kubectl:tldr:f7373
The command "kubectl explain" is used to provide details and explanations about the different fields and options available in Kubernetes resources. The "${pods-spec-containers}" is a placeholder for the specific resource you want to get explanations for.
In this particular command, you would replace "${pods-spec-containers}" with the resource you want to explore. For example, if you want to understand the available options for the "containers" field in a Pod specification, you would use:
kubectl explain pods.spec.containers
By executing this command, Kubernetes will provide you with detailed explanations of each field, option, and their possible values within the "containers" field of a Pod specification. This information can be extremely useful while composing or modifying Kubernetes resource configurations.
