Docker已经将Registry开源，Registry本身也是一个容器。
1. 修改配置/etc/docker/daemon.json，去掉docker默认的https的访问
里面的内容是一个json对象,加上一项insecure-registries:
{
"insecure-registries":["172.16.65.150:5000"],
"registry-mirrors": ["http://2555a638.m.daocloud.io"]
}
2. 启动Registry容器
root@Docker001:~# docker run --name registry -d -p 5000:5000 -v /myregistry/:/var/lib/registry registry:2 Unable to find image ‘registry:2‘ locally 2: Pulling from library/registry 81033e7c1d6a: Pull complete b235084c2315: Pull complete c692f3a6894b: Pull complete ba2177f3a70e: Pull complete a8d793620947: Pull complete Digest: sha256:6cd209f81e188e8eaa13fad9b670fb1a4e9c7776a73b3881b69834fe5ddfb193 Status: Downloaded newer image for registry:2 385252aac02931701c4cae4233d1b12447b5b8b98ba6b337121d2f4a03e78709 root@Docker001:~# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 385252aac029 registry:2 "/entrypoint.sh /e..." 9 seconds ago Up 8 seconds 0.0.0.0:5000->5000/tcp registry
3. 测试Registry是否工作正常
root@Docker001:~# curl http://172.16.65.150:5000/v2/_catalog
{"repositories":[]}
root@Docker001:~#
只要返回值为 {"repositories":[]} 表示工作正常。
4. 给本地Image打上本地Registry标签
root@Docker001:~# docker tag centos-with-vim 172.16.65.150:5000/centos-with-vim root@Docker001:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos-with-vim latest c00312958340 5 days ago 359 MB 172.16.65.150:5000/centos-with-vim latest c00312958340 5 days ago 359 MB httpd latest 01154c38b473 2 weeks ago 177 MB debian latest 1b3ec9d977fb 2 weeks ago 100 MB registry 2 d1fd7d86a825 7 weeks ago 33.3 MB centos latest ff426288ea90 7 weeks ago 207 MB hello-world latest f2a91732366c 3 months ago 1.85 kB vincenshen/hello-world v1 f2a91732366c 3 months ago 1.85 kB 172.16.65.150:5000/hello-world latest f2a91732366c 3 months ago 1.85 kB docker001:5000/vincenshen/hello-world v1 f2a91732366c 3 months ago 1.85 kB django latest eb40dcf64078 14 months ago 436 MB root@Docker001:~#
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] 。
5. 上传Image到Registry
root@Docker001:~# docker push 172.16.65.150:5000/centos-with-vim The push refers to a repository [172.16.65.150:5000/centos-with-vim] b00cb99cc959: Pushed e15afa4858b6: Pushed latest: digest: sha256:cc103061080dde196f30aa3cb2a129a3be90dd882c0542f27d44509705802544 size: 741
6. 查看Registry中的Image信息
root@Docker001:~# curl http://172.16.65.150:5000/v2/_catalog
{"repositories":["centos-with-vim"]}
root@Docker001:~# curl http://172.16.65.150:5000/v2/centos-with-vim/tags/list
{"name":"centos-with-vim","tags":["latest"]}
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>
清理配置信息
docker exec <Registry-容器名> bin/registry garbage-collect /etc/docker/registry/config.yml
