Azure release pipeline - Build agent running SSH command returns weird error codes

In my release pipeline, I am trying to call below command.

echo 'Bring down all dockers'
cd /usr/src/project
sudo docker-compose down
echo 'Setting the ownership of /usr/src/project to $(serviceuser)'
sudo chown -R $(serviceuser) /usr/src/project
sudo chmod -R 777 /usr/src/project

Everything is getting executed fine on the remote machine. But, it reports weird responses back to the agent. as below

So, this makes the job showing as failed. Any suggestion would be helpful.

Thanks!

Solution

  • This is because docker writes those messages to stderr instead of stdout. In Azure DevOps pipeline in SSH task there is option Fail on STDERR which is checked by default. You can try to uncheck this option to see if it works.
