Dockerkokoisilla

Dockerkokoisilla is a Finnish term used to describe software units that are intended for deployment in Docker containers with standardized size and resource characteristics to improve portability and reproducibility across environments. The name blends Docker with kokoisilla (the adessive plural form of koko, meaning “size”), reflecting the idea of items sized for Docker deployments. It is an informal concept used in Finnish IT communities, rather than an official standard.

Key features of dockerkokoisilla include lean base images, explicit and pinned dependencies, deterministic builds, and predefined resource limits (CPU and memory). Practitioners often employ multi-stage Dockerfiles, clear versioning, and explicit configuration through environment variables, with an emphasis on reproducibility from local development to production. Images are designed to be portable across Linux hosts, cloud runtimes, and container orchestrators such as Docker Compose and Kubernetes.

In practice, the concept supports faster deployments, easier testing, and safer security posture due to a smaller attack surface and fewer surprises when moving between environments. It also encourages packaging patterns that separate concerns and simplify updates, such as stateless services and externalized configuration.

The term remains informal and variably used across teams; some critics argue that focusing on “size” can overshadow other important factors like maintainability, observability, or correctness. Nevertheless, dockerkokoisilla has helped codify a set of best practices for container-ready software in Finnish-speaking contexts.
