A Kubernetes manifest is a YAML configuration file that declares the desired state of Kubernetes resources. Kubernetes handles the steps needed to reach that declared result. section 1.1 section 8.0
A manifest can describe:
- The container image and the resources needed to run it. section 8.3
- A Pod or other Kubernetes resources that support container operation. section 8.3
- A repeatable deployment that can be reused across applications, servers, and hosts. section 1.1
Declarative deployment statements
A manifest expresses the result wanted rather than the procedure: use a Python application, use Python 3.10, run it on ports 80 and 443, allow internet traffic, and use example.com. section 1.1
