Orion: Running flows in Docker results in an error
Description
I ran into an error when I tried to run the example flow in Docker. The flow:
from prefect import flow
from prefect.deployments import DeploymentSpec
from prefect.flow_runners import DockerFlowRunner
@flow
def my_flow():
print("Hello from Docker!")
DeploymentSpec(
name="example",
flow=my_flow,
flow_runner=DockerFlowRunner()
)
the error I received after creating deployment, work queue and an agent:
prefect agent start '5d76cc30-165e-4086-af9e-5fec6b4d7614'

Reproduction / Example
prefect orion start

prefect work-queue create -d <DEPLOYMENT-ID> test
prefect agent start <WORK-QUEUE-ID>
Hi! Thanks for the well written issue.
We're tracking an update to the tutorial internally at https://github.com/PrefectHQ/orion/issues/1123 This is similar to https://github.com/PrefectHQ/prefect/issues/4963 and https://github.com/PrefectHQ/prefect/pull/5182
The issue here is that the requests from the container being denied because the API is bound to 127.0.0.1 instead of 0.0.0.0. If you run prefect orion start --host 0.0.0.0, the container will be able to reach the API. This is a difference in container networking on Linux (this is not an issue on macOS).
We solved this in V1 of Prefect by including the container in a shared network with the server, but the server is not running in a container right now so we cannot apply the same fix. I'm not sure what the long-term solution is, it'd be nice to be able to use it without exposing your API via 0.0.0.0.
I believe you can also bind the Docker host IP 172.17.0.1 and it will allow connections from containers but won't allow connections from other sources.
@madkinsz im following the tutorial, running the orion server as you mentioned with prefect orion start --host 0.0.0.0
But im still getting the error

Is there any updates to this issue? Im testing implementing Prefect at my company but if this simple tutorial doesnt work, It makes me doubt of the stability of the project. The issue you reference does not exist (or is a private repo)
@manugarri Can you please share the output of prefect version? It'd also be great to see a docker inspect of the failed container.
Of course!, the version is 2.6.1 , here is the verbose output:
$ prefect version
Version: 2.6.1
API version: 0.8.2
Python version: 3.9.12
Git commit: d9dd4443
Built: Fri, Oct 14, 2022 2:01 PM
OS/Arch: linux/x86_64
Profile: local
Server type: hosted
Great thanks! @tpdorsey has the tutorial been tested on Linux or just macOS?
@manugarri if you can include the details about the container that'd great. Specifically, I'm interested in whether or not it is using a host network mode.
@madkinsz not sure how to check that, im just running prefect tutorial, and set up the infrastructure block as defined in the tutorial
im running this on my local machine, which is running ubuntu under WSL2 ,with docker studio.
I dont think the container gets to be built before the agent throwing the exception. Running docker -ps shows no prefect container running. I do see the prefect image so at least the build process started somehow.
@madkinsz I have not tested the tutorial in a Linux environment nor has it been tested under Ubuntu running in WSL2, which is a different case.
@manugarri Do you see the container with docker container ls --all? I do not believe ps will show stopped containers
@madkinsz you are right! I see the container , here is the output
Here is the output of docker inspect:

Great thanks! Here it looks like we are correctly setting the network mode and host gateway
"NetworkMode": "host",
...
"ExtraHosts": [
"host.docker.internal:host-gateway"
],
so it should be able to communicate with your API on locahost. Can you also share the output of docker version? Perhaps the requirements for networking on Linux have changed or you are on a version that does not support the "host" network.
Sure!

That version looks good, I'm pretty confused as we test containers on Linux in CI.
Would you try setting network_mode to "bridge" in your Docker infrastructure block?
Thanks for your patience!
By default, we use the "host" network mode on Linux when we detect that you're running an API on localhost because it makes it easier for users to get started. In this mode, your container can access anything on the network outside the container. Because of this, we do not change your API URL, it should just work. It looks like something's gone wrong with that, but we haven't gotten other reports of it and it's working fine in our tests so it'll take some investigation to determine what.
If you use the "bridge" network mode, the container is isolated and cannot talk to localhost. When we detect use of "bridge" with a local API, we need to convert your API URL to use "host.docker.internal" which lets it communicate outside of the container. This is a little more complicated, so we don't do it by default when the "host" mode is available.
