Question

Unable to get python app running from a remote and close connection

I have a bitbucket pipeline file bitbucket-pipelines.yml which executes the file deploy.sh on my DO droplet each time a new commit is made to the main branch.

On DO, deploy.sh in turn calls pull.sh which performs a set of actions:

  1. If it exists, kill the existing refgator-api.py process
  2. Change to the directory containing the repo
  3. Pull from the repo
  4. Change to the directory containing refgator-api.py
  5. Execute python3 refgator-api.py

It’s at this last step that my bitbucket pipeline will continue executing (consuming all my build minutes).

Is there any way that I can run the file refgator-api.py and exiting the session whilst still allowing it to run?

I’ve attempted using nohup and & as well as exit. Neither result in a state where the pipeline disconnects from the DO droplet and stops and the application is running on the droplet.

bitbucket-pipelines.yml

image: atlassian/default-image:latest

pipelines:
    default:
      - step:
          script:
              - cat ./deploy.sh | ssh -tt root@xxx.xxx.xxx.xxx
              - echo "Deploy step finished"

deploy.sh

echo "Deploy Script Started"
cd
sh pull.sh
echo "Deploy script finished execution"

pull.sh

## Kills the current process which is restarted later
kill -9 $(pgrep -f refgator-api.py)

## And change to directory containing the repo
cd eg-api

## Pull from the repo
export GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa.pub"
GIT_SSH_COMMAND="ssh -v" git pull git@bitbucket.org:myusername/myrepo.git

## Change to directory containing the python file to execute
cd refgator-api
python3 refgator-api.py &

Hi there @christianmacedo,

I could suggest using Supervisor as a more robust solution. You can follow the steps on how to install Supervisor here:

https://www.digitalocean.com/community/tutorials/how-to-install-and-manage-supervisor-on-ubuntu-and-debian-vps

You could again put the python3 refgator-api.py and then specify the path to the script in the supervisor config file as described in the tutorial:

command=/path/to/your_script.sh

Hope that this helps! Regards, Bobby
