Hi Jordan,

 

Thanks for your reply.

 

Let’s say the limits are general.

 

Here is what I’ve done:

 

1.       Added depends 'limits'  into “chef-client/metadata.rb”

2.       Where should I put the system-wide limits?

 

# System-wide limits

 

set_limit '*' do

  type 'hard'

  item 'nofile'

  value 4096

  use_system true

end

 

set_limit '*' do

  type 'soft'

  item 'nofile'

  value 1024

  use_system true

end

Mohammad

Hello Mohammad,

 

I went ahead and created an issue https://github.com/jrwesolo/limits/issues/8 so I can add clarification of the usage of this cookbook. This type of cookbook is what is typically called a "Library Cookbook". Check out http://blog.vialstudios.com/the-environment-cookbook-pattern/ and go the section titled "The Library Cookbook". Basically it just provides building blocks for other cookbooks to consume.

 

In order to use this cookbook, add it as a dependency to the cookbook that will need the limits set. For example, you might have an application cookbook that sets up tomcat. This cookbook specifically needs limits changed so you would do two different things:

 

1. Add the dependency on limits to your application tomcat cookbook

2. Add any number of the 'set_limit' definitions (you can also use the LWRP if you'd like)

 

If these limits are general and not needed for any specific application, you can add these definition/resources to your organization's 'base' cookbook.

 

Check out https://github.com/jrwesolo/limits#definition-recommended for the recommended usage. If you'd like to use the LWRP, check out https://github.com/jrwesolo/limits#lwrp. The respective example sections will show you the resources being used and what they would render on the actual file system.

 

Let me know if you have any issues!

 

Sincerely,

Jordan

Mohammad,

 

Fabien is exactly right. This cookbook has no recipes, but instead only provides resources. I can provide a better example once I get to a computer, but for now try what Fabien outlined. The README.md should give a good example on how to use the provided resources.

I'm not familiar with this cookbook and can't look at its inner workings in detail right now, but I see that it has no recipes/ folder, which tells me it just provides resources. It sounds like you added it to your node's run list, but the error you're getting makes sense since the cookbook has no recipes. All you should need to do is add a line like the below to the metadata.rb in your cookbook:

depends 'limits'

Then you will be able to use the things provided by the cookbook.

Hi,

 

Can anybody help me to configure the ‘limits’ cookbook? Installed from https://github.com/jrwesolo/limits.git

 

I added the cookbook to my Chef Server but when I run chef-client on the node I get this error:

----------------------------------------------------------------------------------------------------------------------------------

Recipe Compile Error

================================================================================

 

 

Chef::Exceptions::RecipeNotFound

--------------------------------

could not find recipe default for cookbook limits

----------------------------------------------------------------------------------------------------------------------------------

 

Any idea how to control system limits.conf as well as limits.d configuration files?

 

Regards,

 

Mohammad
