rockerc

Continuous Integration Status

Installation

Recommended Method:

Install pipx (if not already installed):

sudo apt install pipx
pipx ensurepath

Then install rockerc and its dependencies globally with:

pipx install --include-deps rockerc

This will ensure that rockerc and rocker commands are available on your PATH.

Usage

navigate to a directory with a rockerc.yaml file and run:

rockerc 

This will search recursively for rockerc.yaml and pass those arguments to rocker

Motivation

Rocker is an alternative to docker-compose that makes it easier to run containers with access to features of the local environment and add extra capabilities to existing docker images. However rocker has many configurable options and it can get hard to read or reuse those arguments. This is a naive wrapper that read a rockerc.yaml file and passes them to rocker. There are currently no plans to integrate docker-compose like functionalty directly into rocker so I made this as a proof of concept to see what the ergonomics of it would be like.

Caveats

I'm not sure this is the best way of implementing rockerc like functionality. It might be better to implmented it as a rocker extension, or in rocker itself. This was just the simplest way to get started. I may explore those other options in more detail in the future.

rocker.yaml configuration

You need to pass either a docker image, or a relative path to a dockerfile

rockerc.yaml

image: ubuntu:22.04

or

dockerfile: Dockerfile

will look for the dockerfile relative to the rockerc.yaml file
