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

如果你用的是ubuntu, docker compose可以工作，但docker-compose不行，你需要旧的docker-compose语法可用(可能第三方库使用它)，你可以通过以下步骤修复它:

docker-compose插件可能安装在/usr/libexec/docker/cli-plugins/docker-compose(确保它是)

创建一个符号链接到它:

sudo ln -s /usr/libexec/docker/cli-plugins/docker-compose /usr/bin/docker-compose

现在docker-compose应该可用了

更新:

如果docker-compose在上述路径中找不到，您可以从您的操作系统的发布页面手动下载它，然后移动下载的文件并使其可执行。

cd ~/Downloads
sudo mv ./docker-compose-* /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

其他回答

在Amazon Linux中，如果您将使用哪个docker-compose

您将得到以下错误

[root@ip bin]#哪个docker-compose

no docker-compose in (/sbin:/bin:/usr/sbin:/usr/bin)

只需mv docker-compose从/usr/local/bin到/usr/bin

[root@ip bin]# mv docker-compose /usr/bin

[root@ip bin]#哪个docker-compose

/ bin / sh docker-compose

[root@ip-172-31-36-121 bin]# docker-compose——version

Docker-compose版本1.29.2，构建未知

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.

如果你通过将docker的官方存储库添加到存储库列表来安装docker，如下所示:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

只做:

$ sudo apt-get install docker-compose

对于基于RHEL的发行版/ Fedora:

$ sudo dnf install docker-compose

我在debian上，我发现了一些很自然的事情:

apt-get install docker-compose

它做到了 (未测试centos)
