* Add hash verification for datasets and algorithms Enhanced data integrity checking by incorporating hash fields in Dataset and Algorithm structures, and modified the corresponding service logic to validate these hashes during processing. The update includes SHA-3 for hash computation, replacing the former SHA-256 usage, and ensures the provided data matches the expected hash from the manifest to prevent processing malformed or corrupted data. - Introduce `Hash` field to both Dataset and Algorithm structs to store the expected hash value. - Implement SHA-3 hashing within service methods that process the data, ensuring consistency with newly added `Hash` fields. - Add error handling for hash mismatches, preventing further processing and alerting to potential data integrity issues. - Update Protocol Buffers serialization to accommodate the new hash fields for gRPC communication. - Modify manager service's Run method to pass the hash information when creating agent configurations. Go module dependencies were updated to include the new SHA-3 package and upgrade Go version to 1.21.6 for improved stability and compatibility. Signed-off-by: SammyOina <sammyoina@gmail.com> * Remove identifiers from protobuf and related code The protobuf definitions and related service handling code have been revised to drop specific identifier fields (`AlgorithmID` and `DatasetID`) to simplify API responses and internal function signatures. These removals streamline the overall data flow between components, reduce unnecessary data transmission, and lead to an aligned server-client expectation where identifiers are no longer a part of the response payload. Consequently, these changes simplify the logic within various functions and client commands, reinforcing encapsulation by ensuring that internal identifiers do not need to be managed or exposed unnecessarily.

Agent
Agent service provides a barebones HTTP and gRPC API and Service interface implementation for the development of the agent service.
Configuration
The service is configured using the environment variables from the following table. Note that any unset variables will be replaced with their default values.
| Variable | Description | Default |
|---|---|---|
| AGENT_LOG_LEVEL | Log level for agent service (debug, info, warn, error) | info |
| AGENT_GRPC_HOST | Agent service gRPC host | "" |
| AGENT_GRPC_PORT | Agent service gRPC port | 7002 |
| AGENT_GRPC_SERVER_CERT | Path to gRPC server certificate in pem format | "" |
| AGENT_GRPC_SERVER_KEY | Path to gRPC server key in pem format | "" |
| AGENT_GRPC_SERVER_CA_CERTS | Path to gRPC server CA certificate | "" |
| AGENT_GRPC_CLIENT_CA_CERTS | Path to gRPC client CA certificate | "" |
| COCOS_NOTIFICATION_SERVER_URL | Server to receive notification events from agent. | http:/localhost:9000 |
Deployment
To start the service outside of the container, execute the following shell script:
# download the latest version of the service
go get github.com/ultravioletrs/cocos
cd $GOPATH/src/github.com/ultravioletrs/cocos
# compile the agent
make agent
# set the environment variables and run the service
./build/cocos-agent
Usage
For more information about service capabilities and its usage, please check out the README documentation.
