Swarm mode and single container

[jwaes]

When i enable SWARM_MODE everything works fine with labels in other stacks. But when i add a label to a single container in the docker host i get this error:

Need some defaults for projectname and for service name for not docker-compose containers.

Can you elaborate?

@einarf

so when i have swarm mode enabled, and use the right labels in a docker-compose file all works fine.

But when i add a single container on that docker host, for example using portainer with the correct labels, as you can see above, while detecting the config, it finds this container, but gets 'None' for the service name. Because this 'single' container does not belong to a docker-compose stack.

Hope that is more clear.
