Docker Swarm教程
先编写脚本：
#!/bin/bash
# Swarm mode using Docker Machine
managers=3
workers=3
# create manager machines
echo "======> Creating $managers manager machines ...";
for node in $(seq 1 $managers);
do
echo "======> Creating manager$node machine ...";
docker-machine create -d virtualbox manager$node;
done
# create worker machines
echo "======> Creating $workers worker machines ...";
for node in $(seq 1 $workers);
do
echo "======> Creating worker$node machine ...";
docker-machine create -d virtualbox worker$node;
done
# list all machines
docker-machine ls
# initialize swarm mode and create a manager
echo "======> Initializing first swarm manager ..."
docker-machine ssh manager1 "docker swarm init --listen-addr $(docker-machine ip manager1) --advertise-addr $(docker-machine ip manager1)"
# get manager and worker tokens
export manager_token=`docker-machine ssh manager1 "docker swarm join-token manager -q"`
export worker_token=`docker-machine ssh manager1 "docker swarm join-token worker -q"`
echo "manager_token: $manager_token"
echo "worker_token: $worker_token"
# other masters join swarm
for node in $(seq 2 $managers);
do
echo "======> manager$node joining swarm as manager ..."
docker-machine ssh manager$node \
"docker swarm join \
--token $manager_token \
--listen-addr $(docker-machine ip manager$node) \
--advertise-addr $(docker-machine ip manager$node) \
$(docker-machine ip manager1)"
done
# show members of swarm
docker-machine ssh manager1 "docker node ls"
# workers join swarm
for node in $(seq 1 $workers);
do
echo "======> worker$node joining swarm as worker ..."
docker-machine ssh worker$node \
"docker swarm join \
--token $worker_token \
--listen-addr $(docker-machine ip worker$node) \
--advertise-addr $(docker-machine ip worker$node) \
$(docker-machine ip manager1)"
done
# show members of swarm
docker-machine ssh manager1 "docker node ls"
执行脚本完成效果：

======> Initializing first swarm manager ...
Swarm initialized: current node (vawqzf1q3ot3nq6sfrc2up669) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-2i2986fo5jd5n4j0477hyqw0q3ojgavofiz8urpk2tb04spv6c-cscmmfaf84zgx8b6flim0r47p 192.168.99.106:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
manager_token: SWMTKN-1-2i2986fo5jd5n4j0477hyqw0q3ojgavofiz8urpk2tb04spv6c-3dsgxzjnea7yg52h871kxwpq6
