Step 1: First of all you have to select aws code build service.

After that click on create build project

After that in source provider select Github and click on connect to github

Then click on switch to editor

COPY

COPY

version: 0.2

#env:
  #parameter-store:
     # key: "value"
     # key: "value"

phases:
  install:
    #If you use the Ubuntu standard image 2.0 or later, you must specify runtime-versions.
    #If you specify runtime-versions and use an image other than Ubuntu standard image 2.0, the build fails.
    runtime-versions:
       python: 3.11
    pre_build:
    commands:
      - pip install -r day-14/simple-python-app/requirements.txt
      # - command
  build:
    commands:
       - cd day-14/simple-python-app
       - echo "Building Docker Image"
       - docker build -t "<>"
       - docker push <>
  post_build:
    commands:
       - echo "Build is successful"

Then click on build project

Step 2 : Then search for systems manager

Then go to the parameter store

Step 3 : Then go to the build space add this code

COPY

COPY

version: 0.2

env:
  parameter-store:
    DOCKER_REGISTRY_USERNAME: /myapp/docker-credentials/username
    DOCKER_REGISTRY_PASSWORD: /myapp/docker-credentials/password
    DOCKER_REGISTRY_URL: /myapp/docker-registry/url
phases:
  install:
    runtime-versions:
      python: 3.11
  pre_build:
    commands:
      - echo "Installing dependencies..."
      - pip install -r day-14/simple-python-app/requirements.txt
  build:
    commands:
      - echo "Running tests..."
      - cd day-14/simple-python-app/
      - echo "Building Docker image..."
      - echo "$DOCKER_REGISTRY_PASSWORD" | docker login -u "$DOCKER_REGISTRY_USERNAME" --password-stdin "$DOCKER_REGISTRY_URL"
      - docker build -t "$DOCKER_REGISTRY_URL/$DOCKER_REGISTRY_USERNAME/simple-python-flask-app:latest" .
      - docker push "$DOCKER_REGISTRY_URL/$DOCKER_REGISTRY_USERNAME/simple-python-flask-app:latest"
  post_build:
    commands:
      - echo "Build completed successfully!"
artifacts:
  files:
    - '**/*'
  base-directory: ../simple-python-app

Step 4 : Then click on build code

Step 5: Then go to the code pipeline

Then click on create pipeline

Then click on connect to github

Skip the deploy stage

After that click on create pipeline

Step 6: Then search for aws code deploy service

Then click on code deploy

Then click on create application

Then create aws ec2 instance

Then you need to create tags

Then you need to install code deploy agent on ec2 instance you can refer this link

docs.aws.amazon.com/codedeploy/latest/userg..

Then you need to create IAM Role

And after that you need to grand permission to code deploy

After that assign this role to the ec2 instance

Then go to the code deploy and create deployment group

Then click on create deployment group

Then you need to click on create deployment

Then click on create deployment

Then go to the code pipeline

Then click on edit

Then click on add stage

Then click on add action group
