[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 `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

```
docker create \
  --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 \
  linuxserver/heimdall
```


### docker-compose

Compatible with docker-compose v2 schemas.

```yaml
---
version: "2"
services:
  heimdall:
    image: 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
```

## 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. |



## 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.



## Support Info

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