Prefect Community

could someone point us in the right direction so that we can properly evaluate your solution?

Hey <@U06AMLUL8SZ>! It looks like you’ve taken all of the correct steps to start a Docker worker. Can you share some more about what you’re finding difficult?

We get an error, something that server cannot be used as worker… it’s not a very helpful error (I can paste the exact message when I get to the computer)

The error is `RuntimeError: Docker worker cannot be used with an ephemeral server.` <@U02GE39K551>

Any ideas?

Hey <@U06AMLUL8SZ>! Sounds like you are using a self-hosted Prefect server instance and not Prefect Cloud. If that’s your setup, you can run the following:
```prefect config set PREFECT_API_URL="<http://127.0.0.1:4200/api>"```
More details <https://docs.prefect.io/latest/guides/host/#configuring-a-prefect-server-instance|here>.

In addition to <@U03KWSKFN8L>’s suggestion, you can run `prefect server start` to run an instance of the Prefect server API locally which your worker will be able to communicate with.
