Can you elaborate on what "map values to a particular host var name" would mean? If I may guess at the question, group_vars/<groupname> does in fact work with dynamic groups, if you want everything in ec2_tag_the_key_name_I_want to get a value like x: 42. (set_fact looping over a with_items doesn't allow you to set vars for other hosts, true, it just makes the value of "item" be different in each iteration of the loop is all) Let me know more info and I can perhaps get a bit closer, but I *think* group_vars is what you want. > > Thanks for your help! > > Regards, > Ches > > -- > You received this message because you are subscribed to the Google Groups > "Ansible Project" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to ansible-project+unsubscr...@googlegroups.com. > To post to this group, send email to ansible-project@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/ansible-project/1a3d5eff-6802-4541-98ba-29c42f1f73fd%40googlegroups.com > <https://groups.google.com/d/msgid/ansible-project/1a3d5eff-6802-4541-98ba-29c42f1f73fd%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
