The "Set up Buildx" step in build-main.yaml ran without DOCKER_CONFIG, so docker/setup-buildx-action created the docker-container builder under the default ~/.docker. The build step runs with DOCKER_CONFIG=$RUNNER_TEMP/.docker (seeded before the builder existed and holding the OCIR auth), so it could not find the builder and failed immediately with `no builder "builder-<uuid>" found`. The post-job `docker buildx rm` still succeeded because the action's cleanup runs under the default config where the builder actually lived. Set DOCKER_CONFIG on the Set up Buildx step so the builder instance is created in the same config the build step reads.

# Warms the shared mode=max build cache so PR builds start hot.
|
|
#
|
|
# PR builds (pull-requests.yaml) read the cache but never write it
|
|
# (WRITE_CACHE unset -> 0). Only this serialized main build writes
|
|
# CACHE_REGISTRY/<img>:buildcache, so concurrent PR builds never race on the
|
|
# cache manifest -- the 409 collisions PR #2711 fixed for image tags would
|
|
# otherwise reappear on the cache ref. Cache is mode=max so all multistage
|
|
# `builder` stages are cached, not just the final stage as with inline.
|
|
#
|
|
# This job builds on a docker-container buildx builder, NOT the host's default
|
|
# embedded `docker` driver: `--cache-to type=registry,mode=max` is unsupported
|
|
# on the docker driver unless the daemon runs the containerd image store, so on
|
|
# a classic store the warmer would otherwise fail to export any cache. The
|
|
# container driver also gives this build its own buildkit (separate bbolt), so
|
|
# the warmer never contends with PR builds on the shared embedded buildkit.
