每当AWS上的宝石opsworks [英] Whenever gem on aws opsworks

问题描述

有人在aws opsworks上使用everyth gem有经验/成功吗?有什么好食谱吗?我可以将该配方放在单独的层上，然后将一个实例与该另外的层相关联吗?还是有更好的方法呢?谢谢!!!

Does anyone have experience/success using the whenever gem on aws opsworks? Is there a good recipe? Can I put that recipe on a separate layer and associate one instance with that additional layer? Or is there a better way to do it? Thanks!!!

我们最终做了一些不同的事情...

We ended up doing it a bit differently...

代码:

不能真正发布真实的代码，但这是这样的:

Can’t really post the real code, but it’s like this:

在deploy/before_migrate.rb中:

in deploy/before_migrate.rb:

[:schedule].each do |config_name|
  Chef::Log.info("Processing config for #{config_name}")
  begin
    template "#{release_path}/config/#{config_name}.rb" do |_config_file|
      variables(
        config_name => node[:deploy][:APP_NAME][:config_files][config_name]
      )
      local true
      source "#{release_path}/config/#{config_name}.rb.erb"
    end
  rescue => e
    Chef::Log.error e
    raise "Error processing config for #{config_name}: #{e}"
  end
end

在deploy/after_restart.rb中:

in deploy/after_restart.rb:

execute 'start whenever' do
  cwd release_path
  user node[:deploy][:APP_NAME][:user] || 'deploy'
  command 'bundle exec whenever -i APP_NAME'
end

在config/schedule.rb.erb中:

in config/schedule.rb.erb:

 <% schedule = @schedule || {} %>

set :job_template, "bash -l -c 'export PATH=/usr/local/bin:${PATH} && :job'"
job_type :runner,  'cd :path && bundle exec rails runner -e :environment ":task" :output'
job_type :five_runner, 'cd :path && timeout 300 bundle exec rails runner -e :environment ":task" :output'
set :output, 'log/five_minute_job.log' 
every 5.minutes, at: <%= schedule[:five_minute_job_minute] || 0 %> do
  five_runner 'Model.method'
end

推荐答案

我们在回购协议中有一个随时使用的食谱，我们非常欢迎您在这里使用:https://github.com/freerunningtech/frt-opsworks-cookbooks .我认为您熟悉将自定义食谱添加到opsworks堆栈中的情况.

We have a whenever cookbook in our repo we use that you would be more than welcome to use here: https://github.com/freerunningtech/frt-opsworks-cookbooks. I assume you're familiar with adding custom cookbooks to your opsworks stacks.

我们通常在它自己的层上运行它，其中还包括应用程序部署(而不是应用程序服务器)所需的rails食谱:

We generally run it on its own layer that also includes the rails cookbooks required for application deployment (while not the app server):

• 配置:rails :: configure
• 部署:每当部署
:: rails
• 取消部署:deploy :: rails-undeploy

• Configure: rails::configure
• Deploy: deploy::rails whenever
• Undeploy: deploy::rails-undeploy

但是，我们通常也将此实例部署为应用程序服务器，这意味着我们也确实会在任何时候都从所使用的框中提供请求.

However, we usually also deploy this instance as an application server, meaning we do end up serving requests from the box we're using for whenever as well.

有一个陷阱"，因为您必须在schedule.rb顶部的环境中设置路径，如下所示:

There is one "gotcha", in that you must set your path in the env at the top of the schedule.rb like this:

env :PATH, ENV['PATH']
