Docker详细安装步骤，处理cannot install the best candidate for the job
一、安装依赖
执行命令 sudo yum install -y yum-utils
[root@iZbp15rmf8lyj2yhq136ebZ ~]# sudo yum install -y yum-utils
Loaded plugins: fastestmirror

Complete!
二、指定docker 远程仓库
执行命令 sudo yum-config-manager --add-repo https://download.docker.com/linux/cent
[root@iZbp15rmf8lyj2yhq136ebZ ~]# sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
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
repo saved to /etc/yum.repos.d/docker-ce.repo
三、没有可用软件包docker-ce
现在执行 如下命令来进行docker的安装
yum install docker-ce
但不幸的是。。。
安装中可能会遇到这个问题
没有可用软件包 docker-ce。
错误：无须任何处理
可以直接执行增加镜像包
yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
四、执行yum install docker-ce
现在执行 如下命令来进行docker的安装
yum install docker-ce
但不幸的是。。。
安装中可能会遇到这个问题
https://download.docker.com/linux/cent/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
细心的同学应该都发现了错误信息里提示了处理的方法
yum-config-manager --save --setopt=download.docker.com_linux_cent.skip_if_unavailable=true
当执行完成后
当执行完上面的这些操作，再执行
sudo yum install docker-ce
也许会成功，但也可能会继续遇到下面的问题。。。
五、异常Cannot download repodata/repomd.xml
1、安装yum install docker-ce 提示异常
[root@localhost ~]# yum install docker-ce
Docker CE Stable - aarch64 128 kB/s | 48 kB 00:00
created by dnf config-manager from https://download.docker.com/linux/cent 247 B/s | 365 B 00:01
Errors during downloading metadata for repository 'download.docker.com_linux_cent':
- Status code: 404 for https://download.docker.com/linux/cent/repodata/repomd.xml (IP: 13.224.250.127)
错误：Failed to download metadata for repo 'download.docker.com_linux_cent': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
这里发现download 一直提示404，于是cd 到该/etc/yum.repos.d/目录下去看看究竟是怎么回事
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
docker-ce.repo download.docker.com_linux_cent.repo openEuler.repo
[download.docker.com_linux_cent]
name=created by dnf config-manager from https://download.docker.com/linux/cent
baseurl=https://download.docker.com/linux/cent
enabled=1
~
~
2、在浏览器输入对应地址https://download.docker.com/linux/centos/发现这个才是对的
3、于是果断将 https://download.docker.com/linux/cent改成https://download.docker.com/linux/centos/7/source/stable/
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
docker-ce.repo download.docker.com_linux_cent.repo openEuler.repo
[download.docker.com_linux_cent]
#name=created by dnf config-manager from https://download.docker.com/linux/cent
name=created by dnf config-manager from https://download.docker.com/linux/centos/7/source/stable/
#baseurl=https://download.docker.com/linux/cent
baseurl=https://download.docker.com/linux/centos/7/source/stable/
enabled=1
4、再把里面的$releasever全部改成7
vi /etc/yum.repos.d/CentOS-Base.repo
#命令行情况下输入,将文件中$releasever全部改成7
:%s/$releasever/7/g
5、最后执行yum install docker安装成功
【注意】不要使用yum install docker-ce 安装会提示如下错误
六、Error: Failed to download metadata for repo ‘download.docker.com_linux_cent’: Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
又是一篇错误
Failed to set locale, defaulting to C.UTF-8
created by dnf config-manager from https://download.docker.com/linux/cent 186 B/s | 365 B 00:01
Errors during downloading metadata for repository 'download.docker.com_linux_cent':

于是修改了下载的配置
[root@localhost speedtest-cli]# vim /etc/yum.repos.d/docker-ce.repo
1
七、错误：软件包：containerd.io-1.5.11-3.1.el7.x86_64 (docker-ce-stable) 需要：container-selinux >= 2:2.74
也许还会遇到如下问题
[root@localhost ~]# yum install docker-ce

错误：无须任何处理
执行缺失依赖安装
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
1
vi /etc/yum.repos.d/CentOS-Base.repo
#命令行情况下输入,将文件中$releasever全部改成7
:%s/$releasever/7/g
然后clean
yum clean all
再建立缓存
yum makecache
最后再执行
yum install docker-ce
如果没有异常，恭喜到此成功不许要看下面的异常处理了。
八、安装符合自己系统的containerd.io
修改完了再执行sudo yum install docker-ce
现在提示的错误到时少了一大截

[root@localhost speedtest-cli]# yum-config-manager --save --setopt=download.docker.com_linux_cent.skip_if_unavailable=true
Failed to set locale, defaulting to C.UTF-8
但是还是有，于是去盲目安装containerd.io，如CentOS 上 安装Docker （解决安装过程中遇到的问题）
当初我根据资料直接拷贝进行containerd.io的安装(选了一个最新版本)，最后安装完了不是自己系统所缺失的；于是白安装了，问题依然在。
最后兜兜转转才发现，不是每一个人都适合自己，没有最好的只有最适合的。于是终于明白我们得根据自己系统版本来安装对应的版本！
1、查看自己系统的版本
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 8.5.2111
2、根据自己的系统版本
去官网https://download.docker.com/linux/centos/ 找到自己对应的版本
我是8.5
按照/x86_64/edge/Packages/这个目录一直点进去
发现了一个我一直缺少的io
安装所需 io
[root@localhost speedtest-cli]# yum install https://download.docker.com/linux/centos/8/x86_64/edge/Packages/containerd.io-1.3.7-3.1.el8.x86_64.rpm
这里安装发现与原来安装过的1.2冲突了
Error:
Problem: problem with installed package containers-common-2:1-2.module_el8.5.0+890+6b136101.noarch
- package containers-common-2:1-2.module_el8.5.0+890+6b136101.noarch requires runc, but none of the providers can be installed
- package containerd.io-1.2.13-3.2.el7.x86_64 conflicts with containerd provided by containerd.io-1.3.7-3.1.el8.x86_6
那就先卸载再说
root@localhost speedtest-cli]# yum remove docker-ce docker-ce-cli containerd.io
然后再执行
yum install https://download.docker.com/linux/centos/8/x86_64/edge/Packages/containerd.io-1.3.7-3.1.el8.x86_64.rpm
1
九、再执行yum install docker-ce
[root@localhost speedtest-cli]# yum install docker-ce
Failed to set locale, defaulting to C.UTF-8
created by dnf config-manager from https://download.docker.com/linux/cent 94 B/s | 365 B 00:03

哈哈哈看这下终于成功了
十、验证安装
执行命令
1、sudo docker version 或者 docker –v（查看docker 版本信息）
[root@iZbp15rmf8lyj2yhq136ebZ ~]# sudo docker version
Client: Docker Engine - Community
Version: 19.03.5
API version: 1.40
Go version: go1.12.12
Git commit: 633a0ea
Built: Wed Nov 13 07:25:41 2019
OS/Arch: linux/amd64
Experimental: false
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
2、docker 版本简要信息
执行命令 docker -v
[root@iZbp15rmf8lyj2yhq136ebZ ~]# docker -v
Docker version 19.03.5, build 633a0ea
2、docker --help （帮助）
[root@iZbp15rmf8lyj2yhq136ebZ ~]# docker --help
Usage: docker [OPTIONS] COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/root/.docker")
-c, --context string Name of the context to use to connect to the daemon (overrides
DOCKER_HOST env var and default context set with "docker context use")
-D, --debug Enable debug mode
-H, --host list Daemon socket(s) to connect to
-l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default
wait Block until one or more containers stop, then print their exit codes
Run 'docker COMMAND --help' for more information on a command.
3、查看某个命令具体配置
[root@iZbp15rmf8lyj2yhq136ebZ ~]# docker rmi --help
Usage: docker rmi [OPTIONS] IMAGE [IMAGE...]
Remove one or more images
Options:
-f, --force Force removal of the image
--no-prune Do not delete untagged parents
4、docker详细信息查看
执行命令docker info
[root@iZbp15rmf8lyj2yhq136ebZ ~]# docker info
Client:
Debug Mode: false
Server:
Containers: 0
Running: 0
Paused: 0
Stopped: 0
Images: 0
Server Version: 19.03.5
Storage Driver: overlay2
Labels:
Experimental: false
Insecure Registries:
127.0.0.0/8
Live Restore Enabled: false
十一、启动docker
执行命令sudo systemctl start docker
[root@iZbp15rmf8lyj2yhq136ebZ ~]# sudo systemctl start docker
## 或者 执行
[root@iZbp15rmf8lyj2yhq136ebZ ~]# sudo service docker start
#启动docker
[root@iZbp15rmf8lyj2yhq136ebZ ~]# service docker start
#加入开机启动
[root@iZbp15rmf8lyj2yhq136ebZ ~]# chkconfig docker on
ok 到这里安装docker 算是告一段落了，感谢阅读，有任何疑问欢迎评论留言互相交流学习；也欢迎点赞关注和转换，让技术改变生活让我们一起加油😀
