linux下安装与运行docker

写者环境:

1.lsb_release -a

hello@hello:~$ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription: Ubuntu 16.04.3 LTSRelease: 16.04Codename: xenial

2.更新apt和安装gpg秘钥

2.1 sudo apt-get update

2.2 sudo apt-get install apt-transport-https ca-certificates

2.3 sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

3.编辑源文件

sudo vi /etc/apt/source.list.d/docker.list (此文件不存在就直接创建即可)

将文件中的所有内容都删掉,然后写入内容入下:

deb https://apt.dockerproject.org/repo ubuntu-xenial main

4.更新apt包索引

sudo apt-get update

5.安装docker

sudo apt-get install docker-engine

6.启动docker

sudo service docker start

7.验证docker是否正在运行

sudo docker run hello-world

写者运行结果如下:

hello@hello:~$ sudo docker run hello-worldUnable to find image 'hello-world:latest' locallylatest: Pulling from library/hello-worldb04784fba78d: Pull complete Digest: sha256:f3b3b28a45160805bb16542c9531888519430e9e6d6ffc09d72261b0d26ff74fStatus: 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

8.将当前用户加入到docker组

sudo usermod -a -G docker hello

9.重启docker

sudo service docker restart
