+# chDB on AWS Lambda
+
+> Running chdb in a lambda function for fun a profit!
+
+This guide is based on [this article](https://medium.com/@skalyani103/python-on-aws-lambda-using-docker-images-5740664c54ca)
+
+## Upload Docker image on ECR and Lambda
+Lambda function continers must be hosted on the AWS Elastic Container Registry.
+
+1. Export your AWS account id in the shell or better yet, add it your ~/.bashrc or ~/.bash_profile 
+```
+$ export AWS_ACCOUNT_ID = <account_id>
+```
+
+2. Install the AWS CLI and configure with your AWS credentials
+```
+$ aws configure
+```
+
+3. Review and execute the ‘deploy.sh’ script:
+```
+$ ./deploy.sh
+```
+
+4. Create Lambda function and attach your ECR Image
+
+5. Test your Lambda function:
+
