Hi all,

prefect deployment build flows/hello.py:hello --name docker-custom --tag dev -sb s3/dev -ib docker-container/docker-custom-image

how do I expose the Port`8787` on docker-custom-image. I have configured volumes, networks on Docker Container block but didn't find any option about ports. I want to access Dask dashboard when I run flows from UI which spin up a separate container of my docker-custom-image.

why would you need to expose a port on the flow run container? not sure I understand -- you would need to do it the other way around, expose the port on your Dask container to see the Dask UI locally

@Anna Geller to my understanding, when I run a flow from UI it launches a seoarate docker container based on the

docker-custom-image

. temproary lacal dask cluster is launched inside the container by default.

And where is Dask?

I think what Faheem wants might be something like this:

docker container run -p 8787:8787

so that he can access the UI outside of the container

@Anna Geller thanks for ur reply @Khuyen Tran exactly,

@flow(task_runner=DaskTaskRunner())

this flow will run by default temporary dask cluster inside the docker container which is started by the flow from UI so I can't expose the port.
