ignite_setup_stateless

Follow these steps

• • install eksctl
• • install kubectl

eksctl create cluster --name ignitecluster --nodes 2 --nodes-min 1 --nodes-max 4

Now check the cluster and the service by using commands

eksctl get cluster -n ignitecluster

kubectl get svc

create namespace

kubectl create namespace ignite

create service

kubectl create -f service.yaml

create service name

kubectl create sa ignite -n ignite

create cluster role

kubectl create -f cluster-role.yaml

create node configuration

kubectl create configmap ignite-config -n ignite --from-file=node-configuration.xml

Create the StatefulSet by running the following command:

  kubectl create -f statefulset.yaml

Check if the pods were deployed correctly:

kubectl get pods -n ignite

Check if the ignite were deployed correctly (eg):

kubectl logs ignite-cluster-5b69557db6-lcglw -n ignite

Since you are using persistence, you must activate the cluster after it is started. To do that, connect to one of the pods:

kubectl exec -it <pod_name> -n ignite -- /bin/bash

Execute the following command:

/opt/ignite/apache-ignite/bin/control.sh --set-state ACTIVE --yes

scale the cluster

kubectl scale sts ignite-cluster --replicas=3 -n ignite

Get the public IP of the service:

$ kubectl describe svc ignite-service -n ignite

Connecting to REST API

Connect to the cluster’s REST API as follows:

$ curl http://13.86.186.145:8080/ignite?cmd=version
{"successStatus":0,"error":null,"response":"2.10.0","sessionToken":null}

to test the persistence

To start the test create a new environment ( to use python3) Follow this steps .

python3 -m venv /path/to/new/virtual/environment

source venv/bin/activate

pip3 install -r requirements.txt

and then run

python3 test_scipt.py

and then

python3 test_script_2.py
