| inventree-worker | django-q background worker |
| inventree-proxy | Caddy file server and reverse proxy |

#### PostgreSQL Database
A PostgreSQL database container which requires a username:password combination (which can be changed). This uses the official [PostgreSQL image](https://hub.docker.com/_/postgres).
#### Web Server
Runs an InvenTree web server instance, powered by a Gunicorn web server.
#### Background Worker
Runs the InvenTree background worker process. This spins up a second instance of the *inventree* container, with a different entrypoint command.
#### Proxy Server
Caddy working as a reverse proxy, separating requests for static and media files, and directing everything else to Gunicorn.
This container uses the official [caddy image](https://hub.docker.com/_/caddy).
!!! info "Nginx Proxy"
An alternative is to run nginx as the reverse proxy. A sample configuration file is provided in the `./contrib/container/` source directory.
#### Redis Cache
Redis is used as cache storage for the InvenTree server. This provides a more performant caching system which can useful in larger installations.
This container uses the official [redis image](https://hub.docker.com/_/redis).
!!! info "Redis on Docker"
Docker adds an additional network layer - that might lead to lower performance than bare metal.
To optimize and configure your redis deployment follow the [official docker guide](https://redis.io/docs/getting-started/install-stack/docker/#configuration).
!!! tip "Enable Cache"
While a redis container is provided in the default configuration, by default it is not enabled in the Inventree server. You can enable redis cache support by following the [caching configuration guide](./config.md#caching)
