alpine based Docker image for the Heroku CLI

Alpine Heroku CLI

This image packages the Heroku CLI inside an Alpine Linux based Docker container. The version will track that of the Heroku CLI.

Usage

The easiest way to use this would be to use your Heroku API key or an OAuth authorization token set as the HEROKU_API_KEY environment variable.

Another method would be to mount your ~/.netrc as a volume on the docker container. This would use your local Heroku login credentials for authentication.

docker run wingrunr21/alpine-heroku-cli version
# heroku-cli/5.6.12-c892d56 (linux-amd64) go1.6.3

# API key/OAuth token method
docker run --rm -e HEROKU_API_KEY="abc-123123123" wingrunr21/alpine-heroku-cli list
# == Collaborated Apps
# app1
# app2
# ...
docker run --rm -v ~/.netrc:/root/.netrc:ro wingrunr21/alpine-heroku-cli list
# == Collaborated Apps
# app1
# app2
# ...

Alias

Another option is to create an alias on ~/.bashrc or ~/.zshrc to map to heroku inside docker.

alias heroku="touch ~/.netrc && docker run --rm -it -v ~/.netrc:/root/.netrc -v $(pwd):/app -w /app brunodles/alpine-heroku-cli"

This alias have one "setup step" to make everything work fine.

• Create a .netrc file inside user home
• Run docker command

This docker command will:

• Remove itself on the end
• Make a link between host and guest .netrc files. (it's a volume)
• Make a volume with local folder and app folder inside container

This will ensure you can run Heroku CLI as usual.
