[HedgeDoc](https://hedgedoc.org/) 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.
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://distribution.github.io/distribution/spec/manifest-v2-2/#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
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.
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)
To run behind a reverse proxy we have a [preconfigured config](https://github.com/linuxserver/reverse-proxy-confs/blob/master/hedgedoc.subdomain.conf.sample) using docker networking included in our [SWAG](https://github.com/linuxserver/docker-swag) image and you can read how to use this in the [Reverse Proxy Confs repository](https://github.com/linuxserver/reverse-proxy-confs/#how-to-use-these-reverse-proxy-configs)
Containers 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.
| `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_DB_DIALECT=` | This variable allows selecting a database engine (if DB_HOST not set up). Available options are: `mariadb`, `mysql`, `postgres`, `sqlite`. |
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](https://en.wikipedia.org/wiki/Umask) 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.

We publish various [Docker Mods](https://github.com/linuxserver/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.
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
### Via Docker Compose
* Update images:
* All images:
```bash
docker-compose pull
```
* Single image:
```bash
docker-compose pull hedgedoc
```
* Update containers:
* All containers:
```bash
docker-compose up -d
```
* Single container:
```bash
docker-compose up -d hedgedoc
```
* You can also remove the old dangling images:
```bash
docker image prune
```
### Via Docker Run
* Update the image:
```bash
docker pull lscr.io/linuxserver/hedgedoc:latest
```
* Stop the running container:
```bash
docker stop hedgedoc
```
* Delete the container:
```bash
docker rm hedgedoc
```
* Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
