Heya – I’ve got Docker running on Ubuntu, Mac and Windows (WSL2). I’m getting really consistent issues arising from file system differences – most often, by running images (such as dpage/pgadmin) that do chmod commands – that fail because of the Windows file system. Obviously, the same images work fine […]

Hi all, I would like to get some more ideas of what people are using for real production scale deployments? More often than not I find myself testing tools like terraform, helm and being awed first until I realize again that I can do more complex deployments faster and in […]

I’ve been working with k8s for about a year now, but only recently started exploring some of the abstraction tools — I’ve been doing most things through manual kubectl apply up until now. I’ve also spun up clusters completely from scratch (following k8s the hard way), using Terraform, and using […]
