centos7下载自定义仓库的镜像设置方法

1、vim /usr/lib/systemd/system/docker.service

Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network.target docker.socket
Requires=docker.socket

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/docker daemon -H fd://
MountFlags=slave
LimitNOFILE=1048576
LimitNPROC=1048576
LimitCORE=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes

[Install]
WantedBy=multi-user.target

将上面的ExecStart后面追加自已的

ExecStart=/usr/bin/docker daemon -H fd:// --insecure-registry=172.16.101.192 

然后重启docker

service docker restart
