In K8s, HOSTNAME is set to the pod name, so the server only listened on that interface. The PTY server's loopback fetch to 127.0.0.1 was connection-refused. Always bind to 0.0.0.0 so loopback works.
Homelab
Monorepo for self-hosted applications running on a k3s cluster across Intel NUC machines.
What's Inside
- Apps: Next.js frontend, Express API (TypeScript)
- Infrastructure: Ansible provisioning, ArgoCD GitOps, full Kubernetes platform
- Observability: Prometheus, Grafana, Loki
Prerequisites
Quick Start
# Install dependencies
pnpm install
# Start development
task dev
# Build all apps
task build
Bootstrap Cluster (Day 1)
- Flash Ubuntu Server 24.04 on NUCs, configure SSH access
- Configure Ubiquiti Cloud Gateway (see
infra/ubiquiti/) - Provision nodes and install k3s:
task cluster:bootstrap task cluster:kubeconfig - Install platform components:
task platform:install - Seal initial secrets:
task secrets:seal - Push an app — ArgoCD handles the rest
Branch Deploys
Push a branch or open a PR → GitHub Actions builds changed apps → ArgoCD creates a preview namespace → merge to main deploys to production.
