docker-compose方式启动etcd

网上几乎所有启动etcd容器方式都是以 dokcer run的形式,但是由于生产上采用docker-compose的写法会更方便维护，于是通过不断尝试后，最终测试出了以dokcer-compose启动etcd的方式

1. 以docker run形式启动etcd

# 设置HostIP
export HostIP=192.168.1.102
# 执行etcd安装启动命令
docker run -d -v /usr/share/ca-certificates/:/etc/ssl/certs -p 4001:4001 -p 2380:2380 -p 2379:2379 \
 --restart=always \
 --name etcd registry.cn-hangzhou.aliyuncs.com/coreos_etcd/etcd:v3 \
 /usr/local/bin/etcd \
 -name etcd0 \
 -advertise-client-urls http://${HostIP}:2379,http://${HostIP}:4001 \
 -listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001 \
 -initial-advertise-peer-urls http://${HostIP}:2380 \
 -listen-peer-urls http://0.0.0.0:2380 \
 -initial-cluster-token etcd-cluster-1 \
 -initial-cluster etcd0=http://${HostIP}:2380 \
 -initial-cluster-state new

2. 以docker-compose启动的模式如下

etcd:
    container_name: etcd0
    image: registry.cn-hangzhou.aliyuncs.com/coreos_etcd/etcd:v3
    ports:
      - "2379:2379"
      - "4001:4001"
      - "2380:2380"
    environment:
      - TZ=CST-8
      - LANG=zh_CN.UTF-8
    command: 
      /usr/local/bin/etcd
      -name etcd0 
      -data-dir /etcd-data
      -advertise-client-urls http://${host_ip}:2379,http://${host_ip}:4001
      -listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001
      -initial-advertise-peer-urls http://${host_ip}:2380
      -listen-peer-urls http://0.0.0.0:2380 
      -initial-cluster-token docker-etcd 
      -initial-cluster etcd0=http://${host_ip}:2380
      -initial-cluster-state new 
    volumes:
      - "/data/conf/etcd/data:/etcd-data"
      # - "/data/config/etcd/ca-certificates/:/etc/ssl/certs"
    labels:
      - project.source=
      - project.extra=public-image
      - project.depends=
      - project.owner=LHZ
