Rocker-compose cannot pull image if name contains '/' character

[slevental]

Consider example:

namespace: some_nginx_container
containers:
  nginx:
    image: kyma/docker-nginx:latest
    ports:
      - "80:8888"

Output:

> rocker run --pull
INFO[0000] Reading manifest: compose.yml                
INFO[0000] Gathering info about 4 containers            
FATA[0001] Image not found: kyma/docker-nginx:latest make sure that it's exist 

However, it could be pulled directly:

> docker pull kyma/docker-nginx:latest
latest: Pulling from kyma/docker-nginx
902b87aaaec9: Pulling fs layer 
9a61b6b1315e: Pulling fs layer
