Hi,

It is possible to manually renew the certificates by generating a new public-cert/private-key pair via openssl, then apply it as a secret in K8s and finally label it with the sealedsecrets.bitnami.com/sealed-secrets-key=active label so that it gets picked up by the controller upon re-deployment.

After that, the "v1/cert.pem" endpoint exposed by the controller will point to the most recent certificate and kubeseal can consume it to seal new secrets

  1. Generate a new certificate
  SECRET_NAME="sealed-secrets-pub-key-$(date +'%s')"
  SEAL_PUB="${SECRET_NAME}-cert.pem"
  SEAL_PRIV="${SECRET_NAME}-priv.key"

  openssl req -x509 -nodes                               \
                    -days 3650                           \
                    -newkey rsa:4096                     \
                    -keyout "$SEAL_PRIV"                 \
                    -out "$SEAL_PUB"                     \
                    -subj "/CN=Sealed Secrets Controller/O=Team"
  1. Create a TLS secret in k8s with the content of the certificate
kubectl create secret tls $SECRET_NAME --cert=$SEAL_PUB --key=$SEAL_PRIV
  1. Label it appropriately
kubectl label secret $SECRET_NAME "sealedsecrets.bitnami.com/sealed-secrets-key=active" --overwrite

Finally, you can confirm that the new secret was picked up by the controller after re-deploying it

 $ k logs sealed-secrets-ctr-any-infra-example-nhn2h | head -n30
controller version: 0.22.0
