S3 バケットを作成する
% export AWS_PROFILE=localstack
% aws s3 mb s3://test-bucket --endpoint-url=http://localhost:4566
make_bucket: test-bucket
% aws s3 ls --endpoint-url=http://localhost:4566
2022-05-26 23:24:03 test-bucket
endpoint 指定が面倒なので awslocal をインストール
% pip3 install awscli-local
% awslocal s3 ls

DynamoDB のテーブルを作る
% awslocal dynamodb create-table \
--table-name vote \
--attribute-definitions \
AttributeName=user_id,AttributeType=S \
AttributeName=dt,AttributeType=S \
--key-schema AttributeName=user_id,KeyType=HASH AttributeName=dt,KeyType=RANGE \
--billing-mode PAY_PER_REQUEST
データの挿入
% awslocal dynamodb put-item \
--table-name vote \
--item '{ "product_id": { "N": "3" }, "dt": { "S": "20220512" }, "user_id": { "S": "u123" } }'
% awslocal dynamodb put-item \
--table-name vote \
--item '{ "product_id": { "N": "17" }, "dt": { "S": "20220512" }, "user_id": { "S": "u938" } }'
スキャン
% awslocal dynamodb scan \
--table-name vote
None 2 2
DT 20220512

get-item
% awslocal dynamodb get-item \

ローカルのコマンドではなく、Docker で動かす
% git clone git@github.com:localstack/localstack.git repo
% cd repo
% docker-compose up -d
EC2 起動
% awslocal ec2 run-instances
ID リスト表示
% awslocal ec2 describe-instances | jq -r '.Reservations[].Instances[].InstanceId'
インスタンス詳細
% awslocal ec2 describe-instances --instance-ids "i-xxxxxxxx"
終了
% awslocal ec2 terminate-instances --instance-ids "i-xxxxxxxx"
タグ付き
% awslocal ec2 run-instances --tag-specifications 'ResourceType=instance,Tags=[{Key=env,Value=prod}]'
出来たインスタンスはこんな感じ。
もちろん VPC とかは作ってない。
