Krew Plugin Usage

If you’re using KubeSnapIt via Krew as a kubectl plugin (Linux/macOS), here are the usage examples to help you manage your Kubernetes resources effectively.

Ensure you are connected to your Kubernetes cluster before using KubeSnapIt. You can use kubectl commands to check your connection and manage your contexts.

Parameters

Parameter Description
-Namespace Specifies the namespace to snapshot or restore.
-AllNamespaces Captures or restores all namespaces. Overrides the -Namespace parameter.
-AllNonSystemNamespaces Capture all non-system namespaces. If this is provided, -Namespace and -AllNamespaces will be ignored.
-OutputPath Path to save the snapshot files.
-InputPath Path to restore snapshots from or for comparison.
-ComparePath Path to the second snapshot for comparison.
-Labels Filters Kubernetes objects based on specified labels (e.g., app=nginx).
-Objects Comma-separated list of specific objects in the kind/name format.
-DryRun Simulates snapshotting or restoring without making any actual changes.
-Restore Restores resources from the specified snapshot path.
-Compare Compares two snapshots or a snapshot with the current cluster state.
-CompareWithCluster Compares a snapshot with the current cluster state.
-Force Bypasses confirmation prompts when restoring snapshots.
-Verbose Shows detailed output during the snapshot, restore, or comparison process.
-SnapshotHelm Backup Helm releases and their values.
-Help Displays the help information for using KubeSnapIt.

Taking a Snapshot

To capture a snapshot of Kubernetes resources in a specific namespace:

kubectl KubeSnapIt --namespace "your-namespace" --output-path "./snapshots"

To capture snapshots of all resources across all namespaces:

kubectl KubeSnapIt --all-namespaces --output-path "./snapshots"

To capture snapshots of all non-system namespaces

kubectl kubesnapit -allnonsystemnamespaces -outputpath ./snapshots

To capture snapshots with specific labels

kubectl kubesnapit -namespace my-namespace -labels app=nginx -outputpath ./snapshots

To capture snapshots of specific objects

kubectl kubesnapit -namespace my-namespace -objects pod/my-pod,deployment/my-deployment -outputpath ./snapshots

Snapshotting Helm Releases

To capture snapshots of Helm releases in a specific namespace

kubectl kubesnapit -backuphelm -namespace my-namespace -outputpath ./helm-backups

To capture snapshots of Helm releases in all namespaces

kubectl kubesnapit -backuphelm -allnamespaces -outputpath ./helm-backups

To capture snapshots of Helm releases in all non-system namespaces

kubectl kubesnapit -backuphelm -allnonsystemnamespaces -outputpath ./helm-backups

Comparing Snapshots

To compare a local snapshot against the live cluster state:

kubectl kubesnapit -comparewithcluster -inputpath ./snapshots

To compare two local snapshots:

kubectl kubesnapit -comparesnapshots -inputpath ./snapshots/snapshot1 -comparepath ./snapshots/snapshot2

Resource Restoration

To restore a Kubernetes resource from a snapshot using kubectl KubeSnapIt, use the following command. By default, this will ask for confirmation before restoring:

kubectl KubeSnapIt restore --input-path "./snapshots/your_snapshot.yaml"

Skipping Confirmation with --force

If you want to bypass the confirmation prompt and restore the resources immediately, use the --force option:

kubectl KubeSnapIt restore --input-path "./snapshots/your_snapshot.yaml" --force

This command restores the resources from the specified snapshot without asking for confirmation.

Dry Run Mode

Use the --dry-run option to simulate snapshotting or restoration processes without making any actual changes:

kubectl KubeSnapIt --namespace "your-namespace" --output-path "./snapshots" --dry-run
