安装 docker-compose

sudo curl -L https://github.com/docker/compose/releases/download/2.36.0/docker-compose-`uname -s`-`uname -m` -o /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose

如果服务器网络无法下载，可下载后手动安装。

访问 docker-compose，选择适合的版本。uname -s-uname -m 命令分别查看操作系统及CPU架构。
将下载的文件移动到 /usr/local/bin 目录。


sudo mv ~/softwares/docker-compose-linux-x86_64 /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose

验证安装：docker-compose -version

PS：如果想要卸载docker-compose，请执行以下命令
sudo rm /usr/bin/docker-compose

docker-compose 配置示例

version: '3'
services:
  gc-admin:
    build: ./spring-boot-admin
    volumes:
      - "/opt/docker_v/application-cloud.yml:/app/application-cloud.yml"
    ports:
      - "10091:10091"
    networks:
      gcnet:
        ipv4_address: 172.127.0.91
    environment:
      spring.profiles.active: cloud
#  redis:
#    image: "redis:alpine"
  networks:
    gcnet:
      external:
        name: gc-network

构建

docker-compose build

启动

docker-compose up -d
docker-compose ps

The docker-compose run command allows you to run one-off commands for your services. For example, to see what environment variables are available to the web service:
$ docker-compose run web env

停止

docker-compose stop

You can bring everything down, removing the containers entirely, with the down command. Pass –volumes to also remove the data volume used by the Redis container:
$ docker-compose down --volumes
docker-compose rm --force

遇到问题

http: server gave HTTP response to HTTPS client
解决办法：
在 /etc/docker 下，创建 daemon.json 文件，写入：

{
  "debug": true,
  "experimental": false,
  "registry-mirrors": [
    "http://hub-mirror.c.163.com",
    "https://<修改成自己的>.mirror.aliyuncs.com"
  ],
  "insecure-registries": [
    "IP:PORT"
  ]
}

IP:PORT 为harbor私服的IP和端口

重启 docker：

systemctl restart docker.service
sudo service docker restart

docker启动日志：/var/log/upstart/docker.log
