Answer» use --dry-run flag to test the manifest. This is really useful not only to ensure if the yaml syntax is right for a particular Kubernetes object but also to ensure that a spec has required key-value pairs. kubectl create -f <test.yaml&GT; --dry-run Let us now look at an example Pod spec that will launch an NGINX pod ○ → cat example_pod.yaml --- apiVersion: v1 kind: Pod metadata: name: my-nginx namespace: mynamespace spec: CONTAINERS: - name: my-nginx IMAGE: nginx ○ → kubectl create -f example_pod.yaml --dry-run pod/my-nginx created (dry run)

kubectl create -f <test.yaml&GT; --dry-run

Let us now look at an example Pod spec that will launch an NGINX pod

○ → cat example_pod.yaml --- apiVersion: v1 kind: Pod metadata: name: my-nginx namespace: mynamespace spec: CONTAINERS: - name: my-nginx IMAGE: nginx ○ → kubectl create -f example_pod.yaml --dry-run pod/my-nginx created (dry run)
