This article is about how docker swarm looks for error messages that service cannot start. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

When you run the docker stack deploy-c xxxxx.yml stack_name command, you will sometimes encounter some services that cannot start the container properly. You can view the information by using the following command:

Docker service ps-- no-trunc {serviceName}

After executing the command, you will see an error message similar to the following:

[root@manager crs2sc] # docker service ps shd_cfg2-- no-trunc

ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS

From the information, you can see that there is a problem with the docker image. Re-pull the image will solve the problem.
