# Deploy-Python-Docker-Image-on-AWS-Lambda

This project aims to get the current Bitcoin price using an API call. We build this project using AWS CDK, Docker, and AWS lambda. 

### Create AWS CDK project 

```

cdk init app --language typescript

```



### Create a Python hander and a docker file

  - create a folder image and sub-folder src

  - create a Python file inside /src.

  - create a docker file and a requirements file inside the image.

### configure the files

##### Dockerfile

```

# Base image

FROM public.ecr.aws/lambda/python:3.11

# Copy requirements.txt

COPY requirements.txt ${LAMBDA_TASK_ROOT}

# Install the specified packages

RUN pip install -r requirements.txt

# Copy all files in ./src

COPY src/* ${LAMBDA_TASK_ROOT}

#Set the CMD to your handler

CMD ["main.handler"]

```

#### requirements.tx

```

requests

```

#### docker-lambda_stack.ts

```

import * as cdk from "aws-cdk-lib";

import { Construct } from "constructs";

import * as lambda from "aws-cdk-lib/aws-lambda";

export class DockerBitcoinStack extends cdk.Stack {

  constructor(scope: Construct, id: string, props?: cdk.StackProps) {

    super(scope, id, props);

    const dockerFunc = new lambda.DockerImageFunction(this, "DockerFunc", {

        code:lambda.DockerImageCode.fromImageAsset("./image"),

        memorySize: 1024,

        timeout: cdk.Duration.seconds(10),

    });

    const functionUrl = dockerFunc.addFunctionUrl({

        authType:lambda.FunctionUrlAuthType.NONE,

        cors: {

            allowedMethods: [lambda.HttpMethod.ALL],

            allowedHeaders: ["*"],

            allowedOrigins: ["*"],

        },

    });

    new cdk.CfnOutput(this, "FunctionUrlValue", {

        value: functionUrl.url,

    });

  }

}

```

#### Test the docker image locally

```

docker build -t docker-image:test .

docker run -p 9000:8080 docker-image:test

```

### Deploy the project on AWS

```

cdk bootstrap -region <>

cdk deploy

```
