#Cluster creation steps ####1. Create the s3 bucket to store the state data of the cluster, lets name it “opensearch-kube-state-store” for the example. In your case it should be another (all s3 storages must have unique names) ####2. Download the kops ####3. Optional(create the route53 if you want to use the specific dns zone, we can use the gossip connection otherwise) ####4. Export name and state store of the cluster like so: export NAME=opensearch.k8s.local
export KOPS_STATE_STORE="s3://opensearch-kube-state-store" #####k8s.local means the cluster will use the gossip connection ####5. Create the cluster using kops create cluster --zones=us-east-1a,us-east-1d --cloud=aws --master-size=t2.medium --name=${NAME} ####6. Get the configuration files Clone the git repository with configuration files using git clone https://github.com/danyilp/opensearch-ku.git ######Open the git folder cd opensearch-ku ####7. After 5th step cluster is not yet created, to finish the creation of the cluster we must use kops update cluster --name ${NAME} --yes --admin ###But! before this we want to configure the instance groups for the nodes. #####First of all delete the default nodes instance-group since we’ll be creating the cluster in the us-east it should look like kops delete ig --name=${NAME} nodes-us-east-1a #####then create 2 new instance groups for master and data nodes kops create -f ig_master.yaml

kops create -f ig_data.yaml

#####After it run the kops update cluster --name ${NAME} --yes --admin ####8. Wait until cluster is created you can check it using kops validate cluster --wait 10m ####9. Install the Helm charts ######1. Get OpenSearch chart helm repo add opensearch https://opensearch-project.github.io/helm-charts/

helm repo update ######2. Install the helm charts helm install opensearch-master-us-east-1 opensearch/opensearch -f master.yaml

helm install opensearch-data-us-east-1 opensearch/opensearch -f data.yaml ####10. Use the cluster #####To get the cluster endpoint you can use kubectl get services opensearch-cluster-master-us-east-1
