2.4. Debian Docker installation

Docker supports the following Debian versions:

Buster 10
Stretch 9 (stable) / Raspbian Stretch

Docker Engine-Community is supported on x86 / 64 (or amd64) armhf, and arm64 architecture.

2.4.1. Use the official installation script to install automatically ¶

The installation commands are as follows:

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

You can also use the domestic daocloud one-click installation command:

curl -sSL https://get.daocloud.io/docker | sh

2.4.2. Manual installation ¶

Uninstall the old version ¶

Older versions of Docker are called docker,docker.io or docker-engine. If you have installed them, uninstall them:

$ sudo apt-get remove docker docker-engine docker.io containerd runc

Install Docker Engine-Community ¶

Use the Docker repository for installation ¶

Before installing Docker Engine-Community on the new host for the first time, you need to set up the Docker repository. You can then install and update Docker from the repository.

Raspbian users cannot use this method!

For Raspbian, the use of a repository for installation is not yet supported. You must use shell scripting instead.

Set up the warehouse ¶

Update the apt package index.

$ sudo apt-get update

Install the apt dependency package, which is used to obtain the repository through HTTPS.

$ sudo apt-get install \\
    apt-transport-https \\
    ca-certificates \\
    curl \\
    gnupg2 \\
    software-properties-common

Add the official GPG key for Docker:

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

9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 verifies that you now have a key with a fingerprint by searching for the last 8 characters of the fingerprint.

$ sudo apt-key fingerprint 0EBFCD88
pub   4096R/0EBFCD88 2017-02-22
      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF
CD88
uid                  Docker Release (CE deb) <docker@docker.com>
sub   4096R/F273FCD8 2017-02-22

Use the following instructions to set up the stable version repository:

$ sudo add-apt-repository \\
   "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/debian
\\
   $(lsb_release -cs) \\
   stable"

2.4.3. Install Docker Engine-Community ¶

Update the apt package index:

$ sudo apt-get update

Install the latest version of Docker Engine-Community and containerd, or go to the next step to install a specific version:

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

To install a specific version of Docker Engine-Community, list the available versions in the repository, and then select an installation. List the versions available in your warehouse:

$ apt-cache madison docker-ce
  docker-ce \| 5:18.09.1~3-0~debian-stretch \|
https://mirrors.ustc.edu.cn/docker-ce/linux/debian stretch/stable amd64
Packages
  docker-ce \| 5:18.09.0~3-0~debian-stretch \|
https://mirrors.ustc.edu.cn/docker-ce/linux/debian stretch/stable amd64
Packages
  docker-ce \| 18.06.1~ce~3-0~debian        \|
https://mirrors.ustc.edu.cn/docker-ce/linux/debian stretch/stable amd64
Packages
  docker-ce \| 18.06.0~ce~3-0~debian        \|
https://mirrors.ustc.edu.cn/docker-ce/linux/debian stretch/stable amd64
Packages
  ...

Install a specific version using the version string in the second column, for example, 5 0~debian-stretch 18.09.1 version 3-version.

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

To test whether Docker is installed successfully, enter the following instructions and print out the following information for successful installation:

$ 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

2.4.4. Uninstall docker ¶

Delete the installation package:

sudo apt-get purge docker-ce

Delete images, containers, configuration files, etc.:

sudo rm -rf /var/lib/docker
