How to install Docker and configure Alibaba Cloud Image Accelerator

Docker Installation

There is no need to talk about the installation on Windows system, because Docker is open source, so just go to the official website: https://www.docker.com/ to download the installation package and install it.

In fact, the Linux system installation is also very simple. Just write down the commands given on the official website and the installation will be successful. Then start the service and you can use it. For example, my system is CentOS7, and its installation is as follows:

First, go to the official website of CentOS to install Docker: https://docs.docker.com/engine/install/centos/

I have never installed other versions of Docker, so I don’t need to uninstall the old version of Docker. I can just copy and paste the command to install it according to the first installation method he gave.

Install the yum-utils package, which provides the yum-config-manager program, and creates a stable docker repository

Start the docker repository

Enable the test channel

Disable docker repository

Install the latest version of Docker

Then, start the Docker service

View the Docker installation version command: docker version

At this point, the latest version of Docker has been installed and started successfully

Docker configuration Alibaba Cloud Accelerator image

Because the docker repository: https://hub.docker.com/ is a foreign site, access is very slow, so you can use Alibaba Cloud's mirror repository

Prerequisite: Register an Alibaba Cloud developer account

Go to Alibaba Cloud Container Mirroring Service, click Image Accelerator, and you will get your own image accelerator address. Then, configure it according to your system and follow the operation documentation.

You can execute: cat /etc/docker/daemon.json to check, as shown below, of course, the image address is your own

Of course, if you are really worried, you can use the docker info command to check whether the image repository is an Alibaba Cloud image. This means that there is definitely no problem.

Run the hello-world image

Since I have run it once, I will run it directly this time. The first time I run it, it will prompt that the image cannot be found locally. Then I will go to Alibaba Cloud to download the image and run it again.
