Asterisk as a Virtual Network Function Part 2

  1. 1. For Astricon 2017 Leif Madsen & Doug Smith Red Hat, Inc. A VNF-Asterisk Demo
  2. 2. 2 10:45 - Intro to NFV & VNF-Asterisk 11:30 - A VNF-Asterisk Demo 1:45 - Infrastructure Deployment 2:30 - Application Deployment TODAY’S AGENDA
  3. 3. 3 Show containers in Kubernetes Connect applications Make a phone call! WHAT’S THE GIST? We’re going to show VNF-Asterisk running in Kubernetes!
  4. 4. A FOCUS ON KUBERNETES
  5. 5. 5 ● Share the host operating system’s kernel ● Container images package an application’s run-time requirements ● Containers are instances of those images, typically running a single process per each container CONTAINERS, WHAT!? Containers isolate software from its surroundings. ?
  6. 6. 6 ● You specify how your applications run, and Kubernetes keeps instances of it running for you. ● Scale applications based on resource consumption ● First release in 2014, using lessons learned from Google’s Borg ● Red Hat is second largest contributor after Google itself KUBER-WHAT-EZE? Kubernetes, at its core, is a way to orchestrate how your containers run.
  7. 7. 7 OPENSHIFT Kubernetes for the enterprise ● Just running Kubernetes alone is like using Linux-From-Scratch instead of your favorite distro ● Promotes best practices and has already worried about things for you in advance ● Loaded with tools for a DevOps philosophy
  8. 8. 8 ● It could be just VMs! ● It could just be Docker! ● It could be Bare Metal! But, it’s not the only way! You can run VNF-Asterisk in plenty of ways, that’s part of how we explore it. Intersection in Makati City, the Philippines, Wikipedia
  9. 9. WHERE ARE THE GAPS?
  10. 10. 10 They’re all over! We have gaps and flexibility here on purpose. But, there’s certain a number of gaps that we’re interested in. Some of them are, from a Kubernetes perspective: ● The kube-proxy doesn’t honor UDP (at least not the way that we want it) ● Multi-interface support in Kubernetes is still burgeoning ● We didn’t touch IPv6 with a 10-foot pole PLEASE MIND THE GAPS! These technology gaps are part of why we’re exploring VNFs using Asterisk. "Mind the gap" tile mosaic at Victoria station in London, Wikipedia
  11. 11. SO, WHAT’S IN THE RECIPE?
  12. 12. INSERT DESIGNATOR, IF NEEDED12 Container Orchestration KUBERNETES VoIP monitoring and analytics HOMER WHAT TECH ARE YOU ROLLING? Some new -- some classics. VNF-ASTERISK Asterisk (w/ Sorcery) + Controller + Service Discovery
  13. 13. INSERT DESIGNATOR, IF NEEDED13 AND ANSIBLE! ● Agentless configuration management ● Requires only SSH on remote node, and Python ● “Playbooks” defined in easy-to-read YAML ● Excellent documentation!!
