Ubuntu Docker 安装

转载于：菜鸟编程

安装方式

自动安装

官方安装脚本自动安装
1.$ curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
使用国内 daocloud 一键安装命令
2.$ curl -sSL https://get.daocloud.io/docker | sh

手动安装

Docker 的旧版本被称为 docker，docker.io 或 docker-engine 。如果已安装，请卸载它们
$ sudo apt-get remove docker docker-engine docker.io containerd runc

更新apt包索引

$ sudo apt-get update

安装apt依赖包

sudo apt-get install

添加 Docker 的官方 GPG 密钥

$ curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

安装 Docker Engine-Community

更新 apt 包索引

$ sudo apt-get update

安装最新版本的 Docker Engine-Community 和 containerd ，或者转到下一步安装特定版本：

$ sudo apt-get install docker-ce docker-ce-cli containerd.io

要安装特定版本的 Docker Engine-Community，请在仓库中列出可用版本，然后选择一种安装。列出您的仓库中可用的版本：

$ apt-cache madison docker-ce
docker-ce | 5:18.09.13-0ubuntu-xenial | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial/stable amd64 Packages
docker-ce | 5:18.09.03-0ubuntu-xenial | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial/stable amd64 Packages
docker-ce | 18.06.1ce3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial/stable amd64 Packages
docker-ce | 18.06.0ce3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial/stable amd64 Packages
...

使用第二列中的版本字符串安装特定版本，例如 5:18.09.13-0ubuntu-xenial。

$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io

测试 Docker 是否安装成功，输入以下指令，打印出以下信息则安装成功:

$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
1b930d010525: Pull complete Digest: sha256:c3b4ada4687bbaa170745b3e4dd8ac3f194ca95b2d0518b417fb47e5879d9b5f
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.
    (amd64)
  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
