Running heatmapper locally with docker

[agostini01]

A friend of mine asked if I could enable running heatmapper web server locally.

I put together a Dockerfile and instructions that can be used to make this possible.

Not sure if you have interest in merging it, but this information may be useful for someone else, thus I am creating this issue.

Dockerfile:
https://github.com/agostini01/heatmapper/blob/master/Dockerfile

Instructions:
https://github.com/agostini01/heatmapper/blob/master/docker-instructions.md

Known issues:

• xlsx support is currently disabled
• In Expression "Upload File" does not work, but you can upload a single file using the "Upload Multiple Files" option
• The web server will run as root, be careful
• In Image Overlay, "Upload Grid" does not work. No workaround found.

Just tried on Ubuntu 20.04. The installation goes smoothly. Unfortunately in "Image Overlay" it is not possible to import any type of txt or csv file.

@alesresearch
yeah.. Just tried and only the image appears to upload.
This is a similar error to the "upload a single file" on "Expression".
So it may have to do with this Upload mechanism in general.
Funny enough, the Upload Image seem to work...

I dont know much about R and know nothing on serving R websites. I can help if you notice that a library is missing and I can adjust the docker script to install it, but I will let someone else tackle this upload isse.

Best,
Nico

@agostini01 ,
I will try to inspect the container and keep an eye on the logs for any errors. If I have any news, I'll bring it back here.

Best,
Paolo
