Install Litmus ChaosCenter with Ingress
Prerequisites​
Before setting up endpoint with Ingress make sure the Litmus ChaosCenter is installed
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.
- By default, the service type is
NodePort
. For Ingress, we need to change the service type toClusterIP
in the following services.
litmusportal-frontend-service
litmusportal-server-service
- 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"
