before deployment Kustomize vs Helm vs OpenShift Templates Patching framework Ability to apply yaml directly Some use-cases may work better with templates No support in OpenShift GUI console Great for not as good for independent applications Kubernetes focused package manager based on templates Templates enable prescribed customization, more difficult to customize outside those boundaries templating solution Easy to understand and use First class support in OpenShift GUI console Templates are static, no support for dynamic scripting/variables What's next in OpenShift Q3CY2020 Cloud

Kubernetes. It runs on the concept of Helm Charts and Templates, which are shown below. When the Templates are combined with the values, these templates will help to generate valid Kubernetes manifests charts #Required ├── Chart.yaml #Required ├── templates #Required │ ├── deployment.yaml │ ├── _helpers.tpl │ ├── hpa

in your cluster. It can also be used for your own deployments. Helm works by marrying a set of templates for Kubernetes manifests along with their runtime values that are merged to create the end result you have values for different environments, you don’t keep them in the same place as the templates. The templates (the chart itself) is stored in a chart repository and the specific values for each environment

templatized versions of your YAML manifests. You can inject values into the parameters defined in the templates, and Helm injects these values into the manifests to create a release. A release is the end- Chapter
