Self-hosted Runner failing: An error occurred whilst creating container exec.

Question

Hi,

I'm having issues when starting builds on the self-hosted runner with the following `error: An error occurred whilst creating container exec.`.

I've attached the docker file and the log from the runner.

Thanks!

Docker-file

I had the same issue. Sadly, the runner does not log enough detail to diagnose this easily, BUT, I for me the issues was the WORKING_DIRECTORY being out of wack with the mounted volumes.

From your example

volumes:      - "/tmp:/volume1/docker/runner/tmp"    environment:      WORKING_DIRECTORY: "/tmp"All of these need to be the same. My mental model is, that the runner shares the working directory with it's child containers, and because it doesn't know what the mount points are, it expects WORKING_DIRECTORY is the same inside and outside the container. So, this should work:    volumes:      - "/volume1/docker/runner/tmp:/volume1/docker/runner/tmp"    environment:      WORKING_DIRECTORY: "/volume1/docker/runner/tmp"I'm doing something similar on GCP, using /mnt/disks/bitbucket where that is the mount point of my data disk.

I have the exact same issue.

I do not use a dockerfile in contrast to Jacky, I run command as

docker container run -it \
-v /tmp:/tmp \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /var/lib/docker/containers:/var/lib/docker/containers:ro \
-e ACCOUNT_UUID=redacted  \
-e RUNNER_UUID=redacted \
-e RUNTIME_PREREQUISITES_ENABLED=true \
-e OAUTH_CLIENT_ID=redacted \
-e OAUTH_CLIENT_SECRET=redacted \
-e WORKING_DIRECTORY=/tmp \
--name runner-redacted \
docker-public.packages.atlassian.com/sox/atlassian/bitbucket-pipelines-runner:1`

And logs shows

Sometimes it doesn't crash, but pipeline that trigged the build is stuck in "cloning". Pass beyond the runner version (current/running) there is nothing even after 30 minutes.

Hi,

Where is this dockerfile located? How did you run the self hosted runner from your pipeline?

If its something related to the runner, it makes sense to recreate it (delete in the settings and then re-run the container command).
