Cài đặt và sử dụng:

Cài đặt localstack:

YAML
# docker-compose.yml

version: "3.2"
services:
  localstack:
    image: localstack/localstack:latest
    container_name: localstack_demo
    ports:
      # - "127.0.0.1:4566:4566" # LocalStack Gateway
      - "127.0.0.1:4510-4559:4510-4559" # external services port range
      - "0.0.0.0:4566:4566"
    environment:
      - SERVICES=s3
      - DEBUG=1
      - DATA_DIR=/tmp/localstack/data
    volumes:
      - "./.localstack:/var/lib/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

Start localstack:

Zsh
docker-compose up -d

Tạo profile cho Localstack:

Zsh
aws configure --profile localstack
 
AWS Access Key ID [****************demo]: dummy
AWS Secret Access Key [****************demo]: dummy
Default region name [ap-northeast-1]: ap-northeast-1
Default output format [json]: json

Or

Zsh
vi ~/.aws/config
VimL
[profile localstack]
output = json
region = ap-northeast-1
Zsh
vi ~/.aws/credentials
VimL
[localstack]
aws_access_key_id = dummy
aws_secret_access_key = dummy

Tạo S3 trong Localstack:

Zsh
aws --endpoint-url=http://localhost:4566 --profile localstack s3api create-bucket --bucket test-bucket --create-bucket-configuration LocationConstraint=ap-northeast-1

# Kết quả:
{
    "Location": "http://test-bucket.s3.localhost.localstack.cloud:4566/"
}
Zsh
aws s3 ls --endpoint-url=http://localhost:4566 --profile localstack

# Kết quả:
2023-11-15 10:24:40 test-bucket
YAML
# .env

# Cả 2 endpoint đều hoạt động với Localstack ở local.
#S3_ENDPOINT='http://localhost:4566'
S3_ENDPOINT='http://test-bucket.s3.localhost.localstack.cloud:4566/'
S3_AWS_ACCESS_KEY_ID='dummy'
S3_AWS_SECRET_KEY='dummy'
S3_AWS_BUCKET_NAME='test-bucket'

Tạo Dynamodb trong Localstack:

YAML
version: "3.2"
services:
  localstack:
    image: localstack/localstack:latest
    container_name: localstack_demo
    ports:
      # - "127.0.0.1:4566:4566" # LocalStack Gateway
      - "127.0.0.1:4510-4559:4510-4559" # external services port range
      - "0.0.0.0:4566:4566"
    environment:
      - SERVICES=dynamodb
      - DEBUG=1
      - DATA_DIR=/tmp/localstack/data
    volumes:
      - "./.localstack:/var/lib/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"
Zsh
aws dynamodb create-table \
    --table-name test \
    --key-schema AttributeName=id,KeyType=HASH \
    --attribute-definitions AttributeName=id,AttributeType=S \
    --billing-mode PAY_PER_REQUEST \
    --region ap-northeast-1 \
    --endpoint-url=http://localhost:4566 \
    --profile localstack

# Kết quả:
{
    "TableDescription": {
        "AttributeDefinitions": [
            {
                "AttributeName": "id",
                "AttributeType": "S"
            }
        ],
        "TableName": "test",
        "KeySchema": [
            {
                "AttributeName": "id",
                "KeyType": "HASH"
            }
        ],
        "TableStatus": "ACTIVE",
        "CreationDateTime": "2023-11-15T11:29:05.597000+07:00",
        "ProvisionedThroughput": {
            "LastIncreaseDateTime": "1970-01-01T07:00:00+07:00",
            "LastDecreaseDateTime": "1970-01-01T07:00:00+07:00",
            "NumberOfDecreasesToday": 0,
            "ReadCapacityUnits": 0,
            "WriteCapacityUnits": 0
        },
        "TableSizeBytes": 0,
        "ItemCount": 0,
        "TableArn": "arn:aws:dynamodb:ap-northeast-1:000000000000:table/test",
        "TableId": "fb25d41f-0563-4be9-8b21-75bc3b7006b9",
        "BillingModeSummary": {
            "BillingMode": "PAY_PER_REQUEST",
            "LastUpdateToPayPerRequestDateTime": "2023-11-15T11:29:05.597000+07:00"
        }
    }
}
Bạn muốn sử dụng dịch vụ nào của AWS thì thêm dịch vụ đấy vào SERVICES trong file docker-compose.yml.
