Our team loves the simplicity of using Docker Compose for local feature development and running automated integration tests in our CI/CD pipelines. However, our production environment runs on managed Kubernetes. Is it standard practice in modern software engineering to use both tools simultaneously, or should we migrate our local environments to something like Minikube?

Yes, using Compose locally and Kubernetes in production is very common. It keeps local machines running fast while keeping production resilient, giving you the best of both worlds.
It is extremely common and considered a best practice in many DevOps teams to combine both tools. Developers prefer Docker Compose because it boots up in seconds, uses minimal system resources, and allows rapid code iteration without compiling complex cluster manifests. Production infrastructure requires the high availability, auto-scaling, and monitoring capabilities of Kubernetes. Maintaining both means keeping your Compose files updated for local work and your Helm charts or manifests updated for production deployments.
Doesn't maintaining separate configuration files for both Docker Compose and Kubernetes create a massive configuration drift risk where local environments behave differently than production?
Gregory, it absolutely does create that risk. To mitigate this, teams use automated linting tools or switch local development to micro-clusters like Minikube or Kind so that the exact same manifests are tested locally before hitting production.
Fully agree with Douglas. Forcing developers to run a full local Kubernetes cluster just to change a line of frontend code ruins productivity. Compose is perfect for daily development tasks.
