# Docker 安装 etcd（集群）、etcd-keeper

## 安装etcd

### 创建一个新的bridge网络

docker network create --driver bridge --subnet=10.2.36.0/16 --gateway=10.2.36.1 peng-rpc

### 拉取etcd镜像

docker pull quay.io/coreos/etcd

### 运行容器

### 通过docker ps命令查看成功运行的容器

CONTAINER ID   IMAGE                        COMMAND                   CREATED          STATUS          PORTS                                                                                  NAMES

### 通过etcdctl member list命令可以查询出所有集群节点的列表即为成功
docker exec -it 27c etcdctl member list
204d370525df28af: name=node3 peerURLs=http://10.2.36.4:2380 clientURLs=http://10.2.36.4:2379 isLeader=false
2db3381ff302973d: name=node2 peerURLs=http://10.2.36.3:2380 clientURLs=http://10.2.36.3:2379 isLeader=false
ffbd0562b8dd25e9: name=node1 peerURLs=http://10.2.36.2:2380 clientURLs=http://10.2.36.2:2379 isLeader=true

#### 无论通过哪一集群节点查询出来的结果都应相同
$docker exec -it af0 etcdctl member list
204d370525df28af: name=node3 peerURLs=http://10.2.36.4:2380 clientURLs=http://10.2.36.4:2379 isLeader=false
2db3381ff302973d: name=node2 peerURLs=http://10.2.36.3:2380 clientURLs=http://10.2.36.3:2379 isLeader=false
ffbd0562b8dd25e9: name=node1 peerURLs=http://10.2.36.2:2380 clientURLs=http://10.2.36.2:2379 isLeader=true

$docker exec -it 596 etcdctl member list
204d370525df28af: name=node3 peerURLs=http://10.2.36.4:2380 clientURLs=http://10.2.36.4:2379 isLeader=false
2db3381ff302973d: name=node2 peerURLs=http://10.2.36.3:2380 clientURLs=http://10.2.36.3:2379 isLeader=false
ffbd0562b8dd25e9: name=node1 peerURLs=http://10.2.36.2:2380 clientURLs=http://10.2.36.2:2379 isLeader=true

## 安装etcd-keeper

### 拉取etcd-keeper镜像

docker pull evildecay/etcdkeeper

### 检查etcd容器ip

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' node1

### 运行容器

docker run -d -p 8080:8080 -e ETCD_SERVERS=http://10.2.36.2:2379 --network=peng-rpc --name etcd-keeper evildecay/etcdkeeper
