But other than that it should be pretty good. The workflows require you to add a PAT with the packages scope from github and also a dockerhub username and password to the secrets for this repo.

It'll automatically build for multiarch (arm, x86, etc) and push to ghcr.io and dockerhub. I also added a docker-compose.yml for testing.

If you have any questions, a solution for the error above, or any requests to change this PR, feel free to let me know. Most of it was copied from https://github.com/selfhostedpro/yacht if you're curious about how any of this works that may give you some insight.

@skluthe is attempting to deploy a commit to the calendso Team on Vercel.

A member of the Team first needs to authorize it.

Didn't see #7 sorry about that! May be some useful stuff from this to copy over.

@skluthe ran into a similar issue, it looks like the postinstall https://github.com/calendso/calendso/blob/main/package.json#L9 script isn't running. I had to run yarn postinstall manually before the primsa command in order for it to run

Going to close this PR as we're not officially supporting Docker. We may reconsider supporting it in future. Thanks very much for your help though!

docker support now exists here: https://github.com/calendso/calendso-docker powered by the community. not officially maintained by the calendso core team, yet.
