ubuntu安装docker

ubuntu安装docker

1.更新系统源

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

2.添加GPG key

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

执行结果为

Executing: /tmp/tmp.Jek7P0R86h/gpg.1.sh --keyserver
hkp://ha.pool.sks-keyservers.net:80
--recv-keys
58118E89F3A912897C070ADBF76221572C52609D
gpg: requesting key 2C52609D from hkp server ha.pool.sks-keyservers.net
gpg: key 2C52609D: public key "Docker Release Tool (releasedocker) " imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

3.根据系统版本找到下面对应的链接,这里使用的是Ubuntu 16.04版本，也就是最后一个

Ubuntu version	Repository
Precise 12.04 (LTS)	deb https://apt.dockerproject.org/repo ubuntu-precise main
Trusty 14.04 (LTS)	deb https://apt.dockerproject.org/repo ubuntu-trusty main
Wily 15.10	deb https://apt.dockerproject.org/repo ubuntu-wily main
Xenial 16.04 (LTS)	deb https://apt.dockerproject.org/repo ubuntu-xenial main

4.将下面命令的repo替换为3中的链接

echo "" | sudo tee /etc/apt/sources.list.d/docker.list

修改为

echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" | sudo tee /etc/apt/sources.list.d/docker.list

5.更新源并进行安装

sudo apt-get update

如果这一步骤很慢，则可以修改第4步骤中的文件内容为阿里镜像的地址

deb http://mirrors.aliyun.com/docker-engine/apt/repo/  ubuntu-xenial main

6.执行下面命令，查看可用版本

apt-cache policy docker-engine

7.安装docker

sudo apt-get install docker-engine

8.启动docker服务

sudo service docker start

9.查看运行状态

sudo service docker status

10.运行hello-world例子

sudo docker run hello-world

这一步的操作首先会去docker官方下载hello-world镜像，然后运行

如果这一步也下载缓慢，则执行下面命令，使用daocloud加速器,然后重启docker

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://6f89f03a.m.daocloud.io

sudo systemctl restart docker.service

11.验证是否成功

ubuntu@ubuntu:/etc/apt$ sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              c54a2cc56cbb        5 months ago        1.848 kB


ubuntu@ubuntu:/etc/apt$ sudo docker ps -al
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
