docker-cheat

docker-cheat provides a single docker image for cheat and its community-sourced cheatsheets to simplify installation.

Prerequisites

  • Docker

Installation

  1. Create a cheat alias by adding the following line to ~/.profile:
    alias cheat='docker run --rm bannmann/docker-cheat'
    
  2. Rejoice!

Updating

Using the command above will not pick up new image versions automatically. To do that, execute the following command manually:

docker pull bannmann/docker-cheat

You could automate this process using a cron job, but make sure that cron only emails the command output in case of errors.

Using custom cheatsheets

In addition to the community cheatsheets, you can use custom cheatsheets by mapping directories to the following paths inside the docker image:

To use both options, set up your cheat alias as follows:

alias cheat='docker run -v ~/.cheat:/v/personal:ro -v $(pwd):/v/workdir:ro --rm bannmann/docker-cheat'

Built-in cheatsheet

The docker image includes a built-in cheatsheet that can be displayed via cheat docker-cheat.

Limitations

  • Editing cheatsheets is not supported as the docker image intentionally does not include an editor.
  • cheat configuration settings are currently hard-coded inside the container.
  • Although the latest tag on Docker Hub is rebuilt for each new commit on the master branch, new versions of the cheat binary and cheatsheets are not picked up automatically yet. Instead, every once in a while, the respective definitions (Dockerfile and the cheatsheets submodule) will be updated with a manual commit. This will probably be automated at some point.
