Summary
Enable Docker layer cache for the
ib/deploy/service-gcpCI job.The job currently runs without cache (
cache.image: falseby default), causing it to re-download ~250MB of external dependencies on every build:dep ensure(6 min)All of these are pure environment layers unrelated to source code. With
cache.image: true, Docker will reuse these layers across builds. TheCOPY . /go/src/...step still invalidates cache on any code change, so the latest code always enters the image correctly.
