Hi Rama this error indicates that your user code server isn t running Can you share more information about how where you re deploying dagster Docker k8s locally etc

Rama · Answer

Hi Daniel I m deploying locally

daniel · Answer

Can you share more details about your code or project is there a way that we can try to reproduce this problem ourselves

Rama · Answer

I cannot share more details about the code cause it s not my personal project Do you think I miss something when update the version What I did was just update the dockerfile

daniel · Answer

All I can tell you from that error message is that it s having trouble finding the server where your code is running I think we will need more information about your setup in order to be helpful here

Rama · Answer

what information do you need

Rama · Answer

Also I got this error ```Traceback most recent call last File opt conda lib python3 9 runpy py line 188 in run module as main mod name mod spec code = get module details mod name Error File opt conda lib python3 9 runpy py line 147 in get module details return get module details pkg main name error File opt conda lib python3 9 runpy py line 158 in get module details code = loader get code mod name AttributeError AliasedModuleLoader object has no attribute get code ```

daniel · Answer

Ultimately what I need is a way to reproduce the problem myself so if there s a way to share a version of your Dockerfile or code with identifiable information removed I could try running it and see if I hit the same problem

daniel · Answer

I haven t seen the error you just posted before it doesn t look like it s being raised within dagster and might point to a problem with your python setup

Rama · Answer

I used same python setup for dagster 0 14 9 version and worked fine Do you think dagster 1 1 1 only compatible with certain python version

daniel · Answer

1 1 1 should work on the same python versions as before If there are any other logs you can share we could take a look

Rama · Answer

another error logs ```debug error string = created 1670849761 118030908 description DNS resolution failed for docker 4004 C ares status is not ARES SUCCESS qtype=A name=docker is balancer=0 Domain name not found file src core lib transport error utils cc file line 167 grpc status 14 ```

daniel · Answer

I see docker in the error message there are you deploying dagster on docker details of that nature will be really helpful to understand what s going on here and get this fixed

daniel · Answer

If you re running on docker one thing you could do is see if our docker example runs out of the box for you with no changes <https github com dagster io dagster tree master examples deploy docker|https github com dagster io dagster tree master examples deploy docker>

Rama · Answer

Here s my dockerfile ```FROM continuumio miniconda3 latest RUN pip install dagster==1 1 1 dagit==1 1 1 dagster graphql==1 1 1 dagster postgres==0 17 1 dagster aws==0 17 1```

Rama · Answer

I think the issue with the docker image

daniel · Answer

Nothing jumps out to me as a problem from that Dockerfile

daniel · Answer

Did you have any luck running the docker example If you can explain how your deployment differs from that example I may be able to be more helpful

daniel · Answer

Alternately if there s a set of steps we can run ourselves to reproduce the problem that would also work

Rama · Answer

yes I can run the docker example I don t see any different with mine

Rama · Answer

here s my dockerfile ```FROM continuumio miniconda3 latest RUN pip install dagster dagit dagster graphql dagster postgres dagster aws RUN apt get update amp amp apt get install make Create envs RUN conda create n workspace python=3 8 RUN opt conda envs workspace bin pip install dagster dagit dagster graphql dagster postgres dagster aws boto3 GitPython dagster docker```

Rama · Answer

You can run this grpc command to get same error using docker example deployment ```python m dagster grpc h 0 0 0 0 p 4000 f repo py```

daniel · Answer

Got it so just to make sure I understand the repro steps Run the docker example locally by spinning up docker compose Run that command in a separate terminal it will error with a grpc channel InactiveRpcError

Rama · Answer

Yes you ll get error like this ```Traceback most recent call last File Users miniconda3 lib python3 8 runpy py line 183 in run module as main mod name mod spec code = get module details mod name Error File Users miniconda3 lib python3 8 runpy py line 142 in get module details return get module details pkg main name error File Users miniconda3 lib python3 8 runpy py line 153 in get module details code = loader get code mod name AttributeError AliasedModuleLoader object has no attribute get code ```

daniel · Answer

I haven t seen that error before it doesn t look like its part of a Dagster stack trace I can ask around with the rest of the team to see if anybody has seen it before but my suspicion is that the problem lies with your Python environment rather than a problem specific to Dagster my first recommendation would be to try making a new conda environment and see if the problem persists there

daniel · Answer

Errrr wait hang on I m actually reproducing that error with that command slightly smiling face one moment

daniel · Answer

Try running this command instead ```python m dagster grpc h 0 0 0 0 p 4000 f repo py``` Or even better if this works `dagster api grpc h 0 0 0 0 p 4000 f repo py`

daniel · Answer

Did the python m dagster grpc command come from docs somewhere

daniel · Answer

wow what a cryptic error message

Rama · Answer

I read it in <https docs dagster io concepts code locations workspace files> but maybe the docs already updated Because I used version 0 14 9

daniel · Answer

python m dagster api grpc Is actually probably best I bet that will work

Rama · Answer

Thank you so much really appreciate it raised hands
