How to use MinIO with the same function as S3 Use docker-compose


I tried to make it usable with docker for development even in the situation where AWS services can not be used due to various circumstances (contract problems, budget, etc.). The title is MinIO, but DynamoDB and MySQL are also available.

Advance preparation


version: '3.7'
    build: ./dynamodb
      - dynamodb_data:/home/dynamodblocal/data
      - 8000:8000
    command: -jar DynamoDBLocal.jar -dbPath ./data
    image: mysql:5.7
    command: mysqld --character-set-server=utf8 --collation-server=utf8_unicode_ci
      - db_data:/var/lib/mysql
    restart: always
      MYSQL_ROOT_PASSWORD: 'password'
      - 3306:3306
    image: minio/minio:RELEASE.2020-08-27T05-16-20Z
      - data1-1:/data1
      - data1-2:/data2
      - "9000:9000"
      MINIO_ACCESS_KEY: minio
      MINIO_SECRET_KEY: minio123
    command: server data1
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3
  db_data: {}
FROM amazon/dynamodb-local

WORKDIR /home/dynamodblocal

# UID=1000 → DynamoDB Local execution user
RUN mkdir data && chown -R 1000 data
minio1_1          | Endpoint:
minio1_1          |
minio1_1          | Browser Access:
minio1_1          |

Implementation of S3 function

import boto3
import os
from datetime import datetime

endpoint_url = os.getenv('S3_ENDPOINT', '')
aws_access_key_id = os.getenv('S3_ACCESS_KEY_ID', 'minio')
aws_secret_access_key_id = os.getenv('S3_SECRET_ACCESS_KEY_ID', 'minio123')

s3 = boto3.resource(
