The Docker Way

Docker Pulls

$ docker pull gaocegege/maintainer
$ docker run --rm -v $(pwd):/workdir gaocegege/maintainer:latest --help


There is only one configuration now: the token in GitHub. The token can be created from, you only need "repo" scope for private repositories.

It is used in changelog subcommand, so there are three ways to config the token:

  • Config token field in $HOME/.maintainer.yml. ./.maintainer.yml.template is a template.
  • Or Set environment variable MAINTAINER_TOKEN.
  • Or Set the flag in changelog subcommand: maintainer changelog --token <token>. If you set it in command, it will override the configuration in config file and the environment variable.

Features Preview



changelog subcommand will generate for your repository, it is supported via github_changelog_generator, so you need to install it before the subcommand is called.

See here about how to install github_changelog_generator. In the future, maintainer will support install this dependency automatically.

See as an example.


contributing subcommand will generate for your repository, now this file is a general version.

In the future, maintainer will detect languages and generate corresponding documentation about programming language specific flow for contribution.

See as an example.


contributor subcommand will generate AUTHORS just like moby/moby does. It gives the contributors more passion to contribute.

See as an example.

Generate Personal Daily Report or Summary

user daily and user summary subcommands will generate daily report or summary for the given user.

maintainer user --username gaocegege daily
maintainer user --username gaocegege summary --begin 2019-05-20 --end 2019-05-22

See or as an example.

Please notice that GitHub only shows the first 300 events for one user which is a core limitation for this feature.

  • toc subcommand, which could generate table of contents(TOC) for It is supported with gh-md-toc, so you need to install it before the subcommand is called.

CLI references



Run from source code

go run main.go <subcommand>

Build Docker image

Maintainer requires two steps to build a Docker image.

  1. scripts/ builds maintainer in a Docker container which from golang:1.8-alpine. It mounts maintainer directory into the container so the maintainer built from code will visiable in host.
  2. docker build -t maintainer . builds real image from Dockerfile. It simply copys binary maintainer into the image and install some dependencies such as git and github_changelog_generator.

This way is inspired by caicloud/cyclone. It could reduce the size of image significantly.
