Docker安装

一、配置仓库

[root@redhat01 ~]# mount /dev/sr0 /mnt/
mount: /mnt: WARNING: source write-protected, mounted read-only.
[root@redhat01 ~]# vi /etc/yum.repos.d/local.repo
[root@redhat01 ~]# cat /etc/yum.repos.d/local.repo 
[AppStream]
name=AppStream
baseurl=file:///mnt/AppStream
enabled=1
gpgcheck=0
[BaseOS]
name=BaseOS
baseurl=file:///mnt/BaseOS
enabled=1
gpgcheck=0
[root@redhat01 ~]# dnf clean all
13 个文件已删除
[root@redhat01 ~]# dnf makecache
AppStream                102 MB/s | 6.5 MB     00:00    
BaseOS                    40 MB/s | 2.0 MB     00:00

元数据缓存已建立。
[root@redhat01 ~]# 

二、使用yum安装软件包

[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2

三、添加软件源信息

[root@localhost ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

四、更新并安装Docker-CE

[root@localhost ~]# sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
[root@localhost ~]# yum makecache fast
[root@localhost ~]# yum -y install docker-ce

五、开启Docker服务

[root@localhost ~]# service docker start
Redirecting to /bin/systemctl start docker.service
[root@localhost ~]# systemctl status docker
[root@localhost ~]# systemctl enable --now docker

六、配置镜像加速器，让其运行

[root@localhost ~]# mkdir -p /etc/docker
[root@localhost ~]# vi /etc/docker/daemon.josn
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
[root@localhost ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c1ec31eb5944: Pull complete 
Digest: sha256:91fb4b041da273d5a3273b6d587d62d518300a6ad268b28628f74997b93171b2
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
