[chef] Chef-server::apache-proxy....

[RUSSELL Scott < >]

Folks,
           Doing something a wee bit unorthodox, but it should work(in my 
world) and it doesn't.  Probably my poor understanding, so appreciate if 
someone could point out the error of my ways...

I have already installed chef-server via apt-get from the opscode-chef repos, 
for ubuntu on 10.10.  All seems well and it works.  Have been deploying in a 
test environment for a few months...

Next I wanted to install apache on the chef-server, and setup some kind of 
proxy so I could connect to the chef server via ssl on port 443.   There is 
some good documentation on how to do this manually on the opscode wiki, but I 
searched around and found essentially what looks like the same thing that has 
been automated as part of the chef-server recipe.   So, I made up a role, and 
added the run list "chef-server::apache-proxy".   Then I run this on the 
chef-server node, by simply assigning the role to the node.  However, I get a 
stack trace, (repeated below).  

From my initial investigations, it looks like I have a very poor 
understanding of just how vhosts are used in the apache2 recipe, and hence am 
struggling to know exaclty where to start looking for the problem.  It seems 
to me to be a problem where I am not specifying the "hostname" of the 
chef-server, but I think if I had an example tutuorial on how to take the 
apache2 recipe, deploy it, then deploy one then two vhosts, then I think my 
understanding would be so much better.    If anyone can help me, I would be 
happy to provide a tutuorial on how to do this, once I have done 
it(chicken/egg).

                      Anyway, thanks for any help you can offer.

                                                      Sc0tt..
