[归档]ubuntu 16.04下安装Docker
Docker在Linux下的安装
归档原因:不再使用ubuntu 16.04.
以 ubuntu 为例,参考官网文档:
https://docs.docker.com/install/linux/docker-ce/ubuntu/
安装准备
看一下自己的Linux机器版本和内核信息:
-
uname --all
Linux skywork 4.15.0-38-generic #41~16.04.1-Ubuntu SMP Wed Oct 10 20:16:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
-
cat /proc/version
Linux version 4.15.0-38-generic (buildd@lcy01-amd64-023) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)) #41~16.04.1-Ubuntu SMP Wed Oct 10 20:16:04 UTC 2018
-
lsb_release -a
No LSB modules are available. Distributor ID: LinuxMint Description: Linux Mint 18.3 Sylvia Release: 18.3 Codename: sylvia
这台机器是Linux Mint 18.3 升级到非常新的Linux内核4.15.0-38了,Linux Mint 18.3 是基于 Ubuntu 16.04,但是有些系统参数不一样,比如这里 Codename 是 sylvia
,而不是 Ubuntu 16.04 的 xenial
。后面安装时要小心,需要修改为 Ubuntu 16.04 的参数。
安装步骤
-
卸载旧版本
sudo apt-get remove docker docker-engine docker.io
-
安装docker
简单起见,使用 docker 仓库安装。
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - # 官方给的是这样,但是`lsb_release -cs`在Linux Mint下取值会不对,因此手工修改 # Linux Mint 18是基于ubuntu 16.04,为 xenial # Linux Mint 19是基于ubuntu 18.04,为 bionic # sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" # for ubuntu 16.04 / linuxmint 18.* sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable" # for ubuntu 18.04 / linuxmint 19.* sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" sudo apt-get update sudo apt-get install docker-ce
如果不想安装最新版本,则可以先查看当前可选版本:
$ apt-cache madison docker-ce docker-ce | 5:18.09.2~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.1~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.0~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.2~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.1~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.0~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.03.1~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
然后执行 :
sudo apt-get install docker-ce=18.06.2~ce~3-0~ubuntu

验证安装
安装完成之后,看一下版本信息:
$ docker version Client: Version: 18.06.1-ce API version: 1.38 Go version: go1.10.3 Git commit: e68fc7a Built: Tue Aug 21 17:24:56 2018 OS/Arch: linux/amd64 Experimental: false Server: Engine: Version: 18.06.1-ce API version: 1.38 (minimum version 1.12) Go version: go1.10.3 Git commit: e68fc7a Built: Tue Aug 21 17:23:21 2018 OS/Arch: linux/amd64 Experimental: false
验证一下:
sudo docker run hello-world
输出如下:
$ sudo docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 78445dd45222: Pull complete Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. ...
-
设置权限避免每次sudo
为了以非root用户使用docker, 可以将用户加入"docker"组.
sudo usermod -aG docker sky
重新登录之后生效。
-
安装 docker client
从下列地址下载到对应的 docker client 安装包:
https://mirrors.ustc.edu.cn/docker-ce/linux/static/stable/x86_64/
tar -zxvf docker-18.09.2.tgz cd docker sudo cp * /usr/local/bin/
