Hey @nyrahul and @webdevgopi, thanks for the PR.

[gopiak]

Hi folks,
I apologize for making the commit history more cluttered.
The latest commit should address all the issues.

[nyrahul]

@webdevgopi, can you please check why lint and run tests are failing?

[ktsakalozos]

@webdevgopi @nyrahul, I have fixed the lint errors. Please make sure you fetch the last commit.

Thank you for addressing the comments @webdevgopi. The microk8s enable command is now failing with:

ubuntu@u1:~$ sudo microk8s enable kubearmor

I am sorry, the addon is still failing.

[gopiak]

Hi everyone,
The tests are failing in strict mode. I have added a skip condition in strict mode testing.

Thank you for this work @webdevgopi @nyrahul. The addon will be available with the 1.28 release (mid August) and until then you can find it in the releases on latest/edge channel.

Every addon gets its own page in our documentation linked from [1]. I have prepared a basic landing page for you. Please have a look at it and let me know if you need to change it in any way.

Many thanks!
