Installation

Go Install

go install github.com/chaoscypher/kube-save-restore@latest

Building from Source

1. Clone the repository:

   git clone git@github.com:ChaosCypher/kube-save-restore.git

2. Navigate to the project directory:

   cd kube-save-restore

3. Build the binary:

   go build -o kube-save-restore

4. Move the binary to your PATH:

   sudo mv kube-save-restore /usr/local/bin/

5. Run the binary:

   kube-save-restore --help

Usage

kube-save-restore offers two primary modes: backup and restore.

Backup

To create a backup of your Kubernetes resources:

./kube-save-restore --mode=backup --backup-dir=/path/to/backup --dry-run=false --log-level=info

This command will backup all supported resources from all namespaces in your cluster.

Restore

To restore your Kubernetes resources from a backup:

./kube-save-restore --mode=restore --restore-dir=/path/to/backup --dry-run=true --log-level=debug

It's recommended to use the --dry-run=true flag first to verify the restore operation before applying changes.

Additional Options

• Use --context to specify a different Kubernetes context.
• Set --log-file to save logs to a file instead of stdout.
• Adjust --log-level to control the verbosity of logging.

For a full list of options, run:

./kube-save-restore --help

Configuration

kube-save-restore can be configured using command-line flags or environment variables:

Flag	Environment Variable	Description
--kubeconfig	KUBECONFIG	Path to the kubeconfig file
--context	KUBE_CONTEXT	Kubernetes context to use
--backup-dir	BACKUP_DIR	Directory where backups will be stored
--restore-dir	RESTORE_DIR	Directory from where backups will be restored
--mode	MODE	Operation mode: backup or restore
--dry-run	DRY_RUN	Execute a dry run without making any changes
--log-level	LOG_LEVEL	Logging level: debug, info, warn, error
--log-file	LOG_FILE	Path to the log file

Environment variables take precedence over command-line flags.
