Hello everyone, I'm trying to get a deployment to a docker worker pool to work, but I'm getting the following error:

prefect.utilities.dockerutils.BuildError: manifest for prefecthq/prefect:3.0.11-python3.11 not found: manifest unknown: manifest unknown

The deploy call looks like this:

my_function.deploy(
        name=deployment_name,
        work_pool_name="my-docker-pool",
        image="my-first-deployment-image:tutorial",
        push=False,
        job_variables={
            "image_pull_policy": "Never",
            "auto_remove": True,
            "env": {
                "PREFECT_API_URL": "<http://host.docker.internal:4200/api>",
                "PREFECT_SERVER_API_HOST": "0.0.0.0",
            },
        },
    )

I can provide further information as required, but I am unsure where to start looking. This was working well with prefect 2. Notice that it is not my custom image that it does not found, but an underlying prefect one

Could it be that it doesn't find your Dockerfile?

It has issue with the prefect docker image it seems, not my custom image. If I add build=False, it actually runs without issues.

3.0.11 has not been released, 3.0.10 is the latest prefect version

That's what I gathered, yet, I'm not setting the version myself to 3.0.11 so it must be picking it up by mistake somewhere else and I couldn't find a way to overwrite it with the correct version

oh, interesting. can you share the dockerfile you used to build

my-first-deployment-image:tutorial

?

The Dockerfile with which I'm running the deploy function above is:

FROM python:3.11 as base

FROM base as docker
RUN apt-get update && \
    apt-get install -qy curl && \
    curl -sSL <https://get.docker.com/> | sh

FROM docker as app
WORKDIR /app
RUN pip install httpx prefect-client prefect-docker
COPY ./src .

(essentially a docker-outside-docker setup) But dockerfile for

my-first-deployment-image:tutorial

is simpler:

FROM python:3.11 as base
RUN pip install prefect
WORKDIR /extraction
COPY ./* .

(which I assume could have used an install of prefect-client only) These work without problem when setting build to false and building the image myself, so there might be something there

thank you! it seems like when we build the image on your behalf, we are not handling the nightly `dev` releases properly when selecting an image tag we'll get that fixed

That makes sense. Glad I could contribute a tiny bit to the library. Thanks for the follow-through and all the work you guys do!
