Buildx, BuildKit, drivers, and Build Cloud
Take a quick look at the Docker build system, including Buildx, BuildKit, multi-architecture builds, and using cloud-based services for efficient and faster image creation.
In this section we take a quick look at the major components that power builds. Docker’s build system has a client and server architecture:
- Client: Buildx
- Server: BuildKit
The Buildx build client
Buildx is Docker’s latest and greatest build client. It’s implemented as a CLI plugin and supports all the latest features of
We can configure Buildx to talk to multiple BuildKit instances, and we call each instance of BuildKit a builder. Builders can be on your local machine, in your cloud or datacenter, or Docker’s Build Cloud.
If we point buildx at a local builder, image builds will be done on our local machine. If we point it at a remote builder, such as Docker Build Cloud, builds will be done on remote infrastructure. The figure below shows a Docker environment configured to talk to a local and a remote builder.
