\n\n# Elasticsearch Helm Chart\n\nElasticsearch is a distributed, RESTful search and analytics engine capable of addressing a growing number of use cases. The Elasticsearch Helm chart automates deployment and configuration of Elasticsearch in Kubernetes clusters using Minimus images, managed by the Elastic Cloud on Kubernetes (ECK) operator.\n\n\n## {{icon-list-search}} Prerequisites\n\n- A subscription to the Minimus images included in the chart\n- A running Kubernetes cluster (v1.21 or higher is recommended)\n- `kubectl` installed and configured\n- Helm v3.8 or higher for OCI support ([Installation instructions](https://helm.sh/docs/intro/install/))\n- Cluster Admin privileges\n- The ECK operator installed in the cluster ([ECK operator chart](https://www.minimus.io/charts/eck-operator))\n\n**Note**: This chart creates an Elasticsearch Custom Resource managed by the ECK operator. The ECK operator and its CRDs must be installed before deploying this chart.\n\n

\n\n---\n\n

\n\n## {{icon-rocket}}Try It Out\n\nIn this example we will deploy Elasticsearch on a Kubernetes cluster using the Minimus Elasticsearch Helm chart. Elasticsearch will provide a single-node cluster ready for search and analytics workloads.\n\n

\n\n### Step 1: Start Cluster\n\n

\n\nIf you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. [Deployment instructions](https://minikube.sigs.k8s.io/docs/start/?arch=%2Flinux%2Fx86-64%2Fstable%2Fbinary+download)\n\n

\n\n### Step 2: Create Namespace\n\n

\n\nCreate a namespace:\n\n```\nkubectl create ns eck-elasticsearch\n```\n\n{{if-enterprise}}\n\nNext, create a Kubernetes secret for the Minimus token:\n\n```\nkubectl create secret docker-registry minimus-registry \\\n --docker-server=reg.mini.dev \\\n --docker-username=minimus \\\n --docker-password={{pull-token}} \\\n --namespace=eck-elasticsearch\n```\n\n{{/if-enterprise}}\n\n

\n\n### Step 3: Deploy the Helm Chart\n\n

\n\nDeploy the Minimus Helm chart:\n\n```\nhelm install my-eck-elasticsearch {{oci-url}} \\\n --version {{chart-version}} \\\n -n eck-elasticsearch \\\n --wait\n```\n\nIf you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using `-f values.yaml`:\n\n```\nhelm install my-eck-elasticsearch {{oci-url}} \\\n --version {{chart-version}} \\\n -f values.yaml \\\n -n eck-elasticsearch \\\n --wait\n```\n\n

\n\n### Step 4: Verify Elasticsearch is Running\n\n

\n\nConfirm the chart deployed successfully and Elasticsearch started:\n\n```\nkubectl get pods -n eck-elasticsearch\n```\n\nYou should see output similar to:\n\n```\nNAME READY STATUS RESTARTS AGE\nelasticsearch-es-default-0 1/1 Running 0 2m\n```\n\n

\n\n### Step 5: Test Elasticsearch Cluster Health\n\n

\n\nRetrieve the Elasticsearch password from the Kubernetes secret:\n\n```\nES_PASSWORD=$(kubectl get secret elasticsearch-es-elastic-user \\\n -n eck-elasticsearch \\\n -o go-template='{{.data.elastic | base64decode}}')\n```\n\nPort-forward to the Elasticsearch service:\n\n```\nkubectl port-forward svc/elasticsearch-es-http 9200:9200 -n eck-elasticsearch &\n```\n\nVerify the cluster health:\n\n```\ncurl -sk -u \"elastic:$ES_PASSWORD\" https://localhost:9200/_cluster/health?pretty\n```\n\nYou should see a response with `\"status\" : \"green\"` indicating the cluster is healthy.\n\n

\n\n### Step 6: Clean Up\n\n

\n\nUninstall the chart and delete the namespace to remove all resources:\n\n```\nhelm uninstall my-eck-elasticsearch -n eck-elasticsearch\nkubectl delete namespace eck-elasticsearch\n```\n\n

\n\nDeploy the full Elastic Stack (Elasticsearch, Kibana) as Kubernetes custom resources managed by the ECK Operator (Elastic Cloud on Kubernetes Operator). The ECK Stack Helm chart automates deployment and configuration of the Elastic Stack in Kubernetes clusters using Minimus images.\n\n\n## {{icon-list-search}} Prerequisites\n\n- A subscription to the Minimus images included in the chart\n- A running Kubernetes cluster (v1.21 or higher is recommended)\n- `kubectl` installed and configured\n- Helm v3.8 or higher for OCI support ([Installation instructions](https://helm.sh/docs/intro/install/))\n- Cluster Admin privileges\n- ECK Operator installed and running in your cluster ([Installation instructions](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-install-helm.html))\n\n**Note:** The ECK Operator must be installed before deploying the ECK Stack chart. The operator manages the lifecycle of Elasticsearch and Kibana resources created by this chart.\n\n

\n\n---\n\n

\n\n## {{icon-rocket}}Try It Out\n\nIn this example we will deploy the Elastic Stack on a Kubernetes cluster using the Minimus ECK Stack Helm chart. You will get a running Elasticsearch cluster and Kibana instance out of the box.\n\n

\n\n### Step 1: Start Cluster\n\n

\n\n### Step 2: Create Namespace\n\n

\n\nCreate a namespace:\n\n```\nkubectl create ns eck-stack\n```\n\n{{if-enterprise}}\n\nNext, create a Kubernetes secret for the Minimus token:\n\n```\nkubectl create secret docker-registry minimus-registry \\\n --docker-server=reg.mini.dev \\\n --docker-username=minimus \\\n --docker-password={{pull-token}} \\\n --namespace=eck-stack\n```\n\n{{/if-enterprise}}\n\n

\n\n### Step 3: Deploy the Helm Chart\n\n

\n\nDeploy the Minimus Helm chart:\n\n```\nhelm install my-eck-stack {{oci-url}} \\\n --version {{chart-version}} \\\n -n eck-stack \\\n --wait\n```\n\nIf you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using `-f values.yaml`:\n\n```\nhelm install my-eck-stack {{oci-url}} \\\n --version {{chart-version}} \\\n -f values.yaml \\\n -n eck-stack \\\n --wait\n```\n\n

\n\n### Step 4: Verify ECK Stack is Running\n\n

\n\nCheck the status of the Elasticsearch and Kibana resources:\n\n```\nkubectl get elasticsearch,kibana -n eck-stack\n```\n\nExpected output:\n\n```\nNAME HEALTH NODES VERSION PHASE AGE\nelasticsearch.elasticsearch.k8s.elastic.co/elasticsearch green 1 9.x.x Ready 2m\n\nNAME HEALTH NODES VERSION AGE\nkibana.kibana.k8s.elastic.co/eck-stack-eck-kibana green 1 9.x.x 2m\n```\n\nRun the following and wait for the pods to show that their status is `Running`:\n\n```\nkubectl get pods -n eck-stack -w\n```\n\n

\n\n### Step 5: Test Elasticsearch Health\n\n

\n\nRetrieve the default `elastic` user password:\n\n```\nkubectl get secret elasticsearch-es-elastic-user -n eck-stack \\\n -o go-template='{{.data.elastic | base64decode}}'\n```\n\nPort-forward to the Elasticsearch service:\n\n```\nkubectl port-forward svc/elasticsearch-es-http 9200 -n eck-stack\n```\n\nIn a separate terminal, verify the cluster health:\n\n```\ncurl -sSf -k -u \"elastic:\" \"https://localhost:9200/_cluster/health?pretty\"\n```\n\nYou should see `\"status\" : \"green\"` in the output.\n\n

\n\n### Step 6: Access Kibana\n\n

\n\nPort-forward to the Kibana service:\n\n```\nkubectl port-forward svc/eck-stack-eck-kibana-kb-http 5601 -n eck-stack\n```\n\nOpen `https://localhost:5601` in your browser and log in with:\n\n* Username: `elastic`\n* Password: (from the previous step)\n\n

\n\n### Step 7: Clean Up\n\n

\n\nUninstall the chart and delete the namespace to remove all resources:\n\n```\nhelm uninstall my-eck-stack -n eck-stack\nkubectl delete namespace eck-stack\n```\n\n
