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.
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_THINGS_DB_HOST | Database host address | localhost |
MF_THINGS_DB_PORT | Database host port | 5432 |
MF_THINGS_DB_USER | Database user | mainflux |
MF_THINGS_DB_PASS | Database password | mainflux |
MF_THINGS_DB | Name of the database used by the service | things |
MF_THINGS_HTTP_PORT | Things service HTTP port | 8180 |
MF_THINGS_GRPC_PORT | Things service gRPC port | 8181 |
MF_USERS_URL | Users service URL | localhost:8181 |
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
go get github.com/mainflux/mainflux
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
