shared

You can run QEMU/KVM using docker/podman. I made a simple container here for it that lets you use cloud-init: https://github.com/candiddev/shared/tree/main/containers/qem...

We needed an easy way to build and test VMs using QEMU for both development and CI/CD. Instead of reaching for something like KubeVirt, we built a really simple container to run VMs of various architectures.

You only looked at the pseudo version and missed the important replace directives replace github.com/candiddev/shared => ./shared replace github.com/google/go-jsonnet => github.com/thequailman/go-jsonnet v0.0.0-20230924031349-110b4ca1dc1a The replacement with ./shared means it's using exactly the version on disk (which is in a submodule here). The go-jsonnet replacement points to a specific commit.

That library you linked to is part of a shared repo we use for all of our stuff, https://github.com/candiddev/shared, it's versioned using git modules. We own all of the underlying code. We opted for git submodules because go modules hate CalVer, and we share a bunch of other stuff besides go libraries. In the end, things are versioned like any other Go program, builds are 100% reproducible.

Not really... - Start migration, create transaction and locks - Do migration things - Do some SELECTs, INSERTS, or w/e in your code to validate the schema matches your model. - End transaction or rollback if failure None of this is free, but it's by no means hard IMO. I do something similar in Go: https://github.com/candiddev/shared/blob/main/go/postgresql/...
