## docker swarm 으로 그누보드5 로드밸런스 흉내내기
192.168.219.160 docker-master # 도커 마스터(매니저)
192.168.219.184 docker-node1 # 도커 노동자1
nonots@docker-master:~/mydocker$ docker swarm init --advertise-addr 192.168.219.160
Swarm initialized: current node (j0m1pxp35cgd9ylu3aaaa3t2j) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-4m5w9f7sar3xq5xpx0lomsrveqqbm5qda723mi24i2rn8u0ebp-ebuk5n1rcxr21a0ddaln4c7dl 192.168.219.160:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
nonots@docker-master:~/mydocker$
nonots@docker-node1:~$ docker swarm join --token SWMTKN-1-4m5w9f7sar3xq5xpx0lomsrveqqbm5qda723mi24i2rn8u0ebp-ebuk5n1rcxr21a0ddaln4c7dl 192.168.219.160:2377
This node joined a swarm as a worker.

nonots@docker-node1:/home/gnuboard_data$ ls (하면 그누보드 전체소스가 보여야 정상)
