  • 1.  Apstra-OpenSTack integration

    Posted 03-07-2023 16:27

    Dear Juniper Experts,

    Pradeep H Krishnamurthy explained in his great post how to integrate CN2 with Apstra to manage fabrics for Kubernetes environments. My question is, we know that Apstra doesn't integrate with OpenStack natively, can we use CN2-Apstra Plug-in to integrate Apstra with OpenStack, so we can provision the fabric automatically according to OpenStack Neutron needs?

    Regards,

    Yaser

    Hi Yaser,
    Thank you for your query.
    We have a strategy to decouple the software and hardware. It's unwise for users to tie the fate of their OpenStack choice to the underlay fabric overall.
    Having said that, when CN2 supports the new versions of OpenStack, we will evaluate making it work for SRIOV workloads in that environment with the same CN2 and Apstra integration. 
    SRIOV attachment isn't as standard in OpenStack, so the question would be how to automate the ToR port binding into a fabric VN. But at minimum the process of extending VNs from CN2 to Apstra should still work the same as it does today.

    Dear Vivek,

    Thank you for your reply. I am coming from SP networking world, so please excuse my limited knowledge of this topic. I didn't fully understand your answer, so please let me list my questions about it in bullet points:

    1- To my understanding, the current CN2 version (Release 22.4) doesn't support the latest version of OpenStack (although it is clearly mentioned that OpenStack is supported in CN2 datasheet), if this is the case, what is the latest supported OpenStack version?

    2- To my understanding, CN2 can function as CNI in Kubernetes environments, regardless of SRIOV, but it seems that SRIOV is a condition for CN2 to work with OpenStack, kindly elaborate.

    3- Is there any way to say that  Apstra can integrate with OpenStack? if not, will it be in the future?

    Thanks in advance.

    Hi Yaser,

    • CN2 is just adding supporting for OSP this year. We expect it to be ready for production in Q4.

    2- To my understanding, CN2 can function as CNI in Kubernetes environments, regardless of SRIOV, but it seems that SRIOV is a condition for CN2 to work with OpenStack, kindly elaborate.

    •  That is correct , CN2 is native to kubernetes enviroments. We will have more clarity on the need for SRIOV in OSP when we have completed the onboarding in Q4.

    3- Is there any way to say that  Apstra can integrate with OpenStack? if not, will it be in the future?

    • We will evaluate all the Apstra integration related features next year (2024) when it comes to OpenStack.
