Agent
Agent service provides a barebones HTTP and gRPC API and Service interface implementation for the development of the agent service.

| AGENT_CVM_GRPC_HOST | Agent service gRPC host | "" |
| AGENT_CVM_GRPC_PORT | Agent service gRPC port | 7001 |
| AGENT_CVM_GRPC_SERVER_CERT | Path to gRPC server certificate in pem format | "" |
| AGENT_CVM_GRPC_SERVER_KEY | Path to gRPC server key in pem format | "" |
| AGENT_CVM_GRPC_SERVER_CA_CERTS | Path to gRPC server CA certificate | "" |
| AGENT_CVM_GRPC_CLIENT_CA_CERTS | Path to gRPC client CA certificate | "" |
| AGENT_CVM_CA_URL | URL for CA service, if provided it will be used for certificate generation, used only with aTLS at the moment | "" |
| AGENT_CVM_ID | Unique identifier for the CVM (Confidential Virtual Machine) | "" |
| AGENT_CERTS_TOKEN | Authentication token for certificate service access | "" |
| AGENT_MAA_URL | Microsoft Azure Attestation service URL for Azure attestation | https://sharedeus2.eus2.attest.azure.net |
| AGENT_OS_BUILD | Operating system build information for attestation | UVC |
| AGENT_OS_DISTRO | Operating system distribution information for attestation | UVC |
| AGENT_OS_TYPE | Operating system type information for attestation | UVC |
Deployment
To start the service outside of the container, execute the following shell script:
# Download the latest version of the service
git clone git@github.com:ultravioletrs/cocos.git
cd cocos
# Compile the service
make agent
# Run the service
./build/cocos-agent
