HedgeDoc Docker Image

Requirements on your server

The official docker images are available on quay.io. 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.

version: '3'
services:
  database:
    image: postgres:9.6-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:1.8.2
    environment:
      - CMD_DB_URL=postgres://hedgedoc:[email protected]: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://127.0.0.1:3000.
You can now continue to configure your container with environment variables. Check out the configuration docs for more details.

Upgrading

Warning

Before you upgrade, always read the release notes.
You can find them on our releases page.

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 

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 for compatibility details.

Backup

If you use a PostgreSQL database, you can leverage this command to create a backup: 

 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:

docker-compose up -d database
cat backup.sql | docker exec -i $(docker-compose ps -q database) psql -U hedgedoc
