# Olsztyńskie Autobusy

## About

Olsztyńskie Autobusy combine harvesting vehicles data from systems of Olsztyn public transportation agency, serving current data for web app users and retaining that data.

[![Screenshot](screenshot.png "https://autobusy.olsztyn.pl")](https://autobusy.olsztyn.pl)

It has modular microservice architecture divided into front/back-end.

Main part of this infrastructure is the _dataharvester_ service and a Postgres instance.

## Build & Run

In order to start a dockerized instance locally, you need to obtain session cookie and build services from source.

This walk-through assumes you have Go & Docker installed and configured.

Clone repository:

```

git clone [email protected]:amwolff/oa.git $GOPATH/src/github.com/amwolff/oa

```

Install dependencies:

```

curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh

cd $GOPATH/src/github.com/amwolff/oa

dep ensure

```

Get session cookie:

1. In browser navigate to `sip.zdzit.olsztyn.eu`;

2. Open up inspector (Google Chrome: Control+Shift+I) > Application > Storage > Cookies;

3. Copy value of ASP.NET_SessionId cookie.

Configure services:

In files

```

# $GOPATH/src/github.com/amwolff/oa/deploy/services/dataharvester/example_config.yml

Line 3: ClientCookie: 

# $GOPATH/src/github.com/amwolff/oa/deploy/services/pinger/Dockerfile

Line 3: ENV CLIENT_COOKIE 

```

substitue `` for copied value of your session cookie.

Build everything:

```

cd $GOPATH/src/github.com/amwolff/oa/deploy

./build_all.sh -d -v 63d0d1c

```

Start services:

```

docker network create backend

docker network create frontend

docker run -d --name oa_db --network backend --network-alias oa-postgres-ip-alias --rm amwolff/oa:oadb_63d0d1c

docker run -d --name oa_pinger --network backend --rm amwolff/oa:pinger_63d0d1c

docker run -d --name oa_dataharvester --network backend --rm amwolff/oa:dataharvester_63d0d1c

docker run -d --name oa_api --network backend -p 8080:80 --rm amwolff/oa:api_63d0d1c

docker network connect frontend oa_api

docker run -d --name oa_dirserver --network frontend -p 80:80 --rm amwolff/oa:dirserver_63d0d1c

```

The app should be now available at `http://localhost`.

### Notes

Started instance is very similar to what I deployed in cloud for "production" use.

Additionally, I've used docker-compose along with Docker in swarm mode (to encapsulate startup instructions) and traefik (for requests routing).
