'How to configure the cluster to provide signing
I have deployed DigitalOcean Chatwoot. Now I need to add the certificate created in the cluster config so that it can be accessed using HTTPS.
I am following this documentation, to manage TLS Certificates in the Kubernetes Cluster. After following the steps, mentioned in the documentation, I got these
But, as mentioned in the last point of the documentation, I need to add the certificate keys in the Kubernetes controller manager. To do that I used this command
kube-controller-manager --cluster-signing-cert-file ca.pem --cluster-signing-key-file ca-key.pem
But I am getting the below error :
I0422 16:02:37.871541 1032467 serving.go:348] Generated self-signed cert in-memory
W0422 16:02:37.871592 1032467 client_config.go:617] Neither --kubeconfig nor --master was specified. Using the inClusterConfig. This might not work.
W0422 16:02:37.871598 1032467 client_config.go:622] error creating inClusterConfig, falling back to default config: unable to load in-cluster configuration, KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT must be defined
invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable
Can anyone please tell me how can I configure the cluster to provide security (HTTPS), to the cluster?
