Changing variable value based on another variable value

[Yehuda Pinhas]

Hi guys!

This is my code:

---

  qos_policy: qos-nested-new-10m

   when: "{{ bandwidth_mb }} == '10'"

  qos_policy: qos-nested-new-20m

   when: "{{ bandwidth_mb }} == '20'"

#### Modify: ####

  bandwidth_mb: 10

I'm trying to create a condition for the qos_policy variable:

if bandwidth_mb = 10 then qos_policy = qos-nested-new-10m

if bandwidth_mb = 20 then qos_policy = qos-nested-new-20m

Just for clarification:

• bandwidth_mb & qos_policy are variables

• qos-nested-new-10m & qos-nested-new-20m are strings

The errors im receiving on all my previous attempts to do this code are:

1. invalid syntax

2. duplicate value for qos_policy applying only the last value (always qos-nested-new-20m)

I receive these errors seperatly, depending on how I change the code but its still not working like it should.

What am I doing wrong here?

Thanks in advance,

YP

Concatenate the strings. For example

- hosts: localhost
vars:
bandwidth_mb: 10
tasks:
- set_fact:
qos_policy: "{{ 'qos-nested-new-' +
bandwidth_mb|string +
'm' }}"
- debug:
var: qos_policy

gives

ok: [localhost] => {
"qos_policy": "qos-nested-new-10m"
}

The conditions are expanded by default. Try

- debug:
msg: Bandwidth is 10 MB
when: bandwidth_mb == 10
