can buildah build overwrite existing manifest entry?

[lazywhite]

I use following steps to build my image

# 1. create manifest
buildah manifest create demo:v1
# 2. add image to manifest
buildah build --manifest demo:v1 --platform linux/arm64 .

sometime I need to execute step2 again to rebuild image after some code changes,
but it won't overwrite the existing entry which has the same platform.
how can I do it?

@lazywhite You can do it like this, if you want to overwrite with a new image.

*) buildah build --platform linux/arm64 .
*) buildah manifest add demo:v1 containers-storage:<image-id-or-name>

Overall buildah build should also do overwrite automatically if not then its a bug, you can open an issue upstream so it can be fixed.

Thanks.
