Deploying ElasTest with Kubernetes

How to run ElasTest on K8s (EK mode)

Get the ElasTest Manifests
  • Clone toolbox project
git clone https://github.com/elastest/elastest-toolbox.git

  • Navigate to folder
cd elastest-toolbox/kubernetes/ek
Enable Security

If you want to stablish credentials to access to ElasTest and its integrated services, follow these steps:

  • Set Jenkins and TestLink Credentials. Edit the file etm-deployment.yml and replace the value "none" in the variables ET_USER and ET_PASS for whatever you want.
- name: ET_USER
  value: XXXXXX
- name: ET_PASS
  value: YYYYYY

  • Set ElasTest Credentials. Edit the file "etm-proxy-deployment.yml" and replace the value "none" in the variables ET_USER and ET_PASS for whatever you want.
- name: ET_USER
  value: XXXXXX
- name: ET_PASS
  value: YYYYYY

In addition, you have to set to true the variable ET_SECURITY.

- name: ET_SECURITY
  value: "true"

It is possible that when you start with this mini tutorial, you don't have Minikube and the necessary tools installed. To know how to do this, please follow the steps in described in the official site

Minikube in Ubuntu host (without a VM)

Run Minikube with this command in your local:

sudo minikube start --memory=4098 --cpus=4 --vm-driver=none --apiserver-ips 127.0.0.1 --apiserver-name localhost --extra-config=kubelet.resolv-conf=/run/systemd/resolve/resolv.conf --extra-config=apiserver.service-node-port-range=1000-60000
Deploy ElasTest
kubectl create -f . -f volumes/

Note: -f volumes it’s only necessary first time, but there is no problem if it is used at another time, although error messages will be output*

Minikube in VM

Run Minikube with this command in your local:

sudo minikube start --memory=6048 --cpus=4 --extra-config=apiserver.service-node-port-range=1000-60000 --extra-config kubelet.node-ip=VM-IP
Deploy ElasTest
  • Set the Public Node IP in ElasTest Edit the file etm-deployment.yml and update this environment variable with the VM IP:

    - name: ET_PUBLIC_HOST
      value: VM IP
    
  • Start ElasTest

    kubectl create -f . -f volumes/
    

    Note: -f volumes it’s only necessary first time, but there is no problem if it is used at another time, although error messages will be output*

How to access
  • Execute sudo minikube ip to get the cluster ip.
  • Open your browser and navigate to http://CLUSTER-IP:37000

If you want to deploy ElasTest on a k8s cluster in AWS (in a single node), you will need to do something else before executing the command to start ElasTest on k8s.

Cluster Configuration
  • Extend default NodePort range Add this line --service-node-port-range=1000-40000 to the file /etc/kubernetes/manifests/kube-apiserver.yaml.
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null
labels:
    component: kube-apiserver
    tier: control-plane
name: kube-apiserver
namespace: kube-system
spec:
containers:
- command:
    - kube-apiserver
    - --advertise-address=10.1.47.54
    ……
    - --service-node-port-range=1000-40000
Deploy ElasTest
  • Set the Public Node IP in ElasTest Edit the file etm-deployment.yml and update this environment variable with the public ip for the node in AWS:

    - name: ET_PUBLIC_HOST
      value: AWS Public Node IP
    
  • Start ElasTest

    kubectl create -f . -f volumes/
    

    Note: -f volumes it’s only necessary first time, but there is no problem if it is used at another time, although error messages will be output*

How to access
  • Use the AWS public IP as your cluster IP.
  • Open your browser and navigate to http://CLUSTER-IP:37000
How to stop:
kubectl delete -f .

Note: don't include the volumes folder if you don't want to lose the elastest data, as the volumes will be deleted
