The single biggest area of difference between the likes of Docker and the RouterOS `container.npk` feature is how you create containers from OCI images.

RouterOS combines Docker’s `create` and `load` commands as `/container/add`, the distinction expressed by whether you give it the `remote-image` or `file` option, respectively.

<a id="run"></a>There is no shorthand command like `docker run` for creating and starting a container in a single step. Moreover, the lack of Linux-like interactive terminal handling means a simple command like…

    $ docker run --rm -it alpine:latest
    sh-5.1# <do something inside the container>
    sh-5.1# exit

…is most briefly expressed under RouterOS as…

    > /container
    > add remote-image=alpine:latest veth=veth1 entrypoint=sleep cmd=3600
    … wait for it to download and extract …
    … poll with "print" commands to get the container ID …
