About Docker
Docker turned containers from kernel arcana into the default unit of software delivery. Build an image, run it identically on any laptop or cloud, share it through Docker Hub. Desktop tooling, Compose for multi-service apps, and build acceleration keep it central to daily development even as orchestration moved to Kubernetes. Business licensing changes annoyed some, but the workflow endures.
