This element enables execution for different architectures
|
|
|
|
When building an image for an architecture that the host machine
|
|
can not execute, we need to chroot into the image to execute code,
|
|
and if the host architecture does not match, we need to emulate
|
|
the instructions.
|
|
|
|
This element does the following:
|
|
|
|
* copies the binary file into chroot /usr/bin environment.
|
|
Binary file is chosen based on host architecture and
|
|
image architecture the user is trying to build.
|
|
|
|
If an image we are building for an architecture is not the host
|
|
architecture, install tools provided by qemu-user-static
|
|
(which needs to be installed) to allow us to run commands
|
|
inside the building image.
|
|
|
|
This is tested on amd64/i386 architecture to build armhf and arm64
|
|
ubuntu cloud images.
