Create db-cert bundle

Create db cert bundle if it does not exists as follows:

cat <<EOF | kubectl apply -f -
apiVersion: trust.cert-manager.io/v1alpha1
kind: Bundle
metadata:
  name: db-cert
spec:
  sources:
  - secret:
      name: "postgresql-netbackup-ca"
      key: "tls.crt"
  target:
    namespaceSelector:
      matchLabels:
        kubernetes.io/metadata.name: "$ENVIRONMENT_NAMESPACE"
    configMap:
      key: "dbcertpem"
EOF

After installing db-cert bundle, ensure that you have db-cert configMap present in netbackup namespace with size 1 as follows:

bash-5.1$ kubectl get configmap db-cert -n $ENVIRONMENT_NAMESPACE
NAME      DATA   AGE
db-cert   1      11h

Note:

If the configMap is showing the size as 0, then delete it and ensure that the trust-manager recreates it before proceeding further.
