Mark, Thanks for updating me on the ARM situation. My only comment is that it could have been easier to perhaps have an x86 server/jump host servicing an ARM pod given that testing tools do not exactly have to run on the same arch than the pod under test, but I guess decision has been made - now we need every test tool to also support ARM (that in addition to more work to support 2 arch, more test to do…).
On my side, I’ll need to check with the TRex team if they support ARM. If it does not work, every data plane test tool that uses TRex will be impacted (at least vsperf + nfvbench). It really seems to me that we could have saved all the extra hassle of ARM support with an x86 jump host (VMs is another story but we could have limited the overhead to VM artifacts only). Bin: unfortunately, I won’t be able to make it at the technical discussion meeting as it will be in the middle of my Thursday commute.

We can discuss this on Thursday. I put it on the agenda “Container Versioning / Naming Schema for x86 and ARM”.

Fair questions, but in the ARM pods there are not necessarily x86 servers to act as the host for the container. It is also my desire to support ARM for the various pods we have, and not make it difficult for them to run. We already support ARM containers for functest, yardstick, qtip and dovetail, just with a different naming scheme than other projects in docker hub. If you look at the way multiarch alpine structures their tags, yes, it is arch-version, so x86-euphrates.1.0 would be the correct way of labelling it. I realize we are getting close to Euphrates release date, so this might be postponed to F, but I would like to have a community discussion about this to see if it makes sense, or if we want to continue with creating repos to match the architecture.

How many OPNFV containers will have to support more arch than just x86? I was under the impression that most test containers could manage to run on x86 only (since we can pick the server where these test containers will run), but I am missing the arm context and why (some) test containers need to support ARM… Is that a mandate for all OPNFV test containers?

For example (from a previous email): Alpine tags as follows: multiarch/alpine:x86-latest-stable multiarch/alpine:aarch64-latest-stable Vs. in OPNFV we use the image name to specify the architecture [2], [3]: opnfv/functest:latest opnfv/functest_aarch64:latest I think the way multiarch/alpine does it is preferable so that there is only one repository name, but I think we need to discuss this across the different projects and releng to make these changes.
