这里宿主机ip为：192.168.10.100

修改宿主机hosts

echo '192.168.10.100 registry.cw.net' >> /etc/hosts

配置

docker-compose.yml

# tell docker what version of the docker-compose.yml we're using
version: '3.1'
services:
  registry:
    image: registry
    restart: always
    container_name: registry
    ports:
      - 5000:5000
    volumes:
      - ./registry:/var/lib/registry

修改docker配置文件

vi /etc/docker/daemon.json
{
  "insecure-registries": [
    "registry.cw.net:5000"
  ]
}

启动该容器

docker-compose up -d

测试

准备一个本地镜像
docker pull busybox:latest ⬅️拉取镜像
打标记
docker tag busybox:latest registry.cw.net:5000/busybox
将本地镜像push到本地仓库
docker push registry.cw.net:5000/busybox
从仓库拉取busybox
docker pull registry.cw.net:5000/busybox
删除
docker rmi registry.cw.net:5000/busybox

通过浏览器查看本地镜像列表

http://localhost:5000/v2/ ⬅️空
http://localhost:5000/v2/_catalog ⬅️会看到本地镜像列表

给虚拟机里的docker使用宿主机的仓库

1、修改宿主机hosts

echo '192.168.10.100 registry.cw.net' >> /etc/hosts

2、修改docker配置文件

vi /etc/docker/daemon.json
{
  "insecure-registries": [
    "registry.cw.net:5000"
  ]
}

3、重启docker

systemctl restart docker

正式环境建议用harbor
