Kubernetes Tips & Tricks

Easier handling of multiple configurations

1. Place configs under ~/.kube/contexts, i.e.

$ tree ~/.kube/contexts
/Users/jon/.kube/contexts
├── config-dev

public class Java14RecordExample {
    public static void main(String[] args) {
        var p = new Person("Boz", "Scaggs");

        System.out.println("toString(): " + p);
        System.out.println("---");
        System.out.println("Howdy " + p.name() + "!");
    }
}
