Deploys the CogStack OCR service as a Kubernetes Deployment + Service, with optional HorizontalPodAutoscaler (HPA).

helm install ocr-service ./charts/ocr-service

helm upgrade --install ocr-service ./charts/ocr-service \
  --set envFiles.enabled=true \
  --set-file envFiles.contents[0]=./env/ocr_service.env \
  --set-file envFiles.contents[1]=./env/general.env

Text-only profile (overlay on top of base):

helm upgrade --install ocr-service ./charts/ocr-service \
  --set envFiles.enabled=true \
  --set-file envFiles.contents[0]=./env/ocr_service.env \
  --set-file envFiles.contents[1]=./env/ocr_service_text_only.env \
  --set-file envFiles.contents[2]=./env/general.env

Notes:

• Env files are applied in order; later files override earlier ones.
• Parsed env-file values override values.yaml env keys when envFiles.enabled=true.
• Values are treated as literal strings (shell substitutions like ${VAR:-default} are not expanded by Helm).

helm upgrade ocr-service ./charts/ocr-service

• image.repository / image.tag: container image to run.
• env: OCR service environment variables.
• envFiles.enabled + envFiles.contents: parse one or more .env files at deploy time. Later files override earlier files.
• tmp.*: writable emptyDir mount for /ocr_service/tmp.
• probes.*: startup/readiness/liveness probe settings.
• autoscaling.enabled: enable/disable HPA.

autoscaling:
  enabled: true
  minReplicas: 2
  maxReplicas: 10
  targetCPUUtilizationPercentage: 75
  targetMemoryUtilizationPercentage: 80

HPA requires Kubernetes metrics (usually metrics-server) in the cluster.
