If either the cert or key is not set, the server will use insecure transport.

MG_USERS_SERVER_CERT the path to server certificate in pem format.

MG_USERS_SERVER_KEY the path to the server key in pem format.

If either the cert or key is not set, the server will use insecure transport.

MG_THINGS_SERVER_CERT the path to server certificate in pem format.

MG_THINGS_SERVER_KEY the path to the server key in pem format.

Sometimes it makes sense to run Things as a standalone service to reduce network traffic or simplify deployment. This means that Things service operates only using a single user and is able to authorize it without gRPC communication with Auth service. When running Things in the standalone mode, Auth and Users services can be omitted from the deployment. To run service in a standalone mode, set MG_THINGS_STANDALONE_EMAIL and MG_THINGS_STANDALONE_TOKEN.

If you wish to secure the gRPC connection to Things and Users services you must define the CAs that you trust. This does not support mutual certificate authentication.

MG_HTTP_ADAPTER_CA_CERTS, MG_MQTT_ADAPTER_CA_CERTS, MG_WS_ADAPTER_CA_CERTS, MG_COAP_ADAPTER_CA_CERTS - the path to a file that contains the CAs in PEM format. If not set, the default connection will be insecure. If it fails to read the file, the adapter will fail to start up.

MG_THINGS_CA_CERTS - the path to a file that contains the CAs in PEM format. If not set, the default connection will be insecure. If it fails to read the file, the service will fail to start up.

By default, Magistrala will connect to Postgres using insecure transport. If a secured connection is required, you can select the SSL mode and set paths to any extra certificates and keys needed.

MG_USERS_DB_SSL_MODE the SSL connection mode for Users. MG_USERS_DB_SSL_CERT the path to the certificate file for Users. MG_USERS_DB_SSL_KEY the path to the key file for Users. MG_USERS_DB_SSL_ROOT_CERT the path to the root certificate file for Users.

MG_THINGS_DB_SSL_MODE the SSL connection mode for Things. MG_THINGS_DB_SSL_CERT the path to the certificate file for Things. MG_THINGS_DB_SSL_KEY the path to the key file for Things. MG_THINGS_DB_SSL_ROOT_CERT the path to the root certificate file for Things.

Supported database connection modes are: disabled (default), required, verify-ca and verify-full.

By default gRPC communication is not secure as Magistrala system is most often run in a private network behind the reverse proxy.

However, TLS can be activated and configured.
