如何搭建一个含有docker的零碎开发环境，有如下三种办法：

装置

1. 手动装置

应用vagrant启动零碎后，手动装置
https://docs.docker.com/install/linux/docker-ce/centos/

sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-enginesudo yum install -y yum-utils device-mapper-persistent-data lvm2sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo# 如果想装置特定版本，则应用 # sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.iosudo yum install -y docker-cesudo systemctl start docker

2. vagrant主动装置

在vagrant创立零碎后主动搭建docker环境，config.vm.provision "shell"可能在虚拟机被创立的时候主动执行

 config.vm.provision "shell", inline: <<-SHELL    sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine    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 install -y docker-ce    sudo systemctl start docker  SHELL

3. docker-machine主动装置

详见下节

4. 脚本主动装置

curl -fsSL https://get.docker.com -o get-docker.sh

卸载

sudo yum remove docker-cesudo rm -rf /var/lib/docker

常见问题

  1. 首次装置，启动失败，定位问题所在
# 通过systemctl来排查systemctl status docker# 间接运行systemctl的execStart来排查/usr/bin/dockerd
