https://github.com/idenrai/templates/tree/main/dynamodb_local

詳細

準備

Docker

Docker Desktop インストール

https://docs.docker.com/desktop/install/mac-install/

AWS

AWS-CLI

https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html

boto3

pip install boto3

https://boto3.amazonaws.com/v1/documentation/api/latest/guide/quickstart.html

Configure

円滑な利用のため、AWS Credentials 設定が必要

aws configure

以下のように設定

$ aws configure
AWS Access Key ID [None]: dummy
AWS Secret Access Key [None]: dummy
Default region name [None]: ap-northeast-1
Default output format [None]: json

手動設定の場合は以下になる

touch ~/.aws/credentials
vi ~/.aws/credentials

[default]
aws_access_key_id = dummy
aws_secret_access_key = dummy

touch ~/.aws/config
vi ~/.aws/config

[default]
region = ap-northeast-1
output = json

Code

以下の２つを利用

amazon/dynamodb-local
aaronshaf/dynamodb-admin

docker-compose.yml

version: "3.8"
services:
  dynamodb-local:
    command: "-jar DynamoDBLocal.jar -sharedDb -dbPath ./data"
    image: "amazon/dynamodb-local:latest"
    container_name: dynamodb-local
    ports:
      - "8000:8000"
    volumes:
      - "./docker/dynamodb:/home/dynamodblocal/data"
    working_dir: /home/dynamodblocal

  dynamodb-admin:
    container_name: dynamodb-admin
    image: aaronshaf/dynamodb-admin:latest
    environment:
      DYNAMO_ENDPOINT: dynamodb-local:8000
    ports:
      - "8001:8001"
    depends_on:
      - dynamodb-local

Run

docker-compose up

Test

aws dynamodb list-tables --endpoint-url http://localhost:8000

以下のように出力されたら OK

$ aws dynamodb list-tables --endpoint-url http://localhost:8000
{
    "TableNames": []
}

GUI

8000 で DynamoDB を, 8001 で GUI を起動するので、GUI からも確認可能

http://localhost:8001/
