# 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][doc].
|
|
|
|

|
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.

## 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:
|
|
|
|
```yaml
|
|
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:
|
|
|
|
```bash
|
|
# 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
|
|
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
|
|
```
