AWS Mongolian Community-д тавтай морилно уу!

Доорх ойлголтуудыг нэгтгэж Text-to-Speech simple project хийх болно.

AWS Lambda
Python programming language (AWS boto library)
AWS S3 static web site hosting
AWS API Gateway
AWS Dynamo DB
AWS Polly service

1. AWS account үүсгэх

2. Region сонгох

2019 оны I сарын байдлаар AWS 16 ширхэг public region-той байна. Өнөөдөр hacknight-р бид Tokyo region дээр ажиллах болно.

3. Create DynamoDB table

Table name: texts primary key: id (String) - Lowercase!

4. Create 2 buckets

Bucket name must be globally unique! Өөрсдийн нэрээр нэрлэнэ үү.

Bucket #1: mnhacknight-web (web ажиллах bucket, domain холбох бол www.jiguur001.tk)
Bucket #2: mnhacknight-mp3 (mp3 file хадгалах bucket)

Make them public

5. Create a role for Lambda

5.1. Create a policy

Name: LambdaPolicyForHacknightV1 Type: JSON

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "polly:SynthesizeSpeech",
        "dynamodb:Query",
        "dynamodb:Scan",
        "dynamodb:PutItem",
        "dynamodb:UpdateItem",
        "sns:Publish",
        "s3:PutObject",
        "s3:PutObjectAcl",
        "s3:GetBucketLocation",
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents"
      ],
      "Resource": [
        "*"
      ]
    }
  ]
}

5.2. Create a Role using policy

Name: LambdaRoleForHacknightV1
Choose existing role: LambdaPolicyForHacknightV1
Service: Lambda

6. Create Lambda functions from scratch

6.1. HacknightV1_NewText (Name)

Зориулалт

Орж ирсэн текстийг DynamoDB лүү хадгална
DynamoDB-с түүнийгээ select хийж Polly service ашиглан mp3 болгоно
mp3 болгосон file-г S3 bucket дотор хадгална

Python 2.7
Choose an existing role: LambdaRoleForHacknightV1

Use the file name: newtext.py

Add environment variables
DB_TABLE_NAME: texts
BUCKET_NAME: mnhacknight-mp3 (Section 4 дээр өгсөн нэр)
Add description
Set time-out to 5 mins
Test Hello World

{
    "voice": "Joanna",
    "text": "Hello Amazon Web Services Mongolian Community!"
}

Check DynamoDB table

6.2. HacknightV1_GetText (Name)

Зориулалт: DynamoDB-с утгуудыг query-дэнэ

Python 2.7
Choose an existing role: LambdaRoleForHacknightV1

Use the file name: gettext.py

Add environment variables DB_TABLE_NAME: texts
Add function description
Set time-ut to 5 secs
Test Hello World

{
 	"postId": "*"
}

7. Create API Gateway

Name: HacknightV1API

Add GET Method Integration type: Lambda function
Target: HacknightV1_GetText
Get request-ийн URL-с параметер авахын тулд Mapping хийж өгөх ёстой
Integration request -> Body Mapping Templates -> When there are no templates defined -> application/json гэж бичиж оруулна

{
    "postId": "$input.params('postId')"
}

Add POST Method Integration type: Lambda function Target: HacknightV1_NewText
Click Action -> Enable CORS -> Hit Enable CORS
Deploy API Deployment stage: [new stage] other fields all prod
Click stage -> prod -> Invoke URL copy-дож авна

8. Replace API URL

scripts.js хамгийн дээр хуулна

9. Make static website hosting

Go to S3 and add 2 following files.

echo '<h1>Hello world</h1>' > index.html

index.html error.html

Add policy:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "PublicReadGetObject",
      "Effect": "Allow",
      "Principal": "*",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::REPLACE_BUCKET_NAME_HERE/*"
    }
  ]
}

Make public access on Access control list

Then try deleting index.html

10. Upload web files to our bucket

index.html scripts.js styles.css

Select all show dummy data, then delete it from DynamoDB

Extra S3, SSL, Domain name

bucket name must be same as domain name /N.Virginia/
Freenom - Request new domain, wait ns /mnhacknight.ml/
Route53 - create a hosted zone /mnhacknight.ml/
Fill namespaces in Freenom
Create cloudfront distribution with s3 bucket /index.html, ~30min/
request certificate. mnhacknight.ml, validate with DNS, Create record set with Route53
Edit distribution with SSL certificate
Invalidate
edit Route53 a record route to Cloudfront
