 ## 0.6.0
 Starting in this version, the database schema is created through migrations
 instead of using the `reset_database.py` script. This means that for both the
 initial setup, as well as for upgrades, only the migrations have to be run.
 After updating and migrating, it is good practice to regenerate the SQL tile
 functions (`api/tools/prepare_sql_tiles.py`) as well. It doesn't matter if you
 do this when it is not required, so we've written a simple all-in-one update
 script that you can run to do all upgrade tasks. This is now in
 `api/tools/upgrade.py`.
 Please check [`UPGRADING.md`](./UPGRADING.md) for more details if you're
 upgrading an existing installation. It contains an important note for this
 upgrade in particular.
 ## 0.5.1
 Maintenance release, only includes build, deployment and documentation changes.
 ## 0.5.0

 * Project the whole track to the map, and show both versions
 * Log out of OpenID server when logging out of application
 * Convert speed units to km/h in frontend
 * Pages now have titles (#148)
 * Remove map from home page, it was empty anyway (#120)
 ### Internal

 * Add `LEAN_MODE` configuration to disable `road` database table usage and fall
  back to Overpass API for processing tracks (see
  [docs/lean-mode.md](docs/lean-mode.md)).
 * Read `config.overrides.py` file if it exists
 * Add osm2pgsql to portal image to be able to import OSM data from within the
  container
 * Fix path to roads_import.lua in docs
 * Explain to use the portal service, instead of api, in production
 * Use entrypoint instead of command, so you can run process_track.py one-off tasks
 ### Internals

 the migrations you need:

 ```
 ## Import OpenStreetMap data
 You need to import road information from OpenStreetMap for the portal to work.
 This information is stored in your PostgreSQL database and used when processing
 tracks (instead of querying the Overpass API), as well as for vector tile
 generation. The process applies to both development and production setups. For
 development, you should choose a small area for testing, such as your local
 county or city, to keep the amount of data small. For production use you have
 to import the whole region you are serving.
 * Install `osm2pgsql`. 
 * Download the area(s) you would like to import from [GeoFabrik](https://download.geofabrik.de). 
 * Import each file like this:
    ```bash
    osm2pgsql --create --hstore --style api/roads_import.lua -O flex \
      -H localhost -d obs -U obs \
      path/to/downloaded/myarea-latest.osm.pbf 
    ```
 You might need to adjust the host, database and username (`-H`, `-d`, `-U`) to
 your setup, and also provide the correct password when queried. For the
 development setup the password is `obs`. For production, you might need to
 expose the containers port and/or create a TCP tunnel, for example with SSH,
 such that you can run the import from your local host and write to the remote
 database.
 The import process should take a few seconds to minutes, depending on the area
 size. A whole country might even take one or more hours. You should probably
 not try to import `planet.osm.pbf`. 
 You can run the process multiple times, with the same or different area files,
 to import or update the data. However, for this to work, the actual [command
 line arguments](https://osm2pgsql.org/doc/manual.html#running-osm2pgsql) are a
 bit different each time, including when first importing, and the disk space
 required is much higher. 
 Refer to the documentation of `osm2pgsql` for assistance. We are using "flex
 mode", the provided script `api/roads_import.lua` describes the transformations
 and extractions to perform on the original data.

 ### Connecting to the PostgreSQL database
 If you need to connect to your development PostgreSQL database, you should
 install `psql` locally. The port 5432 is already forwarded, so you can connect with:
 ```
 psql -h localhost -U obs -d obs
 ```
 The password is `obs` as well.

+[README](./README.md).
 ## 0.8.1
 - Get the release in your source folder (``git pull; git checkout 0.8.0`` and update submodules ``git submodule update --recursive``)
 - Rebuild images ``docker-compose build``
 - No database upgrade is required, but tile functions need an update:
  ```bash
  docker-compose run --rm portal tools/prepare_sql_tiles.py
  ```
 - Start your portal and worker services. ``docker-compose up -d worker portal``
 ## 0.8.0
 Upgrade to `0.7.x` first. See below for details. Then follow these steps:
 > **Warning** The update includes a reprocessing of tracks after import. Depending on the number of tracks this can take a few hours. The portal is reachable during that time but events disappear and incrementally reappear during reimport.
 > **Info** With this version the import process for OpenStreetMap data has changed: the [new process](docs/osm-import.md) is easier on resources and finally permits to import a full country on a low-end VM.
 - Do your [usual backup](docs/production-deployment.md)
 - get the release in your source folder (``git pull; git checkout 0.8.0`` and update submodules ``git submodule update --recursive``)
 - Rebuild images ``docker-compose build``
 - Stop your portal and worker services ``docker-compose stop worker portal``
 - run upgrade
  ```bash
  docker-compose run --rm portal tools/upgrade.py
  ```
  this automatically does the following
  - Migration of database schema using alembic.
  - Upgrade of SQL tile schema to new schema.
  - Import the nuts-regions from the web into the database.
  - Trigger a re-import of all tracks.
 - Start your portal and worker services. ``docker-compose up -d worker portal``
 ## 0.7.0
 Upgrade to `0.6.x` first. See below for details. Then follow these steps:
 - Rebuild images
 - Stop your portal and worker services.
 - **Migration with alembic**: required 
 - **Prepare SQL Tiles**: required
 - Start your portal and worker services.
 - **Reimport tracks**: no action required 
 - **OSM Import**: required
 - **Config changes**: add `POSTGRES_MAX_OVERFLOW` and `POSTGRES_POOL_SIZE`
  variables, see `api/config.py.example`  
 ## 0.6.0
 **Make sure to upgrade to `0.5.1` first, by checking out that version tag and
 running migrations, then coming back to this version.** This is required
 because the migrations have been edited to create the initial database schema,
 but if you run the 0.5.1 migrations first, your database will remember that it
 already has all the tables created. This is not required if you set up a new
 installation.
 For this update, run these steps:
 - Build new images
 - Stop portal and worker services
 - Run the new upgrade tool:
  ```bash
  docker-compose run --rm portal tools/upgrade.py
  ```
 - Start portal and worker services
 ## 0.5.0
 The upgrade requires the following steps in the given order
 - Rebuild images
 - Stop your portal and worker services.
 - **Migration with alembic**: required 
 - **Prepare SQL Tiles**: required 
 - Start your portal and worker services.
 - **Reimport tracks**: required 
 - **OSM Import**: no action required
 - **Config changes**: none
 ## 0.4.1
 You can, but do not have to, reimport all tracks. This will generate a GPX file
 for each track and allow the users to download those. If a GPX file has not yet
 been created, the download will fail. To reimport all tracks, log in to your
 PostgreSQL database (instructions are in [README.md](./README.md) for
 development and [docs/production-deployment.md](./docs/production-deployment.md) for production)
 and run:
 ```sql
 UPDATE track SET processing_status = 'queued';
 ```
 You can do this selectively with `WHERE` statements.
 Make sure your worker is running to process the queue.
 ## 0.4.0
 * Rebuild your image, this may take longer than usual, as it will compile
  `osm2pgsql` for you. Next time, it should be in your docker build cache and
  be fast again.
 * Add new config flags: `VERBOSE`, `LEAN_MODE`, `POSTGRES_POOL_SIZE`,
  `POSTGRES_MAX_OVERFLOW`. Check the example config for sane default values.
 * Re-run `tools/prepare_sql_tiles.py` again (see README)
 * It has been made easier to import OSM data, check
  [docs/production-deployment.md](./docs/production-deployment.md) for the sections "Download
  OpenStreetMap maps" and "Import OpenStreetMap data". You can now download
  multiple .pbf files and then import them at once, using the docker image
  built with the `Dockerfile`. Alternatively, you can choose to enable [lean
  mode](docs/lean-mode.md). You do not need to reimport data, but setting this
  up now will make your life easier in the long run ;)
 ## v0.2 to v0.3 (MongoDB to PostgreSQL)
 * Shut down all services
 * Obviously, now is a good time to perform a full backup ;)
 * Update the codebase (`git pull`, `git submodule update`).
-* Update your ``docker-compose.yaml`` with the one from the ``deployment/examples``

 # Deploying an OpenBikeSensor Portal with Docker
 ## Introduction
 The main idea of this document is to provide an easy docker-based
 production-ready setup of the openbikesensor portal.  It uses the [the traefik
 proxy](https://doc.traefik.io/traefik/) as a reverse proxy, which listens
 on port 80 and 443.  Based on some labels, traefik routes the domains to the
 corresponding docker containers.
 ## Before Getting Started
 The guide and example configuration assumes one domain, which points to the
 server's IP address. This documentation uses `portal.example.com` as an
 example. The API is hosted at `https://portal.example.com/api`, while the main
 frontend is reachable at the domain root.
 ## Setup instructions
 ### Clone the repository
 First create a folder somewhere in your system, in the example we use 
 `/opt/openbikesensor` and export it as `$ROOT` to more easily refer to it.
 Clone the repository to `$ROOT/source`.
 ```bash
 export ROOT=/opt/openbikesensor
 mkdir -p $ROOT
 cd $ROOT
 git clone --recursive https://github.com/openbikesensor/portal source/
 # If you accidentally cloned without --recursive, fix it by running:
 # git submodule update --init --recursive
 ```
 Unless otherwise mentioned, commands below assume your current working
 directory to be `$ROOT`.
 ### Configure `traefik.toml`
 ```bash
 mkdir -p config/
 cp source/deployment/examples/traefik.toml config/traefik.toml
 vim config/traefik.toml
 ```
 Configure your email in the `config/traefik.toml`. This email is used by
 *Let's Encrypt* to send you some emails regarding your certificates.
 ### Configure `docker-compose.yaml`
 ```bash
 cp source/deployment/examples/docker-compose.yaml docker-compose.yaml
 vim docker-compose.yaml
 ```
 * Change the domain where it occurs, such as in `Host()` rules. 
 * Generate a secure password for the PostgreSQL database user. You will need to
  configure this in the application later.
 ### Create a keycloak instance
 Follow the [official guides](https://www.keycloak.org/documentation) to create
 your own keycloak server. You can run the keycloak in docker and include it in
 your `docker-compose.yaml`, if you like.
 Documenting the details of this is out of scope for our project. Please make
 sure to configure:
 * An admin account for yourself
 * A realm for the portal
 * A client in that realm with "Access Type" set to "confidential" and a
  redirect URL of this pattern: `https://portal.example.com/login/redirect`
 ### Prepare database
 Follow the procedure outlined in [README.md](../README.md) under "Prepare
 database".
 ### Import OpenStreetMap data
 Follow the procedure outlined in [README.md](../README.md) under "Import OpenStreetMap data".
 ### Configure portal
 ```bash
 cp source/api/config.py.example config/config.py
 ```
 Then edit `config/config.py` to your heart's content (and matching the
 configuration of the keycloak). Do not forget to generate a secure secret
 string.
 Also set `PROXIES_COUNT = 1` in your config, even if that option is not
 included in the example file. Read the 
 [Sanic docs](https://sanicframework.org/en/guide/advanced/proxy-headers.html) 
 for why this needs to be done. If your reverse proxy supports it, you can also
 use a forwarded secret to secure your proxy target from spoofing. This is not
 required if your application server does not listen on a public interface, but
 it is recommended anyway, if possible.
 ### Build container and run them
 ```bash
 docker-compose build portal
 docker-compose up -d portal
 ```
 ## Running a dedicated worker
 Extend your `docker-compose.yaml` with the following service:
 ```yaml
  worker:
    image: openbikesensor-portal
    build:
      context: ./source
    volumes:
      - ./data/api-data:/data
      - ./config/config.py:/opt/obs/api/config.py
    restart: on-failure
    links:
      - postgres
    networks:
      - backend
    command:
      - python
      - tools/process_track.py
 ```
 Change the `DEDICATED_WORKER` option in your config to `True` to stop
 processing tracks in the portal container. Then restart the `portal` service
 and start the `worker` service.
 ## Miscellaneous
 ### Logs
 To read logs, run
 ```bash
 docker-compose logs -f
 ```
 If something went wrong, you can reconfigure your config files and rerun:
 ```bash
 docker-compose build
 docker-compose up -d
 ```
 ### Updates
 Before updating make sure that you have properly backed-up your instance so you 
 can always roll back to a pre-update state.
 ### Backups
 To backup your instances private data you only need to backup the ``$ROOT`` folder.
 This should contain everything needed to start your instance again, no persistent
 data lives in docker containers. You should stop the containers for a clean backup.
 This backup contains the imported OSM data as well. That is of course a lot of
 redundant data, but very nice to have for a quick restore operation. If you
 want to generate smaller, nonredundant backups, or backups during live
 operation of the database, use a tool like `pg_dump` and extract only the
 required tables:
 * `overtaking_event`
 * `track`
 * `user` (make sure to reference `public.user`, not the postgres user table)
 * `comment`
 You might also instead use the `--exclude-table` option to ignore the `road`
 table only (adjust connection parameters and names):
 ```bash
 pg_dump -h localhost -d obs -U obs -n public -T road -f backup-`date +%F`.sql
 ```
 Also back up the raw uploaded files, i.e. the `local/api-data/tracks`
 directory. The processed data can be regenerated, but you can also back that
 up, from `local/api-data/processing-output`.
 Finally, make sure to create a backup of your keycloak instance. Refer to the
 keycloak documentation for how to export its data in a restorable way. This
 should work very well if you are storing keycloak data in the PostgreSQL and
 exporting that with an exclusion pattern instead of an explicit list.
 And then, please test your backup and restore strategy before going live, or at
 least before you need it!

 # Importing OpenStreetMap data
 The application requires a lot of data from the OpenStreetMap to work.
 The required information is stored in the PostgreSQL database and used when
 processing tracks, as well as for vector tile generation. The process applies
 to both development and production setups. For development, you should choose a
 small area for testing, such as your local county or city, to keep the amount
 of data small. For production use you have to import the whole region you are
 serving.
 ## General pipeline overview
 1. Download OpenStreetMap data as one or more `.osm.pbf` files.
 2. Transform this data to generate geometry data for all roads and regions, so
   we don't need to look up nodes separately. This step requires a lot of CPU
   and memory, so it can be done "offline" on a high power machine.
 3. Import the transformed data into the PostgreSQL/PostGIS database.
 ## Community hosted transformed data
 Since the first two steps are the same for everybody, the community will soon
 provide a service where relatively up-to-date transformed data can be
 downloaded for direct import. Stay tuned.
 ## Download data
 [GeoFabrik](https://download.geofabrik.de) kindly hosts extracts of the
 OpenStreetMap planet by region. Download all regions you're interested in from
 there in `.osm.pbf` format, with the tool of your choice, e. g.:
 ```bash
 wget -P local/pbf/ https://download.geofabrik.de/europe/germany/baden-wuerttemberg-latest.osm.pbf 
 ```
 ## Transform data
 To transform downloaded data, you can either use the docker image from a
 development or production environment, or locally install the API into your
 python environment. Then run the `api/tools/transform_osm.py` script on the data.
 ```bash
 api/tools/transform_osm.py baden-wuerttemberg-latest.osm.pbf baden-wuerttemberg-latest.msgpack
 ```
 In dockerized setups, make sure to mount your data somewhere in the container
 and also mount a directory where the result can be written. The development
 setup takes care of this, so you can use:
 ```bash
 docker-compose run --rm api tools/transform_osm.py \
  /pbf/baden-wuerttemberg-latest.osm.pbf /obsdata/baden-wuerttemberg-latest.msgpack
 ```
 Repeat this command for every file you want to transform.
 ## Import transformed data
 The command for importing looks like this:
 ```bash
 api/tools/import_osm.py baden-wuerttemberg-latest.msgpack
 ```
 This tool reads your application config from `config.py`, so set that up first
 as if you were setting up your application.
 In dockerized setups, make sure to mount your data somewhere in the container.
 Again, the development setup takes care of this, so you can use:
 ```bash
 docker-compose run --rm api tools/import_osm.py \
  /obsdata/baden-wuerttemberg-latest.msgpack
 ```
 The transform process should take a few seconds to minutes, depending on the area
 size. You can run the process multiple times, with the same or different area
 files, to import or update the data. You can update only one region and leave
 the others as they are, or add more filenames to the command line to
 bulk-import data.
 ## How this works
 * The transformation is done with a python script that uses
  [pyosmium](https://osmcode.org/pyosmium/) to read the `.osm.pbf` file. This
  script then filters the data for only the required objects (such as road
  segments and administrative areas), and extracts the interesting information
  from those objects.
 * The node geolocations are looked up to generate a geometry for each object.
  This requires a lot of memory to run efficiently.
 * The geometry is projected to [Web Mercator](https://epsg.io/3857) in this
  step to avoid continous transformation when tiles are generated later. Most
  operations will work fine in this projection. Projection is done with the
  [pyproj](https://pypi.org/project/pyproj/) library.
 * The output is written to a binary file in a very simple format using
  [msgpack](https://github.com/msgpack/msgpack-python), which is way more
  efficient that (Geo-)JSON for example. This format is stremable, so the
  generated file is never fully written or read into memory.
 * The import script reads the msgpack file and sends it to the database using
  [psycopg](https://www.psycopg.org/). This is done because it supports
  PostgreSQL's `COPY FROM` statement, which enables much faster writes to the
  database that a traditionional `INSERT VALUES`. The file is streamed directly
  to the database, so it is never read into memory.

 # Deploying an OpenBikeSensor Portal with Docker
 ## Introduction
 The main idea of this document is to provide an easy docker-based
 production-ready setup of the openbikesensor portal.  It uses the [the traefik
 proxy](https://doc.traefik.io/traefik/) as a reverse proxy, which listens
 on port 80 and 443.  Based on some labels, traefik routes the domains to the
 corresponding docker containers.
 ## Requirements
 This guide requires a Linux-system, where `docker` and `docker-compose` are installed.
 Ensure, that your system is up to date.
 > TODO
 ```bash
 apt install docker.io docker-compose pwgen
 ```
 ## Before Getting Started
 The example configurations assume two domains, which points to the
 server's IP address. This documentation uses `portal.example.com` and
 `login.example.com`. The API is hosted at `https://portal.example.com/api`, 
 while the main frontend is reachable at the domain root.
 ## Setup instructions
 First of all, login into your system via SSH.
 ### Create working directory
 Create a folder somewhere in your system, in this guide we use 
 `/opt/openbikesensor`:
 ```bash
 mkdir /opt/openbikesensor
 ```
 ### Clone the repository
 Clone the repository to `/opt/openbikesensor/`:
 ```bash
 cd /opt/openbikesensor/
 git clone --recursive https://github.com/openbikesensor/portal source/
 # If you accidentally cloned without --recursive, fix it by running:
 # git submodule update --init --recursive
 ```
 ### Copy predefined configuration files
 ```bash
 mkdir -p /opt/openbikesensor/config
 cd /opt/openbikesensor/
 cp -r source/deployment/config source/deployment/docker-compose.yaml source/deployment/.env .
 ```
 ### Create a Docker network
 ```bash
 docker network create gateway
 ```
 ### Traefik
 #### Configure `traefik.toml`
 ```bash
 cd /opt/openbikesensor/
 nano config/traefik.toml
 ```
 Configure your email in the `config/traefik.toml`. This email is used by
 *Let's Encrypt* to send you some emails regarding your certificates.
 #### Start Traefik
 ```bash
 cd /opt/openbikesensor/
 docker-compose up -d traefik
 docker-compose logs -f traefik
 ```
 > traefik_1            | time="2022-01-03T13:02:36Z" level=info msg="Configuration loaded from file: /traefik.toml"
 ### Generate passwords
 Generate three passords, for example with `pwgen`:
 ```bash
 pwgen -n 20
 ```
 They will be uses in the next steps.
 ### KeyCloak
 #### Configure `.env`
 ```bash
 cd /opt/openbikesensor/
 nano .env
 ```
 Configure:
 * `OBS_KEYCLOAK_URI`:
    * The subdomain of your keycloak
 * `OBS_KEYCLOAK_POSTGRES_PASSWORD`
    * One of the generated passwords for the KeyCloak-postgres
 * `OBS_KEYCLOAK_ADMIN_PASSWORD`:
    * One of the generated passwords for the KeyCloak-admin
 * `OBS_KEYCLOAK_PORTAL_REDIRECT_URI`:
    * The Redirect URI, e.g. the subdomain of your portal (ensure, it ends with `/*`)
 #### Start KeyCloak
 ```bash
 docker-compose up -d keycloak
 docker-compose logs -f keycloak
 ```
 Wait until postgres and keycloak are started:
 > keycloak_1           | 13:08:55,558 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://127.0.0.1:9990
 Open:
 * https://login.example.com/
 * Test login to the admin console with your admin account
 #### Configure Realm and Client
 Jump into the KeyCloak container:
 ```bash
 docker-compose exec keycloak /bin/bash
 ```
 Since we configured the `.env`-file we can run the following commands
 to create a realm and a client now:
 ```bash
 # Login
 /opt/jboss/keycloak/bin/kcadm.sh config credentials --server http://localhost:8080/auth --realm master --user $KEYCLOAK_USER --password $KEYCLOAK_PASSWORD
 # Create Realm
 /opt/jboss/keycloak/bin/kcadm.sh create realms -s realm=$OBS_KEYCLOAK_REALM -s enabled=true -o
 # Create a client and remember the unique id of the client
 CID=$(/opt/jboss/keycloak/bin/kcadm.sh create clients -r $OBS_KEYCLOAK_REALM -s clientId=portal -s "redirectUris=[\"$OBS_KEYCLOAK_PORTAL_REDIRECT_URI\"]" -i)
 # Create a secret for the client
 /opt/jboss/keycloak/bin/kcadm.sh create clients/$CID/client-secret -r $OBS_KEYCLOAK_REALM
 # Get the secret of the client
 /opt/jboss/keycloak/bin/kcadm.sh get clients/$CID/client-secret -r $OBS_KEYCLOAK_REALM
 ```
 Exit the container with `exit`. Configure the client secret:
 ```bash
 cd /opt/openbikesensor/
 nano .env
 ```
 Configure:
 * `OBS_KEYCLOAK_CLIENT_SECRET`:
    *  Use the obtained client secret
 #### Create a user
 * Login into your Keycloak with the admin user and select the realm obs
 * Create a user with username and email for the realm `obs` (*Hint*: email is required by the portal)
 * Configure a password in the tab `Credentials` as well
 ### Portal
 #### Configure Postgres
 ```bash
 cd /opt/openbikesensor/
 nano .env
 ```
 Configure:
 * `OBS_POSTGRES_HOST`:
    * The should be the postgres-container, e.g. `postgres`
 * `OBS_POSTGRES_USER`:
    * The default postgres-user is `obs`
 * `OBS_POSTGRES_PASSWORD`:
    * Use one of the generated passwords for the postgres
 * `OBS_POSTGRES_DB`:
    * The default postgres-database is `obs`
 * `OBS_POSTGRES_URL`:
    * Use the same informations as aboe to configure the `POSTGRES_URL`, 
      this one is used by the portal.
 #### Start Postgres for the portal
 ```
 cd /opt/openbikesensor/
 docker-compose up -d postgres
 docker-compose logs -f postgres
 ```
 Wait until started:
 > postgres_1           | PostgreSQL init process complete; ready for start up.
 #### Build the portal image
 ```bash
 cd /opt/openbikesensor/
 docker-compose build portal
 ```
 *Hint*: This may take up to 10 minutes. In the future, we will provide a prebuild image.
 #### Prepare database
 Run the following scripts to prepare the database:
 ```bash
 docker-compose run --rm portal tools/upgrade.py
 ```
 For more details, see [README.md](../README.md) under "Prepare database".
 #### Import OpenStreetMap data
 Follow [these instructions](./osm-import.md).
 #### Configure portal
 The portal can be configured via env-vars or via the `config.py`. 
 It's important to know, that the `config.py` overrides the env-vars.
 All env-vars start with `OBS_` and will be handled by the application without the prefix.
 For example, the env-var `OBS_SECRET` will be same as `SECRET` within the `config.py` and will be `SECRET` within the application.
 ```bash
 cd /opt/openbikesensor/
 nano .env
 ```
 Configure:
 * `OBS_PORTAL_URI`:
    * The subdomain of your portal
 * `OBS_SECRET`:
    * Generate a UUID with `uuidgen` and use it as the secret
 * `OBS_POSTGRES_URL`:
    * Should be configured already
 * `OBS_KEYCLOAK_URL`:
    * You can find it as the `issuer`, when you click on *OpenID Endpoint Configuration* in the realm obs
 * `OBS_KEYCLOAK_CLIENT_SECRET`:
    * Should be configured already
 * `OBS: DEDICATED_WORKER`
    * Should be set to `"True"`, since it the workder will be started with the portal
 * `OBS_DATA_DIR`
    * The data dir must be the same for the portal and the worer. 
      The default is `/data` within the containers
 * `OBS_PROXIES_COUNT`:
    * This sets `PROXIES_COUNT = 1` in your config
    * Read the [Sanic docs](https://sanicframework.org/en/guide/advanced/proxy-headers.html) 
      for why this needs to be done. If your reverse proxy supports it, you can also
      use a forwarded secret to secure your proxy target from spoofing. This is not
      required if your application server does not listen on a public interface, but
      it is recommended anyway, if possible.
 Have a look into the `config.py`, which other variables may affect you.
 #### Start the portal
 ```bash
 cd /opt/openbikesensor/
 docker-compose up -d portal
 docker-compose logs -f portal worker
 ```
 > portal_1             | [2022-01-03 13:37:48 +0000] [1] [INFO] Goin' Fast @ http://0.0.0.0:3000
 This also starts a dedicated worker container to handle the tracks.
 #### Test the portal
 * Open: https://portal.example.com/ (URL depends on your setup)
 * Login with the user
 * Upload a track via My Tracks
 You should see smth. like:
 > worker_1             | INFO: Track uuqvcvlm imported.
 When you click on *My Tracks*, you should see it on a map.
 #### Configure the map position
 Open the tab *Map** an zoom to the desired position. The URL contains the corresponding GPS position,
 for example:
 > 14/53.86449349032097/10.696108517499198
 Configure the map position in the `config.py` and restart the portal, by setting `mapHome` in the variable `FRONTEND_CONFIG`:
 ```
 cd /opt/openbikesensor/
 nano config/config.py 
 docker-compose restart portal
 ```
 **Hint**: Maybe it's required to disable the browser cache to see the change.
 The tab *Map* should be the selected map section now.
 When you uploaded some tracks, you map should show a colors overlay on the streets.
 ## Miscellaneous
 ### Logs
 To read the logs, run
 ```bash
 docker-compose logs -f
 ```
 If something went wrong, you can reconfigure your config files and rerun:
 ```bash
 docker-compose up -d
 ```
 ### Updates
 Before updating make sure that you have properly backed-up your instance so you 
 can always roll back to a pre-update state.
 #### Migrating
 Migrations are done with
 [Alembic](https://alembic.sqlalchemy.org/en/latest/index.html), please refer to
 its documentation for help. Most of the time, running this command will do all
 the migrations you need:
 ```bash
 docker-compose run --rm portal alembic upgrade head
 ```
 You are advised to create a backup (see below) before running a migration, and
 to shut down the services before the migration and start them afterwards.
 ### Backups
 To backup your instances private data you only need to backup the ``$ROOT`` folder.
 This should contain everything needed to start your instance again, no persistent
 data lives in docker containers. You should stop the containers for a clean backup.
 This backup contains the imported OSM data as well. That is of course a lot of
 redundant data, but very nice to have for a quick restore operation. If you
 want to generate smaller, nonredundant backups, or backups during live
 operation of the database, use a tool like `pg_dump` and extract only the
 required tables:
 * `road_usage`
 * `overtaking_event`
 * `track`
 * `user` (make sure to reference `public.user`, not the postgres user table)
 * `comment`
 You might also instead use the `--exclude-table` option to ignore the `road`
 table only (adjust connection parameters and names):
 ```bash
 pg_dump -h localhost -d obs -U obs -n public -T road -f backup-`date +%F`.sql
 ```
 Also back up the raw uploaded files, i.e. the `local/api-data/tracks`
 directory. The processed data can be regenerated, but you can also back that
 up, from `local/api-data/processing-output`.
 Finally, make sure to create a backup of your keycloak instance. Refer to the
 keycloak documentation for how to export its data in a restorable way. This
 should work very well if you are storing keycloak data in the PostgreSQL and
 exporting that with an exclusion pattern instead of an explicit list.
 And then, please test your backup and restore strategy before going live, or at
 least before you need it!
 ### Connecting to the PostgreSQL database
 Here are the quick steps for connecting to your PostgreSQL database, should you
 need that:
 * Add the `gateway` network to your `postgres` service.
 * Add a port forwarding to your `postgres` service:
  ```yaml
     ports:
       - 127.0.0.1:25432:5432
  ```
 * Run `docker-compose up -d postgres` again
 * You can now connect from your server to the PostgreSQL service with:
  ```
  psql -h localhost -U obs -d obs -p 25432
  ```
  You will need your database password for the connection.
 * If you do not want to install `psql` outside your container, you can use an
  SSH tunnel from your local machine to your server and run `psql` locally.
