• CERT_FILE=flyte.crt
• CERT_NAME=flyte
• HOST=flyte.local
• openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ${KEY_FILE} -out ${CERT_FILE} -subj "/CN=${HOST}/O=${HOST}" -addext "subjectAltName = DNS:${HOST}"

Create k8s secret

• kubectl create secret tls home --key ${KEY_FILE} --cert ${CERT_FILE} -n flyte

Adjust helm chart

ingress:
  create: true
  host: flyte.local
  ingressClassName: public
  separateGrpcIngress: true
  tls:
    - hosts:
        - flyte.local
      secretName: home
  commonAnnotations:
    kubernetes.io/ingress.class: public

    nginx.ingress.kubernetes.io/app-root: /console
  grpcAnnotations:
    nginx.ingress.kubernetes.io/backend-protocol: GRPC

Running Flyte

run from pi

• kubectl -n flyte port-forward service/flyte-binary-http 8088:8088
• kubectl -n flyte port-forward service/flyte-binary-grpc 8089:8089

running from within LAN

• add 192.168.178.68 flyte.local to /etc/hosts (or configure some local DNS)
• configure ~./flyte/config.yaml

admin:
  endpoint: dns:///flyte.local
  authType: Pkce
  insecure: false
  insecureSkipVerify: false
  caCertFilePath: /Users/janfiedler/Documents/flyte/flyte-on-pi/flyte.local.cer
