... ash scripts to install common devops tools with as minimal a footprint as possible ...

build-scripts-alpine

What?

Self contained scripts that should run under the default sh on Alpine, ash.

Each script is intended to install something taking up as little room on disk as possible.

Why?

Alpine is tiny. Seems a shame to bloat it up unnecessarily with lazy installs of other software.

How?

The scripts generally delete all unneeded files and avoid file-system caches for package managers etc.

... Docker

For creating containers using alpine as a base, these scripts will do stuff without polluting your Dockerfile or equivalent with lots of commands.

This keeps your Dockerfile readable but also allows for more complex logic during the build process inside your scripts without the creation of disk-consuming additional image layers.

Example Dockerfile
