Learning Tuesday: Create dev container

[mbussolotto]

What does this PR change?

• setup dev container
• create dev container during PR

Example: mbussolotto#4: clicking on Create Codespace it's possible to create a golang container environment where compile, run unit test and change the code. Container timeout and retention it's a user setting https://github.com/settings/codespaces.

All personal GitHub.com accounts include a monthly quota of free usage each month. GitHub will provide users in the Free plan 120 core hours, or 60 hours of run time on a 2 core codespace, plus 15 GB of storage each month.

@cbosdo , @rjmateus @juliogonzalez what do you think? I had this test with uyuni-tools, but my idea is to try to do something similar for uyuni: the goal would be have a quick online environment that can be used e.g. in cause of unit-test and/or linting test failures

Is it possible to preload the go dependencies? they take a while to download. But that seems cool for newcomers.
Also I would add a link to the codespaces pricing and getting started doc: closing the browser tab is not enough to stop the created codespace...

[mbussolotto]

Is it possible to preload the go dependencies?

yes, it's possible, and it can be done in different ways: I just need to understand which is the best way for our scenario. This would be also more important for uyuni repo.

closing the browser tab is not enough to stop the created codespace...

IIUC when you close the tab, the container will be idle and you can set Default idle timeout here https://github.com/settings/codespaces . But I need to do more test on it

[rjmateus]

it looks really cool :)

I am testing this... how can we stop the codespace? :-D

Not sure if I did it somehow, or I was just idle for enough time, but...

[juliogonzalez]

Idea looks cool! And I'd start implementing it here, and then I'd think of Uyuni as you told. And if for whatever reason we can't use it there, we can always use it here and at other repos.

See if you can preload go dependencies as Cedric requested.

But again, idea is great!

[juliogonzalez]

As Cedric mention, see please add info about the prices, as it's relevant.

When I launched it, it told me my user was going to pay for it, in such case it means the standard limit for most users will be 180 core hours/month as explained at https://docs.github.com/en/billing/managing-billing-for-github-codespaces/about-billing-for-github-codespaces (and 15GB storage). Thats 22,5 days per month at 8 hours per day). Assuming the machine used has only one core, otherwise it's less.

If the user is Pro, then then more resources are assigned.

[juliogonzalez]

Maybe also a link to the "getting started doc".

[juliogonzalez]

Do we really need a changelog for this :-?
