# Alternative architectures
|
||
|
|
|
||
|
|
As stated in the [Prerequisites](prerequisites.md), currently only `x86_64` is fully supported. However, it is possible to set the target architecture, and some tools can be built on the host or other measures can be used.
|
||
|
|
|
||
|
|
To that end add the following variable to your `vars.yaml` file:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
matrix_architecture: <your-matrix-server-architecture>
|
||
|
|
```
|
||
|
|
|
||
|
|
Currently supported architectures are the following:
|
||
|
|
- `amd64` (the default)
|
||
|
|
- `arm64`
|
||
|
|
- `arm32`
|
||
|
|
|
||
|
|
so for the Raspberry Pi, the following should be in your `vars.yaml` file:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
matrix_architecture: "arm32"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Implementation details
|
||
|
|
|
||
|
|
For `amd64`, prebuilt container images (see the [container images we use](container-images.md)) are used everywhere, because all images are available for this architecture.
|
||
|
|
|
||
|
|
For other architectures, components which have a prebuilt image make use of it. If the component is not available for the specific architecture, [self-building](self-building.md) will be used. Not all components support self-building though, so your mileage may vary.
