Hands-On Microservices with Kubernetes

Packaging and deploying microservices

When you employ a microservice-based architecture, you'll have lots of microservices. Those microservices, in general, may be developed independently, and deployed independently. The packaging mechanism is simply containers. Every microservice you develop will have a Dockerfile. The resulting image represents the deployment unit for that microservice. In Kubernetes, your microservice image will run inside a pod (possibly alongside other containers). But an isolated pod, running on a node, is not very resilient. The kubelet on the node will restart the pod's container if it crashes, but if something happens to the node itself, the pod is gone. Kubernetes has abstractions and resources that build on the ...
