需求
在局域网内，在一台机器上搭建镜像仓库，其他节点能够通过内网镜像仓库pull、push等
实操步骤
- 仓库节点IP：192.168.83.141
- 仓库节点上创建镜像存放目录：
mkdir -p /data/registry - 设置仓库节点上Docker镜像加速：Aliyun
- pull registry：
sudo docker pull registry
[liu@localhost docker]$ sudo docker pull registry
[sudo] liu 的密码：
Using default tag: latest
latest: Pulling from library/registry

Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest
- 运行registry镜像：
sudo docker run -d -v /data/registry:/var/lib/registry -p 5000:5000 --restart=always b8604a3fe854（registry镜像ID），查看容器：
[liu@localhost registry]$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

- 修改HTTP设置：
vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://XXXXXXX.mirror.aliyuncs.com"],
"insecure-registries":["http://192.168.83.141:5000"]
}
-
重启Docker：
sudo systemctl daemon-reload、sudo systemctl restart docker -
客户机上也修改HTTP设置（我这里是Windows Docker Desktop）
使用
- 客户机上先给镜像打标签：
docker tag gisliuliang/test-demo:v0.1 192.168.83.141:5000/test-demo:v0.1 - 客户机上push：
docker push 192.168.83.141:5000/test-demo:v0.1
# docker push 192.168.83.141:5000/test-demo:v0.1
The push refers to repository [192.168.83.141:5000/test-demo]
