How to specify in Dockerfile that the image is interactive?

Question

I have created a docker container that runs a command line tool. The container is supposed to be interactive. Am I somehow able to specify in the Dockerfile that the container is always started in interactive mode?

For reference this is the dockerfile:

FROM ubuntu:latest

RUN apt-get update && apt-get -y install curl

RUN mkdir adr-tools && \
    cd adr-tools && \
    curl -L https://github.com/npryce/adr-tools/archive/2.2.0.tar.gz --output adr-tools.tar.gz && \
    tar -xvzf adr-tools.tar.gz && \
    cp */src/* /usr/bin && \
    rm -rf adr-tools

CMD ["/bin/bash"]

EDIT: I know of the -it options for the run command. I'm explicitly asking for a way to do this in the docker file.

EDIT2: This is not a duplicate of Interactive command in Dockerfile since my question addresses an issue with how arguments specified to docker run can be avoided in favor of specifying them in the Dockerfile whereas the supposed duplicate addresses an issue of interactive input during the build of the image by docker itself.

Answer 1

Many of the docker run options can only be specified at the command line or via higher-level wrappers (shell scripts, Docker Compose, Kubernetes, &c.). Along with port mappings and network settings, the “interactive” and “tty” options can only be set at run time, and you can’t force these in the Dockerfile.

Answer 2

You can use the docker run command.

docker build -t curly .
docker run -it curly curl https://stackoverflow.com

The convention is:

docker run -it IMAGE_NAME [COMMAND] [ARG...]

Where [COMMAND] is curl and [ARG...] are the curl arguments, which is https://stackoverflow.com in my example.

-i enables interactive process mode. You can't specify this in the Dockerfile.
-t allocates a pseudo-TTY for the container.
