[Thelounge](https://thelounge.github.io/) (a fork of shoutIRC) is a web IRC client that you host on your own server.

## 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/thelounge` 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 |


## 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:
  thelounge:
    image: ghcr.io/linuxserver/thelounge
    container_name: thelounge
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - </path/to/appdata/config>:/config
    ports:
      - 9000:9000
    restart: unless-stopped
```

### docker cli

```
docker run -d \
  --name=thelounge \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 9000:9000 \
  -v </path/to/appdata/config>:/config \
  --restart unless-stopped \
  ghcr.io/linuxserver/thelounge
```


## 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 |
| :----: | --- |
| `9000` | Application WebUI |


### 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` | 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

 * When the application first runs, it will populate its /config
* Stop the container
* Now from the host, edit `/config/config.js`, wherever you've mapped it
* In most cases you want the value `public: false` to allow named users only
* Setting the two prefetch values to true improves usability, but uses more storage
* Once you have the configuration you want, save it and start the container again
* For each user, run the command
* `docker exec -it thelounge s6-setuidgid abc thelounge add <user>`
* You will be prompted to enter a password that will not be echoed.
* Saving logs to disk is the default, this consumes more space but allows scrollback.
* To log in to the application, browse to `http://<hostip>:9000`
* You should now be prompted for a username and password on the webinterface.
* Once logged in, you can add an IRC network. Some defaults are preset for Freenode.

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.
