One or more containers do not have resource limits (Kubernetes) warning in vscode kubernetes tools

It is a good practice to declare resource requests and limits for both memory and cpu for each container. This helps to schedule the container to a node that has available resources for your Pod, and also so that your Pod does not use resources that other Pods needs - therefore the "this could starve other processes" message.

E.g. to add resource requests and limits to your example

apiVersion: v1
kind: Pod
metadata:
  name: myapp-pod
  labels: 
    app: myapp
    type: server
spec:
  containers:
  - name: nginx-container
    image: nginx
    resources:
      limits:
        memory: 512Mi
        cpu: "1"
      requests:
        memory: 256Mi
        cpu: "0.2"

As you know, that warning comes from the linter in VS Code Extension ms-kubernetes-tools.vscode-kubernetes-tools. If you want the linter to disable the warning

One or more containers do not have resource limits - this could starve other processes

then edit VS Code setting.json to look like this:

{
    "vs-kubernetes": {
        "disable-linters": ["resource-limits"],
        ...
    },
    ...
}
