[Heimdall](https://heimdall.site) is a way to organise all those links to your most used web sites and web applications in a simple way.
Simplicity is the key to Heimdall.
Why not use it as your browser start page? It even has the ability to include a search bar using either Google, Bing or DuckDuckGo.

## Supported Architectures

Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).

Simply pulling `ghcr.io/linuxserver/heimdall` 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 | Tag |
| :----: | --- |
| x86-64 | amd64-latest |
| arm64 | arm64v8-latest |
| armhf | arm32v7-latest |

## Version Tags

This image provides various versions that are available via tags. `latest` tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.

| Tag | Description |
| :----: | --- |
| latest | Stable Heimdall releases. |
| development | Latest commit from the github master branch. |

## Usage

Here are some example snippets to help you get started creating a container from this image.

### docker-compose ([recommended](https://docs.linuxserver.io/general/docker-compose))

Compatible with docker-compose v2 schemas.

```yaml
---
version: "2.1"
services:
  heimdall:
    image: ghcr.io/linuxserver/heimdall
    container_name: heimdall
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - </path/to/appdata/config>:/config
    ports:
      - 80:80
      - 443:443
    restart: unless-stopped
```

### docker cli

```
docker run -d \
  --name=heimdall \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 80:80 \
  -p 443:443 \
  -v </path/to/appdata/config>:/config \
  --restart unless-stopped \
  ghcr.io/linuxserver/heimdall
```


## 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 |
| :----: | --- |
| `80` | http gui |
| `443` | https gui |


### Environment Variables (`-e`)

| Env | Function |
| :----: | --- |
| `PUID=1000` | for UserID - see below for explanation |
| `PGID=1000` | for GroupID - see below for explanation |
| `TZ=Europe/London` | Specify a timezone to use EG Europe/London |

### Volume Mappings (`-v`)

| Volume | Function |
| :----: | --- |
| `/config` | Contains all relevant configuration files. |



## 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](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.

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)
```

## Application Setup

Access the web gui at http://SERVERIP:PORT


### Adding password protection

This image now supports password protection through htpasswd. Run the following command on your host to generate the htpasswd file `docker exec -it heimdall htpasswd -c /config/nginx/.htpasswd <username>`. Replace <username> with a username of your choice and you will be asked to enter a password. New installs will automatically pick it up and implement password protected access. Existing users updating their image can delete their site config at `/config/nginx/site-confs/default` and restart the container after updating the image. A new site config with htpasswd support will be created in its place.

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.
