Was just talking about this the other day - although more in-line with a custom controller to replace _all_ secrets / env variables used at runtime automatically (LD_PRELOAD get_env ?). Recognize this serves a different use case - I was trying to only decrypt KMS encrypted secrets in-memory / in-flight so that an attacker would have a harder time reading secrets in-cluster or in pod shell.
Such a sick idea, and incredibly useful. Would be nice if it integrated directly with secrets managers RE: ESO
