Docker学习--2.创建私人仓库

环境

• OS: Ubuntu16.04 X86_64

查询registery

$ docker search registry
NAME                                    DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED
registry                                The Docker Registry 2.0 implementation for...   2196      [OK]
konradkleine/docker-registry-frontend   Browse and modify your Docker registry in ...   200                  [OK]
...

上述第一个即为所需要的私人仓库的镜像。

下载镜像

$ docker pull registry
Using default tag: latest
latest: Pulling from library/registry
d6a5679aa3cf: Pull complete
...
bcd4a541795b: Pull complete
Digest: sha256:5a156ff125e5a12ac7fdec2b90b7e2ae5120fa249cf62248337b6d04abc574c8
Status: Downloaded newer image for registry:latest

启动镜像

$docker run -d -v /home/ly/docker_registry/:/var/lib/registry/ -p 5000:5000 --name myregistry registry
#-v挂载文件，-p映射端口

测试

• 1, 使用curl测试是否启动成功

$ curl -i http://localhost:5000
HTTP/1.1 200 OK
Cache-Control: no-cache
Date: Sun, 16 Sep 2018 10:58:25 GMT
Content-Length: 0
Content-Type: text/plain; charset=utf-8

• 2. 提交一个image并且拉下了

$ docker tag hello-world localhost:5000/myhelloworld
$ docker push localhost:5000/myhelloworld
The push refers to a repository [localhost:5000/myhelloworld]
428c97da766c: Pushed
latest: digest: sha256:70f2bd...4de5 size: 524
---
$ docker pull localhost:5000/myhelloworld
Using default tag: latest
latest: Pulling from myhelloworld
Digest: sha256:70f2bd44b1c349fb6f6fbdfdfc965b1c014f901e72461a95284b48ac29334de5
Status: Image is up to date for localhost:5000/myhelloworld:latest

！！注意！！ 在提交images之后，使用search命令来查看的话出现问题，log显示跟register版本有关，有相关bug：https://github.com/docker/distribution/issues/206

当前无在其他机器上pull images的需求。故而没测试相关问题。
