## <a id="build-docker"></a>Build in Docker

To build for Linux, you can alternatively build VSCodium in docker

### <a id="build-docker-x64"></a>X64

Firstly, create the container with:
```
docker run -ti --volume=<local vscodium source>:/root/vscodium --name=vscodium-build-agent vscodium/vscodium-linux-build-agent:bionic-x64 bash
```
like
```
docker run -ti --volume=$(pwd):/root/vscodium --name=vscodium-build-agent vscodium/vscodium-linux-build-agent:bionic-x64 bash
```

When inside the container, you can use the following commands to build:
```
cd /root/vscodium

./build/build.sh
```

### <a id="build-docker-arm32"></a>ARM 32bits

Firstly, create the container with:
```
docker run -ti --volume=<local vscodium source>:/root/vscodium --name=vscodium-build-agent vscodium/vscodium-linux-build-agent:bionic-armhf bash
```
like
```
docker run -ti --volume=$(pwd):/root/vscodium --name=vscodium-build-agent vscodium/vscodium-linux-build-agent:bionic-armhf bash
```

```
curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt-get install -y nodejs desktop-file-utils

cd /root/vscodium

./build/build.sh
