GCP Cloud Run Job with custom command can't find scripts in WORKDIR

Trying to create two GCP cloud run jobs based on the same docker image, just different commands. I can run the jobs locally using Docker, but when I try and create cloud run jobs on GCP they fail to find the scripts placed in the WORKDIR defined in the Dockerfile. E.g.

#Dockerfile
WORKDIR /app
COPY script1.py .
COPY script2.py .

On my local machine:

docker build -t image .
docker run image python3 script1.py
docker run image python3 script2.py

Both work fine. But if I deploy as cloud run jobs:

    gcloud beta run jobs deploy job1 \
    image=path-to-image:latest \
    --region=region\
    --command="/usr/bin/python3 script1.py"

Fails with:

terminated: Application failed to start: invalid status ::14: could not start container: 
no such file or directory

Note, I seem to need /usr/bin/python3 on cloud run even though python3 is on the path running a docker container locally.

I have tried:

--command="/usr/bin/python3 script1.py"
--command="/usr/bin/python3 script1.py /app/script1.py" 
--command="/usr/bin/python3./script1.py" 

All fail to find the scripts when running as a cloud run job. Anyone know how to make custom commands work correctly with WORKDIR?

Cloud Run overrides the CMD used in the Dockerfile when a custom command is specified in the gcloud beta run jobs deploy command. In your situation, this means that you must explicitly specify the path of the script because the python3 command is not run by default.

Docker

WORKDIR /app 
COPY script1.py . 
COPY script2.py . 
CMD ["python3", "script1.py"]

Then, in the gcloud beta run jobs deploy command, you can pass the path to the script as an argument:

Sample:

gcloud beta run jobs deploy job1 image=path-to-image:latest --region=region --args="/app/script1.py"

Christian is correct, but for completeness I'm showing custom command and args to the job. The thing that confused me (should have realized) is that a command cannot contain spaces, i.e. it really must be a command, not a command + args. So pass the command and args separately.

# Dockerfile
WORKDIR /app 
COPY script1.py . 
COPY script2.py . 
#CMD whatever, we will override it

To deploy equivalent jobs on GCP:

gcloud beta run jobs deploy job1 \
    --image=path-to-image:latest \
    --region=region\
    --command="/usr/bin/python3"
    --args="script1.py"

gcloud beta run jobs deploy job2 \
    --image=path-to-image:latest \
    --region=region\
    --command="/usr/bin/python3"
    --args="script2.py"
