Things

Things service provides an HTTP API for managing platform resources: devices, applications and channels. Through this API clients are able to do the following actions:

• provision new things (i.e. devices & applications)
• create new channels
• "connect" things into the channels

For an in-depth explanation of the aforementioned scenarios, as well as thorough understanding of Mainflux, please check out the official documentation.

Deployment

The service itself 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:
  things:
    image: mainflux/things:[version]
    container_name: [instance name]
    ports:
      - [host machine port]:[configured HTTP port]
    environment:
      MF_THINGS_DB_HOST: [Database host address]
      MF_THINGS_DB_PORT: [Database host port]
      MF_THINGS_DB_USER: [Database user]
      MF_THINGS_DB_PASS: [Database password]
      MF_THINGS_DB: [Name of the database used by the service]
      MF_THINGS_HTTP_PORT: [Service HTTP port]
      MF_THINGS_GRPC_PORT: [Service gRPC port]
      MF_USERS_URL: [Users service URL]
      MF_THINGS_SECRET: [String used for signing tokens]

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

# download the latest version of the service

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

# compile the things
make things

# copy binary to bin
make install

# set the environment variables and run the service
MF_THINGS_DB_HOST=[Database host address] MF_THINGS_DB_PORT=[Database host port] MF_THINGS_DB_USER=[Database user] MF_THINGS_DB_PASS=[Database password] MF_THINGS_DB=[Name of the database used by the service] MF_THINGS_HTTP_PORT=[Service HTTP port] MF_THINGS_GRPC_PORT=[Service gRPC port] MF_USERS_URL=[Users service URL] $GOBIN/mainflux-things
