Has anyone had any issues running a docker agent on a linux server?

I’m getting a bunch of
```requests.exceptions.ConnectionError: HTTPConnectionPool(host='host.docker.internal', port=4200): Max retries exceeded with url: /graphql/alpha (Caused by NewConnectionError('&lt;urllib3.connection.HTTPConnection object at 0x7fa1de7c7450&gt;: Failed to establish a new connection: [Errno -2] Name or service not known'))```
from the docker agent when trying to run a flow

I’m not sure if I’ve misconfigured something, but it looks like it also _could_ be related to <https://github.com/docker/for-linux/issues/264>, but not entirely sure.

Hey <@ULQLBDKSP> looks like Docker for Linux is having trouble connecting out to the host machine, another discussion happening here <https://prefect-community.slack.com/archives/CL09KU1K7/p1586101754445600>

Yeah it’s definitely related to the `host.docker.internal` which looks to have been implemented for Linux users however it appears that it has not been released yet. This means we’ll need to find another workaround :slightly_smiling_face:

Awesome. Thanks for the quick follow up Josh

We run in docker / docker-compose fine, tho via `pip install` .  (We do that so we can reuse our pydata base env across our project.)

<@U010D3M5ACA> just to confirm, you’re seeing success running the docker agent on a linux server?
