Re: [Fab-user] Best way to sort and maintain a list of server ?

[Kevin Horn]

I had a similar situation once, and what I did was to define a mapping with servers as the keys and a list of groups as the values. e.g.

group_map = {

   'serv1' = ['group1', 'group2'],

   'serv2' = ['group2', group3],

}

Then I wrote a function to "reverse" that mapping (generate the mapping that roledefs expects) and assigned the result to roledefs, e.g.

env.roledefs = map_flipper(group_map)

the definition of map_flipper is left to the reader, but it isn't difficult.

Good luck!

We ended up doing the same thing with boto. That said if you are not using AWS or you can't have an API.

You could do a naming scheme. For example web1,web2,etc. and dweb1,dweb2, etc. as the hostname of the machines. Then have code autogenerate that and only update the list when new machines are added.

After some issues with maintaining lists like that, I decided not to
maintain any. Let me explain... I'm an AWS user, so what I do is to
tag my servers accordingly when they are spawned, and then when I want
to run a command across all my web servers in the production
environment, I simply query the AWS API using boto to retrieve all the
instances which match those tags, get the IP addresses, and then run
the command on them.
