Prefect Community

After building Docker storage using a custom local Dockerfile for multiple flows a la <https://docs.prefect.io/cloud/recipes/multi_flow_storage.html#adding-flows-to-storage>

is it possible to execute a flow in situ locally, running in the container, to closely replicate remote execution?

Do you want to run the flow in the context of a cloud run or a local run inside the container to see if it works?

More clearly: do you want the flow to communicate state with Prefect Cloud for this run or no?

This would be a local run but executing the `/root/.prefect/my_flow.prefect`  within the container to see if it works.

In that context, would it still need to connect to Prefect Cloud to get secrets, or would the

```[cloud]
use_local_secrets = true```
and all the configs in my `~/.prefect/config.toml` be honored during this local run?

If the `config.toml` inside the container contains your secrets then setting `use_local_secrets` to True would use them otherwise it should be fine grabbing the secrets from cloud if set to false. To run your flow inside that container do something like:

```from prefect.environments.storage import Docker

flow = Docker().get_flow(flow_location="/root/.prefect/my_flow.prefect")

flow.run()```

```Traceback (most recent call last):
  File "./workflows.py", line 221, in &lt;module&gt;
    main()
  File "./workflows.py", line 207, in main
    flow_location=f'/root/.prefect/{flow.name}.prefect'
  File "/home/luke/.pyenv/versions/kepler/lib/python3.7/site-packages/prefect/environments/storage/docker.py", line 214, in get_flow
    with open(flow_location, "rb") as f:
PermissionError: [Errno 13] Permission denied: '/root/.prefect/my_flow.prefect'```

How are you running the docker container? `docker run -it my_image`? Looks like in the image you build you don’t have root access

ah, I was assuming that since flow came from the Docker().get_flow,  `flow.run()` would run `docker run -it ...` for you. I ran that and stopped getting the PermissionError. Now it seems to be failing to find a variable I added to my local prefect config. I'm not copying a `config.toml` into the container, so looks like I'll need to figure that out. Thanks for the guidance!
