I want to debug a failing
docker compose build --no-cache
(it succeeds with the cache), however due to the log limit, I cannot see the reason for the failure, only the message output clipped, log limit 1MiB reached
.
Following the Docker documentation, I created the following /etc/docker/daemon.json
:
{
"features": { "buildkit": true },
"log-driver": "local",
"log-opts":
{
"max-size": "100m",
"max-file": "3"
}
}
After systemctl docker restart
, docker info
shows:

Notably, the logging driver is now shown as "local", where before it was "json-file", so it seems to me as if Docker is successfully loading /etc/docker/daemon.json
.
However when I execute docker compose build --no-cache
again, I still get the message output clipped, log limit 1MiB reached
.
How do I get docker compose
to not ignore daemon.json
or is there any other way to access the full build log?
I am using Docker version 20.10.17, build 100c70180f, Docker Compose version 2.6.0 with BuildKit on Arch Linux with Kernel 5.18.5.
BuildKit cannot be deactivated because the build uses --mount=type=cache,target=/root/.m2
to cache Maven dependencies.
