How can I remotely connect to docker swarm?

Question

Is it possible to execute commands on a docker swarm cluster hosted in cloud from my local mac? If yes, how?

I want to execute command such as following on docker sw

Answer 1

Answer to the question can be found here.

What one needs to do for ubuntu machine is define daemon.json file at path /etc/docker with following content:

  {
    "hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]
  }

The above configuration is unsecured and shouldn't be used if server is publicly hosted.

For secured connection use following config:

{
  "tls": true,
  "tlscert": "/var/docker/server.pem",
  "tlskey": "/var/docker/serverkey.pem",
  "hosts": ["tcp://x.x.x.y:2376", "unix:///var/run/docker.sock"]
}

Details for generating certificate can be found here as mentioned by @BMitch.
