Learn OPENSHIFT-TEMPLATES with Real Code Examples

Templates exist as YAML/JSON objects stored in projects or Git

`oc process` renders parameters into concrete OpenShift resources

`oc apply` or `oc create` instantiates the objects

Parameters allow customization at runtime

Templates can reference images, secrets, config maps, and other OpenShift objects

Template defines objects and parameters

`oc process` resolves parameters into concrete objects

`oc apply` creates or updates resources

Objects deployed in OpenShift project/namespace

Parameters allow environment-specific customization

Template as a modular resource bundle

Parameter-driven customization

Integration with CI/CD and GitOps pipelines

OpenShift-native object definitions

Support for multi-object instantiation in one step

Multi-tier microservices deployment

CI/CD pipeline bootstrapping

Standardized developer environment provisioning

Environment-specific staging and production deployments

Integration with image streams and build pipelines

Declarative definition of resources

Parameterization for flexibility

Reusability across environments
