HTTP adapter

HTTP adapter provides an HTTP 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
MF_HTTP_ADAPTER_LOG_LEVEL Log level for the HTTP Adapter error
MF_HTTP_ADAPTER_PORT Service HTTP port 8180
MF_NATS_URL NATS instance URL nats://localhost:4222
MF_THINGS_URL Things service URL localhost:8181
MF_HTTP_ADAPTER_CLIENT_TLS Flag that indicates if TLS should be turned on false
MF_HTTP_ADAPTER_CA_CERTS Path to trusted CAs in PEM format

Deployment

The service is distributed as Docker container. The following snippet provides a compose file template that can be used to deploy the service container locally:

version: "2"
services:
  adapter:
    image: mainflux/http:[version]
    container_name: [instance name]
    ports:
      - [host machine port]:8180
    environment:
      MF_THINGS_URL: [Things service URL]
      MF_NATS_URL: [NATS instance URL]
      MF_HTTP_ADAPTER_LOG_LEVEL: [HTTP Adapter Log Level]
      MF_HTTP_ADAPTER_PORT: [Service HTTP port]
      MF_HTTP_ADAPTER_CA_CERTS: [Path to trusted CAs in PEM format]

To start the service outside of the container, execute the following shell script:

# download the latest version of the service
go get github.com/mainflux/mainflux

cd $GOPATH/src/github.com/mainflux/mainflux

# compile the http
make http

# copy binary to bin
make install

# set the environment variables and run the service
MF_THINGS_URL=[Things service URL] MF_NATS_URL=[NATS instance URL] MF_HTTP_ADAPTER_LOG_LEVEL=[HTTP Adapter Log Level] MF_HTTP_ADAPTER_PORT=[Service HTTP port] MF_HTTP_ADAPTER_CA_CERTS=[Path to trusted CAs in PEM format] $GOBIN/mainflux-http

Setting MF_HTTP_ADAPTER_CA_CERTS expects a file in PEM format of trusted CAs. This will enable TLS against the Things gRPC endpoint trusting only those CAs that are provided.

Usage
