Dockerizing Compiled Software ┈ Tianon's Ramblings ✿
|
||||
======
|
||||
I recently went through a stint of closing a huge number of issues in the [docker-library/php][1] repository, and one of the oldest (and longest) discussions was related to installing depedencies for a compiling extensions, and I wrote a [semi-long comment][2] explaining how I do this in a general way for any software I wish to Dockerize.
|
||||
|
||||
I'm going to copy most of that comment here and perhaps expand a little bit more in order to have a better/cleaner place to link to!
|
||||
|
||||
The first step I take is to write the naive version of the `Dockerfile`: download the source, run `./configure && make` etc, clean up. I then try building my naive creation, and in doing so hope for an error message. (yes, really!)
|
||||
|
||||
The error message will usually take the form of something like `error: could not find "xyz.h"` or `error: libxyz development headers not found`.
|
||||
|
||||
If I'm building in Debian, I'll hit `https://packages.debian.org/file:xyz.h` (replacing "xyz.h" with the name of the header file from the error message), or even just Google something like "xyz.h debian", to figure out the name of the package I require.
|
||||
|
||||
If I'm building in Alpine, I'll use <https://pkgs.alpinelinux.org/contents> to perform a similar search.
|
||||
|
||||
The same works to some extent for "libxyz development headers", but in my experience Google works better for those since different distributions and projects will call these development packages by different names, so sometimes it's a little harder to figure out exactly which one is the "right" one to install.
|
||||
|
||||
Once I've got a package name, I add that package name to my `Dockerfile`, rinse, and repeat. Eventually, this usually leads to a successful build. Occationally I find that some library either isn't in Debian or Alpine, or isn't new enough, and I've also got to build it from source, but those instances are rare in my own experience - YMMV.
|
||||
|
||||
I'll also often check the source for the Debian (via <https://sources.debian.org>) or Alpine (via <https://git.alpinelinux.org/cgit/aports/tree>) package of the software I'm looking to compile, especially paying attention to `Build-Depends` (ala [`php7.0=7.0.26-1`'s `debian/control` file][3]) and/or `makedepends` (ala [`php7`'s `APKBUILD` file][4]) for package name clues.
|
||||
|
||||
Personally, I find this sort of detective work interesting and rewarding, but I realize I'm probably a bit of a unique creature. Another good technique I use occationally is to determine whether anyone else has already Dockerized the thing I'm trying to, so I can simply learn directly from their `Dockerfile` which packages I'll need to install.
|
||||
|
||||
For the specific case of PHP extensions, there's almost always someone who's already figured out what's necessary for this or that module, and all I have to do is some light detective work to find them.
|
||||
|
||||
Anyways, that's my method! Hope it's helpful, and happy hunting!

Docker 化编译的软件 ┈ Tianon's Ramblings ✿
|
||||
======
|
||||
我最近在 [docker-library/php][1] 仓库中关闭了大量问题，最老的（并且是最长的）讨论之一是关于安装编译扩展的依赖关系，我写了一个[中篇评论][2]解释了我如何用通常的方式为我想要的软件 Docker 化的。
|
||||
|
||||
I'm going to copy most of that comment here and perhaps expand a little bit more in order to have a better/cleaner place to link to!
|
||||
我要在这复制大部分的评论，或许扩展一点点，以便有一个更好的/更干净的链接！
|
||||
|
||||
我第一步是编写 `Dockerfile` 的原始版本：下载源码，运行 `./configure && make` 等，清理。然后我尝试构建我的原始版本，并希望在这过程中看到错误消息。（对真的！）
|
||||
|
||||
错误信息通常以 `error: could not find "xyz.h"` 或 `error: libxyz development headers not found` 的形式出现。
|
||||
|
||||
如果我在 Debian 中构建，我会输入 `https://packages.debian.org/file:xyz.h`（用错误信息中头文件的名称替换 “xyz.h”），或者在谷歌中搜索像 “xyz.h debian” 这样的东西，找出我需要的包的名称。
|
||||
|
||||
如果我在 Alpine 中构建，我将使用 <https://pkgs.alpinelinux.org/contents> 进行类似的搜索。
|
||||
|
||||
“libxyz development headers” 在某种程度上也是一样的，但是根据我的经验，对于这些 Google 对开发者来说效果更好，因为不同的发行版和项目会以不同的名字来调用这些开发包，所以有时候更难确切的知道哪一个是“正确”的。
|
||||
|
||||
当我得到包名后，我将这个包名称添加到我的 `Dockerfile` 中，清理之后，然后重复操作。最终通常会构建成功。偶尔我发现某些库不在 Debian 或 Alpine 中，或者是不够新的，由此我必须从源码构建它，但这些情况在我的经验中很少见 - 因人而异。
|
||||
|
||||
我还会经常查看 Debian（通过 <https://sources.debian.org>）或 Alpine（通过 <https://git.alpinelinux.org/cgit/aports/tree>）我要编译的软件包源码，特别关注 `Build-Depends`（如 [`php7.0=7.0.26-1` 的 `debian/control` 文件][3]）以及/或者 `makedepends` （如 [`php7` 的 `APKBUILD` 文件][4]）用于包名线索。
|
||||
|
||||
就我个人而言，我觉得这种侦探工作很有趣，也很有收获，但我意识到我可能是一个独特的生物。我偶尔使用的另一个技术是看是否有人已经 Docker 化了我想要的东西，这样我可以直接从他们的 `Dockerfile` 中知道我需要安装的东西。
|
||||
|
||||
对于特定的 PHP 扩展，几乎总是有人已经想出对于这个或那个模块需要的依赖，而我所要做的就是做一些轻量的工作找出它们。
|
||||
|
||||
不管怎样，这就是我的方法！希望这个有帮助，玩得愉快！
