Running background command using & causes the step to halt and timeout

[asymness]

I am executing a command like this in the step:
python script.py &
echo Done

This causes the step to get stuck in progress after echoing Done and eventually timeout (after ~10 minutes) whereas it should be done in 10 seconds.
However, if I kill the process (python script.py) manually by SSH'ing to the server, the step completes execution successfully. How can I fix this problem and run background commands successfully?

Other variants I have tried:
nohup python script.py &
disown

Fixed by redirecting all output:
nohup python script.py > nohup.out 2> nohup.err < /dev/null &

@asymness thank you! I faced the same problem. Do you know why it works like this? I tried to find an answer to this question for several hours but found nothing.

For some reason, the action keeps waiting for stdin, stdout, and stderr. That's why we need to redirect all three outputs to free the terminal. That's all I could gather from this...

So I've had a very similar issue with docker compose. As per the suggestion I tried redirecting all three fds (input, output and error), but no luck, my github actions keep running and then timing out and failing.

Here's the script:

nohup sudo docker compose --env-file ./.config/.env up > nohup.out 2> nohup.err < /dev/null &

Any help would be appreciated :)

@Saljooq moving nohup to a command directly under the list of commands on the action worked for me for some reason.

some something like:
.github/deploy.yaml

uses: appleboy/ssh-action@master
        with:
          key: ${{ secrets.KEY  }}
          host: ${{ secrets.HOSTNAME  }}
          username: ${{ secrets.USERNAME  }}
          script: |
            ./some_script

./some_script

nohup ./some_other_script > nohup.out 2> nohup.err < /dev/null &

I changed it to:
.github/deploy.yaml

uses: appleboy/ssh-action@master
        with:
          key: ${{ secrets.KEY  }}
          host: ${{ secrets.HOSTNAME  }}
          username: ${{ secrets.USERNAME  }}
          script: |
            nohup ./some_script > nohup.out 2> nohup.err < /dev/null &
