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:

  • https://github.com/roboll/helmfile
  • https://www.codegrepper.com/code-examples/shell/helmfile+install+ubuntu

      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>
