1、配置Docker镜像仓库

一、新建docker-compose.yml，内容以下：

version: '3'services:
  docker_registry:
    image: registry:2.7
    ports:
      - 0.0.0.0:22000:5000
    volumes:
      - /mnt/disk/docker/registry:/var/lib/registry
    deploy:
      placement:
        constraints:
          - node.hostname==host-192-168-1-22
      restart_policy:
        condition: on-failure

二、建立DockerSwarm集群

docker swarm init --advertise-addr 192.168.1.22

三、部署镜像仓库

docker stack deploy -c docker-compose.yml docker-registery

四、查看运行状况

docker stack ps docker-registery

五、中止服务

docker stack rm docker-registery

2、配置Docker镜像存储地点，和配置局域网内的不安全镜像仓库：

一、建立配置

sudo mkdir /mnt/disk/docker/dataroot
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "insecure-registries": ["192.168.0.22:22000"],
  "data-root":"/mnt/disk/docker/dataroot"
}
EOF

二、从新加载配置

sudo systemctl daemon-reload
sudo systemctl restart docker

三、查看是否已修改

sudo docker info | grep Root
