add Dockerfile and docker-compose

[stefanocudini]

I'm created a new PR based to node docker image

many of the points from the previous discussion have been solved

#327

[stefanocudini]

docker-compose.yml is optional, it's only an example for usage image under production environment..

I'm not with the project anymore actually. However, a quick glance at the dockerfile suggests that you actually only addressed the image thing. The other points are still a problem. Copied from the original discussion:

• too many RUN statements (each RUN adds another layer to the final image, only useful if you're having multiple images share a certain set of base commands, not useful here..)
• no LABEL like maintainer
  - Ubuntu base image is not ideal, e.g. node:12.13.1-alpine or similar is better
• also there's no need to git clone the repository: you're already inside it with Docker (this is pretty important)

Also:

• either remove the commented out statements or explain why they could/should be uncommented
• let's not mix YAML and JSON notation, i.e. lists in docker-compose, rather like this:

ports: 
- 8080:8080

Hi @stefanocudini ,

sorry for the long wait.

I've finally taken some time to do this.

Please take a look at this branch

It would be great if you could test it out and tell me if it works with a local ors backend (i don't have one installed and it would take me quite some time to do that i suppose..)

The app deployment should now be pretty straight forward using docker-compose.

I think also developing should work due to the watches and volumes passed in docker-compose.

Hopefully also this will also help our backend guys to quickly pair a client with their development environment :)

Hope to hear from you

A little info to the change:

• using other image with git + node preinstalled
• avoid cloning the repo, instead copying needed files & paths to the docker container
• using app folder as volume (not sure if the single file volume for Gruntfile.default works. Docker sometimes acts strange with single files)
• Add changelog & readme
• move command to docker-compose so building and running is separated
• based on current development branch including ng-slider cleanup change which makes installing and running less "breaking"
