replicate docker swarm cluster

Question

I have the Docker Swarm cluster setup in my servers. I have 3 manager nodes and 9 working nodes. 

I would like to replicate the same in the in my production server but using scripts instead of commands.

Any help would be appreciated.

There is nothing like in-built utilities for that you can use the command like this :

You can create your custom script like this :

for i in `cat app_server.txt` ; do echo $i ; ssh -i /path/to/your_key.pem  $i "sudo docker swarm join --token your-token-here ip-address-of-manager:port" ; done

Here app_server.txt is the ip address of your worker node that you want to add in your swarm.

--token : your token generated by manager on docker swarm init
