Helm

Helm Charts

• Bundle of YAML Files
• Configuration of database apps, monitoring apps etc. can be saved in Helm charts and reuse these configurations
• Create your own HRML charts with Helm
• Push them to Helm Repository
• Download and use existing ones

It's also used as templating engine. Instead of writing docker files for many microservices we can create a template with variables and use it as templates.

Variables defined like

image: {{ .Values.container.name }} 

and in values.yaml file we set

image: my-app-image
