Walkthrough

Added a new solution document that describes configuring ALB VIP-based health checks for Alauda Container Platform (ACP) clusters, specifying the ALB health-check port (11782), recommended protocol (TCP), timeouts, intervals, unhealthy threshold, and VIP port-forwarding prerequisite.

Poem

I hop to the load balancer, ears up and keen,
Port 11782 gleams like a carrot green.
TCP knocks, quick timeout—two,
Five-second checks keep the burrow true.
Three misses and we hop to fix the scene. 🥕
