The [LinuxServer.io](https://linuxserver.io) team brings you another container release featuring:
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://distribution.github.io/distribution/spec/manifest-v2-2/#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Simply pulling `lscr.io/linuxserver/audacity:latest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
This image uses a self-signed certificate by default. This naturally means the scheme is `https`.
If you are using a reverse proxy which validates certificates, you need to [disable this check for the container](https://docs.linuxserver.io/faq#strict-proxy).
**Modern GUI desktop apps may have compatibility issues with the latest Docker syscall restrictions. You can use Docker with the `--security-opt seccomp=unconfined` setting to allow these syscalls on hosts with older Kernels or libseccomp versions.**
**HTTPS is required for full functionality.** Modern browser features such as WebCodecs, used for video and audio, will not function over an insecure HTTP connection.
By default, this container has no authentication. The optional `CUSTOM_USER` and `PASSWORD` environment variables enable basic HTTP auth, which is suitable only for securing the container on a trusted local network. For internet exposure, we strongly recommend placing the container behind a reverse proxy, such as [SWAG](https://github.com/linuxserver/docker-swag), with a robust authentication mechanism.
The web interface includes a terminal with passwordless `sudo` access. Any user with access to the GUI can gain root control within the container, install arbitrary software, and probe your local network.
While not generally recommended, certain legacy environments specifically those with older hardware or outdated Linux distributions may require the deactivation of the standard seccomp profile to get containerized desktop software to run. This can be achieved by utilizing the `--security-opt seccomp=unconfined` parameter. It is critical to use this option only when absolutely necessary as it disables a key security layer of Docker, elevating the potential for container escape vulnerabilities.
This container is based on [Docker Baseimage Selkies](https://github.com/linuxserver/docker-baseimage-selkies), which provides the following environment variables and run configurations to customize its functionality.
| `--privileged` | Starts a Docker-in-Docker (DinD) environment. For better performance, mount the Docker data directory from the host, e.g., `-v /path/to/docker-data:/var/lib/docker`. |
| `-v /var/run/docker.sock:/var/run/docker.sock` | Mounts the host's Docker socket to manage host containers from within this container. |
| `--device /dev/dri:/dev/dri` | Mount a GPU into the container, this can be used in conjunction with the `DRINODE` environment variable to leverage a host video card for GPU accelerated applications. Only **Open Source** drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau) |
Nvidia GPU support is available by leveraging Zink for OpenGL. When a compatible Nvidia GPU is passed through, it will also be **automatically utilized for hardware-accelerated video stream encoding** (using the `x264enc` full-frame profile), significantly reducing CPU load.
Enable Nvidia support with the following runtime flags:
Natively installed packages (e.g., via `apt-get install`) will not persist if the container is recreated. To retain applications and their settings across container updates, we recommend using [proot-apps](https://github.com/linuxserver/proot-apps). These are portable applications installed to the user's persistent `$HOME` directory.
You can install packages from the system's native repository using the [universal-package-install](https://github.com/linuxserver/docker-mods/tree/universal-package-install) mod. This method will increase the container's start time and is not persistent. Add the following to your `compose.yaml`:
These variables can be used to lock down the desktop environment for single-application use cases or to restrict user capabilities.
##### Meta Variables
These variables act as presets, enabling multiple hardening options at once. Individual options can still be set to override the preset.
| Variable | Description |
| :----: | --- |
| **`HARDEN_DESKTOP`** | Enables `DISABLE_OPEN_TOOLS`, `DISABLE_SUDO`, and `DISABLE_TERMINALS`. Also sets related Selkies UI settings (`SELKIES_FILE_TRANSFERS`, `SELKIES_COMMAND_ENABLED`, `SELKIES_UI_SIDEBAR_SHOW_FILES`, `SELKIES_UI_SIDEBAR_SHOW_APPS`) if they are not explicitly set by the user. |
| **`HARDEN_OPENBOX`** | Enables `DISABLE_CLOSE_BUTTON`, `DISABLE_MOUSE_BUTTONS`, and `HARDEN_KEYBINDS`. It also flags `RESTART_APP` if not set by the user, ensuring the primary application is automatically restarted if closed. |
##### Individual Hardening Variables
| Variable | Description |
| :--- | --- |
| **`DISABLE_OPEN_TOOLS`** | If true, disables `xdg-open` and `exo-open` binaries by removing their execute permissions. |
| **`DISABLE_SUDO`** | If true, disables the `sudo` command by removing its execute permissions and invalidating the passwordless sudo configuration. |
| **`DISABLE_TERMINALS`** | If true, disables common terminal emulators by removing their execute permissions and hiding them from the Openbox right-click menu. |
| **`DISABLE_CLOSE_BUTTON`** | If true, removes the close button from window title bars in the Openbox window manager. |
| **`DISABLE_MOUSE_BUTTONS`** | If true, disables the right-click and middle-click context menus and actions within the Openbox window manager. |
| **`HARDEN_KEYBINDS`** | If true, disables default Openbox keybinds that can bypass other hardening options (e.g., `Alt+F4` to close windows, `Alt+Escape` to show the root menu). |
| **`RESTART_APP`** | If true, enables a watchdog service that automatically restarts the main application if it is closed. The user's autostart script is made read-only and root owned to prevent tampering. |
#### Selkies application settings
Using environment variables every facet of the application can be configured.
##### Booleans and Locking
Boolean settings accept `true` or `false`. You can also prevent the user from changing a boolean setting in the UI by appending `|locked`. The UI toggle for this setting will be hidden.
***Example**: To force CPU encoding on and prevent the user from disabling it:
```bash
-e SELKIES_USE_CPU="true|locked"
```
##### Enums and Lists
These settings accept a comma-separated list of values. Their behavior depends on the number of items provided:
***Multiple Values**: The first item in the list becomes the default selection, and all items in the list become the available options in the UI dropdown.
***Single Value**: The provided value becomes the default, and the UI dropdown is hidden because the choice is locked.
***Example**: Force the encoder to be `jpeg` with no other options available to the user:
```bash
-e SELKIES_ENCODER="jpeg"
```
##### Ranges
Range settings define a minimum and maximum for a value (e.g., framerate).
***To set a range**: Use a hyphen-separated `min-max` format. The UI will show a slider.
***To set a fixed value**: Provide a single number. This will lock the value and hide the UI slider.
***Example**: Lock the framerate to exactly 60 FPS.
```bash
-e SELKIES_FRAMERATE="60"
```
##### Manual Resolution Mode
The server can be forced to use a single, fixed resolution for all connecting clients. This mode is automatically activated if `SELKIES_MANUAL_WIDTH`, `SELKIES_MANUAL_HEIGHT`, or `SELKIES_IS_MANUAL_RESOLUTION_MODE` is set.
* If `SELKIES_MANUAL_WIDTH` and/or `SELKIES_MANUAL_HEIGHT` are set, the resolution is locked to those values.
* If `SELKIES_IS_MANUAL_RESOLUTION_MODE` is set to `true` without specifying width or height, the resolution defaults to **1024x768**.
* When this mode is active, the client UI for changing resolution is disabled.

Containers 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.
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.
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`.

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.
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
* Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
>We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
* **14.09.21:** - Use the official appimage, switch to single arch (x86_64). Armhf and aarch64 users can remain on version 3.0.2 but there won't be further updates.
