b1ackd0t a0c40ba462 NOISSUE - Update Copyright Notice (#39)
* chore(license): update copyright notices

Add CI check for non go files to check that the files contain a license

* fix(ci): log failed files

When the CI fails during check for license header, log the failed file to console so that someone can check on the actual file. Also simplify the grep check to make it more human readable and understandable

Magistrala CoAP adapter provides an CoAP API for sending messages through the platform.

Configuration

The service is configured using the environment variables presented in the following table. Note that any unset variables will be replaced with their default values.

Variable Description Default
MG_COAP_ADAPTER_LOG_LEVEL Service log level info
MG_COAP_ADAPTER_HOST CoAP service listening host
MG_COAP_ADAPTER_PORT CoAP service listening port 5683
MG_COAP_ADAPTER_SERVER_CERT CoAP service server certificate
MG_COAP_ADAPTER_SERVER_KEY CoAP service server key
MG_COAP_ADAPTER_HTTP_HOST Service HTTP listening host
MG_COAP_ADAPTER_HTTP_PORT Service listening port 5683
MG_COAP_ADAPTER_HTTP_SERVER_CERT Service server certificate
MG_COAP_ADAPTER_HTTP_SERVER_KEY Service server key
MG_THINGS_AUTH_GRPC_URL Things service Auth gRPC URL localhost:7000
MG_THINGS_AUTH_GRPC_TIMEOUT Things service Auth gRPC request timeout in seconds 1s
MG_THINGS_AUTH_GRPC_CLIENT_TLS Flag that indicates if TLS should be turned on false
MG_THINGS_AUTH_GRPC_CA_CERTS Path to trusted CAs in PEM format
MG_MESSAGE_BROKER_URL Message broker instance URL nats://localhost:4222
MG_JAEGER_URL Jaeger server URL http://jaeger:14268/api/traces

MG_COAP_ADAPTER_INSTANCE_ID CoAP adapter instance ID

Deployment

The service itself is distributed as Docker container. Check the coap-adapter service section in docker-compose to see how service is deployed.

Running this service outside of container requires working instance of the message broker service. To start the service outside of the container, execute the following shell script:

# download the latest version of the service
git clone https://github.com/absmach/magistrala

cd magistrala

# compile the http
make coap

# copy binary to bin
make install

# set the environment variables and run the service

Usage

If CoAP adapter is running locally (on default 5683 port), a valid URL would be: coap://localhost/channels/<channel_id>/messages?auth=<thing_auth_key>. Since CoAP protocol does not support Authorization header (option) and options have limited size, in order to send CoAP messages, valid auth value (a valid Thing key) must be present in Uri-Query option.
