Hi Team! 👋 Is it possible to have a custom docker image in your local file system be referenced by the docker-container infrastructure block when building a deployment or am I required to have my custom docker image on Docker Hub/Docker Registry and access it through those systems?

yes it is, you would need to set the image pull policy to Never, then Prefect will only look for images available locally

@Anna Geller How can I pass the '-p {host_port}:{container_port}' option to the docker infrastructure block to properly map ports? When I try to connect to a external/remote mysql server instance from my code, I receive error '2002, can't connect to mysql server {my_server}, 115' when running the deployment. I think this is because my container doesn't have the properly mapped ports to connect to an external/remote mysql server. None of the documentation mentions how to pass the -p port argument

what's your setup? are you on Prefect Cloud or self-hosting? if you're self-hosting or just exploring things locally with docker, check out this docker compose setup https://discourse.prefect.io/t/running-prefect-2-with-docker-compose/1516

@Anna Geller We are using Prefect Cloud, is it possible to pass that -p in the docker container infrastructure block or is there another way we could map ports for the container?
This works great, thank you Anna! 🥂
