I have asked myself this question and invested time researching it. Running out of time. Can someone point me in the right direction? I have created a kubernetes cluster on minikube, with its Ingress, Services and Deployments. There is a whole configuration of services in there. Can, now, I point this kubectl command to another provider like VMWareFusion, AWS , Azure, not to forget Google Cloud. I know about kops. My understanding is that although this is the design goal of kops but presently it only supports AWS.
Yes, you can use different clusters via the context. List them using kubectl config get-contexts and switch between them using kubectl config use-context.
I would like to suggest you couple of things the way i worked out with kubernetes, From my local system to production my environment remains consistent.
I use kubeadm to create a kubernetes cluster on my local machine. And I maintain all my kubernetes resources like Services, Pods, Deployment etc.. in a yaml as my deployment files.
All my services and pods are saved in a yaml file e.g. counter.yaml
kind: Deployment apiVersion: extensions/v1beta1 metadata: name: deployment-counter namespace: default labels: module: log-counter spec: replicas: 1 selector: matchLabels: module: log-counter template: metadata: labels: module: log-counter spec: containers: - name: container-counter image: busybox command: - "/bin/sh" - "-c" - 'i=0; while true; do echo "$i: $(date)"; i=$((i+1)); sleep 1; done' imagePullPolicy: Always restartPolicy: Always terminationGracePeriodSeconds: 30 tolerations: - key: ud_application operator: Equal value: docxtract effect: NoSchedule - key: ud_module operator: Exists effect: NoSchedule strategy: type: RollingUpdate
On my local kubernetes cluster provisioned by kubeadm I deploy it as follow
kubectl apply -f counter.yamlAnd on Production i have a kubernetes cluster provisioned by kubeadm too and i deploy it the same way.
kubectl apply -f counter.yaml
kubeadm is a tool provided by kubernetes to provision a kubernetes cluster.
