Developing

Chalice-Bot depends a Pillow - Python Imaging Library. So If you want to create deploy package for AWS Lambda, you must prepare the Amazon Linux. However, it is very inconvenient to create an instance of EC2 for that. So please use Dockerfile.deploy.

Setup

Create .chalice/config.json :

$ cat .chalice/config.json
{
  "app_name": "linebot", 
  "stage": "dev"
}

Environment Variables on your local machine

export AWS_ACCESS_KEY_ID=xxxxxxxxxxxxxxxxxxxx
export AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
export AWS_DEFAULT_REGION=ap-northeast-1
export S3_BUCKET_NAME=xxxxxxxxxxx

export LINE_BOT_CHANNEL_ACCESS_TOKEN=
export LINE_BOT_CHANNEL_ACCESS_SECRET=

Deploy to AWS Lambda and API Gateway

Deploying by chalice cli:
