this is the new dockfile
FROM ubuntu:latest
RUN apt-get update
RUN apt-get install -y curl && \
curl -sL https://deb.nodesource.com/setup_16.x | bash -
RUN apt-get install -y nodejs
RUN apt-get install -y wget
RUN apt-get install -y gnupg
RUN wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb && dpkg -i erlang-solutions_2.0_all.deb
RUN apt-get install erlang
RUN apt-get install elixir
WORKDIR /home/jill/main/Pod/elixir_app
COPY . .
RUN mix compile
CMD [“mix”, “run”]
Worked for me… maybe you’re forgetting -y, i.e…
RUN apt-get install -y erlang
Also, why build/install yourself? There are ready to use Docker images with most ErlangOTP/Elixir/OS combos.
For example, hexpm/elixir:1.14.3-erlang-25.3-ubuntu-jammy-20230126
https://hub.docker.com/r/hexpm/elixir/tags?page=1&name=1.14.3-erlang-25.3-ubuntu
An aside, I can’t believe how bad Docker Hub’s search tag feature is. It’s terrible.
