I m trying to setup Prefect using the following

Question

I m trying to setup Prefect using the following <https github com fraibacas prefect orion blob main docker compose yaml|docker compose> Everything seems to work except one important thing being able to run a flow which I ve deployed with a DockerContainer infrastructure block and Github as storage block Traceback from the agent I ve removed the url in the second line ```18 41 58 602 | INFO | prefect agent Submitting flow run 5b4470d3 8cd0 4073 8c03 be70eac1deff 18 41 59 077 | INFO | prefect infrastructure docker container Pulling image URL 18 41 59 722 | INFO | prefect infrastructure docker container Creating Docker container invaluable hyena 18 41 59 743 | INFO | prefect infrastructure docker container Docker container invaluable hyena has status created 18 42 00 303 | INFO | prefect agent Completed submission of flow run 5b4470d3 8cd0 4073 8c03 be70eac1deff 18 42 00 307 | INFO | prefect infrastructure docker container Docker container invaluable hyena has status running 18 42 02 695 | INFO | prefect infrastructure docker container Docker container invaluable hyena has status exited 18 42 02 697 | INFO | prefect infrastructure docker container Docker container invaluable hyena has status exited ``` Traceback from the container ```Flow could not be retrieved from deployment Traceback most recent call last File usr local lib python3 8 site packages prefect engine py line 260 in retrieve flow then begin flow run flow = await load flow from flow run flow run client=client File usr local lib python3 8 site packages prefect client utilities py line 47 in with injected client return await fn args kwargs File usr local lib python3 8 site packages prefect deployments py line 167 in load flow from flow run await storage block get directory from path=deployment path local path= File usr local lib python3 8 site packages prefect filesystems py line 908 in get directory process = await run process cmd stream output= out stream err stream File usr local lib python3 8 site packages prefect utilities processutils py line 73 in run process async with open process File usr local lib python3 8 contextlib py line 171 in aenter return await self gen anext File usr local lib python3 8 site packages prefect utilities processutils py line 35 in open process process = await anyio open process command kwargs File usr local lib python3 8 site packages anyio core subprocesses py line 127 in open process return await get asynclib open process File usr local lib python3 8 site packages anyio backends asyncio py line 1105 in open process process = await asyncio create subprocess exec File usr local lib python3 8 asyncio subprocess py line 236 in create subprocess exec transport protocol = await loop subprocess exec File usr local lib python3 8 asyncio base events py line 1630 in subprocess exec transport = await self make subprocess transport File usr local lib python3 8 asyncio unix events py line 197 in make subprocess transport transp = UnixSubprocessTransport self protocol args shell File usr local lib python3 8 asyncio base subprocess py line 36 in init self start args=args shell=shell stdin=stdin stdout=stdout File usr local lib python3 8 asyncio unix events py line 789 in start self proc = subprocess Popen File usr local lib python3 8 subprocess py line 858 in init self execute child args executable preexec fn close fds File usr local lib python3 8 subprocess py line 1704 in execute child raise child exception type errno num err msg err filename FileNotFoundError Errno 2 No such file or directory git ```

It looks like you are close What image are you using for the flow container The default image in that repository based on an older version of Prefect but it s still new enough that it should have Git included we added it to the image in 2 3 1 But if you are using a different image you ll need to make sure Git is installed and included in the system path so Prefect can run it as a subprocess to clone your repository Edit The image you ll need to check is in your `DockerContainer` infrastructure block It looks like the deployment example included in the repo uses <https github com fraibacas prefect orion blob 24cb863f86504f0036421b27515fa97373f8368b flows test flow deployment py L25|a custom image> that it builds atop `prefecthq prefect 2 4 5 python3 8` But if you ve changed the image in your deployment I recommend checking there first slightly smiling face

The DockerContainer infrastructure block was added using the UI so I m not really sure about the image it is using Is there a way to check that Edit in the Dockerfile of the repo I just mentioned it is using `FROM prefecthq prefect 2 4 5 python3 8` However my Dockerfile is using `FROM python latest` Should I change that to `FROM prefecthq prefect 2 7 1 python 3 11`

Ryan Peden · Answer

There s an Image field in the UI you can check If it is blank it will try to default to trying to pull an image that matches the Prefect and Python versions running on the agent

Nils · Answer

Ah that points to the image on GHCR

Ryan Peden · Answer

Right now I remember you mentioned the GHCR image a couple of days ago That image will need Git installed so the GitHub storage block can clone the repository

It works Thanks so much for all your help smile

Unfortunately I m still running into an error neutral face ```Finished in state Failed Flow run encountered an exception ValueError Path root prefect storage 18f49d2d92c043e187b782512881a0c3 does not exist n ``` Does this have anything to do with the Github storage block ` root prefect storage` of course doesn t exist in the repo
