Claude Desktop Session 4 - Infrastructure Automation Context

Mission Overview

Objective: Execute ARM64 CozyStack deployment on AWS with role-based agent delegation Timeline: December 3rd CozySummit demo preparation Context Limit: High efficiency required due to token constraints

Previous Session Analysis

Claude Desktop Strengths Demonstrated ✅

  • Documentation Comprehension: Correctly parsed deployment guides and identified workflow
  • Gap Analysis: Precisely identified critical blockers (VPC IDs, Talos image paths, session tokens)
  • Tool Understanding: Accurately assessed available MCP capabilities
  • Strategic Thinking: Recognized infrastructure → testing → cleanup progression

Identified Blockers from Session 3

  1. VPC/Subnet IDs: Placeholder values need real infrastructure references
  2. Target Region: Alignment between docs (us-west-2) vs AWS MCP default (eu-west-1)
  3. Custom Talos Image: Specific GHCR path for ghcr.io/your-org/talos:v1.10.5-cozy-spin
  4. Bastion Registry Cache: Pre-deployment configuration status
  5. AWS Session Token: MFA refresh required

Role-Based Delegation Strategy

Stakpak Agent Role: Infrastructure Foundation

Strengths: Terraform expertise, cloud resource management, persistent state handling Responsibilities:

  • Update aws-accounts repo Terraform configurations
  • Add bastion host static IP allocation in VPC
  • Configure bastion user-data for OCI registry cache
  • Update security groups for registry cache access (port 5000)
  • Prepare Terraform plan for infrastructure changes
  • Provide real VPC/subnet IDs for Claude Desktop consumption

Stakpak Deliverables:

# Expected outputs for Claude Desktop
terraform plan -out=bastion-updates.tfplan
# Real VPC/subnet IDs in terraform.tfstate
# Bastion host configuration with registry cache
# Security group updates for port 5000 access

Claude Desktop Role: Automation and Deployment

Strengths: AWS API automation, script generation, testing orchestration Responsibilities:

  • Consume infrastructure outputs from Stakpak
  • Execute EC2 instance creation with real VPC parameters
  • Orchestrate boot-to-Talos deployment process
  • Validate cluster deployment and CozyStack installation
  • Execute Crossplane v2 testing workflows
  • Generate cleanup/teardown documentation

Claude Desktop Inputs Required:

# From Stakpak infrastructure work
vpc_id: "vpc-real-id-from-terraform"
subnet_ids:
  control_plane_1: "subnet-real-cp1-id"
  control_plane_2: "subnet-real-cp2-id" 
  worker_subnet: "subnet-real-worker-id"
bastion_ip: "10.0.1.100"  # Static IP from Terraform
registry_cache_endpoint: "10.0.1.100:5000"
region: "us-west-2"  # Aligned with documentation

Infrastructure Prerequisites (Stakpak Tasks)

1. Bastion Host Enhancement

Current State: Basic bastion host in aws-accounts repo Required Updates:

# terraform/bastion.tf updates needed
resource "aws_instance" "bastion" {
  # Add static private IP
  private_ip = "10.0.1.100"
  
  # Enhanced user data for registry cache
  user_data = base64encode(templatefile("${path.module}/bastion-userdata.sh", {
    registry_cache_port = 5000
    ghcr_proxy_config = true
  }))
}

# New security group rules
resource "aws_security_group_rule" "bastion_registry_cache" {
  type              = "ingress"
  from_port         = 5000
  to_port           = 5000
  protocol          = "tcp"
  cidr_blocks       = [var.vpc_cidr]
  security_group_id = aws_security_group.bastion.id
}

2. Registry Cache Configuration

Bastion User Data Script:

#!/bin/bash
# bastion-userdata.sh - OCI pull-through cache setup

# Install Docker
apt-get update
apt-get install -y docker.io

# Configure registry cache for GHCR
mkdir -p /opt/registry-config
cat > /opt/registry-config/config.yml << 'EOF'
version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
proxy:
  remoteurl: https://ghcr.io
  username: ${GHCR_USERNAME}
  password: ${GHCR_TOKEN}
EOF

# Start registry cache
docker run -d \
  --name registry-cache \
  --restart=always \
  -p 5000:5000 \
  -v /opt/registry-config:/etc/docker/registry \
  -v /opt/registry-data:/var/lib/registry \
  registry:2

echo "Registry cache started on port 5000"

3. VPC Parameter Export

Required Terraform Outputs:

# outputs.tf additions
output "cozystack_infrastructure" {
  description = "Infrastructure parameters for CozyStack deployment"
  value = {
    vpc_id = aws_vpc.main.id
    region = var.aws_region
    subnets = {
      control_plane_1 = aws_subnet.control_plane_1.id
      control_plane_2 = aws_subnet.control_plane_2.id
      worker_subnet   = aws_subnet.worker.id
    }
    bastion = {
      instance_id = aws_instance.bastion.id
      private_ip  = aws_instance.bastion.private_ip
      public_ip   = aws_instance.bastion.public_ip
    }
    security_groups = {
      bastion_sg = aws_security_group.bastion.id
    }
  }
}

Claude Desktop Execution Plan

Phase 1: Infrastructure Validation (5 minutes)

  1. Consume Stakpak Outputs: Read infrastructure parameters from Terraform state
  2. Validate Prerequisites: Confirm bastion registry cache operational
  3. Prepare Deployment Manifest: Populate real VPC/subnet IDs in cluster-manifest.yaml

Phase 2: Cluster Deployment (15 minutes)

  1. Execute EC2 Creation: Use AWS MCP to create ARM64 instances
  2. Monitor Boot-to-Talos: Validate Ubuntu → Talos transition
  3. Bootstrap Cluster: Execute talm workflow with CozyStack preset
  4. Validate Installation: Confirm cluster operational status

Phase 3: Testing and Documentation (10 minutes)

  1. Execute Crossplane Tests: Run ARM64 compatibility validation
  2. Document Progress: Generate session summary with status
  3. Prepare Cleanup Script: Ready teardown procedures for post-demo

Critical Success Factors

For Stakpak Infrastructure Work:

  • Bastion host static IP configured
  • Registry cache operational and accessible
  • Real VPC/subnet IDs available for Claude consumption
  • Security groups updated for cluster communication

For Claude Desktop Session:

  • AWS session token refreshed with MFA
  • Infrastructure parameters consumed from Stakpak work
  • Boot-to-Talos process successfully executed
  • Deployment progress documented for teardown

Risk Mitigation

Context Limit Management:

  • Priority 1: Core deployment automation
  • Priority 2: Basic testing validation
  • Priority 3: Comprehensive documentation (if time permits)

Failure Recovery:

  • Stakpak handles infrastructure rollback via Terraform
  • Claude Desktop generates emergency cleanup scripts
  • Manual intervention points clearly documented

Next Session Preparation

Before 4pm Claude Desktop Session:

  1. Stakpak: Complete infrastructure updates and provide parameters
  2. Human: Refresh AWS session token with MFA
  3. Preparation: Stage custom Talos image location details

During Claude Desktop Session:

  1. Infrastructure Validation: Confirm prerequisites met
  2. Deployment Execution: Follow documented automation workflow
  3. Progress Documentation: Generate cleanup and status reports

Success Metrics:

  • ARM64 CozyStack cluster operational
  • Crossplane v2 basic functionality validated
  • Cleanup documentation prepared for post-demo teardown
  • December 3rd demo readiness achieved

Agent Coordination: Stakpak handles persistent infrastructure, Claude Desktop handles ephemeral automation and testing
