I am running a Docker container based on Alpine Linux 3. When I recently did my regular update, I found out that my Dockerfile doesn't work anymore because dcc fails to install properly.

Key elements in my Dockerfile that works under Alpine 3.19:

RUN apk add dcc dcc-dccifd

My entrypoint.sh contains:

if [ ! -f /var/dcc/dcc_conf ]
then
        echo "Error: no dcc configuration!"
        exit 1
else
        # alpine:
        /var/dcc/libexec/dccifd
fi

This fails under 3.20 and 3 latest

Investigating, I found out that under 3.20 and up, apk fails to fully install dcc. E.g. there is no /var/dcc/dcc_conf and /var/dcc/libexec/dccifd is now /usr/libexec/dccifd. That last one I could fix, but I do not trust the apk installation of dcc on these newer Alpine versions (who knows what else is missing?) Am I wrong and is there something else I need to do? Or is indeed the dcc apk package broken?

Do you mean 3.21 or 3.20? I can find a related change but it is only
included in 3.21: https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/74592

You are quite right. As of 3.21 it doesn't work (3.20 had another issue in my container, unrelated)

Basically, under 3.21 /var/dcc is empty except for a log directory. There is dcc_conf anywhere on the image (or whatever else is missing)

Seems the package is intermittently failing to build correctly.

v3.21 did not run make-dcc_conf:
https://build.alpinelinux.org/buildlogs/build-3-21-x86_64/community/dcc/dcc-2.3.169-r1.log
edge did: https://build.alpinelinux.org/buildlogs/build-edge-x86_64/community/dcc/dcc-2.3.169-r1.log

I'm guessing the Makefiles don't handle parallel builds very well,
I'll see if I can reproduce building locally.

Yes, the issue was related to parallel builds.

I opened a MR to fix the issue: https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/77234

Otherwise the move of files from /var/dcc/libexec/ to /usr/libexec/ was
intentional. So if you upgrade to 3.21 you should update the paths in the
entrypoint.sh.

Sure. But as long as dcc won't install I'm stuck at 3.20 (which is not a big problem of course)
