AGILE CRASH COURSE UDEMY

Agile Principles

  1. Customer satisfaction by early and continuous delivery of useful software.
  2. Welcome changing requirements, even late in development.
  3. Working software is delivered frequently (weeks rather than months).
  4. Close, daily cooperation between business people and developers.
  5. Projects are built around motivated individuals, who should be trusted.
  6. Face-to-face conversation is the best form of communication (co-location).
  7. Working software is the principal measure of progress.
  8. Sustainable development, able to maintain a constant pace.
  9. Continuous attention to technical excellence and good design.
  10. Simplicity- only build what is really essential.
  11. Self-organizing teams.
  12. Regular adaptation to changing circumstance.

CI/CD Pipeline and Devops Introduction

OLD SDLC

{Development Team}

Developer 1 –> Developer 2 –> > Build & Integration Team -> Ensures Code Compiles -> Package Developer 3 –>

Operations Team

Package is given with instructions to operations team

The Operations team deploys the app and then testers test. Image Description

#Cons

  1. Integrating different modules is error prone task as integration team communicates with developers to integrate each developers modules into a single unite.
  2. Defects are detected late.
  3. Any intermediate code merge can cause issues.
  4. If a developer brings up functional defect, it will stay there until the end of iteration which may take too long.
  5. Long Feedback cycle
  6. Long Iteration Image Description

Continuous Integration

Continuous integration is a development practice that requires developers to integrate code into a shared repo several times a day.

Custom Spring Boot Banners

Spring Boot Banners

In this endpoint of internet, we’ll explore how to create a custom banner in a Spring Boot application.

Image Description

Overview

When a Spring Boot application starts, it prints a banner, a visual representation, or text (often with ASCII graphics or branding information). The banner is a way to provide a more engaging and informative startup experience for developers and users such as the application name, version, or any other relevant data.

Docker Full Notes

What is Docker?

  • Docker is an open platform for developing, shipping and running applications.
  • Docker is a platform which packages an application and all its dependencies together in the form of containers.

What problem does Docker solve?

The main problem it solves is dependency management. Image Description


Docker Architecture

Image Description


Some Terms to Understand

  1. Docker Daemon: Daemon is a program which runs on our computer and manages docker containers.
  2. Docker file: It is a text document which contains all the commands that a user can call on the command line to assemble an image.
  3. Images: Template to create docker container.
  4. Container: Running instance of docker image.Containers hold entire package to run application.

Basic Commands for Docker

  • Check the version
docker -v
  • pull image
docker pull <image-name>
  • check all the images
docker images
  • search images
docker search <image-name>
  • container creation
docker run <image-name>
  • list all the running containers
docker ps
  • list all the running + stopped containers
docker ps -a
  • run container in background(detached mode) + change the name of container.
docker run --name <custom-name> -d <image-name/image-id>
  • run container in -it {interactive-mode}, your container will run continuously
docker run --name <custom-name> -it -d <image-id/name> 
  • to execute the command inside your container
docker exec -it <container-id> command{python3/bash/java/cpp} 
  • get all the information about the container
docker inspect <container-id>
  • stop the running container
docker stop <containerName>
  • remove image
docker rm <image-name>
  • to restart the running container
docker restart <container-id>

My-SQL Image Commands

  • get the image
docker install mysql
  • run the mysql container
docker run --name <custome-mysql-name> -e MYSQL_ROOT_PASSWORD=<give-a-pass> -d mysql
  • use commands inside mysql container
docker exec -it <custom-sql-name> <command-type>
