[chef] Re: Re: Re: chef node and client creation

[Cassiano Leal < >]

A node created in such manner will not have IP address or FQDN because it’s nothing more than on object on the Chef Server. It doesn’t relate to an actual node. Maybe someone else on this list will correct me, but this is my limited understanding.

I haven’t as of yet found an use for manual node creation. Usually I use knife bootstrap or knife ec2, as these will automatically create both the node and client on the chef server, as long as your knife is correctly configured to point to your validation key.

That’s how I work personally. Others may have approaches more similar to what you’re trying to accomplish.

Cheers,

Thank you for explaining it in detail. That was helpful. 

I was able to use knife bootstrap command, but I am finding node/client creation by hand extremely confusing.

For example, a node created with 'knife node create test1' command doesn't have an IP address or FQDN attributes. I am not sure how to add/edit them as well.

$ knife search node name:test1

1 items found

Node Name:   test1

Environment: _default

FQDN:        

IP:

May be it's not a recommended approach, but my plan was use node/client commands to add node/client to the server.

It actually is working.

The fact that ‘knife node show test1’ returns something is proof of that.

The search didn’t work because that query ‘test1’ doesn’t return anything. The basic syntax for these queries is ‘<attribute>:<value>’, such as ‘chef_environment:_default’, or ‘name:test1’. [0]

As for the difference between client and node, that’s a very common doubt for who’s only just starting with Chef. Basically, a client is an entity that can talk to the Chef Server API — It could be a person with certs for querying the API like you’re doing when using knife, or it could be a node.

A node is the actual thing you’re configuring — usually a physical server, a VM or your workstation. It has a run list, a set of attributes, etc, and it belongs to an environment. [1]

The node needs a corresponding client in order to query the Chef Server so that it knows what to do.

The documentation over at http://docs.opscode.com is quite good, be sure to read through as much as you can.

I am looking for documentation on chef client and node objects. I created a node as follows, but it doesn't show up in the search.

$ :~/chef-repo$ knife node create test1

Created node[test1]

How can I get it working to run some recipes?  

Also, what's the relationship between a client and node? How can a client be associated with a node?
