Hi,
I want to insert an failure on my playbook where if the hostgroup isnt in
the inventory, it fails.
Inventory path is
inventory/"environment_name"/inventory
and looks similiar to this
[NodeGroup1]
node1@node
[NodeGroup2]
node2@node.
node3@node.
When running a playbook using --extra vars and declaring the name of the
host group like so
ansible-playbook deploy_rpm.yml -i environment/testEnv
--extra-vars='{"hostgroup": "NodeGroup1", "var1": "test-rpm", "version":
"0.1"}'
It passes as NodeGroup1 is in the inventory
When the hostgroup is named wrong, 'NodeGroup999' for example.
ansible-playbook deploy_rpm.yml -i environment/testEnv
--extra-vars='{"hostgroup": "NodeGroup999", "var1": "test-rpm", "version":
"0.1"}'
It just silently fails but doesnt return an error message or stop.
I have added this in as a task but it doesnt seem to like it.
- name: "Grep inventory to check hostgroup exists."
fail: msg:="Hostgroup '{{ hostgroup }}' is not defined"
when:
- inventory_hostname in groups['hostgroup']|default([])
How can i improve this task to stop the playbook and return a failure? Is
it best to put the path of the inventory files inside the 'when' part of
the task?
I think you only option is to add the following play on top of your
playbook.
- hosts: localhost
gather_facts: no
become: no
tasks:
- fail:
msg: Hostgroup '{{ hostgroup }}' is not defined
when: hostgroup not in groups
