Remote Build Caching for Container Builds
Container image builds get slower as a Dockerfile grows, and CI runners rarely keep a warm
local cache between runs. Teams work around this with a handful of docker/setup-buildx-action
and docker/build-push-action steps that provision a builder and wire up a remote cache — glue
that lives outside the rest of the pipeline and has to be reproduced in every workflow that builds
an image.
The native container build step can now provision that builder and cache directly, so a build's
caching strategy lives next to the rest of its configuration instead of in separate Actions.
