SAP was the first to adopt this pattern with it's SAP Gardener.
There's currently an open source project working towards making this pattern possible for vanilla K8s named "Kamaji".
Redhat started lately this approach with hypershift.
Looks promicing, wish u lot of success with the product.
I have also the same issue now with my Samsung Galaxy note 10 plus. This device has insane specs (12 GB of RAM, really good camera and display, the battery still last over 1,5 days, and could still be usable in the next 3 years. I would though need to replace it next year, only because of the lack of security patches.
This is really crazy, when i think that i am still getting updates on a 7 years old laptop (both windows and linux).
I am very happy using shorewall. Thanks a lot Mr.Eastep for your time spending on this awesome software. we need to migrate the project to github or gitlab and maybe submitting the project in codeshelter.co to find collaborators.
