After creating self-signed wildcard certificates for modern browsers a while back, self-signed certificates came back to haunt me once again. This post describes a solution for creating self-signed keystores (pkcs12 or jks) in OpenShift and Kubernetes to use in Spring Boot applications to re-encrypt traffic.
