What are top Helm instruments and tools?

• Helm CLI: Helm is a package manager for Kubernetes, allowing users to easily install, upgrade, and manage applications running on Kubernetes clusters. It was first released in 2015 and has since become one of the most widely used tools in the Kubernetes ecosystem. The Helm CLI provides a command-line interface to interact with Helm, enabling users to create, package, deploy, and manage Helm charts, which are the packages that contain all the necessary Kubernetes manifests and configuration files.
• Helm Charts: Helm charts are the packages used by Helm to deploy applications on Kubernetes. A Helm chart contains all the necessary Kubernetes manifest files, along with configuration values that can be customized during the deployment process. Charts can be used to deploy a wide range of applications and services, from simple web applications to complex microservices architectures. The Helm chart format has become the de facto standard for packaging and distributing Kubernetes applications.
• Helm Hub: Helm Hub is a centralized repository for Helm charts, serving as a marketplace where users can discover, share, and download Helm charts. It provides a user-friendly interface for searching and browsing Helm charts, making it easy to find pre-built charts for popular applications and services. Helm Hub also allows users to publish their own charts, enabling the community to contribute and collaborate on the development of Helm charts.
• Helmfile: Helmfile is a declarative tool for deploying and managing Helm charts. It allows users to define their application deployments in a YAML file, specifying the desired state of the deployed resources. Helmfile simplifies the deployment process by handling the installation, upgrade, and deletion of Helm charts based on the defined configuration. It provides a convenient way to manage complex deployments with multiple Helm releases and dependencies.
• Helm Operator: Helm Operator is an operator for Kubernetes that allows the deployment and management of Helm charts using Kubernetes custom resources. It extends the functionality of Helm by leveraging the Kubernetes API and controller framework to automate the deployment and lifecycle management of Helm charts. With Helm Operator, users can define custom resources that represent Helm releases and use them to deploy and manage applications on Kubernetes.
• ChartMuseum: ChartMuseum is an open-source Helm chart repository server that can be used to host and distribute Helm charts. It provides an HTTP API for uploading, downloading, and managing Helm charts, making it easy to create and deploy private Helm repositories. ChartMuseum supports various storage backends, including local file systems, cloud storage services, and object storage systems, providing flexibility in terms of hosting and scaling Helm chart repositories.
• Kustomize: Kustomize is a tool that allows users to customize, patch, and manage Kubernetes manifests without modifying the original files. It provides a declarative approach to managing configuration overlays, enabling users to define changes to the base Kubernetes manifests using simple YAML files. Kustomize integrates well with Helm, allowing users to combine the power of both tools for managing complex deployments and configurations.

Cases when Helm does not work

1. The Helm chart is not compatible with the Kubernetes version: Helm relies on the Kubernetes API for managing deployments, and sometimes there can be compatibility issues between different versions. If you are using an older version of Kubernetes, certain Helm features may not work as expected.
2. Incorrect or missing dependencies: Helm charts often rely on other charts or packages to function properly. If these dependencies are not correctly specified or are missing, Helm may encounter errors and fail to deploy the desired resources.
3. Insufficient resources: Helm deployments require a certain amount of system resources to function properly. If the cluster or node where the deployment is being attempted does not have enough resources (CPU, memory, etc.), Helm may fail to deploy the desired resources.
4. Conflicts with existing resources: Helm may fail to deploy resources if there are conflicts with existing resources in the cluster. For example, if you are trying to deploy a service with the same name as an existing service, Helm will fail to create the new service.
5. Networking issues: Helm deployments rely on network connectivity between the Helm client and the Kubernetes cluster. If there are network issues, such as firewalls blocking communication or connectivity problems, Helm may not be able to deploy resources.
6. Incorrect configuration values: Helm deployments often require configuration values to be provided, such as usernames, passwords, or other settings. If these values are not correctly specified or are missing, Helm may fail to deploy resources or deploy them incorrectly.
7. Errors in the Helm chart: Helm charts are created by developers, and like any software, they can contain bugs or errors. If there are issues with the Helm chart itself, such as syntax errors or incorrect configuration, Helm may fail to deploy the desired resources.
8. Insufficient permissions: Helm requires certain permissions to perform deployments in a Kubernetes cluster. If the user or service account used by Helm does not have the necessary permissions, Helm will fail to deploy resources.
