Gitlab GitOps for Telco overview

Due to last minute critical constraint, the first presentation has been canceled. It could be replanned next time.

Tool to audit workload’s platform requirements

Marcin Franczyk (MF) presented Node Feature Discovery (NFD), a Kubernetes add-on to check the image compatibility.

It also shared Image Compatibility Spec that you can add to your OCI artifacts and that can be used to check if the node supports your requirements (cpu, memory, kernel module, ..). The spec is included in the OCI image and compatible with any orchestrator using OCI artifacts. Discussions are in progress to define the spec and ease the adoption by the industry. Vendors should include this compatibility spec. One of the difficulty is to consider the min hardware requirements and exclude performance topics.

A demo based on a 6Wind VSR has been done (See replay). Through NFD, we got a clear indication that the Kubernetes node is not compatible with what has been declared by the CNF vendor. The capability of the cluster are detected through jobs executed on the different nodes.

The re is currently no scheduler, but possible contributors already expressed their interest to work on such scheduler that would include this compatibility check.

Quick overview of Telco GitOps initiatives

Sharing of views on GitOps approach by L.Velarde (Telefonica) and R.Gasparetto Stori(Vodafone). LV indicated that GitOps became a trend. He highlighted the advantages of having a single source of truth, the ability to manage multi-site and multi-vendor environments with a single DevOps methodology. He also pointed out the importance of security in limiting access to servers. Additionally, he emphasized the reconciliation mechanism, which offers numerous benefits compared to imperative méthodes.

he expects the working group to converge on a common understanding of the methodology and to define APIs to manage GitOps.

RGS indicated that Vodafone already implemented the GitOps methodology especially for infrastructure management and for simple CNFs. Although most automated deployment operations rely on imperative methods and orchestrators, they have begun the implementation of GitOps.
