Depot is a content-addressable storage solution specifically designed for container images. It leverages the concept of content-addressing, where data is uniquely identified by its hash, ensuring data integrity and immutability:

Key Features:

• Content-Addressable Storage: Stores container image content (layers) with unique identifiers based on their content, not names or locations.

• Immutable Data: Once stored, image content cannot be modified, guaranteeing image integrity and reproducibility.

• Efficient Sharing and Distribution: Content can be shared and distributed efficiently based on its content identifiers, avoiding redundant downloads.

• Garbage Collection: Automatically removes unused content based on usage data, optimizing storage utilization.

• Integration with containerd: Seamlessly integrates with the containerd runtime for managing and deploying content-addressed images.

Benefits of Using Depot:

• Enhanced Security: Ensures image integrity and reduces vulnerabilities by immutably storing image content.

• Improved Efficiency: Optimizes storage and distribution by eliminating redundant downloads of identical content.

• Reproducible Builds: Guarantees consistency across environments by referencing content uniquely by its hash.

• Scalability: Efficiently handles large volumes of container image content in cloud-native deployments.
