创建3台虚拟机
还是通过vagrant + virtualbox的方式来创建
- 源码文件夹
- 查看创建虚拟机的源码

boxes = [
{
:name => "swarm-manager",
:mem => "1024",

Vagrant.configure(2) do |config|
config.vm.box = "centos/7"
boxes.each do |opts|
config.vm.define opts[:name] do |config|
config.vm.hostname = opts[:name]
config.vm.provider "vmware_fusion" do |v|
v.vmx["memsize"] = opts[:mem]
v.vmx["numvcpus"] = opts[:cpu]
end
config.vm.provider "virtualbox" do |v|
v.customize ["modifyvm", :id, "--memory", opts[:mem]]
v.customize ["modifyvm", :id, "--cpus", opts[:cpu]]
end
config.vm.network :private_network, type: "dhcp"
end
end
config.vm.synced_folder "./labs", "/home/vagrant/labs"
config.vm.provision "shell", privileged: true, path: "./setup.sh"
end
用SecureCRT连接着3个虚拟机
- 查看每个虚拟机的ip地址
vagrant ssh swarm-manager
#swarm-manager的ip是172.28.128.3
ip a
vagrant ssh swarm-worker1
#swarm-worker1的ip是172.28.128.4
ip a
vagrant ssh swarm-worker2
#swarm-worker2的ip是172.28.128.5
ip a
创建docker-swarm集群
- swarm-manager 建立manager
sudo docker swarm init --help
sudo docker swarm init --advertise-addr=172.28.128.3
- swarm-worker1 和 swam-worker2 连接manager
sudo service docker restart
docker swarm join --token SWMTKN-1-1vafvfucsur6iqd6ba5i2njty6djvzxnhwefsmar4sivcg8isi-dgm1aigtcu1rtotfc8y43j17m 172.28.128.3:2377
- swarm-manager 查看连接状态
docker node ls
PS:这样基本上通过docker-swarm完成集群管理。
