The essential downside to using containers is that you are adding layers of abstraction to your infrastructure. Adding layers of abstraction usually increases complexity. However, layers of abstraction should also bring benefits wherever they're used. Docker and Kubernetes go hand-in-hand with distributed software or "microservices." If you don't see any benefit to that architecture, you're likely going to introduce unnecessary complexity into your infrastructure with containers. The more deployments of individual software applications you make, the more you can gain from containers. And the inverse is also true - if you rarely deploy new versions or updates to your software, using containers will require tackling complexity that doesn't benefit your use-case.
