# lambda 함수 생성하기

      "Action": "sts:AssumeRole"
    }
  ]
}
```

## 2. role 생성하기(CLI 사용)

```
aws iam create-role
--role-name basic-lambda-role
--assume-role-policy-document file://policy.json

```

## 3. 어플리케이션 압축

```
zip -r lb-test.zip index.js
```

## 4. 배포 및 람다함수 생성

```
aws lambda create-function --region ap-northeast-2 --function-name lb-test --zip-file fileb://lb-test.zip --role arn:aws:iam::************:role/basic-lambda-role --handler index.handler --runtime nodejs4.3 --memory-size 128
```

## 5. 람다함수 생성여부 파일로 출력

```
aws lambda list-functions --profile **** > lambda-functions.txt
(주의 : aws account 가 여러개일 경우 --profile {aws ID 입력})
```

## 6. 람다함수 호출 및 결과로그 출력

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://molla4455.gitbook.io/dev-log/aws/create-function.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
