我们如何使用kubernetes api进行kubernetes集群信息转储

Question

Does kubernetes provide an API in its client library to get the cluster-info dump. I went through its API documentation and could find any api which could actually do this.

What i do now: kubectl cluster-info dump --output-directory="dumpdir"

What i want: Using client-go/kubernetes api libraries, make an API call to get this dump from a golang application. Is it possible?

What i know: There are individual API's for each resource which can provide all the information provided by the cluster-info dump, but i want to do it will a single API call.

For example: golang code:

coreClient := kubernetesapi.CoreV1()
nodeList, err := coreClient.Nodes().List(metav1.ListOptions{})

This will give me a list of nodes.

Is there an API which returns what "kubectl cluster-info dump" would give. So i can get all the details Programmatically.

Backup and restore cluster resources:

Use ark for cluster backup and resotre:

ark schedule create <SCHEDULE NAME> --schedule "0 7 * * *"

ark restore create --from-backup <BACKUP-NAME>
