At my company we use Gitlab CI that's backed by a kubernetes cluster. I believe

docker build

wont be able to build in this environment (we use kaniko). Doe pants have a way of building stuff without docker build or is it just incompatible with kubernetes? If it's the latter, is there a plan to be able to build on kubernetes and if so how close is that to fruition?

Does not currently work. There are a couple issues on this topic, but none with progress that I’m aware of.

Thanks.

There was a docker less docker build in pants v1 I'm told

I've got a very early backend for OCI images here: https://tgolsson.github.io/pants-backends/oci-readme.html. It's only covering my own use-cases so far, which is one pex or binary -> OCI image -> kubernetes. Focus is on reproducible builds and stable SHAs. It should work OOTB for rootless (and obviously docker-less) builds. It's of course a big change in how you work if you're Dockerfile-based - but it's there if you want to try it.

Yeah, I wrote a series of tasks for pants V1 to build OCI images directly without the use of docker. I’ve been thinking about porting it to V2. It starts with defining a base docker image in your BUILD file, and then pants builds one layer per pants task/rule.

Why not depend on one of the existing tools like Buildah or Kaniko or etc. instead of rolling your own?

I can't speak for Tansy's implementation, but mine is a wrapper around Umoci 🙂

I wrote mine in… 2017? And I was unaware of any alternative tooling at the time
