I'm running into some more weirdness with using the docker buildx builder from pants. When I try to use pants publish or try to do a multi-stage build, I run into this type of error:

An image does not exist locally with the tag: europe-west4-docker.pkg.dev/smart-shoreline-391915/espresso-docker/prod/prod

I have also seen this this warning:

WARNING: No output specified with docker-container driver. Build result will only remain in the build cache. To push result image into registry use --push or to load image into docker use --load

I have seen some docs imply that pants should be adding the --load argument when it does builds, e.g. https://docs.openfn.org/articles/2021/10/08/improving-multistage-docker-builds-using-buildx#local-cache

we plan to pick this to 2.19 and also to 2.18.1, hopefully that will be done when the next 2.19 rc is released.

is there a timeline for rc releases, or just when it's ready?

you can read about our guide lines here: https://www.pantsbuild.org/docs/release-strategy basically we try to do releases once a week. rc releases may be longer (or shorter) in-between depending on what changes has gone into them.. so it’s not a very firm schedule, no.

Yeah, I read that doc but wasn't super clear on when main will get into a release next. Will there be a new 2.20 dev release at the end of the week if not an rc?

yea, so we had the first alpha for 2.19 last week, so this week we should see the first dev release for 2.20 (as well as another rc (or alpha) for 2.19)
