Topology

A page to visually explore relationships between AWS infrastructure and Kubernetes clusters.

Key Features

View Toggle

Switch between two views using the top toggle:

View	Target	Purpose
Infrastructure	AWS Resources	Visualize VPC, EC2, RDS, ELB relationships
Kubernetes	EKS Workloads	Pod, Service, Ingress, Node relationships

Infrastructure View

Two display modes are available:

Map View (Default)

• 5-column layout showing resource hierarchy
• External (IGW/TGW) → VPCs → Subnets → Compute → NAT
• Click/search to highlight related resources

Graph View

• React Flow-based node-edge graph
• Drag nodes to reposition
• Zoom/pan for navigation
• MiniMap for overall structure overview

Kubernetes View

Displays EKS workloads in a 4-column resource map:

Column	Resource	Description
Ingress	K8s Ingress	External traffic entry point
Services	K8s Service	Load balancing, ClusterIP/NodePort/LoadBalancer
Pods	K8s Pod	Running containers
Nodes	EKS Node	Worker nodes (EC2)

Interactive Features

Search

• Infrastructure: Search EC2, Subnet, VPC by name/ID/CIDR
• Kubernetes: Search Pod, Service, Namespace
• Automatically highlights matched and related resources

Click Selection

• Click a resource to select it
• All connected resources are highlighted
• Click again to deselect

Graph View Only

• Mouse wheel: Zoom in/out
• Drag: Pan canvas
• Node drag: Adjust node position
• Controls: Zoom reset, fit to screen
• MiniMap: Overview preview

How to Use

Understand Infrastructure Structure

1. Select Infrastructure view
2. Review hierarchical structure in Map View
3. Follow the VPC → Subnet → EC2 flow
4. Check external connectivity via IGW/TGW

Track Specific Resources

1. Enter resource name/ID in the search bar
2. View highlighted matching resources
3. Related VPC and Subnets are also highlighted
4. Click "Clear search" button to reset

Analyze K8s Traffic Flow

1. Select Kubernetes view
2. Follow the Ingress → Service → Pod → Node flow
3. Click a Service to see connected Pods
4. Search to track specific workloads

Use Graph View

1. Select Graph View in Infrastructure view
2. React Flow graph renders
3. Drag nodes to adjust layout
4. Use MiniMap to view overall structure

Tips

Network Path Tracing

To trace the path from a specific EC2 to the external internet:

1. Enter EC2 name in the search bar
2. Check the highlighted Subnet
3. Verify if Subnet is connected to NAT Gateway or IGW
4. Private Subnet uses NAT, Public Subnet uses IGW path

K8s Service Debugging

Troubleshooting "No Pods connected to Service":

1. Click the Service in Kubernetes view
2. Check connected Pods (0 pods indicates a problem)
3. Verify Pod labels match Service selector
4. If Pods exist, trace to Node to check resource status
