Here is the Dockerfile

erlang# ===== Stage 1: BUILD OTP 27.2 =====
FROM debian:bookworm AS build

RUN apt-get update && apt-get install -y \
    build-essential \
    autoconf \
    automake \
    libssl-dev \
    libncurses5-dev \
    libncursesw5-dev \

    tar

WORKDIR /src

RUN wget https://github.com/erlang/otp/archive/refs/tags/OTP-27.2.tar.gz -O otp.tar.gz && \
    tar xzf otp.tar.gz

WORKDIR /src/otp-OTP-27.2

RUN ./configure --prefix=/opt/erlang --with-ssl --enable-tls
RUN make -j$(nproc)
RUN make install

# ===== Stage 2: Runtime =====
FROM debian:bookworm

RUN apt-get update && apt-get install -y openssl && rm -rf /var/lib/apt/lists/*

COPY --from=build /opt/erlang /opt/erlang
ENV PATH="/opt/erlang/bin:${PATH}"

WORKDIR /app

RUN mkdir -p /etc/pki/tls/certs /etc/pki/tls/private

RUN openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
    -keyout /etc/pki/tls/private/localhost.key \
    -out /etc/pki/tls/certs/localhost.crt \
    -subj "/CN=localhost"

COPY ssl_dist.conf .
COPY epmd_static_map.erl .
RUN erlc epmd_static_map.erl

Here are the commands I ran
sudo docker build -t erlang-epmdless .

docker network create mynet
docker run -d --name node1 --hostname node1 --network mynet erlang-epmdless erl -name node1@node1 -proto_dist inet_tls -ssl_dist_optfile /app/ssl_dist.conf -epmd_module epmd_static_map -start_epmd false -noshell

when running above getting following
Protocol ‘inet_tls’: not supported
Tried following also by changing version still same
