[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 `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 |
2020-06-29 07:29:55 +00:00
| :---: | :--- |
2020-03-25 20:55:28 +00:00
| x86-64 | 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
2020-06-29 07:29:55 +00:00
```text
2020-03-25 20:55:28 +00:00
docker create \
--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 \
linuxserver/doublecommander
```
### docker-compose
Compatible with docker-compose v2 schemas.
```yaml
---
2020-04-12 22:58:21 +00:00
version: "2.1"
2020-03-25 20:55:28 +00:00
services:
doublecommander:
image: 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
```
## Parameters
2020-06-29 07:29:55 +00:00
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.

| `/config` | Users home directory in the container, stores program settings. |
| `/data` | Host data directories, mount as many as needed. |
2020-06-29 07:29:55 +00:00
## Environment variables from files \(Docker secrets\)
2020-05-31 22:57:55 +00:00
You can set any environment variable from a file by using a special prepend `FILE__` .
As an example:
2020-06-29 07:29:55 +00:00
```text
2020-05-31 22:57:55 +00:00
-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
2020-06-29 07:29:55 +00:00
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
2020-06-29 07:29:55 +00:00
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` .
2020-03-25 20:55:28 +00:00
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:
2020-06-29 07:29:55 +00:00
```text
2020-03-25 20:55:28 +00:00
$ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
```
## Application Setup
The application can be accessed at:
2020-06-29 07:29:55 +00:00
* [http://yourhost:3000/ ](http://yourhost:3000/ )
2020-03-25 20:55:28 +00:00
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:
2020-06-29 07:29:55 +00:00
* [http://yourhost:3000/?login=true ](http://yourhost:3000/?login=true )
