Cannot run snapcraft in docker anymore #5079

om26er · 2024-09-30T15:10:08Z

Bug Description

I cannot run snapcraft in docker container anymore. It requires snapd to be running.

To Reproduce

Build a docker container with snapcraft in it and then use that docker container to build a snap

Environment

Docker with noble based image

snapcraft.yaml

no yaml config needed

Relevant log output

root@d04e7a25f671:/datax# SNAP_INSTANCE_NAME=snapcraft snapcraft version

Thanks for the report! The only way I could see this happening is if you're setting the SNAP environment variable and the rest of the environment to mimic running in a snap. Could you try unsetting the SNAP environment variable in your container and see if it succeeds?

Separately I've created canonical/craft-application#497 upstream so that we behave better in situations like this.

lengau · 2024-09-30T18:02:33Z

Separately from this - would it be feasible to move your use of snapcraft in containers to use https://github.com/canonical/snapcraft-rocks?

josephtensoriot · 2024-10-01T15:38:08Z

I am running into the same issue.

First, I saw an error stating

snapcraft internal error: AttributeError("'INSTANCE_NAME'")

After adding the SNAP_INSTANCE_NAME env var, which wasn't required when running Snapcraft 8.3.4, it then gave me the socket error mentioned above. Removing the SNAP variable resulted in another error:

/usr/bin/python3: can't open file '/bin/snapcraft': [Errno 2] No such file or directory.

Oddly enough, this actually only happens for the snapcraft upload and snapcraft version command. I am able to run snapcraft and snapcraft release without seeing the INSTANCE_NAME error.

om26er · 2024-10-02T11:47:14Z

@lengau I used docker container from https://github.com/canonical/snapcraft-rocks and the build almost worked but it failed when my override-build stanza tried to call craftctl to set version.

This will be fixed in Snapcraft 8.4.2, which is scheduled to be in the candidate channel next week.

Hi @josephtensoriot,

Sorry about this error occurring again.

After adding the SNAP_INSTANCE_NAME env var, which wasn't required when running Snapcraft 8.3.4, it then gave me the socket error mentioned above.

Can you remove this environment variable and try again?

you should remove these three lines

ENV SNAP=/snap/snapcraft/current
ENV SNAP_NAME=snapcraft
ENV SNAP_INSTANCE_NAME=snapcraft

ENV SNAP_INSTANCE_NAME=snapcraft

Removing SNAP gives me: /usr/bin/python3: can't open file '/bin/snapcraft': [Errno 2] No such file or directory and the SNAP_INSTANCE_NAME gives me an emitter issue I posted in the previous response. I don't think I can get around removing either of those two. SNAP_NAME might be fine to remove though from what I've seen in my testing locally.

@josephtensoriot you should look at my complete Dockerfile I posted above. Note how I create the snapcraft launcher

Seems there was one line I missed that was different:
RUN echo 'exec "$SNAP/usr/bin/python3" "$SNAP/bin/snapcraft" "$@"' >> /snap/bin/snapcraft
needed to be changed to
RUN echo 'exec "/snap/snapcraft/current/bin/python3" -m snapcraft "$@"' >> /snap/bin/snapcraft
That was the missing link and did the trick for me. Thanks!

Glad it's working. I'm going to leave this issue open because we can improve the error handling.
