provide crossplane composition for a constellation cluster setup

[hpvd]

Use case

more and more people adapt Crossplane to setup and manage "everything" resp. make the specialized knowledge of how to set up the needed resources in a simplified way available to every one who could benefit from this.

=> Would be pretty handy to have a Crossplane composition to setup - not only a standard kubernetes cluster in any cloud- but also a confidential one based on constellation (in the clouds with supported hardware)

her is just a quick video on what is possible this way:

and the doc to compositions:

Hi, thanks for trying out Constellation and for the feature request. We've heard about companies using Crossplane multiple times and have added it to our backlog, but this is quite low priority for now.

We are currently moving in the direction of integrating with Terraform/OpenTofu via a Terraform provider. It looks like that you could then integrate this into Crossplane with https://marketplace.upbound.io/providers/upbound/provider-terraform/v0.11.0.
Do you think that this would be a sufficient solution for you?

Hi, thanks for getting back that fast.
Good to hear it's already on your backlog ;-)
We have somehow fallen in love with the Crossplane approach (use Kubernetes to manage stuff including Kubernetes) plus cuelang->yaml and think it's a good way to go.
Of course, if it's not easily possible to "go native" with it, we will check the workarounds...

If you are interested in, this blog post compares terraform and Crossplane. Even if it's a little advertorial and already 2 years old, but the main points remain: https://blog.crossplane.io/crossplane-vs-terraform/

This is a more independent and up-to-date comparison:

maybe this summary in form of "Crossplane Graduation Proposal" for CNCF is of interest regarding

• its current growth and
• ongoing adaption in industries

and with it, the possibilities of being a visible part in its ecosystem..
