cloudfoundry添加Django的支持-优快云博客

本文详细介绍了如何在Cloudfoundry中为应用添加Django框架支持的过程，包括向Blobstore添加相关包、配置Package、使用Spec文件、更新Yml文件等步骤，并提供了具体代码示例。

本文通过给cloudfoundry添加Django的支持,简要介绍添加Framework的方法.(如何添加Runtime请阅读 http://oldfritters.iteye.com/blog/1867876)

首先,向blobstore中添加Django以及相关的包,方法同前文中添加Python.

其次,添加package

packaging：cf-release/packages/dea_python27/packaging

Packaging代码

spec：cf-release/packages/dea_python27/spec

Spec代码

blob中添加依赖包: cf-release/config/blob.yml

Yml代码

添加runtime支持: cf-release/jobs/cloud_controller/templates/runtimes.yml

Yml代码

添加Django支持: cf-release/jobs/cloud_controller/templates/django.yml

Yml代码

修改代码：cf-release/src/dea/lib/dea/agent.rb

Ruby代码

def stage_app_dir(bits_file, bits_uri, sha1, tgz_file, instance_dir, runtime)
......
FileUtils.rm_f(tgz_file) unless @disable_dir_cleanup
add_runtime_soft_links instance_dir,runtime if runtime['soft_link_tagets'] && runtime['soft_links'] && runtime['soft_link_folder']
bind_local_runtime(instance_dir, runtime)
@logger.debug("Took #{Time.now - start} to stage the app directory")
true
end
#此方法是额外添加的
def add_runtime_soft_links instance_dir, runtime
FileUtils.mkdir_p [instance_dir, runtime['soft_link_folder']].join('/')
runtime['soft_link_targets'].each{|key| FileUtils.ln_s runtime['soft_link_targets'][key], [instance_dir, runtime['soft_links'][key]].join('/') }
end
