Do you have more practical experience with containerization via Docker or with orchestration using Kubernetes?

I have more practical experience with containerization through Docker. I regularly create Dockerfiles for applications, configure images, and manage containers locally and in CI/CD.

I have some experience with Kubernetes, but it is limited to basic deployment and cluster setup, writing manifests for deployments and services. My main focus has been on creating and optimizing containers, with orchestration at a beginner level.
