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

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.

其他回答

我建议在Mac上使用官方pkg。我猜docker-compose默认情况下不再包含在docker中:https://docs.docker.com/toolbox/toolbox_install_mac/

尝试在CentOS上使用curl per docker docs安装docker-compose(适用于Linux)。在这些步骤之后,它返回一个错误

docker-compose -v
/usr/local/bin/docker-compose: line 1: Not: command not found

有趣的是,docker-compose文件在第一行只包含“Not Found”(它应该是二进制文件)

cat /usr/local/bin/docker-compose
Not Found

这意味着我试图从github链接卷曲不存在。我失败的链接是:

sudo curl -L "https://github.com/docker/compose/releases/download/2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

在本地运行uname -s和uname -m可以看到需要添加到下载url中的内容

uname -s
Linux
uname -m
x86_64

在浏览器中尝试url https://github.com/docker/compose/releases/download/2.2.2/docker-compose-linux-x86_64 显示未找到该页面。

一个他们在版本中添加“v”的问题,如v2.2.2。所以下载url应该是v https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64。他们的发布:https://github.com/docker/compose/releases/

这是有效的(注意v2.2.2)

sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v
Docker Compose version v2.2.2

以上的解决方案对我不起作用。但我发现这个很管用:

sudo apt-get update -y && sudo apt-get install -y python3-pip python3-dev
sudo apt-get remove docker docker-engine docker.io
curl -fsSL get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo pip3 install docker-compose
#sudo docker-compose -f docker-compose-profess.yml pull ofw
sudo usermod -a -G docker $USER
sudo reboot

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)

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
