DoDocker

CLI tool helper for fast image building with tags based on git revision. If you wish to push to repository you need to run docker login <REPOSITORY> before using DoDocker.

Available CLI options

  -V, --version                          output the version number
  -c, --config                           Path to config file (if different than .dodocker)
  -p, --push                             Push image to repository
  -l, --latest                           Push as latest
  -r, --repository [repository]          Docker repository
  -s, --scope [scope]                    Docker image scope
  -n, --image-name [image-name]          Docker image name
  -R, --run                              Run Docker image in container (detached mode)
  -P, --port [port]                      Expose container port
  -N, --container-name [container-name]  Container name
  -F, --force                            Delete already running instance of container if required
  -h, --help                             output usage information

If you do not wish to provide repository and image name for every run please create .dodocker file based on example below. Values provided in this file will be used as defaults, but can be overwritten by CLI options.

module.exports = {
  // image props
  repository: '', // repository name
  scope: '',      // image scope inside repository
  name: '',       // image name
  // container props
  container: '',  // container name
  port: '',       // container expose port
  // git tag -> docker tag logic
  tag: {          // default below
    predicate: tag => tag && /^([\w\d.+\-]+)$/i.test(tag),            // method checking if tag is ok to use as docker image tag
    format: tag => tag.replace('+', '_')                              // method formatting tag to desired format
  },
  branch: {       // default below
    predicate: branch => branch && /^([\w\d.\/\-]+)$/i.test(branch),  // method checking if branch name is ok to use as docker image tag
    format: branch => branch.replace('/', '_')                        // method formatting branch name to desired format
  },
  // build-arg passing
  arguments: ({ tag, branch, commit }) => []  // method feeding build args to image build based on git revision (optional, should return String[])
};

Example usage:

Git revision	.dodocker	output
master #1.9.2	{ repository: 'docker.eg.com', name: 'example' }	docker image build -tag docker.eg.com/example:1.9.2
release/1.10.0	{ repository: 'docker.eg.com', name: 'example' }	docker image build -tag docker.eg.com/example:release_1.10.0
release/2.0.0 #2.0.0-rc.2+asdf	{ repository: 'docker.eg.com', name: 'example' }	docker image build -tag docker.eg.com/example:2.0.0-rc.1_asdf
develop	{ repository: 'docker.eg.com', name: 'example' }	docker image build -tag docker.eg.com/example:develop
develop	{ repository: 'docker.eg.com', scope: 'project', name: 'component' }	docker image build -tag docker.eg.com/project/component:develop

Advanced usage:

// .dodocker content
module.exports = {
  repository: 'docker.eg.com',
  scope: 'project',
  name: 'component',
  container: 'component',
  port: '8080:80',
  arguments: revision => {
    return ['REVISION=' + (revision.tag ? revision.tag : revision.branch + ' @ ' + revision.commit)];
  }
};
