Scale Deployment Replicas

Preconditions

Before applying this skill, verify:

• Resource is a Deployment or StatefulSet
• Target replica count is within configured limits (1-10)
• Current replica count differs from target

Actions

1. Scale the Deployment

Scale the deployment to the target number of replicas.

mcp_tool: kubernetes-mcp-server/resources_scale
params:
  apiVersion: apps/v1
  kind: $resource_kind
  name: $deployment_name
  namespace: $namespace
  scale: $target_replicas
timeout: 60s

Success Criteria

The skill succeeds when:

• Deployment shows target replica count
• All replicas become Ready within 5 minutes

Failure Handling

If scaling fails:

1. Check resource quotas in namespace
2. Verify node capacity
3. Check for PVC binding issues
4. Escalate if pods cannot schedule

Examples

Input Context:

{
  "deployment_name": "api-server",
  "namespace": "production",
  "resource_kind": "Deployment",
  "current_replicas": 2,
  "target_replicas": 5
}

Expected Outcome: Deployment scaled to 5 replicas, all pods Running within 5 minutes.
