I think I don't understand very well the question. Docker is a platform to use containers. Bitnami provides applications and infrastructure Stacks for almost every platform.
Bitnami helps you to use any app on the platform you desire offering Native Installers, Virtual Machines, Cloud Images, Docker Images and Helm Charts in order to deploy containers on Kubernetes.
You can use Docker and Bitnami if you desire to do it. For example, if you are developing an application, we offer the Development containers to start using Docker Containers with everything you need to deploy an app. More info at:
