Helm‑charts is een begrip binnen de industriële digitalisering en softwaredeployment & architectuur.
Definitie
Helm-charts zijn package management templates voor Kubernetes applications die de deployment, configuration en management van complex containerized applications vereenvoudigen. Een chart is een collection van files die een related set van Kubernetes resources beschrijft, enabling reproducible application deployments.
Kenmerken
- Template engine: Go template syntax voor dynamic resource generation
- Package management: Versioned application packages met dependency management
- Configuration management: Values files voor environment-specific customization
- Release management: Application lifecycle management (install, upgrade, rollback)
- Repository system: Centralized chart distribution via chart repositories
- Dependency resolution: Automatic sub-chart dependency installation
- Hooks: Lifecycle hooks voor pre/post deployment actions
- Testing framework: Built-in testing capabilities voor chart validation
- Security scanning: Chart vulnerability assessment en security validation
Toepassing
Industrial application deployment:
- MES deployment: Production management system containerization
- Data collection: Time-series database deployment automation
- Quality tools: Statistical analysis application packaging
- Monitoring stacks: Observability tool deployment (Prometheus, Grafana)
Microservices deployment:
- Application stacks: Multi-service application deployment coordination
- Service mesh: Istio, Linkerd service mesh deployment
- API gateways: Ingress controller en API management deployment
- Configuration management: Environment-specific configuration deployment
Development workflows:
- CD tooling: Jenkins, GitLab CI pipeline deployment
- Development environments: Standardized development stack deployment
- Testing environments: Automated test environment provisioning
- Staging deployments: Pre-production environment management
Third-party software:
- Database deployments: PostgreSQL, MongoDB, Redis deployment automation
- Message brokers: RabbitMQ, Apache Kafka deployment packages
- Caching solutions: Redis, Memcached deployment automation
- Security tools: Vault, certificate management deployment
