docker本地仓库（本地镜像仓库）环境搭建

容器镜像生成以后，需要保存到镜像仓库，需要的时候从仓库中拉取镜像，创建容器并运行。

选择节点17.83节点搭建本地仓库。

1. 下载registry 镜像

docker pull registry

2. 创建registry容器并开放端口

docker run -d -p 5000:5000 --name=registry --restart=always --privileged=true  -v /data/registry:/var/lib/registry  registry:latest

-p指定端口，一内一外；-v表示挂载，前者是宿主机，后者是容器

在17.85节点上配置。

3. 在17.85节点上配置镜像仓库的地址

在/etc/docker/daemon.json中配置：

{
  "insecure-registries": ["192.168.17.83:5000"]
}

重启docker服务

systemctl daemon-reload
systemctl restart docker.service

4. 给镜像打标签

docker images
REPOSITORY                                           TAG       IMAGE ID       CREATED         SIZE
ruoyi_ruoyi-server                                   latest    23136f0f1801   44 hours ago    728MB


docker tag ruoyi_ruoyi-server:latest 192.168.17.83:5000/ruoyi-server
[root@k8s-node85 ~]# docker images
REPOSITORY                                           TAG       IMAGE ID       CREATED         SIZE
192.168.17.83:5000/ruoyi-server                      latest    23136f0f1801   44 hours ago    728MB
ruoyi_ruoyi-server                                   latest    23136f0f1801   44 hours ago    728MB

linux查看镜像

curl http://192.168.17.83:5000/v2/_catalog

windows查看，浏览器直接访问http://192.168.17.83:5000/v2/_catalog

5. 上传镜像

docker push 192.168.17.83:5000/ruoyi-server
Using default tag: latest
The push refers to repository [192.168.17.83:5000/ruoyi-server]

6. 在17.81节点上下载镜像

配置/etc/docker/daemon.json

{
  "insecure-registries": ["192.168.17.83:5000"]
}

重启docker

systemctl daemon-reload
systemctl restart docker.service

从本地仓库拉取镜像

docker pull 192.168.17.83:5000/ruoyi-server

查看下载的镜像：

docker images
REPOSITORY                                                        TAG        IMAGE ID       CREATED         SIZE
192.168.17.83:5000/ruoyi-server                                   latest     23136f0f1801   45 hours ago    728MB

查看仓库中的镜像：

curl http://192.168.17.83:5000/v2/_catalog
