# Message normalizer
|
|
|
|
Normalizer service consumes events published by adapters, normalizes SenML-formatted
|
|
ones, and publishes them to the post-processing stream.
|
|
|
|
## 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_NATS_URL | NATS instance URL | nats://localhost:4222 |
|
|
| MF_NORMALIZER_PORT | Normalizer service HTTP port | 8180 |
|
|
|
|
## 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:
|
|
normalizer:
|
|
image: mainflux/normalizer:[version]
|
|
container_name: [instance name]
|
|
environment:
|
|
MF_NATS_URL: [NATS instance URL]
|
|
MF_NORMALIZER_PORT: [Service HTTP port]
|
|
```
|
|
|
|
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 app; make sure to set the proper GOOS value
|
|
make normalizer
|
|
|
|
# copy binary to bin
|
|
make install
|
|
|
|
# set the environment variables and run the service
|
|
MF_NATS_URL=[NATS instance URL] MF_NORMALIZER_PORT=[Service HTTP port] $GOBIN/mainflux-normalizer
|
|
```
