  • centos7.1下 Docker环境搭建

    Docker requires a 64-bit installation regardless of your CentOS version. Also, your kernel must be 3.10 at minimum, which CentOS 7 runs.


    [root@VM_225_102_centos ~]# uname -a
    Linux VM_225_102_centos 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux


    如果系统有网:

    1. Log into your machine as a user with sudo or root privileges.

    2. Make sure your existing yum packages are up-to-date.

    1. $ sudo yum update
      
    2. Run the Docker installation script.

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

      This script adds the docker.repo repository and installs Docker.

    3. Start the Docker daemon.

      $ sudo service docker start
      
    4. Verify docker is installed correctly by running a test image in a container.

      $ sudo docker run hello-world
    Unable to find image 'hello-world:latest' locally
    latest: Pulling from library/hello-world
    c04b14da8d14: Pull complete 
    Digest: sha256:0256e8a36e2070f7bf2d0b0763dbabdd67798512411de4cdcf9431a1feb60fd9
    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.
     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
