# Instala/Atualiza o NGINX Ingress Controller com LoadBalancer Hetzner
|
|
# =============================================================================
|
|
#
|
|
# Este script configura o NGINX Ingress para:
|
|
# - Usar LoadBalancer da Hetzner (requer CCM instalado)
|
|
# - Suportar TCP passthrough para SSH do Gitea
|
|
# - Comunicação via rede privada
|
|
#
|
|
# Pré-requisitos:
|
|
# - Cluster Kubernetes rodando
|
|
# - Hetzner CCM instalado (./install-ccm.sh)
|
|
# - Helm 3.x instalado
|
|
#
|
|
# Uso:
|
|
# ./install-nginx-ingress.sh
