This commit establishes the foundation for the homelab GitOps repository: - Created layered architecture (infrastructure/platform/apps) - Added MCP servers umbrella chart with SOPS-encrypted secrets - Configured Flux Kustomizations for infrastructure and platform layers - Set up SOPS + Age for secrets management - Added .gitignore and documentation MCP servers include: - Gateway with auth (API keys in encrypted secrets) - n8n MCP (workflow automation) - Playwright MCP (browser automation) - Kubernetes MCP (kubectl operations) - GitHub MCP (repository management) - Gitea MCP (self-hosted git) - SQLite MCP (database operations) - Filesystem MCP (file operations) - Fetch MCP (HTTP requests) - Memory MCP (shared memory/state) All secrets are encrypted with SOPS using Age encryption.
