apk安装了一个软件包，但未找到(在Docker上) [英] apk installed a package but its not found (on Docker)

问题描述

我正在使用基于以下内容的docker映像 firesh/nginx-lua 在高山上.

I am using a docker image firesh/nginx-lua which based on alpine.

我按如下所示安装软件包管理器行李箱:

I install the package-manager luarocks as follows:

/bin/luarocks-3.5.0 # apk update
fetch http://mirrors.aliyun.com/alpine/v3.8/main/x86_64/APKINDEX.tar.gz
fetch http://mirrors.aliyun.com/alpine/v3.8/community/x86_64/APKINDEX.tar.gz
v3.8.5-66-gccbd6a8ae7 [http://mirrors.aliyun.com/alpine/v3.8/main]
v3.8.5-66-gccbd6a8ae7 [http://mirrors.aliyun.com/alpine/v3.8/community]
OK: 9564 distinct packages available

/bin/luarocks-3.5.0 # apk add luarocks
OK: 53 MiB in 38 packages

/bin/luarocks-3.5.0 # luarocks
sh: luarocks: not found

您可以看到已经安装了羽绒服，但是当我尝试使用它时却找不到.

As you can see luarocks was installed, but it is not found when I try to use it.

关于如何在此docker上安装luarocks的任何建议?

Any suggestions of how should I install luarocks on this docker?

推荐答案

我认为此图像不适合您要执行的操作.这是启用了LUA(用于nginx)的NginX.该图像不包含任何 lua 开发环境.要用于if lua，请先安装lua

I think this image is not the right thing for what you want to do. This is NginX with LUA (for nginx) enabled. The image doesn't contain any lua development environment. To use if for lua, install lua first

docker run -ti --rm --name test  firesh/nginx-lua  sh                                                                                                                                                / # apk update

在此之后，您将具有 luarocks-5.1 作为命令.如果要在没有 -5.1 的情况下使用它，请使用

after this you will have luarocks-5.1 as a command. If you want to use it without the -5.1 use

/ # alias luarocks=luarocks-5.1
/ # luarocks
Warning: The directory '/root/.cache/luarocks' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing /usr/bin/luarocks-5.1 with sudo, you may want sudo's -H flag.
