KubExporter

KubExporter allows you to export resources from kubernetes as yaml/json files.

The configuration allows customization on which resources and which fields to exclude.

Usage

kubexporter --config config.yaml

Config

KubExporter exports by default all resources and allows to exclude unwanted resources. The benefit is that new custom resource definitions are automatically considered in the export.

Example configuration

summary: true # print a summary
progress: true # print progress
archive: true # create an archive
namespace: # define a single namespace (default all)
worker: 1 # define the number of parallel worker
excluded:
  kinds: # list all kinds to be excluded
