I think it would not be appropriate to invade a recipe’s attributes with
implementation-specific detail such as a list of nodes by IP address and
name for the purpose of updating each node’s /etc/hosts file.
Instead, this information would be a resource stored where? Accessed
from the recipe how?
The specific case to hand is a MongoDB replica set. Each node must know
the hostname of all its sibling replica nodes. If this proves too messy,
I could just use IP addresses when I erect the replica set using the
MongoDB shell.
I’d appreciate a comment or two about this sort of thing, or a link to
some doc. I’ve read Seth Vargo’s post on managing the /etc/hosts file
with Chef, so I know there are cool tools for mucking about with this
file if I need to, I just don’t know where to store the list of IP
addresses-to-names for recipe access.
Many thanks.
