linux（centos）快速安装docker

一、安装

安装依赖包

sudo yum install -y yum-utils device-mapper-persistent-data lvm2 

设置阿里云镜像源

sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

安装 Docker-CE
重建 Yum 缓存。
安装 Docker-CE ，请执行一下命令进行安装：

sudo yum install docker-ce

(如果出错：
dnf install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
然后再：sudo yum install docker-ce
)

启动 Docker-CE

sudo systemctl enable docker
sudo systemctl start docker

二、设置私有镜像库

vim /etc/docker/daemon.json

{
    "exec-opts": ["native.cgroupdriver=systemd"],
    "log-driver": "json-file",
    "insecure-registries": ["172.26.82.151:5000"],
    "log-opts": {
      "max-size": "10m"
    }
}

sudo systemctl daemon-reload
sudo systemctl restart docker


docker login 172.26.82.151:5000
