What is build-kit

Refer to build ARM based Docker Images Simply put, it is an extension docker build An experimental function of

Take bind as an example to build it

The docker-bind project is an open source custom DNS deployment service, but does not provide a service based on linux/aarch64 The available image of the schema, so you need to use it yourself buildx Command to perform a build operation

In the raspberry pie system, execute the uname -a To view your target schema

linux/aarch64 linux/amd64 linux/arm64 linux/arm/v7

....

#  Execute the following command in the raspberry pie system 
git clone https://github.com/sameersbn/docker-bind.git
cd docker-bind
#  Modify Dockerfile Content, pay attention! ! This setting is the same as docker-bind Relating to, relating to build-kit It has nothing to do with the use of, only for demonstration
