@Marvin when i build the docker image, do i need to set any environmet variables for connecting to prefect server? Mine is just runnign on local host 127.0.0.1:4200/api

To connect to a Prefect server from within a Docker container, you need to set the environment variable

PREFECT_API_URL

to point to your server's API URL. Here’s the relevant information: * Environment Variable:

PREFECT_API_URL

* Value:

<http://127.0.0.1:4200/api>

This environment variable must be set when running Prefect inside a Docker container because it ensures that the Prefect client communicates with the correct server address. Here is an example of setting this environment variable in a Dockerfile:

Dockerfile
ENV PREFECT_API_URL=<http://127.0.0.1:4200/api>

Alternatively, if you're running a Docker container, you can set the environment variable directly in your Docker run command:

bash
docker run -e PREFECT_API_URL=<http://127.0.0.1:4200/api> your_docker_image

For additional context and examples, you can refer to the Prefect documentation and related GitHub issues. Let me know if you need further assistance!

@Marvin is this the same for API_URL http://host.docker.internal:4200/api

Yes, the environment variable

PREFECT_API_URL

should be set whether you are using

<http://127.0.0.1:4200/api>

or

<http://host.docker.internal:4200/api>

. Both configurations are indeed related to the same concept of setting the API URL for Prefect to connect to the server, but within a Docker context: If you are running Docker on a macOS or Windows machine, Docker might map

host.docker.internal

to the host IP automatically. On Linux, you might need to add an additional host mapping using the

--add-host

flag in your Docker run command like this:

bash
docker run -e PREFECT_API_URL=<http://host.docker.internal:4200/api> --add-host=host.docker.internal:host-gateway your_docker_image

This helps the container resolve

host.docker.internal

to the correct gateway IP. For more details, you can refer to the official Prefect documentation. Let me know if there's anything else you need!
