Afternoon,
I have a template where I have a group of 4 IPs. I want to make a
list of the 3 IPs - These 3 IPs are for the other database systems,
so need to except the IP of the current database where the template is
being deployed. The line that does this is below, but over the can¹t
seem to get it working despite looking at it for a couple of years
/etc/ansible/roles/mysql/templates/template/galera.cnf.j2
Š.
wsrep_cluster_address=gcomm://{{databases | join(',') | difference
(ansible_ipv4.bond0)}};
Š..
When I run the playbook, it fails with the following error.
fatal: [192.168.149.241] => {'msg': "AnsibleUndefinedVariable: One or
more undefined variables: 'ansible_ipv4' is undefined", 'failed':
True}
fatal: [192.168.149.241] => {'msg': 'One or more items failed.',
'failed': True, 'changed': False, 'results': [{'msg':
"AnsibleUndefinedVariable: One or more undefined variables:
'ansible_ipv4' is undefined", 'failed':
True}]} FATAL: all hosts have already failed ‹ aborting
What would be the appropriate way to use difference filter to achieve
my goal here?
Regards,
William
