You can adjust output from this with the --progress option:
--progress string Set type of progress output (auto, plain, tty). Use plain to show container output
(default "auto")
Adding --progress=plain will show the output of the run commands that were not loaded from the cache. This can also be done by setting the BUILDKIT_PROGRESS
variable:
export BUILDKIT_PROGRESS=plain
If you are debugging a build, and the steps have already been cached, add --no-cache to your build to rerun the steps and redisplay the output:
docker build --progress=plain --no-cache ...
If you don't want to use buildkit, you can revert to the older build engine by exporting DOCKER_BUILDKIT=0 in your shell, e.g.:
DOCKER_BUILDKIT=0 docker build ...
or
export DOCKER_BUILDKIT=0
docker build ...
