使用docker配置etcd集群

docker配置etcd集群与直接部署etcd集群在配置上并没有什么太大差别。

我这里直接使用docker-compose来实现容器化的etcd部署

环境如下：

HostName	IP
etcd1	10.1.61.175
etcd2	10.1.61.176
etcd3	10.1.61.177

etcd1上的docker-compose.yaml内容如下：

version: "2"
services:
  etcd:
    image: hub.dz11.com/library/etcd-amd64:3.1.10
    restart: always
    network_mode: host
    volumes:
      - "/home/www/server/etcd:/data/etcd"
      - "/etc/localtime:/etc/localtime"
    environment:
      ETCDCTL_API: "3"
    command: etcd  -name etcd1 -data-dir /data/etcd -advertise-client-urls http://10.1.61.175:2379 -listen-client-urls http://10.1.61.175:2379,http://127.0.0.1:2379 -initial-advertise-peer-urls http://10.1.61.175:2380 -listen-peer-urls http://0.0.0.0:2380 -initial-cluster-token etcd-cluster-1 -initial-cluster etcd1=http://10.1.61.175:2380,etcd2=http://10.1.61.176:2380,etcd3=http://10.1.61.177:2380 -initial-cluster-state new

etcd2上的docker-compose.yaml内容如下：

version: "2"
services:
  etcd:
    image: hub.dz11.com/library/etcd-amd64:3.1.10
    restart: always
    network_mode: host
    volumes:
      - "/home/www/server/etcd:/data/etcd"
      - "/etc/localtime:/etc/localtime"
    environment:
      ETCDCTL_API: "3"
    command: etcd  -name etcd2 -data-dir /data/etcd -advertise-client-urls http://10.1.61.176:2379 -listen-client-urls http://10.1.61.176:2379,http://127.0.0.1:2379 -initial-advertise-peer-urls http://10.1.61.176:2380 -listen-peer-urls http://0.0.0.0:2380 -initial-cluster-token etcd-cluster-1 -initial-cluster etcd1=http://10.1.61.175:2380,etcd2=http://10.1.61.176:2380,etcd3=http://10.1.61.177:2380 -initial-cluster-state new

etcd3上的docker-compose.yaml内容如下：

version: "2"
services:
  etcd:
    image: dk-reg.op.douyuyuba.com/library/etcd-amd64:3.1.10
    restart: always
    network_mode: host
    volumes:
      - "/home/www/server/etcd:/data/etcd"
      - "/etc/localtime:/etc/localtime"
    environment:
      ETCDCTL_API: "3"
    command: etcd  -name etcd3 -data-dir /data/etcd -advertise-client-urls http://10.1.61.177:2379 -listen-client-urls http://10.1.61.177:2379,http://127.0.0.1:2379 -initial-advertise-peer-urls http://10.1.61.177:2380 -listen-peer-urls http://0.0.0.0:2380 -initial-cluster-token etcd-cluster-1 -initial-cluster etcd1=http://10.1.61.175:2380,etcd2=http://10.1.61.176:2380,etcd3=http://10.1.61.177:2380 -initial-cluster-state new

启动docker-compose:

docker-compose up -d
