soju is a compelling modern alternative to the classic znc and psybnc IRC Bouncers.

See also:

The dockerizer version - https://git.sr.ht/~fourstepper/docker-soju

It's also trivial to build from source via docker:

    git clone https://git.sr.ht/~fourstepper/docker-soju
    cd docker-soju
    docker build -t docker-soju:$(date +%Y%m%d) .

Then you will need to create ./soju-data/soju.cfg as per the docs https://soju.im/doc/soju.1.html.

Pretty snazzy, have fun.
