Hi, I have been working on a side project/tool in the elixir for loading which loads CSV files to the database.

It is an umbrella project, with 2 apps: an elixir application which holds the main logic, and a phoenix live view application that provides an interface to the user to use the tool. The user has to run the phoenix server locally and use the browser as an interface to the app. It just like other tools like phpMyAdmin that use the browser to provide an interface.

Now, I want to distribute this application to users, and my requirement is that there should be minimal dependencies and the user experience should be good.

There are some ideas to do this but I haven’t found a solution yet.

I have thought of 3 options to do this…

• 1st idea, using an Escript: I have earlier used escripts to distribute this app, and it worked fine, escripts only require the user to have erlang installed and have no OS dependency like releases. Also, escripts is a single binary file which makes it convenient to distribute and use.

Problems: Since now the project is an umbrella project and with the addition of the phoenix live view app, now I am not sure if escript will work. Not sure if things like assets and node modules in the phoenix app can be packed inside an escript. Can anyone guide me on this?

• 2nd idea, using releases: This seems like a good idea to me, there are no dependencies that the user needs here.

Problems:

As the docs say…

Once a release is assembled, it can be packaged and deployed to a target, as long as the target runs on the same operating system (OS) distribution and version as the machine running the mix release command.

So should I make a different release for each different OS distributions?
I work on ubuntu 18.04, in order to make releases for other OS distributions can I run the OS distribution in docker and execute mix release from inside the docker container running the required OS distribution, will this work? Any ideas anyone?

• 3rd idea, using Docker: I can package my app as a docker image using a docker file, we can get rid of all the dependencies on OS, etc. This seems good idea but…

Problems:

The users now will have to install docker first and run my app’s docker container to use it.

Also, my elixir application needs to access files from the user’s system, using docker means we will have to use docker volumes or bind mounts to access CSV files on the host machine, all this adds complexity and hampers user experience, which I would like to avoid.

These are the approaches I can think of there might be a better way to do this, that is not listed above, please share any ideas or suggestions you have.

Thank you!
