Helm charts and Operators can solve similar problems by providing an easy way to automate deployment of applications or infrastructure software in a Kubernetes cluster. What is the deciding factor on which to use? Both Helm and Operators can work at different points to achieve a desired but different goal.
Let’s explore some of the differences and similarities they both offer to help you along your journey.
|Use cases||Optimized for individual users deploying applications in a specific project.||Optimized for administrators deploying and maintaining cluster-wide services.|
|Customization||Some scope for customization. Charts allow users to provide values specific to their environment.||Greater scope for customization. More complex operations, workflow and event-driven automation, lifecycle management can be added.|
|Development investment||Shorter development time to build.||Longer development time to build. Operator SDK provides tools to assist in the process.|
|Automation scope||Good for day-1 operations such as installing the application and performing simple updates.||Provides a broad spectrum of day-1 and day-2 automation capabilities, for full lifecycle management of the application.|
