phlummox/heroku-cli repository overview

⁠use the Heroku cli without having to install the tool yourself

(Heroku want you to install it as root, and to use a custom Node.js installation, AND remove your existing one.)

Step 1: create a vol with your authentication details in it

docker -D run -it --name heroku-config phlummox/heroku-cli:0.1 heroku login

(don't use --rm cos auths persist in the container.)

Then, as long as that volume heroku-config still exists, we can do

Step 2: run a CLI command

docker run --rm -ti --volumes-from heroku-config \
  -v $PWD:/opt/work --workdir /opt/work phlummox/heroku-cli:0.1 heroku --version

(Trick shamelessly stolen from https://hub.docker.com/r/google/cloud-sdk/⁠.)

Or, to make things more convenient:

alias heroku="docker run --rm -ti --volumes-from heroku-config \
  -v $PWD:/opt/work --workdir /opt/work phlummox/heroku-cli:0.1 heroku"

Many thanks to @mhart for his alpine-node⁠ image, which made this one possible. Or much simpler, anyway.
