Docker error in the pipeline

I’m trying to get this example running in my pipeline but I kept getting this Docker error:

Running with gitlab-runner 15.4.0 (43b2dc3d)
on SEITaaS HPDxKxWy
Preparing the “docker” executor

ERROR: Failed to remove network for build

Any idea? I provided the link above to the project.

Appreciate any help!

If this is not the right forum, please suggest the alternative.

Thanks,

Hi,

The example project specifically says it works with shell executor. From the job output your GitLab Runner is using docker executor, hence the error.
