Hello,
I would like to set a lot of parameters when playing my playbook,
depending on the server/user where it will be deployed so the idea is to
set it in the hosts file.
It doesn't seem to work as my varaibles are no set, here is what I plan
to do:
[webserver]
linuxserv ansible_connection=local ansible_user=aa12
extra-vars="@/home/root/vars/vars.json"
running the playbook this way:
ansible-playbook deploy.yml
and with vars.json:
{
"ENVT": "aa12",
"MODULE": "tomweb",
"RELEASE": "1.2",
}
Is this possible or do I have to try to load the vars parameter file in
the playbook ?
If the variables are host specific as you first indicate, you can use
host variables or group variables
You need to have the specific directory structure :
- hosts (file)
- host_vars/ (directory)
- group_vars/ (directory)
$ cat hosts
[webserver]
linuxserv
$ cat host_vars/linuxserv
---
ansible_connection: local
ansible_user: aa12
ENVT: aa12
MODULE: tomweb
RELEASE: 1.2
$ cat group_vars/webserver
---
webserver: apache
Now you run the playbook with those hosts and the variables will be
usable from each hosts
You can actually have different inventory names and different actual
names using this
You can group hosts and use group_vars directory
The host file is an ini file (or executable), while the host and group
vars file are json/yaml files (that is why they have the three dashes)
For more info look at the documentation, it is very clearly explained :
