I was trying to set up Rancher HA and was using digital ocean as my cloud provider. Typically I use docker-machine to create my droplet, via something like:
docker-machine -D create
I did notice that docker-machine automatically starts the docker-daemon on port 2376 which gives a port conflict when starting the rancher-ha.sh scripts. I was curious to know if there was any best practices around avoiding this as I can see issues if anyone is using docker-machine to initially create their VM host.
Note, I was able to get around this issue by creating the droplet via the UI, just wondering if there was another way around the issue.
