# Build container

**Docker containers**
- Ubuntu
  - focal     (Ubuntu 20.04)
  - jammy     (Ubuntu 22.04)
  - noble     (Ubuntu 24.04)
- Debian
  - bookworm  (Debian 12)

**Build docker image**

Use the following command to create a docker image and tag it with `libreelec`.

```
docker build --pull -t libreelec tools/docker/jammy
```

See https://docs.docker.com/engine/reference/commandline/build/ for details on `docker build` usage.

**Build LibreELEC image inside a container**

Change to your LibreELEC.tv development directory that you checked out with <br>
 `git clone https://github.com/`**myname**`/LibreELEC.tv.git`

 ```
 cd LibreELEC.tv
 ```

Then use the following command to build LibreELEC images inside a new container based on the docker image tagged with `libreelec`. (The `pwd` uses the current directory - which must have the LibeELEC `Makefile` in it.)

```
docker run --rm --log-driver none -v `pwd`:/build -w /build -it libreelec make image
```

Use `--env`, `-e` or `--env-file` to pass environment variables used by the LibreELEC buildsystem.

```
docker run --rm --log-driver none -v `pwd`:/build -w /build -it -e PROJECT=RPi -e DEVICE=RPi4 -e ARCH=arm libreelec make image
```

See https://docs.docker.com/engine/reference/commandline/run/ for details on `docker run` usage.

Note: `dockerd` is set to send all its logs to journald using the setting `--log-driver=journald` (so if you don't set the `--log-driver none` for your `docker run` these logs will be sent through to your log.
