Docker image for Hombrew on Amazon Linux 2
Most developers end up using opinionated system package managers (yum, apt-get, etc.)
Homebrew is so far the only package manager that's compatible on both MacOS and Linux. Since Windows have recently added the ability to run Linux in Windows, then all 3 operating systems are able to use a single package manager : Homebrew.
The purpose of this project is to be able to use this flexible package manager inside of an AmazonLinux image so that CI/CD systems and production servers on AWS can use the same practices as developers on their local machines.
To use the image locally:
docker pull nuagestudio/amazonlinuxbrew
Then:
docker run -it --rm nuagestudio/amazonlinuxbrew
The entry point of the image is bash, so to make sure brew works you can simply:
brew install wget
If you want to work on the project, you firstly need to install some dependencies.
They are listed in the Brewfile, which can simply be installed on MacOS:
brew bundle
The build system is based on Taskfile, which you need to install in order to run the build command:
task buildIf you don't want to work with the taskfile, you can simply docker build the Dockerfile directly.
The Homebrew package manager gets regularly updated, therefore in order to have an up-to-date Docker image we're using a trick by inserting a TIMESTAMP into the Dockerfile.
The CI is based on Github Actions, and is configured to run on the schedule : this way we keep most of the build in cache but simply update the Homebrew repository regularly.
If you work on the CI, you should start by having a look at build.yml
In order to avoid making a commit for every small change in the build file, you can use the act CLI at the root of the project.
By default, act doesn't have the docker CLI in its docker image, so we've built one specifically for that here
If you have Taskfile installed:
task ci
Otherwise:
act --platform ubuntu-latest=nuagestudio/github-actions:alpine
