Ixia-C Deployment Using Helm Chart

Step1: Kubernetes cluster creation

  1. Deploy a clean instance of Ubuntu Server VM with following prerequisites:

    • Recommended 4 CPU cores (Controller with one TE)
    • Recommended 10GB RAM

  2. Login to newly deployed server and get helper scripts.

        git clone http://gitlab.it.keysight.com/athena/scripts.git
    cd scripts/kne && chmod +x ./kne.sh

  3. Install prerequisites and setup kubeadm cluster.

    • comment out meshnet, go and kne part in kne.sh
        ./kne.sh setup
    • ensure all pods are up and running and kubectl will be installed automatically as part of kubeadm setup
        kubectl get pods -A

Step2: Install helm

    curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
    chmod 700 get_helm.sh
    ./get_helm.sh

Step3: Install helmfile

  • References:

        wget -O helmfile_linux_amd64 https://github.com/roboll/helmfile/releases/download/v0.135.0/helmfile_linux_amd64
    chmod +x helmfile_linux_amd64
    mv helmfile_linux_amd64 ~/.local/bin/helmfile

    OR

    Install brew package in ubuntu

        sudo apt update
    sudo apt-get install build-essential
    sudo apt install git -y
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
    eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"
    brew doctor
    brew install gcc

    Install helmfile

        brew install helmfile

Step4: Interface Creation

    sudo ip link add veth1 type veth peer name veth2
    sudo ip link set veth1 up
    sudo ip link set veth2 up

Step5: Deployment using helmfile

  • add helm chart repo
    helm repo add <local_repo_name> <location_of_helm_chart>

Ex-

    helm repo add helm https://shramroy.github.io/helm
  • check all the local helm chart repo list
    helm repo list -a
  • search helm charts
    helm search repo <local_repo_name>
  • check helm envioronment variables
   helm env
  • check the releases of helm chart based on the namespace
   helm list -a
  • check all contents(in chart.yaml & values.yaml) for a specific helmchart
    helm show all helm/my-chart
  • check contents in Chart.yaml for a specific helmchart
    helm show chart helm/my-chart
  • check contents in values.yaml for a specific helmchart
    helm show values helm/my-chart
  • check the details about the release of helm chart
    helm status <release_name>

  • Get samples of helmfile (b2b, dise)

  • Edit the 'chart' in helmfile.yaml based on the local location of the helm chart for that topology Ex-

    releases:
- chart: helm/ixia-c

  • Modify helmfile based on requirements like interace & port details

  • Deployment/Install:

    • Go to specific topology directory
        cd topologies/b2b
    • Run:
        helmfile sync

  • Delete/Uninstall:

    • Update helmfile.yaml with installed: false for application(s)

    • Run:

        helmfile sync

  • Use exposed services on given Nodeports:

    • Execute the following command to know the nodeports of exposed serives
    • Run:
        kubectl get svc -n <namespace_name>
