# Upgrading
|
|
|
|
This document describes the general steps to upgrade between major changes.
|
|
Simple migrations, e.g. for adding schema changes, are not documented
|
|
explicitly. Once we implement them, their usage will be described in the
|
|
[README](./README.md).
|
|
|
|
|
|
## 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
|
|
* Update docker-compose.yaml from the example. Leave the MongoDB service in
|
|
place for now, but update all other service descriptions. You can remove
|
|
`redis` already.
|
|
* Start up the `mongo` and `postgres` services
|
|
* Build the new images (e.g. with `docker-compose build`)
|
|
* 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.
|
|
* Run the database reset script: `docker-compose run --rm api python tools/reset_database.py`
|
|
* Run the database migration script: `docker-compose run --rm api python
|
|
tools/import_from_mongodb.py mongodb://mongo/obs`. You might need to adjust
|
|
the URL.
|
|
* 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.
|
|
* Start `api`, `worker` and `frontend`
