Hi all,
I have been avoiding to upgrade Ansible 1.9.4 on Centos 6 for the past few
months, however since the upgrade project is again on my desk, I am
actively working through the warnings and errors e.g. substituting
include: statements in tasks with import_tasks:, editing playbooks and
removing duplicate when: statements and so on.
There is one issue that I cannot resolve, it seems. I maintain a list of
vars for each server in the event that I need to rebuild the server ( NODES
file below ). It essentially is a list of settings for each server like
sshd extra options, interface and cacti settings and so on. The issue is
that in 2.4 I seem not to be able to run this playbook as I was able in
1.9.4. I see that jinja2 in when statement gets a warning.
Any ideas on how I would be able to run this playbook ? I am willing to
redo the nodes file if there is a better way to do this. Looks like jinja2
in when statements is not supported any longer ?
Thank you
