Docker私有仓库管理和删除本地仓库中的镜像

二、从另外一台机器上上传镜像到docker镜像仓库：

[root@bigdata2 ~]# docker tag centos7-jdk8-nginx:1.0 192.168.18.162:5000/centos7-jdk8-nginx:1.0
[root@bigdata2 ~]# docker images
REPOSITORY                TAG         IMAGE ID      CREATED       SIZE
192.168.18.162:5000/centos7-jdk8-nginx  1.0         bcacd65e2a2e    2 minutes ago    2.18 GB
[root@bigdata2 ~]# docker push 192.168.18.162:5000/centos7-jdk8-nginx:1.0
The push refers to a repository [192.168.18.162:5000/centos7-jdk8-nginx]f018e9c38a66: Pushed
2a47dcd341ef: Pushed
c5dea3bc729a: Pushed
bcc97fbfc9e1: Pushed
1.0: digest: sha256:d907ff2f8eb590209700c01ce85c78d0bc778a4238539d747e4667d68cb52102 size: 1163
[root@bigdata2 ~]#

然后进入docker镜像仓库所在位置：

[root@youx-pub registry]# curl http://192.168.18.162:5000/v2/_catalog
{"repositories":["centos7-jdk8-nginx","nginx"]}
[root@youx-pub registry]# curl http://192.168.18.162:5000/v2/centos7-jdk8-nginx/tags/list
{"name":"centos7-jdk8-nginx","tags":["1.0"]}
[root@youx-pub registry]#

三、本地镜像如何删除，正常是不提供删除功能的，所以使用第三方的插件来进行删除

插件github上的位置：
https://github.com/burnettk/delete-docker-registry-image

1、下载资源

[root@master registry]# curl https://raw.githubusercontent.com/burnettk/delete-docker-registry-image/master/delete_docker_registry_image.py | sudo tee /usr/local/bin/delete_docker_registry_image >/dev/null
sudo chmod a+x /usr/local/bin/delete_docker_registry_image 

2、 设置相关环节变量：

查找REGISTRY_DATA_DIR，命令：
[root@youx-pub registry]# find / -name registry
[root@youx-pub registry]# find / -name registry
/var/lib/docker/overlay2/d72320cd67b42f7ae66342cc6dedab7abe5e89106de8c4919ec8c5a6e5940b09/diff/var/lib/ucf/registry
