Manual installation of docker detailed tutorial

1. Uninstall the old version

The old version of Docker is called docker, docker.io or docker-engine. If they are installed, uninstall them:

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

The current docker package is called Docker Engine-Community, abbreviated as: docker-ce

2. Install using Docker warehouse

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

2.1 Set up the warehouse

Update the apt package index:

sudo apt-get update

Install the apt dependency package to obtain the warehouse via HTTPS:

sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common

Add Docker's official GPG key:

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

sudo apt-key fingerprint 0EBFCD88
输出：
pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <[email protected]>
sub   rsa4096 2017-02-22 [S]

Use the following instructions to set up a stable version of the warehouse:

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

2.2 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, please list the available versions in the repository and choose an installation. List the versions available in your warehouse:

apt-cache madison docker-ce

docker-ce | 5:18.09.1~3-0~ubuntu-xenial | https://mirrors.ustc.edu.cn/docker-ce/linux	/ubuntu  xenial/stable amd64 Packages
docker-ce | 5:18.09.0~3-0~ubuntu-xenial | https://mirrors.ustc.edu.cn/docker-ce/linux/	ubuntu  xenial/stable amd64 Packages
docker-ce | 18.06.1~ce~3-0~ubuntu       | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu  xenial/stable amd64 Packages
docker-ce | 18.06.0~ce~3-0~ubuntu       | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu  xenial/stable amd64 Packages
 ...

Use the version string in the second type to install a specific version, such as 5:18.09.1~3-0ubuntu-xenial:

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 command and print out the following information to install successfully:

sudo docker run hello-world

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

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
