ubuntu kylin 18.04安装docker笔记

删除原有的docker应用（如果有的话）：

sudo apt-get remove docker docker-engine docker.io

更新一下：

sudo apt-get update

下载支持 https 的相关依赖：

sudo apt-get install \

    apt-transport-https \

    ca-certificates \

    curl \

    software-properties-common

下载docker的官方gpg密钥：

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

添加apt仓库：

sudo add-apt-repository \

   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \

   $(lsb_release -cs) \

   stable"

再更新一下：

sudo apt-get update

下载docker ce版本：

sudo apt-get install docker-ce

为了认证docker安装好了，要记得跑一下hello world程序哦：

sudo docker run hello-world

提示如下信息，说明安装docker成功了：

zifeiy@zifeiy-S1:~$ sudo docker run hello-world

Unable to find image 'hello-world:latest' locally

latest: Pulling from library/hello-world

9db2ca6ccae0: Pull complete

Digest: sha256:4b8ff392a12ed9ea17784bd3c9a8b1fa3299cac44aca35a85c90c5e3c7afacdc

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

Share images, automate workflows, and more with a free Docker ID:
