Helmfile
Helmfile is a declarative deployer and release orchestrator for Kubernetes. It acts as a wrapper for Helm, enabling the management and installation of multiple charts across one or more clusters using a single declarative configuration file.
The tool orchestrates the deployment of collections of charts and coordinates updates to ensure consistent cluster states. It also functions as a job runner, allowing the execution of one-shot tasks and database migrations as dedicated releases.
The system handles multi-cluster application management and infrastructure orchestration through environment-specific variable resolution and template-based value injection. It manages the desired state of multiple services by normalizing manifest paths and executing Helm commands as subprocesses.
Features
- Declarative Release Managers - Provides a declarative release manager that defines and versions Kubernetes Helm releases from YAML files.
- Helm Release State Reconciliation - Converges actual Helm releases to a desired state to automate the deployment of dependent services.
- Declarative Infrastructure Definitions - Uses declarative infrastructure definitions to automate the deployment of multiple Kubernetes services.
- Helm Chart Management - Automates the installation and lifecycle of packaged Kubernetes applications through a declarative interface.
- Helm Chart Deployment - Enables the installation of containerized applications using Helm templates via a declarative specification.
- Helm Configuration Wrappers - Provides a declarative layer that simplifies complex multi-chart deployments by managing Helm values.
- Multi-Cluster Deployment Managers - Provides centralized control for orchestrating application rollouts across multiple Kubernetes clusters.
- Release Orchestrators - Coordinates the installation and updates of multiple Kubernetes releases to ensure consistent cluster states.
- Environment Variable Sets - Supports loading distinct configuration sets to switch between different deployment contexts and Kubernetes clusters.
- Template-Based Variable Injection - Injects environment variables and merged value files into Helm templates for dynamic deployment configuration.
- Release Orchestrations - Orchestrates the deployment of a collection of charts across multiple clusters using a single declarative file.
- One-Time Job Executions - Triggers one-time tasks, such as database migrations, as dedicated Helm release jobs.
- Kubernetes Job Execution - Executes one-off workflow tasks as isolated Kubernetes jobs within a cluster.
- Lifecycle Job Runners - Runs database migrations and seeding as one-shot containerized jobs triggered during deployment.
- Continuous Delivery and GitOps - Tool for managing Helm charts as code.
