Scaling IBM Control Desk Workloads Pods
Scaling is one of the important features provided by Kubernetes. It allows to dynamically increase/decrease the deployment instances when the load or traffic increases.
Scaling of ICD-UI pod can be achieved in containerized ICD environment by
executing the below command on master node of
cluster:
kubectl scale -n icd deployment icd-ui --replicas=2Here icd is the namespace where our workload deployment icd-ui
is deployed. Replicas shows the number of pods desired.
On scaling up, the number of deployment instances increases to 2 which means two pods are created
for icd-ui deployment. When a user login to IBM
Control Desk application, the request can go to
any of the two deployments. Both the deployments will connect to icd-ui service and
can be accessed by the service which acts as a load balancer.
Similarly, scaling can be achieved on other workload deployments.
To scale down to reduce number of replicas, execute below
command:
kubectl scale -n icd deployment icd-ui --replicas=1
