Week X — Cleanup

Preparation

  • Create static-build-frontend script for deploying static web resources

  • Run static-build-frontend script and Fix main frontend issues fix#1 and fix#2

  • Zip all static frontend content to deliver to S3

  • Create or install Gemfile for aws_s3_website_sync and dotenv

  • Create rake file for sync and run sync

  • Before run sync script don't forget run npm install and npm build in frontend dir

Rake file for sync sync-static-s3 file:

#!/usr/bin/env ruby
puts("==== Installing <gem install aws_s3_website_sync> ====")
require 'bundler/inline'
require 'nokogiri'

gemfile do
  source 'https://rubygems.org'
  gem 'aws_s3_website_sync', require: true
  gem 'dotenv', require: true 
end

require 'aws_s3_website_sync'
require 'dotenv'

env_path = "/workspace/aws-bootcamp-cruddur-2023/erb/sync.env"
Dotenv.load(env_path)

puts "== configuration"
puts "aws_default_region:   #{ENV["AWS_DEFAULT_REGION"]}"
puts "s3_bucket:            #{ENV["SYNC_S3_BUCKET"]}"
puts "distribution_id:      #{ENV["SYNC_CLOUDFRONT_DISTRUBTION_ID"]}"
puts "build_dir:            #{ENV["SYNC_BUILD_DIR"]}"

changeset_path = ENV["SYNC_OUTPUT_CHANGESET_PATH"]
changeset_path = changeset_path.sub(".json","-#{Time.now.to_i}.json")

puts "output_changset_path: #{changeset_path}"
puts "auto_approve:         #{ENV["SYNC_AUTO_APPROVE"]}"

puts("==== Syncing static content with AWS S3 Bucket ====")

puts "sync =="
AwsS3WebsiteSync::Runner.run(
  aws_access_key_id:     ENV["AWS_ACCESS_KEY_ID"],
  aws_secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],

Reconnect Database and Post Confirmation Lambda

the main issues was in Lambda Post Confirmation function:

  • First Check code

  • Next check CONNECTION_URL and update it

  • After run schema-load, migrate and seed scripts for Loading data into rds

  • Delete your old user from Cognito and join one more time to omgchat.xyz

  • Check your connection to prod postresql, before that you'll need update GITPOD_IP, DB_SG_ID and DB_SG_RULE_ID and run update-sg-rule to give access to RDS

You should have access

psql $CONNECTION_URL_PROD
  • Check your new user from Database and run command bellow

You should see something like that, <cognito_user_id> shouldn't be empty

omgchat=> select * from users;
                 uuid                 |  display_name   | handle  |          email           |           cognito_user_id            |         created_at

Refactoring Ddb

  • Add ENV VAR DDB_MESSAGE_TABLE="OmgDdb-DynamoDBTable-KWLL3BZ0AUVY" into backend-flask.env

  • Change table name ddb.py 4 line

table_name = os.getenv("DDB_MESSAGE_TABLE")
  • Add ENV VAR to the template.yaml
            - Name: 'DDB_MESSAGE_TABLE'
              Value: !Ref DDBMessageTable
  • Create AWS CFN for MachineUser DynamoDB
