Always deploy from main for now. We want to keep testing commits to main
as soon as they're merged, so we're going to disable the release
freezing behavior. We will test cut releases on a separate deployment,
upgraded manually.
Relates to https://github.com/coder/dogfood/pull/189
Closes https://github.com/coder/internal/issues/1021
- Adds new script `scripts/should_deploy.sh` which implements the
algorithm in the linked issue
- Changes the `ci.yaml` workflow to run on release branches
- Moves the deployment steps out of `ci.yaml` into a new workflow
`deploy.yaml` for concurrency limiting purposes
- Changes the behavior of image tag pushing slightly:
- Versioned tags will no longer have a `main-` prefix
- `main` branch will still push the `main` and `latest` tags
- `release/x.y` branches will now push `release-x.y` tags
- The deploy job will exit early if `should_deploy.sh` returns false
- The deploy job will now retag whatever image it's about to deploy as
`dogfood`
