Secrets are very similar to Kubernetes ConfigMaps and Docker Swarm configs. Everything we said for configurations applies to Secrets, with a few additional features.
Both Kubernetes and Docker Swarm stores Secrets in tmpfs inside containers. From that aspect, they are equally secure. The significant difference is in the way Secrets are stored internally.
