Sandbox for Testing Packages

A one-off disposable environment to test packages for the latest ubuntu release of our SW distros.

To get started, simply click on the badge below:

Important

You need to enable the Codespaces feature on your account to access the sandbox.

Instead, if you aim to test against different distros/releases, do:

1. 📝 Edit the file Dockerfile and create a new branch. In detail, you have to fiddle with these sections.
2. 🚀 Launch the corresponding GitHub Codespace from within the new branch. Don't click on the main badge but rather use the green <> Code button up here (switch to the tab Codespaces).
3. 🧹 Finish up by wiping out the branch.

⚠ How to flush the docker cache

As Docker relies on cached sections, you may still be using an old image when you've just updated a package to test. To invalidate the cache forcing Docker to build the relevant sections entirely again, apply the following workarounds:

• If you aim to build the whole image again, increase the variable INVALIDATE_DOCKER_CACHE_ALL.
• If you've just fixed up the packages and aim to download and install them again, increase the variable INVALIDATE_DOCKER_CACHE_DL.
