jetskis is a distrobox/toolbx container made to be used inside of a Fedora Silverblue (or derivative) environment.

If you use distrobox:

distrobox create -i ghcr.io/jitcos/jetskis -n jetskis
distrobox enter jetskis

If you use toolbx:

toolbox create -i ghcr.io/jitcos/jetskis -c jetskis
toolbox enter jetskis

These images are signed with sisgstore's cosign. You can verify the signature by downloading the cosign.pub key from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/jitcos/jetskis

If you're forking this repo you should read the docs on keeping secrets in github. You need to generate a new keypair with cosign. The public key can be in your public repo (your users need it to check the signatures), and you can paste the private key in Settings -> Secrets -> Actions.
