instance-manager always creates normal EC2 instances regardless of the spotPrice value about instance-manager HOT 3 OPEN

Can you check if the LaunchConfig/LaunchTemplate created by the instance-manager? Does it show the spot price being set?

There might be a problem the with setting of lifecycle=spot in this case. I think the current logic depends on whether a spot price is set or not, and not whether instances are actually switched to spot.
In the case of using spot recommendations with minion manager that works fine since the price is available, but if someone just sets a spotPrice which is not available the result would be lifecycle=spot and it cannot switch because the price is not available.

My recommendation for now is to either use spot recommendations via minion-manager or switch to spot via LaunchTemplate/Mixed Instance Policies which is a more automated mechanism via AWS.

Leaving this ticket open so we can look into better logic around manually setting spotPrice

Thank you guys for your thoughts!
Yes, it worked with MixedInstancePolicies or with minion-manager but was curious if it is expected to work for spotPrice.
I'll gladly collaborate and help in introducing a better logic here (or at least fixing the documentation explaining the desired logic).
