A node.js build environment inside a docker container.
Full Description

nodejs-build-agent

https://github.com/allenevans/nodejs-build-agent

nodejs-build-agent is a "docker in docker" image designed as a tool for building Dockerized node.js projects hosted in git repositories.

How it works

The running nodejs-build-agent container links through to the host machine's docker instance via volume mapping to /var/run/docker.sock pipe. This gives the running container access to the hosts docker instance without having to actually include docker within the build agent image.

Build Process

  • Clone git repository
  • Build the Dockerfile in the root directory of the repository with the docker build command.
  • Write a build result .json file out to /build

How to run

    docker run --rm -i 
        -v /var/run/docker.sock:/var/run/docker.sock
        -v <local-build-results-folder>:/builds:rw 
        -v <path-to-ssh-keys>:/ssh
        --env TAG=<tag>
        --env REPO=<repository> 
        --env BUILD_ID=<buildId> 
        nodejs-build-agent:6.9.5

E.g.

    docker run --rm -i 
        -v /var/run/docker.sock:/var/run/docker.sock
        -v /home/user/build-results:/builds:rw 
        -v /home/user/.ssh:/ssh
        --env TAG=0.0.1
        --env REPO=https://github.com/somerepo.git
        --env BUILD_ID=1 
        nodejs-build-agent:6.9.5

Arguments

  • <local-build-results-folder> Folder where the build result file is written to once the build has completed.
  • <path-to-ssh-keys> Optional. Folder containing ssh keys used to authenticate during git clone.
  • <tag> This is the build tag that is passed through to docker build.
  • <repository> The git repository to clone.
  • <buildId> An identifier for the instance of the build e.g. 123. This forms the filename of the build result file e.g. build-123.json.

Notes

To automatically authenticate with a git repository using ssh, add a config file into the same folder as the ssh keys.

For example, to authenticate with bitbuket.org and automatically accept the hosts RSA key fingerprint, create the following file:-

```bash
Host bitbucket.org
    Hostname 104.192.143.2
    StrictHostKeyChecking no

IMPORTANT This is a potential security issue as it opens you up to a man-in-the-middle type attack. An alternative would be to use known_hosts.
