現(xiàn)在yum源里的docker比較舊，安裝最新的docker-ce
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
sudo systemctl enable docker
sudo systemctl start docker
修改啟動參數(shù)
如果是私建倉庫，沒有配置SSL，應(yīng)該添加insecure-registries.否則會報連接拒絕。添加后可以pull，如果要push必須登錄！
vi /etc/docker/daemon.json添加。自己添加的鏡像倉庫在pull必須加全名。
{
"insecure-registries": ["registry.cacec.com.cn"]
}
"registry-mirrors": ["https://registry.cacec.com.cn"]
查看docker啟動參數(shù)
systemctl daemon-reload && systemctl restart docker
ps aux | grep docker
