Afterwards, make sure to run `docker-compose up -d`.
Be sure to run `docker-compose up -d` to rebuild with the new port numbers.

## Explanation
:::warning
The server assumes to have local timezone as UTC.
All internals are handled in UTC, whenever a time is displayed to the user in UI it gets localized.
All internals are handled in UTC; whenever a time is displayed to the user in UI it gets localized.
Do not update or mount `/etc/timezone` or `/etc/localtime` in the authentik containers.
This will not give any advantages.
On the contrary, it will cause problems with OAuth and SAML authentication,
e.g. [see this GitHub issue](https://github.com/goauthentik/authentik/issues/3005).

The Docker-Compose project contains the following containers:
- server
This is the backend service, which does all the logic, runs the API and the actual SSO part. It also runs the frontend, hosts the JS/CSS files, and also serves the files you've uploaded for icons/etc.

- worker
This container executes background tasks, everything you can see on the _System Tasks_ page in the frontend.
- redis & postgresql
- redis (for cache)
Cache and database respectively.
Additionally, if you've enabled GeoIP, there is a container running that regularly updates the GeoIP database.
- postgresql (default database)
