Overview

This devops bootcamp is the first among several series (coming soon!) to start -or advance- your career as DevOPs or SRE (Site Reliability Engineer).

In this course, you will learn about container technology (docker) and container orchestration (kubernetes). Those are a-must-have knowledge for DevOps engineeer, as docker and kubernetes are popular technology and well sought by many companies. You will also learn about GitOps using ArgoCD, and how to use Istio Service Mesh with Envoy proxy to ease the application management.

What We Will Learn

We will learn how to manage application written on microservice architecture. You don't need to know any programming language to works with this course. In fact, this course is not about programming language, and mostly we will works with text files, terminal, or even graphical user interface.

Learn how to reach infrastructure agility, and easier maintenance compared to traditional infrastrucutre (virtual machine, bare metal). With the help of kubernetes, along with other tools that integrates well, maintaining reliable infrasturcture become a skill that everybody can learn (by using this course, for example).

But kubernetes and docker is not the only technology required for DevOps engineer journey. In this course, we will learn real-life infrastructure architecture that leverages several technologies, integrated to kubernetes. They are:

• Nginx : very popular reverse proxy, http load balancer, which is used as traffic gateway, or kubernetes ingress controller

• Sealed secret : secure your username, password, and any other "secret" things on kubernetes. Update and share them safely, since the kubernetes will "seal" them and encrypt them in secure way

• Grafana, Prometheus : for kubernetes & infrastructure data gathering, analytics, and visualization

• Helm : a package manager for kubernetes. Think of zip archive, but kubernetes-style, that can customized

• Chartmuseum : a repository for helm

• ArgoCD : learn GitOps, a subset of DevOps that focusing on automatic infrastructure based on git repository. Works well since most software engineering team will already familiar with git, so they can also leverage the kubernetes power without knowing the kubernetes itself. Collaborate together, and achieve automated application deployment through GitOps with ArgoCD

• Istio & Envoy Proxy : One of the most important item to works with kubernetes. Manage, secure, and monitor your traffic. Add application functionalities without even writing single line of code

• Kiali : Istio user interface to visualize your traffic that runs on kubernetes cluster,and manage them!

• Jaeger : distributed tracing to know how your microservices performs, which node that has problem

• Lens : hate to see the black screen on terminal? Then use this tools to navigate your kubernetes cluster

  
  

Pre-requisites

• laptop with at least 8 GB memory free (so you need at least 16 GB memory)

• or you can use any laptop, since we will learn to use Google Kubernetes Engine (it might has limited free quota if you are new user, but it depends on google)
