10/01/2025, 10:25 PMQuestion on pants remote execution setup with BuildBarn. We have a working BB setup on K8 cluster, which works with Bazel. I am trying to get it to work with pants. In `pnats.toml`:
Copy code
remote_cache_read = true
remote_cache_write = true
remote_store_address = "grpc://<an IP address>:8980"
remote_execution_address = "<grpc://an> IP address:8980"
remote_execution = true
remote_instance_name = "fuse"
remote_execution_extra_platform_properties = [
"OSFamily=linux",
"container-image=<docker://ghcr.io/catthehacker/ubuntu:act-22.04@sha256:5f9c35c25db1d51a8ddaae5c0ba8d3c163c5e9a4a6cc97acd409ac7eae239448>",
] Copy code
IntrinsicError: For action Digest { hash: Fingerprint<5906949aad5aadf90f4abaf085563563b18037233bab5287de902e0909cccfbc>, size_bytes: 139 }: No workers exist for instance name prefix "fuse" platform {}platformh

10/07/2025, 7:30 PMyes, I did experiment with that:
Copy code
remote_environment(
name="my_remote_env",
#platform="ubuntu-act-22-04-platform",
platform="linux_x86_64",
extra_platform_properties = [
"docker-container=<docker://ghcr.io/catthehacker/ubuntu:act-22.04@sha256:5f9c35c25db1d51a8ddaae5c0ba8d3c163c5e9a4a6cc97acd409ac7eae239448>",
"OSFamily=linux",
"container-image=<docker://ghcr.io/catthehacker/ubuntu:act-22.04@sha256:5f9c35c25db1d51a8ddaae5c0ba8d3c163c5e9a4a6cc97acd409ac7eae239448>",
],

10/07/2025, 7:37 PMThe weird thing the response indicated the platform specification in the request was empty but when I specify it to something invalid (like the comment out value) then it complains:
Copy code
InvalidTargetException: BUILD:24: Values for the 'platform' field in target //:remote must be one of ['linux_arm64', 'linux_x86_64', 'macos_arm64', 'macos_x86_64'], but 'ubuntu-act-22-04-platform' was providedh

10/09/2025, 3:37 AMWell, that's just validation of the target field, which happens long before any requests are actually made

10/09/2025, 3:37 AMI know some folks have made BB work, have you searched this Slack for any prior art?
