Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

A Practical Guide to Kubernetes

# Allocating Insufficient Resources


Let's look at a slightly modified version of the `go-demo-2` definition as `go-demo-2-insuf-mem.yml`. When compared with the previous definition, the difference is only in `resources` of the `db` container in the `go-demo-2-db` Deployment.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: go-demo-2-db
spec:
  ...
  template:
    ...
    spec:
      containers:
      - name: db
        image: mongo:3.3
        resources:
          limits:
            memory: 20Mi
            cpu: 0.5
          requests:
            memory: 10Mi
            cpu: 0.3

The memory limit is set to `20Mi` and the request to `10Mi`. Since we already know from Metrics Server's data that MongoDB requires around `35Mi`, memory resources are much lower than the actual usage this time.
