BOSH Links: Why and How

Audience: anyone in the BOSH ecosystem, whether you work on something open-source or proprietary

"BOSH Links" is a feature which simplifies how data is shared between BOSH-deployed jobs that need to collaborate with one another (e.g. a web server and its backing database). Like many BOSH things, the whole "BOSH Links" thing can seem counter-intuitive at first, and it may not be clear why things are the way they are. This note hopes to show some of the powerful benefits of BOSH Links, and provide examples and explanations that make things more intuitive.

1. Why?
2. BASIC: A simple problem statement
3. BASIC: Putting the puzzle pieces together

This will rdp into the private Windows instance at the other end of the ssh tunnel.

DNS Setup for deploying to Pivotal Web Services

The following is a simple guide to using a custom domain when deploying to Pivtoal Web Services (PWS or PDUBS)
You will make use of a wildcard dns CNAME for your own domain that points to a cfapps.io URL.

You will need a permananent cfapps.io URL that becomes the basis for your wildcard CNAME entry.
NEVER REMOVE THIS AS THE WILDCARD DNS WILL FAIL

After that any appname/route will work without any dns entries needed.

Ansible Readme Driven Development (wish)

It would be great to be able to write out a play that contains nothing but name: ... lines as a planning tool.
You can then replace each line one at a time untill you have a working play/role.
