apiVersion: networking.k8s.io/v1
kind: IngressClass
metadata:
  annotations:
    ingressclass.kubernetes.io/is-default-class: "true"
  name: kong
spec:
  controller: konghq.com/ingress-controller

The important part is “ingressclass.kubernetes.io/is-default-class: “true””

that’s.

To run Longhorn storage only on the specific nodes:

• Download yaml manifest and update Longhorn config map “create-default-disk-labeled-nodes=true”
• Apply yaml
• Add label node.longhorn.io/create-default-disk=true to your dedicated storage nodes. Do nothing on another node.
• Done

For better result, you may apply taint to Longhorn nodes

That’s all

Sometime getting fact take long time to process

try this:

[defaults]gather_subset = min,network,!hardware

Next, looks wired ,but this can help me

ansible_ssh_common_args="-o ServerAliveInterval=15 -F /dev/null -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null"

Hope this help.

Velero is a great tool to do full backup/restore your k8s cluster ,but sometime you need to clean install it this is how.

#!/bin/bashvelero uninstall
kubectl delete ns velero
kubectl delete ResticRepository -n velero  $(kubectl get ResticRepository -n velero -o jsonpath='{.items[*].metadata.name}')velero install \
 -n velero \
 --provider aws \
 --plugins velero/velero-plugin-for-aws:v1.2.1 \
 --bucket velero \
 --secret-file ./credentials-velero \
 --default-volumes-to-restic=true \
 --use-volume-snapshots=true \
 --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=https://velero.myvelero.io \
 --use-restic --wait -n velero ; kubectl logs -f deployment/velero -n velero

verify

kubectl get BackupStorageLocation default -n velero  -o yaml

done

VirtualBox is my best friend for my Ansible testing and I need to re-create VMs all the time this is how

cd C:\Program Files\Oracle\VirtualBoxVBoxManage clonevm s201 --name="s201c1"  --snapshot s1 --options=keepallmacs,Link  --registerVBoxManage clonevm s202 --name="s202c1"  --snapshot s1 --options=keepallmacs,Link  --registerVBoxManage clonevm s203 --name="s203c1"  --snapshot s1 --options=keepallmacs,Link  --registerVBoxManage clonevm w204 --name="w204c1"  --snapshot s1 --options=keepallmacs,Link  --registerVBoxManage startvm s201c1 --type headlessVBoxManage startvm s202c1 --type headlessVBoxManage startvm s203c1 --type headlessVBoxManage startvm w204c1 --type headless

that’s all
