[root@test01 ~]# cat /etc/docker/daemon.json {"registry-mirrors": [""],"insecure-registries":["192.168.1.30:5000"]}
如果不这样配置,结果如下。这个问题可能是由于客户端采用https,docker registry未采用https服务所致。一种处理方式是把客户对地址“192.168.1.30:5000”请求改为http
[root@test01 ~]# docker push 192.168.1.30:5000/ The push refers to a repository [192.168.1.30:5000/centos] Get http: server gave HTTP response to HTTPS client
[root@test01 ~]# docker run -d -p 5000:5000 --privileged=true -v /opt/data/registry:/tmp/registry --name='docker-registry' registry
参数说明:
-v /opt/data/registry:/tmp/registry :默认情况下,会将仓库存放于容器内的/tmp/registry目录下,指定本地目录挂载到容器 –privileged=true :CentOS7中的安全模块se把权限禁掉了,参数给容器加特权,不加上传镜像会报权限错误(OSError: [Errno 13] Permission denied: ‘/tmp/registry/repositories/liibrary’)或者(Received unexpected HTTP status: 500 Internal Server Error)错误
[root@test01 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/wordpress latest 346b1443b020 30 hours ago 407 MB [root@test01 ~]# docker push 192.168.1.30:5000/wordpress The push refers to a repository [192.168.1.30:5000/wordpress] An image does not exist locally with the tag: 192.168.1.30:5000/wordpress [root@test01 ~]#
根据提示,我们知道需要修改一下tag才能上传
[root@test01 ~]# docker tag docker.io/wordpress 192.168.1.30:5000/wordpress [root@test01 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE 192.168.1.30:5000/wordpress latest 346b1443b020 30 hours ago 407 MB docker.io/wordpress latest 346b1443b020 30 hours ago 407 MB [root@test01 ~]# docker push 192.168.1.30:5000/wordpress The push refers to a repository [192.168.1.30:5000/wordpress] 3d7c1bb6ce9f: Pushed
[root@test01 ~]# docker pull 192.168.1.30:5000/wordpress
