Part of SOPS multi-user secrets migration.
- .sops.yaml: defines age recipients (Viktor + CI)
- scripts/tg: wrapper that decrypts secrets before running terragrunt
- .gitignore: excludes decrypted secrets.auto.tfvars.json
No functional change — terraform.tfvars still works as before.
Check real CPU/memory usage via kubectl top nodes instead of
limits-vs-allocatable ratios. Thresholds: >80% WARN, >90% FAIL.
Limits overcommit is expected with 70+ services on 3 worker nodes.
- Reduce Kyverno LimitRange default limits ~4x across all tiers to fix
800-900% memory overcommitment on worker nodes
- Add cluster health check #25: per-node resource overcommitment
showing requests and limits vs allocatable capacity
- Add Kyverno policy for Goldilocks VPA mode by tier: tier-0 namespaces
get VPA Off mode (recommend only, no evictions) to prevent downtime
on critical infra (traefik, cloudflared, authentik, technitium, etc.)
- Non-tier-0 namespaces get VPA Auto mode for active right-sizing
Drone CI has been fully replaced by Woodpecker CI at ci.viktorbarzin.me.
Destroys K8s resources (12), removes DNS records, NFS exports, Uptime Kuma
monitor, dashboard entry, and all code/doc references across 18 files.
Generated individual stack directories for all 66 services under stacks/.
Each stack has terragrunt.hcl (depends on platform) and main.tf (thin
wrapper calling existing module). Migrated all 64 active service states
from root terraform.tfstate to individual state files. Root state is now
empty. Verified with terragrunt plan on multiple stacks (no changes).
- Add explicit resource limits to dashy (2Gi memory) to prevent OOMKilled
during webpack build on startup
- Rewrite DNS healthcheck to test from inside the Technitium pod via
kubectl exec, since MetalLB virtual IPs aren't reachable from outside
the L2 network
- Deleted orphaned kured/tls-secret (expired Oct 2025, module disabled,
not mounted by kured DaemonSet)
Adds check #14 that queries Uptime Kuma API for application-level
monitor status, complementing the kubectl-level checks with HTTP/ping
health data. Reports down monitors by name with PASS/WARN/FAIL thresholds.
Replace deprecated wildcard containerd mirror with per-registry
config_path approach. Add proxy containers for ghcr.io, quay.io,
registry.k8s.io, and reg.kyverno.io on the docker-registry VM.
Set static IP for docker-registry VM to avoid DHCP issues.
