Pod Connectivity

Create a namespace

Create a namespace so that the resources you create in this exercise are isolated from the rest of your cluster.

kubectl create namespace mem-example

Specify a memory request and a memory limit

To specify a memory request for a Container, include the resources:requests field in the Container's resource manifest. To specify a memory limit, include resources:limits.

In this exercise, you create a Pod that has one Container. The Container has a memory request of 100 MiB and a memory limit of 200 MiB. Here's the configuration file for the Pod:

Create the Pod:

kubectl apply -f https://k8s.io/examples/pods/resource/memory-request-limit.yaml --namespace=mem-example

Verify that the Pod Container is running:

kubectl get pod memory-demo --namespace=mem-example

View detailed information about the Pod:

kubectl get pod memory-demo --output=yaml --namespace=mem-example

Run kubectl top to fetch the metrics for the pod:

kubectl top pod memory-demo --namespace=mem-example

Delete your Pod:

kubectl delete pod memory-demo --namespace=mem-example
