Chainloop is under active development, please don't use it as part of your critical infrastructure until it reaches the 1.0 release.
The Chainloop Command Line Interface (CLI) comes pre-configured to use the Chainloop cloud control plane.
$ chainloop config view
But you can easily configure the CLI to point to your own Chainloop instance by using the
config save command.
chainloop config save --control-plane my-controlplane.acme.com --artifact-cas cas.acme.com
If you prefer to run your own instance, you can find the instructions to do so in the project repository.
