Deploying Tags in Dokku
Dokku is an tiny open source PAAS. Pulling and tagging existing images isn't a directly supported feature inside Dokku, so you must use Docker to first pull a tag the image.
- Use Docker to login to Docker Hub if the repo isn't public
$ sudo docker -u <dockerhub_username>
Note: -p is only used when passing the password in line
- Pull the image from Docker Hub
