安装Docker，配置阿里云加速和 docker-compose 国内镜像

Centos 7 安装 Docker

官网
https://docs.docker.com/install/

找到 linux --Centos，操作步骤如下
Install Docker Engine on CentOS

直接按照他的操作步骤进行即可
抄录一下

Set up the repository

  sudo yum install -y yum-utilssudo yum-config-manager \--add-repo \https://download.docker.com/linux/centos/docker-ce.repo

Install Docker Engine

 sudo yum install docker-ce docker-ce-cli containerd.io

sudo systemctl start docker
sudo docker run hello-world

设置开机启动的话，继续

$ sudo systemctl list-unit-files |grep docker
docker.service disabled
docker.socket disabled

$ sudo systemctl enable docker

 Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

Ubuntu 安装 Docker

官网
https://docs.docker.com/install/

找到 linux --Ubuntu，操作步骤如下
https://docs.docker.com/engine/install/ubuntu/

直接按照他的操作步骤进行即可
抄录一下

Set up the repository

  sudo apt-get updatesudo apt-get install \ca-certificates \curl \gnupg \lsb-release

Add Docker’s official GPG key:

  curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Use the following command to set up the stable repository

  echo \"deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker Engine

 sudo apt-get updatesudo apt-get install docker-ce docker-ce-cli containerd.io

sudo docker run hello-world

设置开机启动的话，继续

$ sudo systemctl list-unit-files |grep docker

docker.service disabled
docker.socket disabled
$ sudo systemctl enable docker

Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

阿里云 Docker 加速

再次抄录一下，省得每次都忘记，每次都去查找
** 下文中 https://2xxxxxxx.mirror.aliyuncs.com 是我申请后的专属加速器地址，记得换成自己的地址

登录到自己公司的阿里云控制台
https://homenew.console.aliyun.com/home/dashboard/ProductAndService

找到：容器镜像服务

对应 ubuntu 、Centos 。。。，对着修改即可！

 1. 安装／升级Docker客户端推荐安装1.10.0以上版本的Docker客户端，参考文档 docker-ce2. 配置镜像加速器针对Docker客户端版本大于 1.10.0 的用户您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器sudo mkdir -p /etc/dockersudo tee /etc/docker/daemon.json <<-'EOF'{"registry-mirrors": ["https://2xxxxxxx.mirror.aliyuncs.com"]}EOFsudo systemctl daemon-reloadsudo systemctl restart docker截图如下：

国内镜像安装 docker-compose

按照官网操作

sudo curl -L “https://github.com/docker/compose/releases/download/1.24.0/docker-compose-(uname−s)−(uname -s)-(uname−s)−(uname -m)” -o /usr/local/bin/docker-compose

*** 实在太慢！所以，又去找了一下国内镜像

国内镜像参考文章
https://blog.csdn.net/huiyanghu/article/details/82253886

按照以上参考文章抄过来

 curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

果然秒达！接下来设置可运行

chmod +x /usr/local/bin/docker-compose

确认一下：

$docker-compose --version

 docker-compose version 1.24.0, build 0aa59064
