CentOS 安裝docker 和 docker-compose

簡介

• 因常會在新機器跑container，藉此紀錄安裝過程，順便寫下腳本安裝懶人包

安裝docker

檢查系統中是否已經安裝了docker

執行：ps -ef |grep docker

如上圖所示，說明系統中並沒有安裝docker

添加docker-ce倉庫

安裝yum倉庫管理工具

sudo yum update -y sudo yum install -y yum-utils

配置docker yum源

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安裝docker engine

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

啟動docker && 設置開機啟動docker

sudo systemctl start docker.service

sudo systemctl enable docker.service

安裝docker-compose

透過curl下載docker-compose

COMPOSE_VERSION=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep 'tag_name' | cut -d\" -f4)



sh -c "curl -L https://github.com/docker/compose/releases/download/${COMPOSE_VERSION}/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose"

將docker-compose變成可執行檔

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

建立連結

ln -s /usr/local/bin/docker-compose docker-compose

確認是否安裝成功

docker-compose -v

腳本自動化安裝docker && docker-compose

#!/bin/bash



# ----- Install docker ----- #



echo "install docker"



sudo yum update -y sudo yum install -y yum-utils 

 

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo



sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin



# start & enable docker.service



sudo systemctl start docker.service

sudo systemctl enable docker.service 



# ----- Install docker-compose ----- #



echo "install docker-compose"



# get latest docker compose released tag



COMPOSE_VERSION=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep 'tag_name' | cut -d\" -f4)



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



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



sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose



# Output compose version



docker-compose --version



exit 0
