# HedgeDoc Docker Image
!!! info "Requirements on your server"
- [Git](https://git-scm.com/)
- [Docker](https://docs.docker.com/get-docker/) 17.03.1 or higher
- [Docker Compose](https://docs.docker.com/compose/install/)
The official docker images are [available on quay.io](https://quay.io/repository/hedgedoc/hedgedoc).
We currently only support the `amd64` architecture.
The easiest way to get started with HedgeDoc and Docker is to use the following `docker-compose.yml`:
!!! warning
This is a minimal example to get started quickly and not intended for production use.
```yaml
version: '3'
services:
database:
image: postgres:13.4-alpine
environment:
- POSTGRES_USER=hedgedoc
- POSTGRES_PASSWORD=password
- POSTGRES_DB=hedgedoc
volumes:
- database:/var/lib/postgresql/data
restart: always
app:
# Make sure to use the latest release from https://hedgedoc.org/latest-release
image: quay.io/hedgedoc/hedgedoc:1.9.7
environment:
- CMD_DB_URL=postgres://hedgedoc:password@database:5432/hedgedoc
- CMD_DOMAIN=localhost
- CMD_URL_ADDPORT=true
volumes:
- uploads:/hedgedoc/public/uploads
ports:
- "3000:3000"
restart: always
depends_on:
- database
volumes:
database:
uploads:
```
After executing `docker-compose up`, HedgeDoc should be available at [http://localhost:3000](http://localhost:3000).
You can now continue to configure your container with environment variables.
Check out [the configuration docs](/configuration) for more details.
## File Permissions
By default, HedgeDoc will change the permissions of the uploads directory to
`0700` on every start of the Docker container. This is OK if you keep the files
in a named volume, but if you want to serve the files from a webserver on your
host (e.g. an Nginx reverse proxy) the webserver may not have the permission to
read the files.
To fix this, you can set the `UPLOADS_MODE` env variable to something other
than `0700`.
## Upgrading
!!! warning
Before you upgrade, **always read the release notes**.
You can find them on our [releases page](https://hedgedoc.org/releases/).
!!! info "Upgrading to 1.7"
Together with changing the name to "HedgeDoc" the default username,
password and database name have been changed in `docker-compose.yml`.
In order to migrate the existing database to the new default credentials, run
```shell
docker-compose exec database createuser --superuser -Uhackmd postgres
docker-compose exec database psql -Upostgres -c "alter role hackmd rename to hedgedoc; alter role hedgedoc with password 'password'; alter database hackmd rename to hedgedoc;"
```
before running `docker-compose up`.
You can upgrade to the latest release by stopping the containers and changing the referenced image version in `docker-compose.yml`.
Then run `docker-compose up` to start HedgeDoc again.
### Migrating from CodiMD & HackMD
If you currently use CodiMD or HackMD, you should be able to swap the docker image for ours.
See [the general migration hints](/setup/getting-started/#migrating-from-codimd-hackmd) for compatibility details.
## Backup
If you use a PostgreSQL database, you can leverage this command to create a backup:
```shell
docker-compose exec database pg_dump hedgedoc -U hedgedoc > backup.sql
```
## Restore
If you want to restore your PostgreSQL backup, run these commands before starting the application for the first time:
```shell
docker-compose up -d database
cat backup.sql | docker exec -i $(docker-compose ps -q database) psql -U hedgedoc
```
