厨师：Opsworks：运行Rake任务

mconlin 发表于 Dev

我的目标是对在Opsworks中运行的应用执行rake任务。
在我看来，我的opsworks食谱没有从正确的目录运行rake。

如何告诉菜谱在应用主目录中运行（以便它可以提取Gemfile）？
我需要指定RAILS_ENV吗？

我的菜谱default.rb：

Chef::Log.info("****** Audit Photo URLS : Running Rake Task ******")
execute "rake audit:audi_image_urls" do
    command "bundle exec rake audit:audi_image_urls"
end

Opsworks日志中的错误：

该execute资源可以具有从其运行命令的工作目录的cwd属性。

execute "rake audit:audi_image_urls" do
  command       "bundle exec rake audit:audi_image_urls"
  cwd           '/over/there'
  environment   'RAILS_ENV' => 'production'
end

OpsWorks部署事件和执行配方命令

厨师11

OpsWorks填充node[:deploy]['appshortname']用于部署事件和执行食谱堆栈命令容纳每个应用程序的配置。有了这些数据，您可以使用：

execute "rake audit:audi_image_urls" do
  command       "bundle exec rake audit:audi_image_urls"
  cwd           node[:deploy]['appshortname'][:deploy_to]
  user          node[:deploy]['appshortname'][:user]
  group         node[:deploy]['appshortname'][:group]
  environment(  { 'RAILS_ENV' => node[:deploy]['appshortname'][:rails_env] } )
end

如果您在此处配置了任何相关内容:environment_variables，environment则可能需要采购。

从AWS Stack设置docco

在Chef 12 Linux中，堆栈设置可作为Chef数据包使用，并且只能通过Chef搜索来访问。数据袋存储在目录中的一组JSON文件中的AWS OpsWorks Stacks实例上/var/chef/runs/run-ID/data_bags，其中run-ID是AWS OpsWorks Stacks分配给在实例上运行的每个Chef的唯一ID。堆栈设置不再可用作Chef属性，因此无法再通过Chef节点对象访问堆栈设置。有关更多信息，请参阅AWS OpsWorks Stacks数据袋参考。

app = search("aws_opsworks_app").first

execute "rake audit:audi_image_urls" do
  command       "bundle exec rake audit:audi_image_urls"
  cwd           app['app_source']['deploy_to']
  user          app['app_source']['user']
  group         app['app_source']['group']
  environment(  { 'RAILS_ENV' => app['app_source']['rails_env'] } )
end
