Pv Migrate
This tool is a command-line utility designed for managing the lifecycle of persistent storage within containerized environments. It facilitates the migration, backup, and restoration of data between persistent volume claims across different namespaces, clusters, or storage classes. By automating these tasks, it supports infrastructure scaling, disaster recovery, and general storage administration.
The project distinguishes itself through its orchestration of ephemeral jobs that execute data transfers in the background, ensuring operations continue even if the client session is disconnected. It employs a pluggable transfer strategy that allows users to select specific synchronization methods to accommodate varying network topologies, firewall restrictions, and bandwidth constraints. The tool also supports reverse migration for environments where the source cannot initiate external connections.
Beyond core migration, the utility provides granular control over data movement, including the ability to synchronize specific subdirectories and customize resource manifests to meet infrastructure requirements. It enforces security policies by applying restricted security contexts and non-root execution to migration containers. Once tasks are complete, the tool automatically cleans up temporary cluster resources to maintain environment integrity.
Features
- Kubernetes Data Migrators - Ships a command-line interface for migrating persistent storage data between Kubernetes environments using configurable transfer strategies.
- Local Persistent Volume Managers - Facilitates seamless data transfers between persistent storage claims across namespaces, clusters, or storage classes.
- Kubernetes Volume Management - Provides comprehensive lifecycle management for persistent volumes, including migration, backup, and restoration across Kubernetes environments.
- Restoration Utilities - The tool populates persistent storage with previously archived data from object storage to recover system states or initialize new storage environments.
- Ephemeral Job Runners - Orchestrates data transfer tasks as isolated, ephemeral Kubernetes jobs within the cluster.
- Volume Copies and Migrations - Moves data between storage claims across different namespaces, clusters, or storage classes.
- Persistent Volume Backups and Restores - Archives persistent volume data to remote object storage for long-term retention and disaster recovery.
- System Data Backup Schedules - Automates recurring data transfers to remote storage on a fixed timetable.
- Disaster Recovery Workflows - Backs up persistent volume data to remote object storage to ensure data preservation and rapid recovery.
- Migration Reversion - Supports pushing data from source to destination to bypass network restrictions on incoming connections.
- Persistent Storage Management - Manages the lifecycle of persistent storage through automated synchronization and migration tasks between different storage classes.
- Pluggable Transfer Strategies - Provides pluggable transfer strategies to select optimal synchronization methods based on network and storage constraints.
- Cloud Native Data Management Tools - Automates the transfer, archival, and restoration of persistent storage contents within containerized environments.
- Infrastructure Migration Tools - The tool enables modification of generated resource definitions to adjust container images, affinity rules, or hardware settings during the automated migration process.
- Sidecar Containers - Deploys transient sidecar containers to facilitate direct data movement between persistent volumes.
- Background Task Execution - Executes long-running data migration tasks in the background to ensure completion despite client disconnection.
- Background Job Monitoring - Provides real-time status tracking and progress monitoring for detached background migration operations.
- Kubernetes Persistent Volume Backups - Facilitates the backup and restoration of persistent volume data to ensure disaster recovery and data preservation.
