BOSH & SSL Certificates - Rotating Certificates Smoothly
summary
Describes a three-step certificate rotation that uses CredHub and the Kube App transitional-flag workflow: create a new CA with transitional set and deploy so every VM gets both CAs, flip the transitional flag to the old CA and run mass-regenerate to reissue all end-entity certs, then remove transitional from the old CA and deploy. Claims eliminate no ops-files maintenance and manual ops-file juggling; warns a BOSH Director bug needs a patch (it can drop one cert and hides diffs).
