Version and Branching

As of now, this helm-charts repository maintains 3 branches:

  • main (Version is 2.x.x for both version and appVersion in Chart.yaml)
  • 1.x (Version is 1.x.x for both version and appVersion in Chart.yaml)
  • gh-pages (Reserved branch for publishing helm-charts through github pages)

Contributors should choose the corresponding branch(es) when commiting their change(s):

  • If you have a change for a specific version, only open PR to specific branch
  • If you have a change for all available versions, first open a PR on main, then open a backport PR with [backport 1.x] in the title, with label backport 1.x, etc.
  • No changes should be commited to gh-pages by any contributor, as this branch should be only changed by github actions chart-releaser

Kubernetes Version Support

  • This helm-chart repository is tested with kubernetes version 1.19 and above

Installation

To install the OpenSearch Helm charts, execute the following commands:

helm repo add opensearch https://opensearch-project.github.io/helm-charts/
helm repo update

Once the charts repository reference is added, you can run the following command to see the charts.

helm search repo opensearch

You can now deploy charts with this command.

helm install my-deployment opensearch/<chart name>

Please see the README.md in the OpenSearch and OpenSearch Dashboards directories for installation instructions.

Breaking Change

For OpenSearch Chart version 2.18.0 and App Version OpenSearch version 2.12.0 and above require a custom strong password to be provided in order to setup demo admin user during the first time cluster installation, without this password the cluster would not spin up, unless demo config install is disabled or the cluster security settings are handled by the user.

Note: This won’t impact users who have already installed the cluster and created the security index. It only affects users starting a brand new cluster with OpenSearch version 2.12.0 and above.

The custom admin password can be supplied by adding the environment variable OPENSEARCH_INITIAL_ADMIN_PASSWORD in the value.yml as:

extraEnvs:
  - name: OPENSEARCH_INITIAL_ADMIN_PASSWORD
    value: <strong-password>

or during the installation example as helm install opensearch opensearch/opensearch --set extraEnvs[0].name=OPENSEARCH_INITIAL_ADMIN_PASSWORD,extraEnvs[0].value=$OPENSEARCH_INITIAL_ADMIN_PASSWORD

Notes About Default Installation

By default, on startup, the install_demo_configuration.sh is run via the opensearch-docker-entrypoint.sh script if DISABLE_INSTALL_DEMO_CONFIG is not true.

If custom certificates are used and allow_unsafe_democertificates is set to false in the configuration, this can prevent pods from starting with the following error: Demo certificates found but plugins.security.allow_unsafe_democertificates is set to false.

This can be solved by adding an environment variable in the value.yml:

extraEnvs:
  - name: DISABLE_INSTALL_DEMO_CONFIG
    value: "true"
