What are the TOSCA elements need to be added to requirements as per best practices
When writing TOSCA templates, it’s important to follow best practices to ensure that your templates are clear, concise, and easy to maintain. Some of the elements that should be included in your requirements for TOSCA templates include:
- Node Types: Define node types for each component of the application, including their properties, interfaces, and relationships. This will help ensure consistency and enable reuse of components across different applications.
- Topology Templates: Use topology templates to describe the relationships and dependencies between different components in the application. This will help ensure that the application is deployed and configured correctly.
- Inputs and Outputs: Define inputs and outputs for your templates, which will enable the templates to be customized for different environments and use cases.
- Policies: Define policies that describe the desired behavior of the application, such as scaling policies, availability policies, and security policies.
- Workflows: Define workflows that describe the sequence of steps required to deploy and configure the application. Workflows can include tasks such as provisioning resources, configuring applications, and testing the deployment.
- Artifacts: Include any artifacts that are required for the application, such as configuration files, scripts, and binaries.
- Metadata: Include metadata that describes the application, such as its name, version, and author.
By including these elements in your TOSCA templates, you can ensure that your templates are easy to understand, maintain, and customize.
