cert-manager

cert-manager is used to obtain TLS certificates from Let's Encrypt.

Added manifest with:

curl -L https://github.com/jetstack/cert-manager/releases/download/v1.15.1/cert-manager.yaml -O

To update certificate issuer

kubectl apply -f cert-manager.yaml
kubectl apply -f issuer.yml
 kubectl -n cert-manager create secret generic tsig-secret \
    --from-literal=TSIG_SECRET=<secret>

Workaround for webhook timeout issue https://github.com/jetstack/cert-manager/issues/2602 It's not very clear why this is happening, deserves further investigation - presumably Calico related somehow:

kubectl delete mutatingwebhookconfiguration.admissionregistration.k8s.io cert-manager-webhook
kubectl delete validatingwebhookconfigurations.admissionregistration.k8s.io cert-manager-webhook
