Deployment Notes

This set of YAML files defines Kubernetes resources to deploy an application called alert-manager-to-service-now on OpenShift. The main components are:

  • Namespace: Creates a namespace called alert-manager-to-service-now to deploy resources into.

  • Service: Exposes the application via a ClusterIP service on port 5000.

  • Deployment: Deploys the alert-manager-to-service-now container image built from the Git repository.

  • BuildConfig: Defines a build config to build the container image from the Git repository source code.

  • ImageStream: Tracks built container images.

  • Route: Creates a route to expose the service externally via a hostname.

Configuration

The Deployment defines a few key environment variables:

  • SERVICENOW_INSTANCE_URL: The ServiceNow instance URL to connect to.
  • SERVICE_NOW_USERNAME: Username for authenticating to ServiceNow.
  • SERVICE_NOW_PASSWORD: Password for the ServiceNow user.

These should be configured with the appropriate values for your ServiceNow instance.

The container image is built from the Git repository at https://github.com/tosin2013/alert-manager-to-service-now.git. The BuildConfig watches this repository for changes to trigger new builds.

The Route exposes the service externally via the generated hostname. Traffic is secured with edge TLS termination.
