The following sections describe the commands needed to create a multi-cpu architecture container image. Let's call the image onap/py-app.
...
| Code Block |
|---|
docker push onap/py-app-arm64arm64v8:latest |
Build Intel image (B)
...
| Code Block |
|---|
docker manifest create onap/py-app \
onap/py-app-arm64arm64v8 \
onap/py-app-amd64 |
Verify that the manifest describes a multi-cpu architecture container image.

Intermediate Image Naming Convention
As described above, multiplatform-cpu architecture agnostic support requires platform specific images that are put together to expose a multi-platform image. Architectures Platform architectures include, among others, arm,intel, mips, ppc64le, and s390x
...
Note: This table does not contain a exhaustive list of options and must only be used as an image naming guide. Because ONAP is vendor-agnostic, it the list is not intended as a statement of what architectures or OSs ONAP must support.
