jenkins-nvm-agent

This agent builds on the jenkins-agent by adding the ability to start the container with any nvm available Node.js version. Nvm is available to user root and jenknis.

The jenkins user can install npm items globally without having to run as root.

Usage

docker run jenkins-nvm-agent will start the container with the default Node.js version (v10.11.0).

To switch, set NODE_JS_NVM_VERSION environment variable to the desired version on the docker run command:

docker run -e "NODE_JS_NVM_VERSION=8.12.0" jenkins-nvm-agent

Any arguments that appear after the image name will be passed to exec "$@" in the docker-entrypoint.sh script.

Node and NVM install

Nvm is used to manage local versions of Node.js for user root and user jenkins.

When the container starts, the value set by NODE_JS_NVM_VERSION environment variable is passed to nvm. The default specified within the image (globally and nvm) is the Node.js "current" (currently at v10.11.0).

This image also includes the following packages:

• build-essential - Enables the image to install and run NPM packages that require a C compiler.
• expect - Enables the image to respond to terminal prompts. Useful for things such as logging into an npm registry for automatic publishing.
• maven & ca-certificates-java - Enables the image to contact maven central using the proper ssl certificates

Docker run with CLI arguments

See branch run_cli_args for the version of the image that allows passing the Node.js version as a CLI argument on docker run rather than env vars.
