    Docker: when it makes sense.

    Docker is indispensable for any modern team seeking reproducibility and cloud deployment; less essential for scripts or monolithic tools.

    Keep if

    You're developing in a team and need reproducibility.. You deploy on Kubernetes or cloud orchestration.

    Challenge if

    You're working with statically compiled binaries only.. You're on heavily resource-constrained machines.
