Upgrading

This document describes the general steps to upgrade between major changes. Simple migrations, e.g. for adding schema changes, are not documented explicitly. Their general usage is described in the README (for development) and deployment/README.md (for production).

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:
    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 for development and deployment/README.md for production) and run:

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 deployment/README.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. 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 folder.

    • Leave the MongoDB service in place for now.
    • Update all other service descriptions.
    • You can remove redis already.
    • Generate a better password than the default for your postgres user.
    • Traefik rules have been simplified as all routes are handled by the portal service now.
  • Start up the mongo and postgres services. Wait for postgres to finish initializing (see README).

  • Build the new image (e.g. with docker-compose build portal)

  • Configure your API. The example config file is api/config.py.example, and it will need to be mounted to api/config.py in the container. Ignore the Keycloak options for now.

  • Prepare the database:

    docker-compose run --rm portal python tools/reset_database.py
    docker-compose run --rm portal python tools/prepare_sql_tiles.py
    
  • Import OSM data (see README).

  • Run the database migration script:

    docker-compose run --rm \
        -v $PWD/export:/export \
        portal \
        python tools/import_from_mongodb.py mongodb://mongo/obs \
        --keycloak-users-file /export/users.json
    

    There is an option --keep-api-keys which means the users won't have to reconfigure the devices they used their API key in. However, please try to avoid this option if at all possible, as the old keys are very insecure. The default without this option to generate a new, secure API key for each user.

  • Shut down the mongo service, you can now remove it from docker-compose.yaml

  • Start keycloak and configure it, similarly to how it was configured in the development setup (but choose more secure options). Update the API config file to match your keycloak configuration. Import the file export/users.json into your realm, it will re-add all the users from the old installation. You should delete the file and export/ folder afterwards.

  • Start portal.

  • Consider configuring a worker service. See deployment/README.md.
