I'm using docker-compose and docker swarm. I have created a docker-mgt server from which I did a docker-machine to setup a swarm cluster consisting of a swarm master and two swarm-agents.
I have created an Express app that gets started in a container and it seems the swarm master decided to have it on agent1. Then I have also a Wordpress site (example from the docker compose site) that I'm running with docker-compose on Docker Swarm.
cloud-user@docker-mgt:~/wordpress$ docker-compose up
wordpress_db_1 is up-to-date
Creating wordpress_web_1
ERROR: Error: image library/wordpress_web:latest not found

So it does have the wordpress_web:latest available and still it complains.
When running this wordpress app on a seperate docker host (not part of the swarm cluster) it runs just fine. To exclude a mistake on the wordpress app, I also tried another complete different app consisting of two containers (with docker-compose) and it is exactly the same issue.
I'm beginning to think that docker compose and swarm can not work together smoothly but that's hard to believe of course.

You might want to try out Rancher, it uses compose and makes it simple to deploy applications across broad types of infrastructure, while keeping native docker syntax and using compose. GitHub Website",
