Container image build with Github Actions

[JelsonRodrigues]

Here I propose that a Github Actions is created to automatically build the container image once anything is merged on the main/master branch.

This idea is meant to simplify the process of people using new versions of the application.
As the application is already deployable as a container, I think it would be nice to have an official image release on this repo.

With Github Actions it's possible to create an automation that anytime a commit is made on the main branch, an event is triggered that can build the application and release the latest changes to an container image.
With this automatic release approach it can be easier for people to test and deploy the app on the Vyos router.

For example, once the container is already created on the router, to update and have the latest changes is simply a matter of running

add container image github_image_release_url_here latest
restart container container_name_here

The ease of use can help bring more people to the project and get more feedback and contributions.

Also, if we start using GitHub Actions, is possible to run a battery of tests on each merge request, and automatically see if the changes are breaking anything

Deffiently something that will come soon! I do not have much experince with github actions so have to take a look at that! :)

I can help with that. I've used in the past. Although there are somethings that only the repo owner can setup.

This guide might help with the barebones setup for this.

#64 was merged

Thanks to @JelsonRodrigues and @holow29

I will also add something into the documentation - definitely useful for Podman deployments inside VyOS.
