centos 7安装部署docker

1.centos 7

在windows下通过vm虚拟机安装centos 7：

VMware-workstation-full-10.0.3-1895310

centos 7

2.要求

操作系统的内核版本不能低于3.10

查看内核版本：

# uname -r

3.安装

3.1通过yum安装

需要联入互联网

$ dudo yum update

3.1.2加入yum repo

$ sudo tee /etc/yum.repos.d/docker.repo <<-'EOF'
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=
gpgcheck=
gpgkey=https://yum.dockerproject.org/gpg
EOF

3.1.3安装docker软件包

$ sudo yum install docker-engine

3.1.4启动docker守护进程

$ sudo service docker start

3.1.5验证docker是否安装成功，在容器里面运行一个官方的测试镜像（hello-world）

$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
    latest: Pulling from hello-world
    a8219747be10: Pull complete
    91c95931e552: Already exists
    hello-world:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.
    Digest: sha256:aa03e5d0d5553b4c3473e89c8619cf79df368babd1..1cf5daeb82aab55838d
    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:
     . The Docker client contacted the Docker daemon.
     . The Docker daemon pulled the "hello-world" image from the Docker Hub.
            (Assuming it was not already locally available.)
     . The Docker daemon created a new container from that image which runs the
            executable that produces the output you are currently reading.
     . 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

显示上面的结果则表示安装成功。

3.2用curl工具通过shell脚本安装

$ sudo yum update

3.2.1执行docker安装脚本

$ curl -fsSL https://get.docker.com/ | sh

3.2.2启动docker

$ sudo service docker start

3.2.3验证

$ sudo docker run hello-world
