docker版本為1.13.1需要配置一下daemon.json

配置阿裏雲的docker加速器：

wangpeng@ubuntu:~$ sudo vim /etc/docker/daemon.json 
{
   "registry-mirrors": [
      "https://kv3qfp85.mirror.aliyuncs.com"
    ]
}

2、拉取registry倉庫docker鏡像

wangpeng@ubuntu:~$ sudo docker pull registry

3、創建registry docker進程

wangpeng@ubuntu:~$ sudo docker run -d --name registry --restart=always -v /myregistry:/var/lib/registry registry
wangpeng@ubuntu:~$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
d8f77abe36a7        registry            "/entrypoint.sh /e..."   2 hours ago         Up 2 hours          0.0.0.0:5000->5000/tcp   registry

4、測試上傳一個鏡像

下載一個測試鏡像

wangpeng@ubuntu:~$ sudo docker pull busybox

將busybox鏡像重命名為本地鏡像格式與本地registry相匹配。

鏡像名稱由registry和tag兩部分組成，registry完整格式：[registry_ip]:[registry:port]/[user]/[image_name:version]

wangpeng@ubuntu:~$ sudo docker tag busybox 192.168.56.101:5000/wangpeng/test:v1.0

5、使用docker push命令上傳鏡像

wangpeng@ubuntu:~$ sudo docker push 192.168.56.101:5000/wangpeng/test:v1.0

查看鏡像

wangpeng@ubuntu:~$ curl http://192.168.56.101:5000/v2/_catalog 
{"repositories":["wangpeng/my-image","wangpeng/test"]}

在此需要配置daemon.json的insecure-registries，為了解決https的報錯，因為docker默認使用https協議，但是本地現在只支持http協議

不配置daemon.json的話會出現一下錯誤：

Get https://192.168.56.101:5000/v1/_ping: http: server gave HTTP response to HTTPS clie

配置如下：

wangpeng@ubuntu:~$ sudo vim /etc/docker/daemon.json 
{
   "registry-mirrors": [
      "https://kv3qfp85.mirror.aliyuncs.com"
   ],
   "insecure-registries": [
      "192.168.56.101:5000"
    ]
}

重啟docker進程

wangpeng@ubuntu:~$ sudo systemctl restart docker

上傳報錯的問題就此解決

6、下載鏡像測試一下

wangpeng@ubuntu:~$ sudo docker pull 192.168.56.101:5000/wangpeng/test:v1.0
v1.0: Pulling from wangpeng/test
Digest: sha256:73a74253ed45caebc619d95b1d84e4d67a64e5b6d81e31ac7c496b9c11128d74
Status: Image is up to date for 192.168.56.101:5000/wangpeng/test:v1.0
