Suppose I have a flow. In the flow, I want to run a task which is delivered to me as a container. Is there an easy way to have a task simply be “run this container with these arguments”, analogous to `docker run --rm --mount type=bind,source=$SRC,target=$DEST -it thing:label arg1 arg2 …`? My gut feeling is that the `DockerContainer` block should support this but I’m getting a feeling it is for another purpose than this, since I don’t see how to pass the arguments or mess around with the mounts

hi <@U05H5NCDW3U> - you should be able to use `DockerContainer` for this
```In [6]: from prefect.infrastructure.container import DockerContainer
   ...:
   ...: DockerContainer(
   ...:     image="alpine:latest",
   ...:     command=["echo", "Arguments received:", "arg1", "arg2"]
   ...: ).run()

<@U02GMEZU18B> I’m following your guide above, but when I run the DockerContainer as per below it fails with : 404 Client Error for <http+docker://localhost/v1.41/images/create?tag=latest&fromImage=merge>: Not Found (“pull access denied for merge, repository does not exist or may require ‘docker login’: denied: requested access to the resource is denied”)

from prefect.infrastructure.container import DockerContainer

DockerContainer(
    image=“merge”,
    command=[“python”, “/app/modules/merge/scripts/run_test_script.py”]
).run()

But I can get the corresponding docker bash line to run
docker run --entrypoint python merge /app/modules/merge/scripts/run_test_script.py

So how do I setup the DockerContainer to ‘connect’ to my local docker? Are there permissions I need to set? I’ve not installed a Block in the server as that looks like it relates to remote docker instances.

Any ideas?
