[Double Commander](https://doublecmd.sourceforge.io/) is a free cross platform open source file manager with two panels side by side. It is inspired by Total Commander and features some new ideas.

## 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 `lscr.io/linuxserver/doublecommander` 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 | latest |
| arm64 | arm64v8-latest |
| armhf | arm32v7-latest |

## Application Setup

The application can be accessed at:

* http://yourhost:3000/

By default the user/pass is abc/abc, if you change your password or want to login manually to the GUI session for any reason use the following link:

* http://yourhost:3000/?login=true

## Usage

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

### docker-compose (recommended, [click here for more info](https://docs.linuxserver.io/general/docker-compose))

```yaml
---
version: "2.1"
services:
  doublecommander:
    image: lscr.io/linuxserver/doublecommander
    container_name: doublecommander
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - /path/to/config:/config
      - /path/to/data:/data
    ports:
      - 3000:3000
    restart: unless-stopped
```

### docker cli ([click here for more info](https://docs.docker.com/engine/reference/commandline/cli/))

```bash
docker run -d \
  --name=doublecommander \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 3000:3000 \
  -v /path/to/config:/config \
  -v /path/to/data:/data \
  --restart unless-stopped \
  lscr.io/linuxserver/doublecommander
```

## 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` | Double Commander desktop 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` | Users home directory in the container, stores program settings. |
| `/data` | Host data directories, mount as many as needed. |

#### 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:

```bash
-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:

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

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.

## Support Info
