Details of installing docker and docker compose instances

1. Uninstall the old version of Docker

sudo yum remove docker docker-common docker-selinux docker-engine

2. Install the dependency package by executing the following command

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

3. In view of domestic network problems, it is strongly recommended to use domestic sources to execute the following command to add yum software sources

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4. Install Docker CE

sudo yum -y install docker-ce

5. Set the boot to start Docker CE

sudo systemctl enable docker

sudo systemctl start docker

6. In view of the domestic network problems, it is slow to pull the Docker image for 10 points. It is strongly recommended to configure the domestic image acceleration after installing Docker

sudo vi /etc/docker/daemon.json

{ "registry-mirrors": ["https://registry.docker-cn.com"]

}

7. Restart takes effect

sudo systemctl daemon-reload

sudo systemctl restart docker

8. Install docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

docker-compose --version
