为什么安装了 Docker 而不是 Docker Compose? [英] Why is Docker installed but not Docker Compose?

问题描述

我已经通过运行以下命令在 CentOS 7 上安装了 docker，

I have installed docker on CentOS 7 by running following commands,

curl -sSL https://get.docker.com/ | sh
systemctl enable docker && systemctl start docker
docker run hello-world

注意:helloworld 运行正常，没有问题.

但是，当我尝试运行 docker-compose(docker-compose.yml 存在且有效)时，它只会在 CentOS 上给我错误(Windows 版本适用于 docker-compose 文件)

however when I try to run docker-compose (docker-compose.yml exists and valid) it gives me the error on CentOS only (Windows version works fine for the docker-compose file)

/usr/local/bin/docker-compose: line 1: {error:Not Found}: command not found

推荐答案

你还需要安装 Docker Compose.请参阅手册.以下是您需要执行的命令

You also need to install Docker Compose. See the manual. Here are the commands you need to execute

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)"  -o /usr/local/bin/docker-compose
sudo mv /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
