I’m trying to implement tests for my cwl code in bitbucket pipelines. Therefore I need to run the cwl code using:

`cwltool main.cwl inputs.yml`

Although this works locally, if you run this in the bitbucket pipeline you get the following error:

`docker: Error response from daemon: authorization denied by plugin pipelines: --mounts is not allowed.`

I’ve tried the `--udocker` option but that would increase my run time considerably, which is why I would prefer another option.

Is there a way to avoid using the `--mounts` option to be able to run cwltool in the bitbucket pipeline?

Hello @tjvneste and welcome!

In `cwltool`, `--mounts` is required for use of docker. I’m surprised that bitbucket is allowing docker at all if they don’t allow `--mounts`, that is a very normal need for most users.

If you can satisfy the software dependencies another way, you can try running your workflow with `cwltool --no-container`.
