Setting up Kind Cluster, example abc
Kind Cluster usually prefix desired name with kind, so if you are creating a cluster with name abc the name will be kindabc
$ kind create cluster --name abc
$ kubectl config use-context kind-abc
kind get clusters
Finding the node name for a given and
kubectl get nodes -n default
Setting the Kind Cluster Context
kubectl cluster-info --context kind-abc
Kind recommends to always load docker image and Never use Always image pull policy
NOTE: The Kubernetes default pull policy is IfNotPresent unless the image tag is :latest or omitted (and implicitly :latest) in which case the default policy is Always. IfNotPresent causes the Kubelet to skip pulling an image if it already exists. If you want those images loaded into node to work as expected, please:
For Lab 1, you need the following docker image locally. once the images are available locally, load the same in kind cluster named 'abc'
kind load docker-image --name abc gcr.io/spark-operator/spark-operator:3.1.1
kind load docker-image --name abc docker.io/apache/airflow:2.2.4
kind load docker-image --name abc docker.io/apache/airflow-statsd-exporter-2021.04.28-v0.17.0
kind load docker-image --name abc docker.io/bitnami/postgresql:11.12.0-debian-10-r44
kind load docker-image --name abc gcr.io/spark-operator/spark-operator:3.1.1
kind load docker-image --name abc quay.io/minio/mc:RELEASE.2022-04-16T21-11-21Z
kind load docker-image --name abc quay.io/minio/minio:RELEASE.2022-04-26T01-20-24Z
kind load docker-image --name abc pysparkexample:aws
kind load docker-image --name abc k8s.gcr.io/git-sync/git-sync:v3.4.0
docker exec -it abc-control-plane crictl images ps
Launch lens and validate the cluster, which will show no Pods, but Nodes
- If the cluster is not launching, check the Docker Memory/Cores
- Port Forwarding from Lens doesnt work properly, use commandline to do the same
