When you build a container image, it’s typically only built for one platform (
linux) and one architecture (
As the Internet of Things continues to grow, the demand for more
arm images increased as well.
Traditionally, in order to produce an
arm image, you need an
arm device to do the build on.
As a result, most projects wind up missing
BuildKit provides emulation capabilities that support multi-architecture builds.
With BuildKit, you build container images across multiple architectures concurrently.
This core utility backs
