linuxserver/hedgedoc

HedgeDoc gives you access to all your files wherever you are.

HedgeDoc is a real-time, multi-platform collaborative markdown note editor. This means that you can write notes with other people on your desktop, tablet or even on the phone. You can sign-in via multiple auth providers like Facebook, Twitter, GitHub and many more on the homepage.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/hedgedoc:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	✅	arm32v7-<version tag>

Application Setup

HedgeDoc web interface can be accessed http://${IP}:3000/, if you want to use a custom domain or anything besides port 3000 you will need to leverage their env settings for callbacks: (specifically for CMD_DOMAIN, CMD_PORT and CMD_URL_ADDPORT)

Full list of HedgeDoc options

For convience we provide a working example using Mysql as a backend in this document, if you do not wish to use our custom environment values or a Mysql database backend feel free to leverage any of the settings laid out in the link above.

To run behind a reverse proxy we have a preconfigured config using docker networking included in our SWAG image and you can read how to use this in the Reverse Proxy Confs repository

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Parameter	Function
3000	Web gui port (internal port also needs to be changed if accessing at port other than 80, 443 and 3000).

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=Etc/UTC	specify a timezone to use, see this list.
DB_HOST=<hostname or ip>	Host address of mysql database
DB_PORT=3306	Port to access mysql database default is 3306
DB_USER=hedgedoc	Database user
DB_PASS=<secret password>	Database password
DB_NAME=hedgedoc	Database name
CMD_DOMAIN=localhost	The address the gui will be accessed at (ie. 192.168.1.1 or hedgedoc.domain.com).
CMD_URL_ADDPORT=false	Set to true if using a port other than 80 or 443.
CMD_PROTOCOL_USESSL=false	Set to true if accessing over https via reverse proxy.
CMD_PORT=3000	If you wish to access hedgedoc at a port different than 80, 443 or 3000, you need to set this to that port (ie. CMD_PORT=5000) and change the port mapping accordingly (5000:5000).
CMD_ALLOW_ORIGIN=['localhost']	Comma-separated list of allowed hostnames

Volume Mappings (-v)

Volume	Function
/config	HedgeDoc config and configurable files

Miscellaneous Options

Parameter	Function

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

• Shell access whilst the container is running:
  • docker exec -it hedgedoc /bin/bash
• To monitor the logs of the container in realtime:
  • docker logs -f hedgedoc
• Container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' hedgedoc
• Image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/hedgedoc:latest
