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
