从零配置CentOS7的Docker源

1、新建docker源文件，在/etc/yum.repos.d/docker-ce.repo

vim /etc/yum.repos.d/docker-ce.repo


[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://registry.docker-cn.com/linux/centos/7/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-stable-debuginfo]
name=Docker CE Stable - Debuginfo $basearch
baseurl=https://registry.docker-cn.com/linux/centos/7/debug-$basearch/stable
enabled=0
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-stable-source]

enabled=0
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-edge-source]
name=Docker CE Edge - Sources
baseurl=https://registry.docker-cn.com/linux/centos/7/source/edge
enabled=0
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-test]
name=Docker CE Test - $basearch
baseurl=https://registry.docker-cn.com/linux/centos/7/$basearch/test
enabled=0
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-test-debuginfo]
name=Docker CE Test - Debuginfo $basearch
baseurl=https://registry.docker-cn.com/linux/centos/7/debug-$basearch/test

[docker-ce-nightly]

gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-nightly-debuginfo]
name=Docker CE Nightly - Debuginfo $basearch
baseurl=https://registry.docker-cn.com/linux/centos/7/debug-$basearch/nightly
enabled=0
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

[docker-ce-nightly-source]
name=Docker CE Nightly - Sources
baseurl=https://registry.docker-cn.com/linux/centos/7/source/nightly
enabled=0
gpgcheck=1
gpgkey=https://registry.docker-cn.com/linux/centos/gpg

2、更新yum的安装索引

yum makecache fast

3、展示yum里能够提供的docker-ce的版本

yum list docker-ce.x86_64  --showduplicates |sort -r
