Hi all, I’m having some issues building + registering my flows via Jenkins. I am using

prefect build …

to first build the flow and output a

flow.json

to then use in my

register

command, but the build is failing. with the error message

docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

I believe this is a side effect of trying to build a docker image whilst running in a docker container, has anyone ever run into this issue?

Hey @Leon Kozlowski, not exactly the same but Docker in Docker can be a problem. Check this .

I can try this — Is there a best practice for building + registering flows in CI/CD pipeline?

I would honestly say no because there are so many different setups and it depends on the organization.
