Hello,
I'm trying to use the setup module with delegation, but I don't understand
one thing. Here is my test playbook :
- hosts: webservers
tasks:
- debug: var=ansible_hostname
- name: Get sql master facts
setup:
delegate_to: "mrk-test-sql1"
register: sql_master_facts
- debug: var=sql_master_facts.ansible_facts.ansible_default_ipv4.address
- debug: var=ansible_hostname
I just want to retrieve the private ip of my master db with Ansible facts
and add it in the /etc/hosts file of my web servers. Here is the output :
PLAY [webservers]
*************************************************************
GATHERING FACTS
***************************************************************
ok: [mrk-test-web1]
ok: [mrk-test-web2]
TASK: [debug var=ansible_hostname]
********************************************
ok: [mrk-test-web1] => {
"ansible_hostname": "mrk-test-web1"
}
ok: [mrk-test-web2] => {
"ansible_hostname": "mrk-test-web2"
}
TASK: [Get sql master facts]
**************************************************
ok: [mrk-test-web2 -> mrk-test-sql1]
ok: [mrk-test-web1 -> mrk-test-sql1]
TASK: [debug var=sql_master_facts.ansible_facts.ansible_default_ipv4.address
] ***
ok: [mrk-test-web1] => {
"sql_master_facts.ansible_facts.ansible_default_ipv4.address":
"10.240.16.26"
}
ok: [mrk-test-web2] => {
"sql_master_facts.ansible_facts.ansible_default_ipv4.address":
"10.240.16.26"
}
TASK: [debug var=ansible_hostname]
********************************************
ok: [mrk-test-web1] => {
"ansible_hostname": "mrk-test-sql1"
}
ok: [mrk-test-web2] => {
"ansible_hostname": "mrk-test-sql1"
}
PLAY RECAP
********************************************************************
mrk-test-web1 : ok=5 changed=0 unreachable=0 failed=0
mrk-test-web2 : ok=5 changed=0 unreachable=0 failed=0
All work, but I don't understand the result of the latest task. Why is it
not like this (like the result of the first task) :
TASK: [debug var=ansible_hostname]
********************************************
ok: [mrk-test-web1] => {
"ansible_hostname": "mrk-test-web1"
}
ok: [mrk-test-web2] => {
"ansible_hostname": "mrk-test-web2"
}
Normally, gathering facts with delegate should not overwrite the current
facts of my web servers ?
My workaround to fix the problem is to recall "setup" for my web server.
Thanks.
Regards,
Antoine Rouaze
