How to build

1. Install docker
   • Each operating system has a different way, but it's recommended to install the latest version, check the docker installation instructions.
2. Install docker buildx
3. Enable docker experimental features
   • You can check that with docker version
   • For more information check docker experimental README
4. Create a node to for armv6 with the correct configuration
   • docker buildx create --use --platform=linux/arm/v6 --buildkitd-flags '--allow-insecure-entitlement network.host --allow-insecure-entitlement security.insecure' --name arm-builder
5. Pull latest changes to avoid building everything from scratch
   • docker pull --platform linux/arm/v6 bluerobotics/companion-core:master
6. Build it
   • Be aware that crosscompiling the core image will take some time in a good computer.
   • docker buildx build --platform linux/arm/v6 . -t user/companion-core --push --output type=registry --progress=plain
