Install Litmus ChaosCenter with Ingress

Prerequisites#

Before setting up endpoint with Ingress make sure the Litmus ChaosCenter is installed in either one of these scopes

Install ChaosCenter with Ingress#

With Litmus-2.0.0, ChaosCenter can be installed with ingress. In the following doc, we will use the Nginx ingress controller for ingress setup.

  1. By default, the service type is NodePort. For Ingress, we need to change the service type to ClusterIP in the following services.
  • litmusportal-frontend-service
  • litmusportal-server-service
  1. Install Nginx Ingress Controller along with Kubernetes RBAC roles and bindings, please refer here
  • Set the environment variable INGRESS as true in the litmusportal-server deployment.

Example:

kubectl set env deployment/litmusportal-server -n litmus --containers="graphql-server" INGRESS="true"
  • If you're changing ingress name from litmus-ingress to a different name, make sure to update the INGRESS_NAME environment variable in the litmusportal-server deployment

Example:

kubectl set env deployment/litmusportal-server -n litmus --containers="graphql-server" INGRESS_NAME="litmus-ingress"
