Hi, some container images and docker applications require -p command to set the port of application/container and map it to the host (ros). i know that i can use DST NAT to expose(map) a container to outside, but how could i define the application port number running inside the container.
consider this for example: if we don't define the port, the application inside the container may not start listening on any port or it will use a random one(maybe).
thanks for the help

-p flag in docker maps ports in similar way as dst-nat does in MikroTik. Container should not care about -p parameter, as it's done on network layer above it.

To add to @antonsb's answer, dstnat rules allow you to map one port number to another, same as Docker's `-p` flag.

Indeed, Docker's default network is a NAT system, and its `-p` flag does this same type of dstnat mapping. RouterOS's container runtime has many differences from Docker's, but in this case, it's an exact 1:1 mapping. You don't need MikroTik to add anything new here.
