I would prefer limiting the number of container images because we’re going to have a lot more image versions for some projects (to tackle versioned XCI/CD) So option 2 does not look great for me. I’d vote for option 1.
Have you guys looked at support for multi-arch docker images? I find it really interesting and removes the need for an arch specific tag. http://container-solutions.com/multi-arch-docker-images/ If we could implement this, that would be even better.

To align with this, the Functest Docker tags were updated from "x86_64-latest"/"aarch64-latest" to "amd64-latest"/"arm64-latest". Although the arch-naming convention is not enforced to this format (as long as the manifest points for a specific architecture to a specific tag, that tag can be named however we want), we agreed that aligning with the Docker internal format would be a good idea. My personal preference would be to duplicate the tags, and have both "x86_64-latest"/"amd64-latest", respectively "aarch64-latest"/"arm64-latest" point to the same image. Anyway, I think we should agree on a format at the OPNFV-project level, and try to use it for all our projects. So, for multiarch projects that push Docker images, we have at least 3 options: 1. "amd64"/"arm64" tags, aligning with Docker internal naming (currently used by Functest); 2. "amd64" + "x86_64" / "arm64" + "aarch64"; 3. "x86_64" / "aarch64" (currently used by Storperf); Note that if the project provides a manifest, arch-specific tags are more or less hidden from the end-user, and a simple `docker pull opnfv/functest-core:latest' (or without a tag) will fetch the image for the current system arch automatically (amd64-latest or arm64-latest for Functest). Thank you, Cédric, for handling this for Functest on such short notice!
