Dejan Mijić ccd8965d6f Use PostgreSQL as primary persistence solution (#175)
* Use normalizer as stream source

Renamed 'writer' service to 'normalizer' and dropped Cassandra
facilities from it. Extracted the common dependencies to 'mainflux'
package for easier sharing. Fixed the API docs and unified environment
variables.

Manager

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

  • register new accounts and obtain access tokens
  • provision new clients (i.e. devices & applications)
  • create new channels
  • "connect" clients into the channels

For 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_DB_HOST Database host address localhost
MF_DB_PORT Database host port 5432
MF_DB_USER Database user mainflux
MF_DB_PASSWORD Database password mainflux
MF_MANAGER_DB Name of the database used by the service manager
MF_MANAGER_PORT Manager service HTTP port 8180
MF_MANAGER_SECRET string used for signing tokens manager

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:
  manager:
    image: mainflux/manager:[version]
    container_name: [instance name]
    ports:
      - [host machine port]:[configured HTTP port]
    environment:
      MF_DB_HOST: [Database host address]
      MF_DB_PORT: [Database host port]
      MF_DB_USER: [Database user]
      MF_DB_PASS: [Database password]
      MF_MANAGER_DB: [Name of the database used by the service]
      MF_MANAGER_PORT: [Service HTTP port]
      MF_MANAGER_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/cmd/manager

# compile the app; make sure to set the proper GOOS value
CGO_ENABLED=0 GOOS=[platform identifier] go build -ldflags "-s" -a -installsuffix cgo -o app

# set the environment variables and run the service
MF_DB_HOST=[Database host address] MF_DB_PORT=[Database host port] MF_DB_USER=[Database user] MF_DB_PASS=[Database password] MF_MANAGER_DB=[Name of the database used by the service] MF_MANAGER_PORT=[Service HTTP port] MF_MANAGER_SECRET=[String used for signing tokens] app

Usage
