已安装Docker但未安装Docker Compose吗?为什么?

我通过运行以下命令在centos 7上安装了docker,

curl -sSL https://get.docker.com/ | sh

systemctl enable docker && systemctl start docker

docker run hello-world

但是,当我尝试运行docker-compose(docker-

compose.yml存在且有效)时,它仅在Centos上给我错误(Windows版本对于docker-compose文件运行良好)

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

回答:

您还需要安装Docker

Compose。请参阅手册。这是您需要执行的命令

sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/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
