All apt operations should be put in a single RUN, see: https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#run

Something like:

RUN apt-get update -q && apt-get install -y --no-install-recommends \
    yarn \
    git \
    …
    …
    …
 && rm -rf /var/lib/apt/lists/*

At the end the apt cache is no longer required and deleted, for a slimmer container image.

Same with the rest of the similar RUN instructions.

RUN opam init
RUN opam install dune

RUN yarn global add [email protected]
