I have used Docker as a pivotal development tool for over a decade, including its satellite technologies (docker-compose, Kubernetes, etc). For countless projects, Docker played a role in least an initial phase, enabling me to quickly stand up technologies and link them; it also served as a perfect mechanism for repeatable deployments with carefully frozen system dependencies and settings.

As for container orchestration, I have used Kubernetes both in production deployment (on GKE) and for local development or internal servers, relying on all major components of its infrastructure (ingresses, provisioned storage, etc) to coordinate microservice-driven projects that often consist of various APIs, databases, and task-running queues.
