安装Docker

这篇文档介绍如何在VIMs/Edge Ubuntu下安装Docker。

准备

  • Ubuntu V180531或以上版本

安装必要的软件包

khadas@Khadas:~$ sudo apt-get update
khadas@Khadas:~$ sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
khadas@Khadas:~$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

添加Docker源

khadas@Khadas:~$ sudo add-apt-repository \
"deb [arch=arm64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

安装Docker

khadas@Khadas:~$ sudo apt-get update

Ubuntu 16.04:

khadas@Khadas:~$ sudo apt-get install docker-ce=18.03.1~ce-0~ubuntu

Ubuntu 18.04:

khadas@Khadas:~# sudo apt-get install docker-ce=18.03.1~ce~3-0~ubuntu

运行Docker

khadas@Khadas:~$ sudo systemctl enable docker
khadas@Khadas:~$ sudo systemctl start docker

添加Docker组

khadas@Khadas:~$ sudo groupadd docker
khadas@Khadas:~$ sudo usermod -aG docker $USER

NOTE: You need to logout or reboot your system.

检查Docker

khadas@Khadas:~$ docker run hello-world

如果看到如下输出说明Docker安装成功。

khadas@Khadas:~$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
255483503861: 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.
(arm64v8)
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
