Step 1: Create a certificate request configuration Create request.json :

kubectl create secret tls myapp-tls --cert=myapp.crt --key=myapp.key kubectl create configmap ca-bundle --from-file=ca.crt Mount in your deployment: vmware vcert tool

# Script: renew.sh vcert renew --cert myapp.crt --key myapp.key --out-dir ./certs kubectl create secret tls myapp-tls --cert=./certs/myapp.crt --key=./certs/myapp.key --dry-run=client -o yaml | kubectl apply -f - Deploy as a Kubernetes CronJob (e.g., run every 5 days for a 7-day cert). In enterprise setups, the VMware CA can forward requests to a Venafi TPP server. vCert transparently supports this. Just set the appropriate policy name: vcert health | Command | Purpose | |---------|---------|

vcert auth login --token $(kubectl get secret my-sa-token -o jsonpath='.data.token' | base64 --decode) Test connectivity: vCert transparently supports this
