💡 Learning Ansible for Abhishek Veeramalla's 14 Days Series I have made some Notes that I feel would be helpful for anyone starting with Ansible.

And what were the problems that system administrators used to face without the configuration management tool that is Ansible? Why Ansible is better than Puppet and Chef? Ansible V/S SHELL Scripting V/S Python ⌛Day 2: Ansible Passwordless Authentication | Inventory | Adhoc commands 2 Ways of Authentication: a) Password b) SSH Keys (I am facing some errors when I run the commands so I will re-visit the lecture again) ⌛Day 3: Ansible Playbook (YAML & JSON) Understanding YAML - There are built-in and custom modules. - The first task that every ansible play will run is 'Gathering Facts'. It checks and connects to the EC2 instance and gathers information. ⌛Day 4: Ansible Roles - Huge Ansible files would be a mess to read and that's where Roles come in handy. - Divide the Ansible playbook into different folders such as variables, handlers, and tasks. - This enhances readability and modularity and for sharing across different teams. ⌛Day 5: Ansible Galaxy (Builds entire folder structure) P.S. I tried making the pdf easy to read but if it's not please let me know and I will create graphical content on Canva. Also, I will update you about the practicals that I will do while learning Ansible and compile a list of errors that I encountered and the possible solutions to resolve them. #ansible #configuration #devops #cloud #devopstools #terraform #linux #commands Thanks to Abhishek Veeramalla for his insightful videos on DevOps and Cloud.

Learn terraform from basics to advanced in the devops course by Praveen Singampalli starting from tomorrow https://lnkd.in/gsryE-Bj Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. It creates and manages resources on cloud platforms and other services through their application programming interfaces (APIs). Providers enable Terraform to work with virtually any platform or service with an accessible API. The core Terraform workflow consists of three stages: Write: You define resources, which may be across multiple cloud providers and services. For example, you might create a configuration to deploy an application on virtual machines in a Virtual Private Cloud (VPC) network with security groups and a load balancer. Plan: Terraform creates an execution plan describing the infrastructure it will create, update, or destroy based on the existing infrastructure and your configuration. Apply: On approval, Terraform performs the proposed operations in the correct order, respecting any resource dependencies. For example, if you update the properties of a VPC and change the number of virtual machines in that VPC, Terraform will recreate the VPC before scaling the virtual machines.

𝐒𝐭𝐚𝐭𝐞𝐟𝐮𝐥𝐒𝐞𝐭 𝐢𝐧 𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬 A StatefulSet in Kubernetes helps manage stateful applications that need stable identifiers and persistent storage. Here’s a simple breakdown: 𝐊𝐞𝐲 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬: -  Stable, Unique Network Identifiers: Each Pod gets a stable hostname based on its index, making it easy for Pods to communicate with each other.    - Ordered Deployment and Scaling: Pods are created and scaled one at a time in a specific order, ensuring dependencies are managed properly.    - Persistent Storage: Each Pod can have a PersistentVolumeClaim (PVC), allowing data to persist even if the Pod restarts or moves.    - Rolling Updates and Graceful Scaling: Supports updates and scaling without downtime, replacing each Pod one at a time.    - Headless Service: Uses a headless service for network identity, providing DNS resolution for each Pod without load balancing traffic. 𝐂𝐨𝐦𝐦𝐨𝐧 𝐔𝐬𝐞𝐬 𝐟𝐨𝐫 𝐒𝐭𝐚𝐭𝐞𝐟𝐮𝐥𝐒𝐞𝐭𝐬: - Databases (e.g., MySQL, PostgreSQL) - Messaging queues (e.g., Kafka, RabbitMQ) - Other stateful applications needing stable identities and data persistence Follow Omkar Srivastava for more content.
