Pods are created in a sequential order when a StatefulSet is set up. This means that for a StatefulSet with N replicas, the Pods are deployed one by one, starting from the Pod with the index 0 and ending with the Pod with the index N-1. Each Pod has to be in the Running and Ready state before the next Pod is created. This ensures that the Pods have a predictable and unique identity and can be connected to their corresponding persistent volumes. References: 

 The kubectl command to list pods with the exact label “env-dev” is kubectl get pods -l env=dev. The -l or --selector flag allows you to filter pods by label selectors, which are key-value pairs that are attached to pods. The = operator matches pods that have the exact label value specified. The -L or --label-columns flag adds a column with the value of the specified label(s) to the output, but does not filter the pods. The -I or --ignore-not-found flag returns an exit code of 0 when no resources are found, but does not affect the output. The -l env-dev flag is invalid, as it does not specify a label value. References: 6, 7, 9

kubectl is a command-line tool that allows you to run commands against Kubernetes clusters1. You can use kubectl in SAP BTP, Kyma runtime for the following purposes:

• To run interactive commands. kubectl supports various commands that let you interact with your cluster resources, such as creating, updating, deleting, describing, or executing them. For example, you can use kubectl create to create a resource from a file or kubectl exec to run a command in a container2.
• To view pod logs. kubectl allows you to view the logs of a pod or a container in a pod using the kubectl logs command. This can help you troubleshoot issues or monitor the pod activity3.
• To forward ports from remote machines to pods. kubectl enables you to forward one or more local ports to a pod using the kubectl port-forward command. This can allow you to access a pod from your local machine for debugging or testing purposes4.
