docker在centos7上安裝私服鏡像各類操蛋修復

centos6.5, docker 1.7.1

vi /etc/sysconfig/docker

#修改

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

#重啓服務

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

#重啓服務

systemctl daemon-reload

systemctl restart docker.service

備註:

不一樣版本的centos,ExecStart可能不一樣.

好比:  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'

這時候就須要修改環境變量/etc/sysconfig/docker

具體請自行檢查.

檢查docker啓動是否正常

[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

若是你能看到加粗的說明你的服務啓動正常.

去掉了https,啓用了http

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

若是啓動參數沒有帶--insecure-registry 10.7.137.1:5000,push會提示

[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

注意裏面的是https.

做爲client去registry上pull images的話.

一樣也須要修改docker啓動的方式,須要指定私服ip方式.
