docker在centos7上安装私服镜像各种操蛋修复

centos6.5, docker 1.7.1

vi /etc/sysconfig/docker

#修改

other_args="--insecure-registry 192.168.1.110:5000"

#重启服务

service docker restart

centos7.2,docker 1.9.1;

vi /usr/lib/systemd/system/docker.service

#修改

ExecStart=/usr/bin/docker daemon -H fd:// --insecure-registry 192.168.1.110:5000

#重启服务

systemctl daemon-reload

systemctl restart docker.service

备注:

不同版本的centos,ExecStart可能不同.

比如:  vim /usr/lib/systemd/system/docker.service

[Service]

Type=notify

NotifyAccess=all

EnvironmentFile=-/etc/sysconfig/docker

EnvironmentFile=-/etc/sysconfig/docker-storage

EnvironmentFile=-/etc/sysconfig/docker-network

Environment=GOTRACEBACK=crash

ExecStart=/bin/sh -c '/usr/bin/docker daemon $OPTIONS \

          $DOCKER_STORAGE_OPTIONS \

          $DOCKER_NETWORK_OPTIONS \

          $ADD_REGISTRY \

          $BLOCK_REGISTRY \

          $INSECURE_REGISTRY \

          2>&1 | /usr/bin/forward-journald -tag docker'

这时候就需要修改环境变量/etc/sysconfig/docker

具体请自行检查.

检查docker启动是否正常

[root@centos7 default]# ps -ef | grep docker 

root     110806      1  5 17:17 ?        00:00:39 /usr/bin/docker daemon -H fd:// --insecure-registry 10.7.137.1:5000

如果你能看到加粗的说明你的服务启动正常.

去掉了https,启用了http

////////////////////////////////////////////////////////////////////////////////////////////////////////////////

如果启动参数没有带--insecure-registry 10.7.137.1:5000,push会提示

[root@centos7_2 sysconfig]# docker push 10.7.137.1:5000/centos-slave

The push refers to a repository [10.7.137.1:5000/centos-slave] (len: 1)

unable to ping registry endpoint https://10.7.137.1:5000/v0/

v2 ping attempt failed with error: Get https://10.7.137.1:5000/v2/: EOF

 v1 ping attempt failed with error: Get https://10.7.137.1:5000/v1/_ping: EOF

注意里面的是https.

作为client去registry上pull images的话.

同样也需要修改docker启动的方式,需要指定私服ip方式.
