Hello, has anyone run a separate docker image in a flow? My prefect deployment goes as:

prefect deployment build fx_run.py:fx_rates_flow -n fx_deploy --infra docker-container -sb remote-file-system/minio

and then I also created a custom docker image with s3fs installed which I pull during deployment. However I keep getting the error:

No such file or directory: 'docker': 'docker'

. Can anyone advise?

Can you use S3 instead of minio? Otherwise you may solve it by switching to process infra e.g. --infra process

Thanks for the help. Running it as a local Process requires s3fs to be installed. Is that not required for s3 anymore and already baked into the offical image? Declaring additional EXTRA_PIP_PACKAGES in the env field, won't work as our company cluster is shielded by proxies. If I add those too, the flow isn't executed which I noticed a couple of time, i.e. when I created a separate docker agent in a Dockerfile I had to declare the http_proxy, etc first, install packages and remove the env vars again. I am not sure what is happening under the hood...

yup exactly, no s3fs required when flow code is baked into the image
