一、docker鏡像加速和信任私有倉庫
1.配置docker-ce鏡像加速和信任私有倉庫harbor.hiibm.com
cat > /etc/docker/daemon.conf <<EOF
{
"registry-mirrors": ["https://ofjd111b.mirror.aliyuncs.com"],
"insecure-registries": ["harbor.hiibm.com"]"
}
EOF
2.修改/usr/lib/systemd/system/docker.service文件
將ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock 修改爲【ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry=harbor.hiibm.com】
3.重啓docker
systemctl daemon-reload
systemctl restart docker
二、如果啓動docker報錯
[root@harbor system]# systemctl status docker.service
● docker.service - Docker Application Container Engine

問題可能出在配置了國內鏡像加速了，而且配置文件寫成了/etc/docker/daemon.json，
解決辦法：修改配置文件/etc/docker/daemon.json爲/etc/docker/daemon.conf。然後systemctl daemon-reload，systemctl restart docker。
隨手點贊正能量~~~！！！
