Best way to maintain Dependent softwares with versions in docker images?

I am new to dockers, well we started working on docker file but I am stuck on how to maintain different versions of dependent software's of our web app.

suppose our web app uses crystal reports 1.X version, in runtime.

In future , if want to update version of crystal report to 1.2.X.

In these scenarios how a docker file and these dependent software's should be maintained(although version we can directly update in docker file)?

Should docker file be parametrised for the versions?

What would be the best approach?

Use your application language's native package dependency system (a Ruby Gemfile, Python Pipfile or requirements.txt, Node package.json, Scala build.sbt, ...). In a non-Docker development environment, maintain these dependencies the same way you would without Docker. When you go to translate this into a Dockerfile, copy these description files into the image and install them.

A near-universal Javascript Dockerfile, for example, would look like

FROM node:12
WORKDIR /app

# Copy in and install dependencies
COPY package.json yarn.lock .
RUN yarn install

# Copy in the rest of the application; build and set up to run it
COPY . .
RUN yarn build
EXPOSE 3000
CMD yarn start

If a dependency changed, you'd use a command like yarn up to update the package.json and yarn.lock files in your non-Docker development environment, and when you went to re-docker build, those updated files would update the dependency in the built image.
