. For example the following command sets the replicas
of the kube-state-metrics Pods to 2
.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
Tip: You can use the default values.yaml
Configuration and installation details¶
Rolling vs Immutable tags¶
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
Use Sidecars and Init Containers¶
If additional containers are needed in the same pod (such as additional metrics or logging exporters), they can be defined using the sidecars
config parameter. Similarly, extra init containers can be added using the initContainers
parameter.
Refer to the chart documentation for more information on, and examples of, configuring and using sidecars and init containers.
Set Pod affinity¶
This chart allows you to set custom Pod affinity using the affinity
parameter. Find more information about Pod's affinity in the Kubernetes documentation.
As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset
, podAntiAffinityPreset
, or nodeAffinityPreset
parameters.
Troubleshooting¶
Find more information about how to deal with common errors related to Bitnami's Helm charts in this troubleshooting guide.
Upgrading¶
To 3.0.0¶
This major release renames several values in this chart and adds missing features, in order to be aligned with the rest of the assets in the Bitnami charts repository.
Affected values:
service.port
was renamed asservice.ports.metrics
.service.nodePort
was renamed asservice.nodePorts.metrics
.securityContext
was split inpodSecurityContext
andcontainerSecurityContext
.- Removed unused value
rbac.apiVersion
.
To 2.0.0¶
This version updates kube-state-metrics to its new major, 2.0.0. There have been some value's name changes to acommodate to the naming used in 2.0.0:
.Values.namespace
->.Values.namespaces
.Values.collectors
->.Values.kubeResources
For more information, please refer to kube-state-metrics 2 release notes.
To 1.1.0¶
This version introduces bitnami/common
, a library chart as a dependency. More documentation about this new utility could be found here. Please, make sure that you have updated the chart dependencies before executing any upgrade.
To 1.0.0¶
On November 13, 2020, Helm v2 support formally ended. This major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
