version: 0.2

env:
  shell: bash

phases:
  pre_build:
    commands:
      - export CODE_DIR=`pwd`
      - export CONTAINER_DIR=/code
      - current_requirements_checksum="$(md5sum package.json yarn.lock Dockerfile)"
      - previous_requirements_checksum=$(cat /code/requirements_checksum.txt)
      - echo "$current_requirements_checksum"
      - echo "$previous_requirements_checksum"
      - export ANDROID_HOME="$HOME/Android/Sdk"
      - echo $SERVICE_ACCOUNT_CREDENTIALS_ENCODED | base64 -di >> $CODE_DIR/apps/crm-agent-mobile-app/android/app/service-account-credentials.json
      - cp -r  $CODE_DIR/. $CONTAINER_DIR
      - |
        if [[ "$current_requirements_checksum" = "$previous_requirements_checksum" ]];
          then
            echo "Checksum matched";
          else
            echo "Checksum didn't match";
            exit -1;
        fi
  build:
    commands:
      - CI_BUILD_NUMBER=$CODEBUILD_BUILD_NUMBER
      - cd $CONTAINER_DIR
      - echo "NX_BACKEND_REST_URL=$NX_BACKEND_REST_URL" >> apps/crm-agent-mobile-app/.env
      - echo "NX_BACKEND_GRAPHQL_URL=$NX_BACKEND_GRAPHQL_URL" >> apps/crm-agent-mobile-app/.env
      - nohup npx nx run crm-agent-mobile-app:start-cicd:prod &
      - cd apps/crm-agent-mobile-app/android
      - sleep 15
      # Build and Distribute the App
      - ./gradlew assembleProdRelease appDistributionUploadProdRelease
      - export APP_PATH_IN_S3=releases/$CODEBUILD_SOURCE_VERSION/app-prod-release.apk
      - aws s3 cp $CODE_DIR/apps/crm-agent-mobile-app/android/app/build/outputs/apk/prod/release/app-prod-release.apk s3://$BUCKET_NAME/$APP_PATH_IN_S3
      # Notify in iBCom with Apk URL
      - python3 $CODE_DIR/mobile_app_post_build_script.py
      - echo "Deployed $CI_BUILD_NUMBER"

• Then save and approve the action to update Project in AWS.

version: 0.2

env:
  shell: bash

phases:
  install:
    runtime-versions:
      python: 3.7

  pre_build:
    commands:
      - export AWS_ACCOUNT_ID=$(echo $CODEBUILD_BUILD_ARN | cut -d ":" -f 5)
      - aws ecr get-login-password --region ${AWS_REGION} | docker login --username AWS --password-stdin ${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com
      - docker pull ${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com/${DOCKER_IMAGE_NAME_WITH_TAG} || true
      - echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

  build:
    commands:
      - docker build --cache-from ${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com/${DOCKER_IMAGE_NAME_WITH_TAG} -t ${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com/${DOCKER_IMAGE_NAME_WITH_TAG} . --build-arg JFROG_NPM_EMAIL=$JFROG_NPM_EMAIL --build-arg JFROG_NPM_AUTH=$JFROG_NPM_AUTH --build-arg JFROG_NPM_USERNAME=$JFROG_NPM_USERNAME --build-arg JFROG_NPM_PASSWORD=$JFROG_NPM_PASSWORD
      - docker push ${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com/${DOCKER_IMAGE_NAME_WITH_TAG}
      - echo "Deployed $CI_BUILD_NUMBER"

Build the Base Image

In DevOps Console navigate to the Actions and approve the task with BUILD_DOCKER_IMAGE_AND_PUSH action_type

Then trigger the main build, it will use the base image built in the above build and run the commands on top of it.
