Allow run_shell_setup during Docker build

[jabez007]

In reference to this issue
#311

The idea is to use an ARG in the Dockerfile as a flag to indicate that we are in a build so that the install.sh will still execute run_shell_setup, and since we are in a Docker build pass the option to run_shell_setup so that the prompts are just answered with their defaults.

an example Dockerfile then would look something like

FROM debian:stable-slim

# Define a build argument to indicate the Docker build context
ARG DOCKER_BUILD=true

RUN apt-get update && \
  apt-get install -y \
  bash \
  curl \
  unzip

ENV SHELL="/bin/bash"

#RUN curl -fsSL https://deno.land/install.sh | sh
RUN curl -fsSL https://raw.githubusercontent.com/jabez007/deno_install/refs/heads/fix-docker/install.sh | sh

CMD ["/bin/bash"]

Hello, thanks for the PR!

I think instead of using an ARG and special casing docker builds, we should check if the user passed in -y or --yes, and if so run the shell setup regardless of whether it's an interactive terminal.

The steps for that would be roughly:

1. Update the arg parsing here to check for -y/--yes, and if it's present set some var (should_run_shell_setup or something)
2. Update the condition to be if { [ -z "$CI" ] && [ -t 1 ]; } || $should_run_shell_setup;

That way you could install deno in a dockerfile by just passing -y, so it would be consistent across environments instead of being dockerfile specific

So then the example Dockerfile would be something like

FROM debian:stable-slim

RUN apt-get update && \
  apt-get install -y \
  bash \
  curl \
  unzip

ENV SHELL="/bin/bash"

#RUN curl -fsSL https://deno.land/install.sh | sh -s -- -y
RUN curl -fsSL https://raw.githubusercontent.com/jabez007/deno_install/refs/heads/fix-docker/install.sh | sh -s -- -y

CMD ["/bin/bash"]

LGTM, thanks!
