为什么安装了Docker而没有安装Docker Compose?

我已经在CentOS 7上安装了docker，运行如下命令:

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。

然而，当我试图运行docker-compose (docker-compose。yml存在并且有效)它只在CentOS上给了我错误(Windows版本的docker-compose文件工作良好)

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

当前回答

docker-compose目前是一个利用docker(-engine)的工具，但没有包含在docker的发行版中。

以下是安装手册的链接: https://docs.docker.com/compose/install/

TL; diana:

curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/bin/docker-compose

(1.8.0将在未来更改)

其他回答

参考上面给出的答案(我没有足够的声誉单独提到单独的解决方案，因此我在这里集体做这些)，我想补充一些重要的建议:

docker-compose you can install from the repository (if you have this package in the repository, if not you can adding to system a repository with this package) or download binary with use curl - totourial on the official website of the project - src: https://docs.docker.com/compose/install / docker-compose from the repository is in version 1.8.0 (at least at me). This docker-compose version does not support configuration files in version 3. It only has version = <2 support. Inthe official site of the project is a recommendation to use container configuration in version 3 - src: https://docs.docker.com/compose/compose-file / compose-versioning /. From my own experience with work in the docker I recommend using container configurations in version 3 - there are more configuration options to use than in versions <3. If you want to use the configurations configurations in version 3 you have to do update / install docker-compose to the version of at least 1.17 - preferably the latest stable. The official site of the project is toturial how to do this process - src: https://docs.docker.com/compose/install/ when you try to manually remove the old docker-compose binaries, you can have information about the missing file in the default path /usr/local/bin/docker-compose. At my case, docker-compose was in the default path /usr/bin/docker-compose. In this case, I suggest you use the find tool in your system to find binary file docker-compose - example syntax: sudo find / -name 'docker-compose'. It helped me. Thanks to this, I removed the old docker-compose version and added the stable to the system - I use the curl tool to download binary file docker-compose, putting it in the right path and giving it the right permissions - all this process has been described in the posts above.

问候, 亚当

在Linux上，您可以从GitHub上的Compose存储库发布页面下载Docker Compose二进制文件。按照链接中的说明操作，其中包括在终端上运行curl命令来下载二进制文件。这些分步指导也包括在下面。

1:执行此命令下载Docker Compose当前稳定版本:

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

若要安装不同版本的Compose，请将1.26.2替换为您想使用的Compose版本。

2:应用可执行权限的二进制文件:

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

注意:如果安装后命令docker-compose失败，请检查你的路。您还可以创建到/usr/bin或任何的符号链接路径中的其他目录。

只需使用brew:

brew install docker-compose

他们改变了语法。现在它是这样写的:

docker compose [OPTIONS] COMMAND
docker compose ps

现在撰写是插件!但是其他的文档页有旧的语法。我该如何支持兼容性?!

更新: 如果你运行脚本，它可以得到撰写命令:

# docker-compose.sh
if docker compose version > /dev/null ; then
    echo "docker compose"
else
    echo "docker-compose"
fi

# other.sh
DOCKER_C=$($BASEDIR/docker-compose.sh)
echo "docker command is: $DOCKER_C"

生活在拐杖上，感谢Docker命令(:
