我怎样自动加载的软件包（如的libjpeg-dev的）到我的弹性魔豆应用程序？ [英] How do I auto load packages (such as libjpeg-dev) to my Elastic Beanstalk App?

问题描述

我有一个自动缩放运行的Python，我想使用PIL弹性魔豆的应用程序。当我这样做，它说，我的JPEG德codeR失踪，我需要安装的libjpeg。

I have a auto scaling Elastic Beanstalk app running Python where I want to use PIL. When I do, it says that my jpeg decoder is missing and that I need to install libjpeg.

于是我按照AWS官方指导的配置文件的位置：

So I follow AWS official guides for "configuration files" here:

• 的http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html
• <一个href="http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html#customize-containers-format" rel="nofollow">http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html#customize-containers-format

• http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html
• http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html#customize-containers-format

但我无法得到它的工作。

But I can't get it working.

如果我理解正确指导我应该成立一个名为 .ebextensions 在我的应用程序文件夹的目录。在我的.ebextensions我应该成立一个foo.config文件。在我来说，我将其命名为 python.config 。

If I understand the guides correctly I should set up a directory called .ebextensions in my application folder. Inside my .ebextensions I should set up a foo.config file. In my case I name it python.config.

在这个文件中，我假设执行命令。我的config文件的code是：

In this file I'm suppose to execute commands. The code of my .config file is:

packages:
  yum:
    libjpeg-devel: '6b'

我部署我的应用程序，我可以在我的日志快照看到它的膨胀和创建该文件是这样的：

I deploy my app and I can see in my Log Snapshots that its inflating and creating the file like this:

-------------------------------------
/var/log/eb-tools.log
-------------------------------------
creating: /opt/python/ondeck/app/.ebextensions/
inflating: /opt/python/ondeck/app/.ebextensions/python.config  
inflating: /opt/python/ondeck/app/application.py  
...

不过，我无法找到实际执行的命令任何东西。我一直在寻找我的日志荫，python.config，JPEG，libjpeg的等没有任何相关的痕迹。我重新启动应用程序服务器，但我仍然会得到相同的信息，说的libjpeg丢失。

However, I can't find anything about actually executing the commands. I've been searching my log for "yum", "python.config", "jpeg", "libjpeg" and so on without any relevant traces. I restart the application server but still I get the same messages saying libjpeg is missing.

我看到其他人问类似的问题，关于配置文件无法正常工作。但是，我还没有看到任何回答。

I have seen other people asking similar questions, about config files not working. But I have yet to see any answer.

推荐答案

我碰到了同样的问题，而不是建立一个全新的弹性魔豆的应用程序，我通过SSH和重新安装PIL连接到EC2实例（或枕头）。

I ran into the same issue, instead of setting up a completely new Elastic Beanstalk app, I connected to the EC2 instance via SSH and re-installed PIL (or Pillow).

在EC2实例，我运行下面的命令：

On EC2 instance, I ran the following commands:

source /opt/python/run/venv/bin/activate
pip uninstall PIL
pip install PIL

现在PIL支持JPEG编码=）

Now PIL supports jpeg encoding =)
