【Linux】Docker swarm集群
1.三台服务器准备 Ubuntu18.04
192.168.0.5 manager
192.168.0.4 node1
192.168.0.8 node2
2.添加以上入/etc/hosts
3.设定hostname
hostnamectl set-hostname manager
hostnamectl set-hostname node1
hostnamectl set-hostname node2
4.分别安装docker
- wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-cli-19.03.6-3.el7.x86_64.rpm
- wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
- wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-19.03.6-3.el7.x86_64.rpm
- yum install -y docker-ce-cli-19.03.6-3.el7.x86_64.rpm containerd.io-1.2.6-3.3.el7.x86_64.rpm docker-ce-19.03.6-3.el7.x86_64.rpm
- systemctl start docker
5.分别配置国内源
- vi /etc/docker/daemon.json
- {
- "registry-mirrors": ["http://hub-mirror.c.163.com"]
- }
- systemctl daemon-reload
- systemctl restart docker
6.分别安装criu
- yum install -y criu
7.manager节点初始化swarm集群
[root@manager ~]# docker swarm init --advertise-addr 192.168.0.105 Swarm initialized: current node (jy9rsowc1xbiroxvtami7yl18) is now a manager. To add a worker to this swarm, run the following command: docker swarm join --token SWMTKN-1-4v55ca4vw1t5gihtiay5pu0qdzpof75km0ke3gsapxlllx4ush-eg1u7serdhg729le2el7h0s17 192.168.0.105:2377 To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
8.在node节点执行join加入集群
docker swarm join --token SWMTKN-1-4v55ca4vw1t5gihtiay5pu0qdzpof75km0ke3gsapxlllx4ush-eg1u7serdhg729le2el7h0s17 192.168.0.105:2377
9.manager节点查看节点
[root@manager ~]# docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS ENGINE VERSION jy9rsowc1xbiroxvtami7yl18 * manager Ready Active Leader 18.03.1-ce xpnx8viazr8c0lctvgbsd94up node1 Ready Active 18.03.1-ce 41pfh71ycle45opuhixoe5w14 node2 Ready Active 18.03.1-ce
