Summary
Operators are important for ensuring that the desired state always matches the live state. Such a feat allows users to more easily maintain a source of truth for resource configuration. Users can leverage a Helm operator to provide this type of resource reconciliation, and it is easy to get started because it uses Helm charts as its deployment mechanism. When a CR is created, the Helm operator installs the associated Helm chart to create a new release. Subsequent upgrades are performed when the CR is modified, and the release is uninstalled when the CR has been deleted.
To manage the operator, cluster administrators can create a separate Helm chart for creating the operator’s resources and CRDs. Also, end users can create a separate Helm chart for creating CRs and other related resources.
In the next chapter, we will discuss best practices and topics around security within the Helm ecosystem.
