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
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。
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
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,
