Part I. Foundational Patterns
Foundational patterns describe a number of fundamental principles that containerized applications must comply with in order to become good cloud-native citizens. Adhering to these principles will help ensure your applications are suitable for automation in cloud-native platforms such as Kubernetes.
The patterns described in the following chapters represent the foundational building blocks of distributed container-based Kubernetes-native applications:
-
Chapter 2, Predictable Demands, explains why every container should declare its resource profile and stay confined to the indicated resource requirements.
-
Chapter 3, Declarative Deployment, shows the different application deployment strategies that can be performed in a declarative way.
-
Chapter 4, Health Probe, dictates that every container should implement specific APIs to help the platform observe and manage the application in the healthiest way possible.
-
Chapter 5, Managed Lifecycle, describes why a container should have a way to read the events coming from the platform and conform by reacting to those events.
-
Chapter 6, Automated Placement, introduces a pattern for distributing containers in a Kubernetes multinode cluster.
