- Corrigir tipos Hetzner: CPX não existe, usar CX (Intel shared vCPU) - CX23 (2 vCPU, 4GB) equivalente ao CAX11 - CX33 (4 vCPU, 8GB) equivalente ao CAX21 - CX43 (8 vCPU, 16GB) equivalente ao CAX31 - Corrigir location no autoscaler para amd64 (nbg1→fsn1) - Remover gitlab-pool do autoscaler (substituído pelo Gitea) - Aumentar worker-pool max para 30 - Corrigir Floating IP e Load Balancer hardcoded em nbg1 - Corrigir stdin em read interativo: usar < /dev/tty e read -p - Corrigir cleanup de namespace: lidar com Terminating e finalizers - Corrigir CNPG: nome do deployment, secret e endpointURL duplo - Aulas afetadas: 08, 09, 10, 11, 12, 14, 17

# ── Topology-aware placement ──
|
|
# Hetzner CCM labels nodes automatically:
|
|
# topology.kubernetes.io/zone = fsn1 | nbg1 | hel1 (datacenter)
|
|
# topology.kubernetes.io/region = eu-central | hel-southeast
|
|
#
|
|
# podAntiAffinityType: required → no 2 PG pods on same node (hard constraint)
|
|
# topologyKey: kubernetes.io/hostname → spread across nodes
|
|
#
|
|
# For cross-DC spread, CNPG relies on Kubernetes scheduler topology awareness.
|
|
# With nodes in multiple zones (fsn1, nbg1, hel1), the scheduler naturally
|
|
# spreads pods when combined with the node autoscaler.
