opensearch-dashboards

OpenSearch Dashboards Helm Chart

This Helm chart installs OpenSearch Dashboards with configurable TLS, RBAC and much more configurations. This chart caters to a number of different use cases and setups.

• Requirements
• Installing
• Uninstalling

Requirements

• 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.

Installing

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/opensearch-dashboards

The command deploys OpenSearch Dashboards with its associated components 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.

Uninstalling

To delete/uninstall the chart with the release name my-release:

helm uninstall my-release

ingress	Configurable [ingress][] to expose the OpenSearch service. See [values.yaml][] for an example	see [values.yaml][]
labels	Configurable [labels][] applied to all OpenSearch pods	{}
nameOverride	Overrides the clusterName when used in the naming of resources	""
nodeSelector	Configurable [nodeSelector][] so that you can target specific nodes for your OpenSearch cluster	{}
podAnnotations	Configurable [annotations][] applied to all OpenSearch pods	{}
podSecurityContext	Allows you to set the [securityContext][] for the pod	see [values.yaml][]
priorityClassName	The name of the [PriorityClass][]. No default is supplied as the PriorityClass must be created first	""
rbac	Configuration for creating a role, role binding and ServiceAccount as part of this Helm chart with create: true. Also can be used to reference an external ServiceAccount with serviceAccountName: "externalServiceAccountName"	see [values.yaml][]
resources	Allows you to set the [resources][] for the StatefulSet	see [values.yaml][]

securityContext	Allows you to set the [securityContext][] for the container	see [values.yaml][]
service.annotations	[LoadBalancer annotations][] that Kubernetes will use for the service. This will configure load balancer if service.type is LoadBalancer	{}
service.headless.annotations	Allow you to set annotations on the headless service	{}
service.externalTrafficPolicy	Some cloud providers allow you to specify the [LoadBalancer externalTrafficPolicy][]. Kubernetes will use this to preserve the client source IP. This will configure load balancer if service.type is LoadBalancer	""

service.labelsHeadless	Labels to be added to headless service	{}
service.labels	Labels to be added to non-headless service	{}
service.loadBalancerIP	Some cloud providers allow you to specify the [loadBalancer][] IP. If the loadBalancerIP field is not specified, the IP is dynamically assigned. If you specify a loadBalancerIP but your cloud provider does not support the feature, it is ignored.	""

tolerations	Configurable [tolerations][]	[]
updateStrategy	The [updateStrategy][] for the StatefulSet. By default Kubernetes will wait for the cluster to be green after upgrading each pod. Setting this to OnDelete will allow you to manually delete each pod during upgrades	RollingUpdate
extraObjects	Array of extra K8s manifests to deploy	list []
autoscaling	Prerequisite: Install/Configure metrics server, to install use kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml, See https://github.com/kubernetes-sigs/metrics-server.
