# Pre-pull DaemonSet - Alternativa para Cold Start
|
|
# =============================================================================
|
|
# Garante que imagens críticas estejam em cache em TODOS os nodes.
|
|
# Quando KEDA/Cluster Autoscaler criar pods, imagens já estarão disponíveis.
|
|
# =============================================================================
|
|
#
|
|
# COMO USAR:
|
|
# 1. Edite a lista de initContainers com suas imagens
|
|
# 2. kubectl apply -f prepull-daemonset.yaml
|
|
# 3. Aguarde todos os pods ficarem Ready
|
|
# 4. Imagens estarão em cache em todos os nodes
|
|
#
|
|
# QUANDO USAR:
|
|
# - Databases (PostgreSQL, MongoDB) que precisam de 100% dos arquivos
|
|
# - Apps que precarregam (n8n, Laravel Octane)
|
|
# - Qualquer imagem onde eStargz NÃO ajuda
|
|
#
