[chef] RE: Re: Re: Bootstrapping a lot of nodes

Hi all,

For what it's worth, I've done some work like this using cloud-init and handing each node a shell script that has what run-list and other parameters I want for each node. You can take your pseudocode for such a script directly from knife's bootstrap steps if you like.

Cheers,

who triggers chef-initstrap ? how you spawn a cluster of say 10 nodes? what if some them requires different runlist, currently its hard coded in your script.

I think the best way to accomplish this is to trigger the bootstrap from the node itself, rather than spawn off a ton of knife commands en masse.  chef-client 11.12.x supports the -r parameter, which allows you to specify the run list.

I achieve this in my projects by creating a template that has an init script that triggers the chef-client run.  A gist of what I use is at https://github.com/ameir/chef-initstrap if you want to adapt it for your needs.  It's been working well for us thus far.

Thanks,

Ameir

Hi,

  We have a requirement soon to add  several hundred nodes to our OpenSource Chef server. My question is: does anyone know a good way to handle this?

  I’ve googled quite a lot and cannot find much info about do a ‘mass bootstrapping’.

I will have a list of Environments and the nodes contained within those environments, and I suspect with a little ruby code I could get a script together to parse a file containing this information and bootstrap nodes appropriately, but this seems a little inelegant.

  Are there tools out there to help? Anyone devise a good method to do this?

 

Thanks

Chris
