#Template Defaults
> v3.1 and after

## Introduction

`TemplateDefaults` feature enables the user to configure the default template values in workflow spec level that will apply to all the templates in the workflow. If the template has a value that also has a default value in `templateDefault`, the Template's value will take precedence. These values will be applied during the runtime.

## Configuring `templateDefaults` in WorkflowSpec

For example:
```yaml
apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  name: template-defaults-example
spec:
  entrypoint: main
  templateDefaults:
    timeout: 30s   # timeout value will be applied to all templates
    retryStrategy: # retryStrategy value will be applied to all templates
      limit: 2
  templates:
  - name: main
    container:
      image: docker/whalesay:latest
```

## Configuring `templateDefaults` in Controller Level
Operator can configure the `templateDefaults` in [workflowDefaults](default-workflow-specs.md). This `templateDefault` will be applied to all the workflow which runs on the controller.

The following would be specified in the Config Map:

```yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: workflow-controller-configmap
data:
  # Default values that will apply to all Workflows from this controller, unless overridden on the Workflow-level
  workflowDefaults: |
    metadata:
      annotations:
        argo: workflows
      labels:
        foo: bar
    spec:
      ttlStrategy:
        secondsAfterSuccess: 5
      templateDefaults:
        timeout: 30s 
```
