This Helm chart installs OpenSearch with configurable TLS, RBAC and much more configurations. This chart caters a number of different use cases and setups.
- Kubernetes >= 1.14
- Helm >= 2.17.0
- We recommend you to have 8 GiB of memory available for this deployment, or at least 4 GiB for the minimum requirement. Else, the deployment is expected to fail.
Once you've added this Helm repository as per the repository-level README then you can install the chart as follows:
helm install my-release opensearch/opensearchThe command deploys OpenSearch with its associated components (data statefulsets, masters, clients) on the Kubernetes cluster in the default configuration.
NOTE: If using Helm 2 then you'll need to add the --name command line argument. If unspecified, Helm 2 will autogenerate a name for you.
To delete/uninstall the chart with the release name my-release:
helm uninstall my-release| Parameter | Description | Default |
