Hi Prefect community! We’re currently running the prefect server, prefect docker agent with a local docker image and I’m using Docker storage which points at my local Dockerfile. That works fine, but switching the backend from server to cloud somehow doesn’t. We have Prefect Cloud seats and I’ve successfully authenticated my agent, and I’ve successfully registered my flows. When I try to run a flow using the Prefect Cloud UI, my prefect docker agent console says

Deploying flow run...

but the flow gets stuck in the

Submitted

stage. What am I missing?

Hi Fina! Usually runs stuck in submitted states are caused by the image either failing to get pulled or failing to initialize properly, but your agent should detect those situations and either fail the run or create a log. A few questions: • can you see a container ID referenced in the logs? If so can you see if that container produced any logs or issues? • Is your agent running a recent version of prefect? • if you restart your agent with the —verbose flag and place the run back in a scheduled state do you notice anything?

Thank you for your help @Chris White! Yes the prefect cloud dashboard shows me a container ID in the logs section:

Submitted for execution: Container ID: 92c(...)

But when I check my local containers by running

docker ps

it doesn’t show anything! (It does show containers as expected when I run things with the prefect server instead of prefect cloud) I’m currently using prefect

0.14.5

. The agent doesn’t seem to have a

-verbose

flag(?) What am I missing?

Hm very interesting;

prefect agent start --verbose

should be a documented / exposed CLI flag — would you mind opening a GitHub issue with the details so we can investigate further?

@Chris White I think I had misunderstood: Since I’m using local Docker Storage and the Docker Agent the command I use to run the agent is

prefect agent docker start

. That command doesn’t have a verbose flag. However

prefect agent start --verbose

does exist, but that agent throws an error if I try to use it with my setup, and that error makes sense:

Error while deploying flow: TypeError('Unsupported Storage type: Docker')

. Should I open a github issue to request the verbose flag for the docker agent? Besides that, the problem still seems to be that the container doesn’t exist, even though I get provided with a container ID. What are the best next steps?

Ahhh nice!! Glad you figured it out 😄
