Docker 容器未在 Swarm 集群中关闭

Question

On my docker swarm cluster, when I perform a docker stack deploy with a new version of my service's image or do a docker service update --force , the old containers of the service(s) get desired state SHUTDOWN, they remain with a current state running.

However, they don't seem te be actually running, I can't do anything with them, docker logs , docker inspect , docker exec , ... nothing.

The only way to get rid of them is to restart the docker daemon.

What would you consider look at to try to understand and fix this recurring issue?

Answer 1

We faced the same issue a few days ago: Turned out, we had a logging-driver configured, but the logging-server was not available. We stopped using this anyway, but forgot to remove the configuration from the service:

    logging:
      driver: fluentd
      options:
        fluentd-address: localhost:24224
        fluentd-async-connect: "true"

Removing this configuration fixed the issue for future containers. Old instances were still hanging around, but restarting Docker helped.
