Working with hostvars across hosts of dynamic inventory

[Joseph Djomeda]

Hello All,

I have been struggling for quite a while now sharing some registered variables during ec2 instances provisioning hosts: localhost with their configuration hosts: tag_Name_tagname of ec2.

Kindly have a look at this sample http://pastie.org/10378851 . In hosts: tag_MName_myappdblivemaster , I need to set the hostname of all the instances created during - name: Launch myapp DB Instances Availability A and - name: Launch myapp DB Instances Availability B.

Because I have not found any way of using the variable myapp_db_ec2_a and myapp_db_ec2_b in the other hosts like tag_MName_myappdblivemaster in particular, I had to break the run, copy the hostnames from the console and paste in in playbook before this can be successful. When I try with hostvars['localhost'] , I get basically nothing to work with.

Is there any thing I am missing or it's not possible?

Best Regards,

Hi,

A registered variable persists only during the play, so maybe you could make them  facts which persists across plays  as below

- set_fact:

     registered_var: "{{ registered_var }}"

and then it shoudl be available via hostvars['localhost']

Hello Benno,

I have tried your suggestion with set_fact but it didn't work. http://pastie.org/10379408 has both the playbook and it's output
