁠Running

To run a Docker container passing any parameters⁠ to the slave

It is recommended that a label be specified for ease of selection in your pipeline. jenkins:jenkins is used here for an example password combination.

The base image attempts to connect to http://jenkins:8080⁠ by default.

Run with direct connection to a Jenkins master not located at the default address:

• docker run krumware/jenkins-slave-polymer -master http://other-jenkins:8080⁠ -username jenkins -password jenkins -executors 1 -labels polymer

Run in a service stack with linking to the Jenkins master container

• docker run --link jenkins:jenkins krumware/jenkins-slave-polymer -username jenkins -password jenkins -executors 1 -labels polymer

⁠Troubleshooting

• Currently, it looks like the base image sometimes has trouble in stack configurations where environmental variables are designated. You can get around this by passing cmd line args as the command. For example: -username jenkins -password jenkins -executors 1 -labels polymer

⁠Building

docker build -t krumware/jenkins-slave-polymer .
