Reserving a floating IP for one or two VSIs sounds easy. But how about for tens of VSIs provisioned in your Virtual Private Cloud (VPC)? Ever thought of auto-assigning a floating IP on-the-fly as and when a new VSI is provisioned in your VPC?
In this post, you will use the IBM Cloud Activity Tracker with LogDNA service to track how users and applications interact with IBM Cloud Virtual Private Cloud (VPC). You will then create a view and an alert on Activity Tracker with LogDNA filtering VSI creation logs. The logs are then passed to IBM Cloud Functions Python action as JSON. The action reserves a floating IP to the newly provisioned VSI (instance) using the instance ID in the passed JSON.
