centos 7安裝部署docker

標籤：

1.centos 7

在windows下通過vm虛擬機器安裝centos 7：

VMware-workstation-full-10.0.3-1895310  

centos 7

2.要求

作業系統的核心版本不能低於3.10

查看核心版本：

# uname -r

3.安裝3.1通過yum安裝

需要聯入互連網

$ dudo yum update

3.1.2加入yum repo

$ sudo tee /etc/yum.repos.d/docker.repo <<-‘EOF‘[dockerrepo]name=Docker Repositorybaseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/enabled=1gpgcheck=1gpgkey=https://yum.dockerproject.org/gpgEOF

3.1.3安裝docker軟體包

$ sudo yum install docker-engine

3.1.4啟動docker守護進程

$ sudo service docker start

3.1.5驗證docker是否安裝成功，在容器裡面運行一個官方的測試鏡像（hello-world）

$ sudo docker run hello-worldUnable 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:aa03e5d0d5553b4c3473e89c8619cf79df368babd1.7.1cf5daeb82aab55838d    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:     1. The Docker client contacted the Docker daemon.     2. The Docker daemon pulled the "hello-world" image from the Docker Hub.            (Assuming it was not already locally available.)     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    For more examples and ideas, visit:     http://docs.docker.com/userguide/

顯示上面的結果則表示安裝成功。

3.2用curl工具通過shell指令碼安裝

$ sudo yum update
