[#2145] Dockerisation of RepoSense

[georgetayqy]

Part of #2145

Proposed commit message

Currently, there are some issues with regard to consistent testing of
code, especially for the frontend code, due to the difference in
environments where the test cases are run (developer's machine VS
Github Action's workers). This inconsistency in testing results makes
it hard for us to really distinguish false negatives/false positives.

Moreover, this inconsistency in the environment where RepoSense is
installed may also result in dependency issues.

In this PR, a proof-of-concept Dockerfile and docker-compose.yml file
will be provided first to test the viability of such an integration
into RepoSense. Future implementations would see further integration of
Docker into Github Actions, more complicated Docker build processes and
tests and documentation on how to maintain these Docker files and
builds.

Let's move to integrate Docker and Docker Compose into RepoSense to
mitigate and potentially solve some of the aforementioned issues, by
providing users and developers a more standardised environment where
they can run or test RepoSense.

Other information

This PR is part of the following steps outlined in the parent issue:

• Create Ubuntu Dockerfiles
• Integrate Ubuntu Dockerfiles with Github Actions

For this PR, only Ubuntu/Linux images are explored, as the rest are in development. Ubuntu/Linux images are also easier to work with and far less fussy compared to Windows and MacOS images, hence starting work on Ubuntu/Linux might be a helpful proof of concept for the viability of Docker for use for testing.

Do note that the Docker containers currently do not conduct frontend tests using cypress, even though the dependencies are installed on the base Ubuntu containers, as they are consistently failing CI. Will look into the cause and update this thread once I have isolated the cause of the error.

LGTM! We just need to fix the Cypress issues.

This should probably be 22.04.

Suggested change

	LABEL "os.version"="20.04"
	LABEL "os.version"="22.04"

Is this going to be re-added?

[sopa301]

As discussed, since we're not using this for the CI, we can probably put this in a folder marked for local testing.

As mentioned in issue #2145, we are not pursuing this idea, hence I am closing out this PR.
