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
Version details:
root [/etc/ansible/deployment]# rpm -q ansible
ansible-2.4.1.0-2.el6.noarch
root [/etc/ansible/deployment]# rpm -qa | egrep jinja
python-jinja2-26-2.6-3.el6.noarch
python-jinja2-2.7.2-1.el6.noarch # <— This was needed for filters
root [/etc/ansible/deployment]# rpm -q centos-release
centos-release-6-9.el6.12.3.x86_64
VARS file
hname: “‘{{ inventory_hostname }}’”
hostname_hostname: “{{inventory_hostname}}”
hostname_shortname: “{{inventory_hostname.split(‘.’)[0]}}”
remove dash from host name as Ansible cannot handle it properly in vars
hostname_mounts: “{{hostname_shortname.replace(‘-’,‘’)}}”
hostname_short: “{{hostname_shortname.replace(‘-’,‘’)}}”
