NGINX Ingress Controller

NGINX Ingress controller works with both NGINX and NGINX Plus and supports the standard Ingress features - content-based routing and TLS/SSL termination.

Configuring the credentials

Configure the credentials in the directory /opt/opsramp/agent/conf/app.d/creds.yaml

nginx-ingress-controller:
- name: nginx-ingress-controller
  user: <username>
  pwd: <Password>
  encoding-type: plain
  labels:
    key1: val1
    key2: val2

Configuring the application

Kubernetes environment

Configure the application in config.yaml

- name: nginx-ingress-controller
  container-checks:
    image-check:
      - nginx-ingress-controller
    port-check:
      - 10254
      - 80

Validate

Go to Resources under the Infrastructure tab to check if your resources are onboarded and the metrics are collected.
