A curated list of AWS resources to prepare for the AWS Certifications
A curated list of awesome AWS resources you need to prepare for the all 5 AWS Certifications. This gist will include: open source repos, blogs & blogposts, ebooks, PDF, whitepapers, video courses, free lecture, slides, sample test and many other resources.
| Introduction | |
| Hands-on Ansible, where we're going to learn and get our hands dirty about system provisioning, change management, and automation using the open source software, Ansible. Throughout this course we'll be showing you the concepts and fundamentals of the software, along with real world examples and exercises on doing many server-related tasks. My name is Aaron Paxson, and in this module we'll be introducing Ansible, what it can do, and why you'd want to use it. | |
| What Is Ansible? | |
| So really what exactly is Ansible? Well perhaps you heard somebody talking about it or maybe you read about it online. Well the name actually came from an old sci-fi writer back in the '60s which denoted a fictitious device that is supposed to communicate over interstellar distances in like real time, and after that definition, well, you may have thought of Ender Wiggin from the movie Ender's Game. In this movie, Ender actually uses an Ansible to communicate to thousands of ships galaxies away in real time, and incidentally, |
| Pillars of automating infrastructure Deployment (resources): | |
| 1.Provisioning resources | |
| 2.Planning Updates | |
| 3.Using Source Control | |
| 4.Reusing templates | |
| Variables and Environment | |
| Dev, QA, Production | |
| Variables and multi states | |
| Store secrets in safe place |
| Goals: | |
| Build | |
| Least privileged access for pipeline and all supporting components | |
| Repo optimization | |
| KMS intergration | |
| Operational readiness for supporting AWS services for pipeline | |
| Test | |
| Well defined patterns,tooling and best practices and documentation for testing of applications and integration with pipeline | |
| All test and testing frameworks for applications supported and integrated with ADOPT (Unit, Integration and Smoke) |

| Install SonarQube plug-in on Jenkins build server no matter in local(or)AWS, | |
| Application team needs to have access to SonarQube application dashboard. | |
| From CI/CD perspective, we installed and configured Sonar plug-in in Jenkins build server by passing below parameters on properties file to run code analysis for every build, | |
| A.EC2 Instance SETUP: | |
| Launch EC2 Instances | |
| --IAM Role | |
| ecsInstanceRole | |
| --- Security group | |
| Allow SSH,HTTP and Lb | |
| -- User data | |
| . /etc/ecs/ecs.config | |
| -- Key pair | |
| SSH into instance |
| Command to retrieve password after docker installation : | |
| The password was saved to /var/jenkins_home/secrets/initialAdminPassword. | |
| You can use | |
| CMD: docker exec <container> cat /var/jenkins_home/secrets/initialAdminPassword | |
| where <container> is your container id or name. | |

| ## Understanding Ansible | |
| Ansible is a powerful, simple, and easy to use tool for managing computers. It is most often used to update programs and configuration on dozens of servers at once, but the abstractions are the same whether you're managing one computer or a hundred. | |
| Ansible can even do "fun" things like change the desktop photo or backup personal files to the cloud. It can take a while to learn how to use Ansible because it has an extensive terminology, but once you understand the why and the how of Ansible, its power is readily apparent. | |
| Ansible's power comes from its simplicity. Under the hood, Ansible is just a domain specific language (DSL) for a task runner for a secure shell (ssh). You write ansible yaml (.yml) files which describe the tasks which must run to turn plain old / virtualized / cloud computers into production ready server-beasts. These tasks, in turn, have easy to understand names like "copy", "file", "command", "ping", or "lineinfile". Each of these turns into shell comma |
