podshell

Simple and small container env for development and debug purposes.

By default, the container starts as a regular user, to play nice with potential Kubernetes admission policies. Therefor, the a set of most useful packages is already installed, while keeping an eye on the container image size. The package list is not exhaustive, but can be extended by using the binenv tool. Run binenv to install various packages, by running binenv update, binenv search and binenv install <pkg>.
