docker swarm集群搭建过程对比k8s区别解析

# 修改三台机器名称
hostnamectl set-hostname manage1
hostnamectl set-hostname worker1 
hostnamectl set-hostname worker2 

# 所有节点开放Swarm必需端口
firewall-cmd --permanent --add-port={2377/tcp,7946/tcp,7946/udp,4789/udp}
firewall-cmd --reload

yum -y update
# 安装基础依赖
yum install -y yum-utils device-mapper-persistent-data lvm2
# 添加docker源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
创建yum缓存
yum makecache --timer
安装docker
yum -y install docker-ce
# 启动docker并设置开机自启
systemctl enable --now docker

# 在 manager1 机器上创建了一个 Swarm
docker swarm init --advertise-addr 10.10.10.11

docker swarm join-token worker

# 在Manager节点上执行
docker node promote <worker-node-id>
# 验证节点角色
docker node ls
