mkdir -p /opt/etcd

 

2.进入目录创建yml文件
cd /opt/etcd

vi docker-compose.yml

 

version: "3"
services:
  etcd:
    container_name: etcd
    hostname: etcd
    image: registry.cn-shenzhen.aliyuncs.com/hxlk8s/etcd:v3.5.5
    volumes:
      - "./etcd/data:/bitnami/etcd/data"
    environment:

    ports:
      - 2379:2379
      - 2380:2380

 

 

3.启动
cd /opt/etcd
docker compose up -d

 

4.重新部署命令

docker compose start

 

6.下载客户端

wget https://github.com/etcd-io/etcd/releases/download/v3.5.5/etcd-v3.5.5-linux-amd64.tar.gz

[root@node2 soft]# cd /soft
[root@node2 soft]# tar -xvf etcd-v3.5.5-linux-amd64.tar.gz
[root@node2 soft]# cd etcd-v3.5.5-linux-amd64

 

7.验证使用

[root@node2 etcd-v3.5.5-linux-amd64]# ./etcdctl member list
8e9e05c52164694d, started, default, http://localhost:2380, http://0.0.0.0:2379, false
[root@node2 etcd-v3.5.5-linux-amd64]# ./etcdctl -w table --endpoints=192.168.1.106:2379 endpoint health
