251447-screenshot1552.jpgHi All,

I have a AKS running with 5 nodes, however not all nodes is running the workload.

I have created a quick start application and selected the image from integrated ACR. The first node created are ready to accept load as end point, but not other nodes in the same Node Pools.

Wonder what settings or configuration is missing in my AKS?

Best regards,
Soon Joo

    Hello @SoonJoo@Genting ,
    If you want your application pods to run and distribute on each node , then you have to deploy your application using DaemonSet YAML file.
    More details about DaemonSet : https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

    By default, when you deploy the application using "Deployment" YAML Spec object with number of replicas - those application pods can go and sit randomly on any of the available nodes;
    You can also use the concept of "Taints & Tolerations" https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/

    Regards,
    Shiva.

    Just realised not all pods are running on the nodes, what should I do to make sure all the pods with the apps should be running on each of the nodes?

    Thanks!
