Explanation
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
