Rash Book

    rash solves an optimization problem in the containers ecosystem.

    Nowadays, you generally need to write container entrypoints in bash or include them in the binary, i.e. the program itself. This is a trade-off decision between being fast or being reusable, efficient, flexible…

    Besides, entrypoints share use cases between different kinds of applications, e.g. databases entrypoints are quite similar. Likewise, you might need to provision your containers between different platforms with the same tools, paying attention to secrets, configuration management…

    rash provides:

    • A simple syntax to maintain low complexity.
    • One static binary to be container oriented.
    • A declarative syntax to be idempotent.
    • Clear output to log properly.
    • Security by design.
    • Speed and efficiency (TODO: performance tests versus bash).
    • Modular design.
    • Support of Tera templates.
