在Ubuntu 22.04/Debian 11上安装Docker Compose

更新时间:2023-01-08 10:34:30浏览次数:498+次

如何在Ubuntu 22.04/20.04/18.04、Debian 11/10、CentOS 8、Fedora 37/36/35/34/33/32上安装Docker Compose?本文将向您展示如何在Linux系统上安装最新Docker Compose。其实这篇文章旨在为寻求在Linux上安装Docker Compose的开发人员和SysAdmins提供一个简明的分步指导。我们将检查项目的GithubAPI发布页面,并提取最新的二进制文件。

如何在Linux上安装Docker Compose

您需要在系统上安装curl和wget才能执行此操作。当然,作为具有sudo权限的用户访问终端:

1、CentOS/RHEL

sudo yum -y install curl wget

2、Debian/Ubuntu

sudo apt update

sudo apt install -y curl wget

3、Fedora

sudo dnf -y install curl wget

安装curl后,在Linux机器上下载最新的Compose(Compose是一个用于定义和运行多容器Docker应用程序的工具):

curl -s https://api.github.com/repos/docker/compose/releases/latest | grep browser_download_url  | grep docker-compose-linux-x86_64 | cut -d '"' -f 4 | wget -qi -

使二进制文件可执行:

chmod +x docker-compose-linux-x86_64

将文件移动到PATH:

sudo mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

确认版本:

$ docker-compose version

Docker Compose version v2.14.2

将用户添加到docker组:

sudo usermod -aG docker $USER

newgrp docker

配置Compose命令行完成

Compose具有bash和zsh shell的命令完成功能。

1、对于Bash用户

将完成脚本放在/etc/bash_completion.d/中:

sudo curl -L https://raw.githubusercontent.com/docker/compose/master/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose

源文件或重新登录以享受完成功能:

source /etc/bash_completion.d/docker-compose

2、对于Zsh用户

在~/.zsh/completion/中下载完成脚本:

mkdir -p ~/.zsh/completion

curl -L https://raw.githubusercontent.com/docker/compose/master/contrib/completion/zsh/_docker-compose > ~/.zsh/completion/_docker-compose

通过添加~/.zshrc将目录包含在$fpath中:

fpath=(~/.zsh/completion $fpath)

确保compinit已加载,或者通过添加~/.zshrc来加载:

autoload -Uz compinit && compinit -i

然后重新加载shell:

exec $SHELL -l

测试Docker Compose安装

创建一个测试Docker Compose文件:

vim docker-compose.yml

将以下数据添加到文件中:

version: '3'  

services:

  web:

    image: nginx:latest

    ports:

     - "8080:80"

    links:

     - php

  php:

    image: php:7-fpm

启动服务容器:

$ docker-compose up -d
