- Update to windows RBE docker image, followed by subsequent regenerate
of win RBE toolchain (basically verifying that the README.md for windows
RBE toolchain works well)
- Also move windows docker image from GCR to GAR (which is where our
other testing images already live).
- (cleanup) Move windows RBE docker image to a better location in our
repo.
This PR should be sufficient to demonstrate how we would go about
upgrading the windows RBE build to VS2022 once needed.
- Upgrade windows RBE builds to bazel 6.3.2 (supersedes
https://github.com/grpc/grpc/pull/33880). To be able to do that, the RBE
toolchain needed to be regenerated and
- Also added "--dynamic_mode=off" option for windows build since it
seemed necessary for bazel 6.x builds to pass.
- Wrote instructions for generating windows RBE toolchain using the
`rbe_configs_gen` tool (the original windows RBE toolchain was out of
data and also it was generated by a custom script from
go/rbe-windows-user-guide - using a standard tool is better)
- Wrote instructions for rebuilding the windows RBE docker image.
This addresses the problem where windows RBE is stuck on bazel 5.x
(unlike the rest of the repository) and also documents the steps for
making changes to the RBE docker image (e.g. upgrading the visual studio
version used by RBE).
Since we were planning on adding testing for VS2022 (for which we don't
have any test ATM), this will definitely come handy. With the
documentation the process should now be relatively straightforward.
- Remove no-longer-needed workaround for b/275571385 (and switch back to
using docker image from GAR)
- regenerate RBE linux toolchain for bazel 6.1.2 while at it.
- Add a new docker image "rbe_ubuntu2004" that is built in a way that's
analogous to how our other testing docker images are built (this gives
us control over what exactly is contained in the docker image and
ability to fine-tune our RBE configuration)
- Switch RBE on linux to the new image (which gives us ubuntu20.04-based
builds)
For some reason, RBE seems to have trouble pulling the docker image from
Google Artifact Registry (GAR), which is where our public testing images
normally live, so for now, I used a workaround and I upload a copy of
the rbe_ubuntu2004 docker image to GCR as well, and that makes RBE works
just fine (see comment in the `renerate_linux_rbe_configs.sh` script).
More followup items (config cleanup, getting local sanitizer builds
working etc.) are in go/grpc-rbe-tech-debt-2023
First step in the modernization of our RBE stack (see
go/rbe-tech-debt-notes).
- Get rid of the deprecated rbe_autoconfig and start using
[rbe_configs_gen](https://github.com/bazelbuild/bazel-toolchains#rbe_configs_gen---cli-tool-to-generate-configs)
+ check in the generated toolchain configs.
- Switch from marketplace.gcr.io/google/rbe-ubuntu16-04 to
marketplace.gcr.io/google/rbe-ubuntu18-04 (this image is still not owned
by us, but at least it's newer and demonstrates how a switch to a newer
docker image is done).
- provide script for generating the linux RBE toolchain configs.
- cleanup RBE configuration in the bazelrc files used for remote build
