# Docker Guide
::: info Non-Docker Guides
We only publish and maintain self-hosting guides using Docker as this removes many environment-specific configuration
problems. If you can't or don't want to use Docker, we also publish an
[npm package](https://www.npmjs.com/package/directus) without guides.
:::
Directus is published to [Docker Hub](https://hub.docker.com/r/directus/directus) under `directus/directus`. If you're
just getting started, check out our [Self-Hosting Quickstart](/self-hosted/quickstart.html).
## Installing Specific Versions
To stick to a more specific version of Directus you can use one of the following tags:
- Full version, e.g. `{{ packages.directus.version.full }}`
- Minor releases, e.g. `{{ packages.directus.version.minor }}`
- Major releases, e.g. `{{ packages.directus.version.major }}`
It is recommended to explicitly specify a Directus version in your `docker-compose.yml` file. Include the version number
in your `services.directus.image` value:
```yaml-vue
services:
directus:
image: directus/directus:latest // [!code --]
image: directus/directus:{{ packages.directus.version.full }} // [!code ++]
```
## Configure Admin User
The `ADMIN_EMAIL` and `ADMIN_PASSWORD` variables, while shown in the quickstart, are optional. If omitted, the published
Docker image will automatically populate the database and create an admin user, and these will only be shown in the
Docker bootstrap logs when starting Directus for the first time. To configure the email/password for this first user,
include the following environment variables:
```bash
ADMIN_EMAIL="admin@example.com"
ADMIN_PASSWORD="d1r3ctu5"
```
Once you've started Directus for the first time, assuming your database is persisted, you can remove these values from
your compose file.
## Persistence
Containers are ephemeral, and this means that whenever you stop a container, all the data associated with it is going to
be removed [unless you persist them](https://docs.docker.com/storage) when creating your container.
Directus image by default will use the following locations for data persistence (note that these can be changed through
environment variables):
- `/directus/database` (only when using SQLite and not configured to a different folder)
- `/directus/uploads` for uploads
- `/directus/extensions` for loading extensions
- `/directus/templates` for overriding and extending email templates
The `services.directus.volumes` section in your docker-compose.yml is optional. To persist data to your local machine,
include a list of persisted directories:
```yaml
services:
directus:
volumes:
- ./database:/directus/database
- ./uploads:/directus/uploads
- ./extensions:/directus/extensions
- ./templates:/directus/templates
```
## Example Docker Compose
While the [Self-Hosting Quickstart](/self-hosted/quickstart.html) aims to show you the minimum-viable
`docker-compose.yml` file, here is a more complete one that spins up a Postgres database, Redis cache, and Directus
project:
```yaml-vue
version: "3"
services:
database:
image: postgis/postgis:13-master
# Required when running on platform other than amd64, like Apple M1/M2:
# platform: linux/amd64
volumes:
- ./data/database:/var/lib/postgresql/data
environment:
POSTGRES_USER: "directus"
POSTGRES_PASSWORD: "directus"
POSTGRES_DB: "directus"
cache:
image: redis:6
directus:
image: directus/directus:{{ packages.directus.version.full }}
ports:
- 8055:8055
volumes:
- ./uploads:/directus/uploads
- ./extensions:/directus/extensions
depends_on:
- cache
- database
environment:
SECRET: "replace-with-secure-random-value"
DB_CLIENT: "pg"
DB_HOST: "database"
DB_PORT: "5432"
DB_DATABASE: "directus"
DB_USER: "directus"
DB_PASSWORD: "directus"
CACHE_ENABLED: "true"
CACHE_AUTO_PURGE: "true"
CACHE_STORE: "redis"
REDIS: "redis://cache:6379"
ADMIN_EMAIL: "admin@example.com"
ADMIN_PASSWORD: "d1r3ctu5"
# Make sure to set this in production
# (see https://docs.directus.io/self-hosted/config-options#general)
# PUBLIC_URL: "https://directus.example.com"
# Environment variables can also be defined in a file (for example `.env`):
# env_file:
# - .env
```
### Updating With Docker Compose
If you are not using the `latest` tag for the Directus image you need to adjust your `docker-compose.yml` file to
increment the tag version number, e.g.:
```diff-vue
- image: directus/directus:{{ packages.directus.version.major }}.0.0
+ image: directus/directus:{{ packages.directus.version.full }}
```
Then run the following from your docker-compose root:
```bash
docker compose up
```
The specified image will be pulled and the containers recreated. Migrations will happen automatically so once the
containers have started you will be on the latest version (or the version you specified).
## Supported Databases
The Directus Docker Image contains all optional dependencies supported in the API. This means the Docker image can be
used with most of the supported databases and storage adapters without having to create a custom image.
Directus supports the LTS versions of PostgreSQL, MySQL, SQLite, MS SQL Server, MariaDB, CockroachDB, and OracleDB.
Please see https://endoflife.date/ to make sure your database version is still supported.
## Requirements
It can be easy to under-provision resources to run a self-hosted instance of Directus. For Directus' container
resources, the required minimum system requirements are 1x 0.25 vCPU / 512 MB, although the recommended minimum is 2x 1
vCPU / 2GB.
