centos8安裝docker和docker-compose

1. 首先更新一下：yum -y update

2. centos8默認使用podman代替docker，所以需要containerd.io，那我們就安裝一下就好了

   yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm

    

3. 安裝一些其他依賴

   yum install -y yum-utils device-mapper-persistent-data lvm2
   yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
   yum makecache
   

4. 安裝docker-ce

   dnf -y  install docker-ce --nobest

    

5. 開啟Docker服務並設置開機自啟

   systemctl start docker && sudo systemctl enable docker

6. 測試，如輸出下圖結果則安裝成功

   docker version

   

    

    

   Docker-compose 安裝

7. //推薦方法一
   # 方法一 (Refer to: https://docs.docker.com/compose/install/)
   sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   
   sudo chmod +x /usr/local/bin/docker-compose
   
   # 方法二 (Refer to: https://docs.docker.com/compose/install/#install-using-pip)
   sudo pip3 install docker-compose
   
   # 測試, 如輸出下圖結果則安裝成功
   docker-compose --version
   # 輸出：docker-compose version 1.27.4, build xxx
