Fixing an Ansible Lint No-Handler Error in a Multi-Condition Task
You may have a more complicated when condition where it's not obvious on how convert it into a handler. Here's what I did.
Quick Jump: Going Over an Example
I ran across this use case the other day where I had a when ... is changed condition that had an or condition and it wasn’t really clear on how to convert that into a handler.
What I ended up doing was simplifying the condition by performing one of the conditions in the shell script that I was running in the task. After doing that, converting the single when condition into a handler was easy.
Here’s a video walk through of the exact use case and how I fixed it.
