Component

JKube Kit

Task description

Description

In EnvUtil, we have check size of the Map before returning it
https://github.com/eclipse/jkube/blob/c4ee9d4e9432297c50d9385a8c06d1fea0f75e3a/jkube-kit/common/src/main/java/org/eclipse/jkube/kit/common/util/EnvUtil.java#L265

There is an isEmpty() method available in Map interface. We should rather use it rather than doing explicit size check. It would improve readability.

Expected Behavior

ret.size() > 0 is replaced with !ret.isEmpty()

Acceptance Criteria

• ret.size() > 0is replaced with!ret.isEmpty()`
• Project compiles cleanly after making changes

How to manually test my changes

Kubernetes

If you don't have a real Kubernetes cluster available (most probably), you can use Minikube or Kind to test with a local cluster.

• Minikube get started guide
• Kind (Requires Docker) quick start

OpenShift

If you don't have a real OpenShift cluster available (most probably), you can use Red Hat's developer Sandbox for Red Hat OpenShift. The only requirement is to have a Red Hat account.

Once you have your Sandbox environment, you'll need to download the oc tool from the cluster console.
(Press the ? icon and from the context menu select Command line tools, you'll be redirected to https://$subdomain.openshiftapps.com/command-lines-tools where you'll be able to download the CLI for your platform)
