Having worked with CentOS for many years, content may not apply to macOS or Ubuntu users in some cases.

You can refer to the documentation from Tsinghua University for installation guidance: https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/

Installation

Due to unknown mysterious forces, domestic Docker installation is recommended to set the cloud vendor’s repository address. Here we recommend using Alibaba Cloud.

Set Repository Source Address

yum install yum-utils device-mapper-persistent-data lvm2 && \
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

Deploy the Latest Version

Docker is a commonly used background service, we recommend setting it to start on boot. The following command applies to CentOS 7:

sudo yum install -y docker-ce docker-ce-cli containerd.io && systemctl enable --now docker

Deploying a Specific Version

The releases of kubernetes and docker are not fully synchronized. If you need to deploy kubernetes subsequently, refer to the kubernetes deployment instructions and install a specific version of docker.

yum list docker-ce --showduplicates | sort -r
sudo yum install -y docker-ce-18.09.2-3.el7 docker-ce-cli-18.09.2-3.el7 containerd.io-18.09.2-3.el7 && systemctl enable --now docker

Adding Docker Permissions for Regular Users

sudo usermod -aG docker ${USER}

Uninstall

sudo yum erase -y docker-ce docker-ce-cli containerd.io

Mirror Acceleration

There’s still an unknown mysterious force that causes slow image pulls. At this time, domestic cloud vendors have emerged and provided many acceleration services, which are still recommended – Alibaba Cloud.

The acceleration addresses can be managed by you registering an Alibaba Cloud account; this service is free. Alibaba Cloud also offers a free image build service.
