I have a var file with mount points that should be mounted. A common entry
for /home goes on all servers. Some servers (e.g. web and perl) have their
own set of mount points. I'm using Ansible pull and I build the element
dynamically. So for webs, I reach in by using "aws_mounts[nfs_group]", with
"nfs_group" equal to "web_mounts" for web servers and "perl_mounts" for
perl servers. Generating the variable isn't an issue. However, some servers
do not have "nfs_group" defined and the task will fail w/ a "variable is
undefined error"
I tried the following:
# tasks
- name: Create fstab entries
mount:
fstype: nfs
state: mounted
opts: "{{ item.opts }}"
src: "{{ item.source }}"
name: "{{ item.dest }}"
when: item.source is defined
with_items:
- "{{ aws_mounts[nfs_group] | default({}) }}"
- "{{ aws_mounts.common }}"
# vars/main.yml
---
aws_mounts:
common:
- { source: "/home", dest: "/opt/ansible-home",
opts: "bind" }
web_mounts:
- { source: "/tmp", dest: "/opt/ansible-web",
opts: "bind" }
