[pseudocomposer]

Various ways in various companies, but in my last few companies pretty much always “CI runs tests and builds/uploads a Docker image, CD deploys it onto a K8s cluster somewhere.”

In the case of my major current personal project, I do it with a GitHub Actions workflow: https://github.com/JonLatane/jonline/blob/main/.github/workf...

A deploy looks like this: https://github.com/JonLatane/jonline/actions/runs/1346474905...

Here, I do a canary deploy to a dev server (jonline.io), then cut a GitHub release and deploy to production servers (bullcity.social, oakcity.social). (All really live on the same single-box dinky K8s cluster.)
