Hi folks, I've been trying to come up with a solution to what essentially boils down to this:
Say I'm writing, or simply using, a role which depends on a host var being set for all targeted hosts. An example is ZooKeeper, where each member of an ensemble needs a unique ID configured, and needs to enumerate all the other members in its config file (common for host in groups / hostvars pattern). I'd like to achieve this with an EC2 tag on each host, but say that the role already references a specific hostvar name (which naturally isn't ec2_tag_the_key_name_i_want). Can anyone suggest a programmatic way to map values to a particular host var name during a run? set_fact only appears applicable to the context of a single host as it executes a run (a with_items: groups[foo] loop does not work). I don't particularly want to juggle names in DNS for these hosts in order to use named files in host_vars. Thanks for your help!
