Asterisk as a Virtual Network Function Part 4
- 1. For Astricon 2017 Leif Madsen & Doug Smith Red Hat, Inc. VNF-Asterisk, Deploying The Applications
- 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. INSERT DESIGNATOR, IF NEEDED3 The container images Kubernetes Resource Definitions TroubleshootingRun the deployment WHAT SHALL WE LOOK AT? The pieces involved in deploying the VNF-Asterisk applications themselves.
- 5. INSERT DESIGNATOR, IF NEEDED5 dougbtv/docker-asterisk DOCKER-ASTERISK sipcapture/homer-docker HOMER-DOCKER WHERE ARE THE DOCKERFILES? The Dockerfiles are on Github, of course! And the images on Dockerhub. VNF-ASTERISK-CONTROLLER dougbtv/vnf-asterisk-controller *
- 6. INSERT DESIGNATOR, IF NEEDED6 DISSECTING A DOCKERFILE Each instruction results in an image layer FROM: A base image RUN: Commands ENV: Environment vars
- 7. INSERT DESIGNATOR, IF NEEDED7 THE OPEN CONTAINER INITIATIVE Docker isn’t the only way.
- 9. 9 In Kubernetes pods live together with the namespaces of an “infra-container” which shares their network & volume mounts, and more. WHAT’S A POD? Pods are logically grouped containers and scale together in deployments. Pod Asterisk (VoIP) Capture Agent (packet sniffer) Network Volumes ... container container
- 10. 10 INSIDE A POD SPEC... It’s really just YAML that specifies how to run a pod. kind: The type of specification image: Which image to run volumeMounts: storage to mount configMap: configurations to mount
- 11. 11 DEPLOYMENTS AND REPLICAS Deployment controllers provide updates to ReplicaSets and Pods Pod-1 Asterisk (VoIP) Capture Agent container container Replica Set Replicas: 2 Pod-2 Asterisk (VoIP) Capture Agent container container 2 instances of Asterisk, please. Deployment: Asterisk
- 12. 12 INSIDE A DEPLOYMENT DEFINITION It abstracts a replication controller & pod specs so you can scale it. kind: It’s a deployment replicas: Number of instances template: What to replicate spec: The whole pod spec (as before)
- 13. 13 CONFIGMAPS How to pack (primarily) static configuration files (or environment vars, and more) into pods. kind: A config map. data: A dictionary of configs These are config files packed into the yaml file! Here’s some friendly ones you know and love (like pjsip.conf and cdr.conf)
- 14. DEMO TIME!
- 15. TROUBLESHOOTING
- 16. BONUS! TAKE THE HIGH ROAD
- 17. 17 DO YOU LIKE THE EASY WAY OUT? You can also run VNF-Asterisk solely with Docker-Compose! $ dnf install -y docker-compose $ git clone https://github.com/dougbtv/docker-asterisk.git $ docker-compose build $ docker-compose up

- 20. 20 VNF-Asterisk is a VNF utilizing Asterisk (an Open Source telephony framework) and intended to be used for validating environments, and exploring topics such as: ● VNFs in COEs (Kubernetes / Openshift) ● Container Networking ● Scale ● High Availability ● And more. SO, WHAT IS VNF-ASTERISK? A demo VNF in Kubernetes that YOU can try out! redhat-nfvpe/vnf-asterisk
