The concept of a k8s
1.1 k8s
k8s is a lightweight platform for managing containerized applications and services. Automatic deployment, expansion and contraction of applications can be performed through k8s.
1.2 k8s core part
1.prod: the smallest deployment unit ; a collection of containers; shared network; life cycle is short;
2. controller: ensure the expected number of pod copies ; stateless application deployment; stateful application deployment; ensure that all nodes run the same pod, one task and scheduled task.
3.service: define a set of pid access rules.
1.3 Components of the k8s cluster
Two delivery cases
2.1 Overview of the delivery process
1. Overall process
2. Detailed process
2.2 Step 1: Make a jar package
2.3 Step 2: Make a mirror image
2.4 Step 3: Push the image to the image container
2.5 Step 4: Deploy the image, expose the port application
