[ansible-project] set_fact strange behavior

[Alexander Popov]

- name: crate vpc.
ec2_vpc:
...
register: vpc

- debug: var=vpc.vpc_id

- name: select public vpc
set_fact:
vpc_id: "{{vpc.vpc_id}}"

- debug: var=vpc_id


TASK [setup : setup : crate vpc]
************************************************
ok: [127.0.0.1] => {"changed": false, .... "vpc_id": "vpc-e31c0086"}



TASK [setup : setup : debug var=vpc.vpc_id]
*************************************
ok: [127.0.0.1] => {
"changed": false,


"vpc.vpc_id": "vpc-e31c0086"


}



TASK [setup : setup : select public vpc]
****************************************
ok: [127.0.0.1] => {"ansible_facts": {"vpc_id": "vpc-e31c0086"}, "changed":
false}

TASK [setup : setup : debug var=vpc_id]
*****************************************
ok: [127.0.0.1] => {
"changed": false,


"vpc_id": "VARIABLE IS NOT DEFINED!"


}
