        there's no UI for it yet but the playbooks will run fine on a local host if you skip cloud.yml. Join the Slack if you have issues.

        raccoon doesn't support IKEv2, raccoon2 is not actively developed. I used StrongSwan, not OpenSwan, bc it went through a rewrite.

        just a thought wouldn't something like alpine linux provide a smaller attack surface than Ubuntu and be perfect for this use case?

        that would be great, but name a cloud provider that supports it out of the box.
