Hi Everyone,
I'm new to this group so please let me know if I break any etiquette.
I'm wondering if anyone can help with the below issue I am facing.
I am using docker compose to startup prometheus and the blackbox exporter.
I am seeing errors from my prometheus and blackbox docker containers that
indicate I have used an incorrect yml syntax but I'm not clear where I am
going wrong here.
If anyone have any idea where I might be going wrong I greatly appreciate
your input.
Thank you in advance.
Nick
The errors are as follows:
