docker 四 搭建本地仓库 Registry

简述：Docker 已经将Registry开源，其本身也是一个容器。
1，拉取registry 镜像
------ docker pull registry
[root@localhost docker]# docker pull 10.0.0.4:5000/nginx Using default tag: latest latest: Pulling from nginx 000eee12ec04: Pull complete eb22865337de: Pull complete bee5d581ef8b: Pull complete Digest: sha256:189cce606b29fb2a33ebc2fcecfa8e33b0b99740da4737133cdbcee92f3aba0a Status: Downloaded newer image for 10.0.0.4:5000/nginx:latest 10.0.0.4:5000/nginx:latest
2，修改配置文件/etc/docker/daemon.json 将宿主机的IP 添加进去
{
“insecure-registries”:[“10.0.0.4:5000”], ------------------->>>>>>> # 千万要注意逗号
}
3，启动 registry 容器
docker run --name registry -d -p 5000:5000 -v /myregistry/:/var/lib/registry
4,测试Registry 是否工作正常
curl http://10.0.0.4:5000/v2/_catalog
只要返回值为 {“repositories”:[]} 表示工作正常。
[root@localhost docker]# curl http://10.0.0.4:5000/v2/_catalog
{"repositories":["nginx"]}
5,给本地Image打上本地Registry 标签。
docker tag nginx 10.0.0.4:5000/nginx
[root@localhost docker]# docker image rm 10.0.0.4:5000/nginx Untagged: 10.0.0.4:5000/nginx:latest Untagged: 10.0.0.4:5000/nginx@sha256:189cce606b29fb2a33ebc2fcecfa8e33b0b99740da4737133cdbcee92f3aba0a [root@localhost docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 231d40e811cd 3 weeks ago 126MB centos latest 0f3e07c0138f 2 months ago 220MB 10.0.0.4:5000/registry latest f32a97de94e1 9 months ago 25.8MB registry latest f32a97de94e1 9 months ago 25.8MB hello-world latest fce289e99eb9 11 months ago 1.84kB [root@localhost docker]# docker tag nginx 10.0.0.4:5000/nginx [root@localhost docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE 10.0.0.4:5000/nginx latest 231d40e811cd 3 weeks ago 126MB nginx latest 231d40e811cd 3 weeks ago 126MB centos latest 0f3e07c0138f 2 months ago 220MB 10.0.0.4:5000/registry latest f32a97de94e1 9 months ago 25.8MB registry latest f32a97de94e1 9 months ago 25.8MB hello-world latest fce289e99eb9 11 months ago 1.84kB
在镜像的前面加上了运行 registry 的主机名称和端口。
镜像名称由 repository 和 tag 两部分组成。而 repository 的完整格式为：[registry-host]:[port]/[username]/xxx
只有 Docker Hub 上的镜像可以省略 [registry-host]:[port] 。
6,上传Image到Registry
[root@localhost ~]# docker push 10.0.0.4:5000/nginx
[root@localhost ~]# docker push 10.0.0.4:5000/nginx The push refers to repository [10.0.0.4:5000/nginx] 4fc1aa8003a3: Pushed 5fb987d2e54d: Pushed 831c5620387f: Pushed latest: digest: sha256:189cce606b29fb2a33ebc2fcecfa8e33b0b99740da4737133cdbcee92f3aba0a size: 948
7,删除Registry 中的Image
删除镜像
docker exec <Registry-容器名> rm -rf /var/lib/registry/docker/registry/v2/repositories/<镜像名>
------------------- 或是registry ID
具体代码：
[root@localhost ~]# vi /etc/docker/daemon.json
[root@localhost ~]# cat /etc/docker/daemon.json
{
"insecure-registries":["10.0.0.4:5000"],
"registry-mirrors":["https://tpmrvmq9.mirror.aliyuncs.com"]
}
