SBK Kubernetes Deployments

The SBK with preconfigured storage driver can be deployed as Kubernetes pod. As an example, to deploy rabbitmq SBK pod, you can refer to the file: https://github.com/kmgowda/SBK/blob/kmg-kubernetes-2/config/kubernetes/sbk-rabbitmq-k8-sample.sh and configuration file : https://github.com/kmgowda/SBK/blob/kmg-kubernetes-2/config/kubernetes/sbk-rabbitmq-k8-sample.yaml. Make sure that you use the appropriate IP address of RabbitMQ server.

Kubernetes setup with Dockers Desktop and Web Dashboard

  1. If you already have the Oracle Virtual box and minikube installed in your system, then I suggest uninstall them to avoid compatibility issues with docker desktop.
  2. Install Docker Desktop
  3. Enable the Kubernetes in Docker desktop . Path: Docker Dashboard -> settings -> Kubernetes
  4. Set up the kubernetes Dashboard, using below command:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
  1. Start the kubectl Proxy using below command:
kubectl proxy

  1. Now try to log-in to local host dashboard using browser, copy & paste the link: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login

  2. The browser asks the authentication login, to get the authentication login token using the below command:

kubectl -n kube-system describe secret default

This command displays the token which is generally a larger size string, copy it and use it for authentication of step 6. link: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login

SBK docker image with Kubernetes and command line arguments

you can directly run the SBK image with command line arguments , below is an example

kubectl run sbk --restart=Never --expose=true  --port=9718 --hostport=9718  --image=kmgowda/sbk:latest -- -class  rabbitmq  -broker 192.168.0.192 -topic kmg-topic-11  -writers 5  -readers 1 -size 100 -seconds 60

to pass the command line arguments to SBK image , "--" prefix is used before -class argument.

Example benchmarking command for a file write with busy box is as follows:

kubectl run sbk --restart=Never --expose=true  --port=9718 --hostport=9718  --image=kmgowda/sbk:latest -- -class  file  -writers 1  -size 100 -seconds 60
