Docker入门环境安装

环境:mac 10.13.4 , Docker version 18.03.1-ce,Centos7
Docker官网
前言
目前docker提供ce(community edition)社区版本和ee(enterprise edition)企业版本.选择ce版本即可.

Docker下载安装

Centos7安装

1.安装engine版本(有问题弃用)

2.添加docker下载仓库

$ vim /etc/yum.repos.d/docker.repo
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever
enabled=1
gpgcheck=1
gpgkey=http://yum.dockerproject.org/gpg

$ yum update
$ docker install -y docker-engine

3.启动

$ systemctl start docker

安装CE版本

1.卸载旧版本

$ yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

2.安装依赖工具

$ yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

3.安装docker官方仓库(失败 使用阿里云仓库)

$ yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

4.如果上面执行后如下报错,添加阿里云的源即可.

Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo

上面命令错误时,安装阿里云仓库

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

1.安装docker

$ yum install -y docker-ce

2.启动

$ systemctl start docker

3.添加docker hub加速器
