Fw: "ansible_group_priority" option seems to be ignoring me

[Tomàs Núñez]

Hi
I'm trying to change the order in which our group_vars are loaded with ansible_group_priority but it's not working.

I have a role at roles/mytest/tasks/main.yaml like this:
_______________
- debug: var="myvar"
_______________

Then I have two group_vars files, one called inventory/group_vars/cluster_1.yaml with this values:
________________
ansible_group_priority: 10
myvar: cluster
________________

And another one called inventory/group_vars/role_1.yaml with this value:
________________
myvar: role
________________

Finally I have a playbook called mytest.yaml like this:
________________
- hosts: role_1&cluster_1
roles:
- mytest
________________

I think I'm reproducing exactly the example at https://docs.ansible.com/ansible/devel/user_guide/intro_inventory.html#how-variables-are-merged​ but the result is always "myvar: role". And of course, when I comment that line at role_1.yaml, the result is "myvar: cluster".

I've tried setting ansible_group_priority at role_1.yaml to 9 (and to 11, just in case), but it still happens the same. Well I think at this point I've tried all combinations :D

I'm using ansible version 2.4.0.0 but I also tried with 2.4.2.0 with the same results.

Can anyone spot anything that I'm doing wrong or did I just hit a bug?

You cannot set group priority in group_vars files as it handles the
priority in which group_vars files are read, you need to set it in the
main inventory source.

I tried, but it's not working either. ​I just made a mini-version of our inventory script, adding the ansible_group_priority:
____________________
#!/bin/bash
cat << EOF
{
"cluster_1": {
"hosts": [
"host1"
],
"ansible_group_priority": 10
},
"role_1": {
"hosts": [
"host1",
"host2",
"host3",
],
"ansible_group_priority": 1
}
}
EOF​
_____________________

And when running my playbook I get:
_____________________
TASK [mytest : debug] *********************************************************
ok: [host1] => {
"myvar": "role"
}
_____________________

Just as a refresher, the contents of the playbook are:
_____________________
- hosts: role_1:&cluster_1
roles:
- { role: mytest, tags: mytest }
_____________________

Contents of inventory/group_vars/cluster_1.yaml:
________________
myvar: cluster
________________

And contents of inventory/group_vars/role_1.yaml:
________________
myvar: role
________________

I must be doing something wrong, because being ansible_group_priority higher for cluster, it should show "cluster", but it shows "role".

I tried setting the number 10between quotes and without them with the same result. Also tried removing priority from role (default value should be 1) with the same result.

Any ideas?

I found the problem, I wasn't putting the priority inside "vars". The inventory that works is this one:
______________

#!/bin/bash
cat << EOF
{
"cluster_1": {
"hosts": [
"host1"
],

"vars": {

"ansible_group_priority": 10
}
},
"role_1": {
"hosts": [
"host1",
"host2",
"host3",
],

"vars": {
"ansible_group_priority": 1
}
}
}
EOF
______________

This returns "role" when running the playbook, as I was expecting.

Thanks a lot!!!
