SNAP is a comprehensive container checkpointing and migration platform that enables you to capture, save, and restore running container states.
SNAP is an enterprise-grade container checkpointing and state management platform that revolutionizes how organizations handle container lifecycle management, disaster recovery, and application migration in Openshift environments.
SNAP enables organizations to capture the complete runtime state of running containers, convert them into portable images, and restore them across different environments.
Key Features:
Use Cases: Disaster recovery, application migration.
Capture the complete runtime state of running containers without downtime using Checkpoint/Restore in Userspace technology.
Create instant snapshots of application memory, file systems, and network connections for seamless state preservation.
Transform captured container checkpoints into standard container images that can be stored in any registry.
Convert runtime states into portable, deployable images for easy distribution and restoration across different environments.
Restore captured container states across different Kubernetes clusters, Openshift environments, and cloud platforms.
Enable seamless application migration and disaster recovery with complete state preservation.
Manage checkpointing operations across multiple Openshift clusters from a single interface.
Centralized configuration, monitoring, and automation for enterprise-scale deployments.
Built-in security features including role-based access control, audit logging, SSL/TLS encryption, and compliance reporting.
Meet enterprise security requirements for container state management.
Webhook system and Kubernetes operator integration enable event-driven automation.
Automate checkpoint creation, image pushing, and restoration workflows for CI/CD pipelines.
Red Hat certified products are tested to meet Red Hat’s criteria and supported as defined in the Red Hat Collaborative Support Process.
Partner validated products are tested by Red Hat Partners and supported as defined in the Red Hat Third Party Component Policy.
SNAP uses CRIU (Checkpoint/Restore in Userspace) technology:
1. Capture: Freezes the container and captures memory, processes, and file system state
2. Serialize: Converts the state into a portable format
3. Store: Saves the checkpoint as a tar file or container image
4. Restore: Recreates the exact container state from the checkpoint
- SnapWatcher: Operator that runs inside SnapAPI, monitors containers and performs automatic checkpointing
- SnapHook: Webhook system that provides event-driven automation and CI/CD integration
Yes, the cluster monitor DaemonSet is required for:
- Real-time cluster health monitoring
- Node-level configuration management
- Cluster status reporting
- Checkpointing capability verification
1. Navigate to Configuration > Registry
2. Add registry details (URL, credentials)
3. Test connectivity
4. Select the registry when configuring clusters
