NOTE: If you intend to run Vikunja with mysql and/or to use non-latin characters
}}">make sure your db is utf-8 compatible.
All examples on this page already reflect this and do not require additional work.

## Redis
While Vikunja has support to use redis as a caching backend, you'll probably not need it unless you're using Vikunja
with more than a handful of users.
To use redis, you'll need to add this to the config examples below:
{{< highlight yaml >}}
version: '3'
services:
api:
image: vikunja/api
environment:
VIKUNJA_REDIS_ENABLED: 1
VIKUNJA_REDIS_HOST: 'redis:6379'
VIKUNJA_CACHE_ENABLED: 1
VIKUNJA_CACHE_TYPE: redis
volumes:
- ./files:/app/vikunja/files
redis:
image: redis
{{< /highlight >}}
## PostgreSQL
Vikunja supports postgres, mysql and sqlite as a database backend. The examples on this page use mysql with a mariadb container.
To use postgres as a database backend, change the `db` section of the examples to this:
{{< highlight yaml >}}
db:
image: postgres:13
environment:
POSTGRES_PASSWORD: secret
POSTGRES_USER: vikunja
volumes:
- ./db:/var/lib/postgresql/data
restart: unless-stopped
{{< /highlight >}}
You'll also need to change the `VIKUNJA_DATABASE_TYPE` to `postgres` on the api container declaration.
