Simple Mustache Service is an AWS Lambda demo that uses this module
This is a simple script that builds a deployment package including OpenCV compatible with the AWS Lambda Python runtime. The dynamic library is compiled with all extended instruction sets supported by Lambda CPU and binaries are stripped to save space. You simply need to add your code inside lambda_function.py and possibly your haar cascades files or additional Python modules. You can directly download a pre-built archive.
- Build duration: ~20 min on T2.micro / ~15 min on C4.2xlarge
- Package size without haar cascades included: 26MB
- OpenCV 3.1 by default but may work with newer
Needs to be built on an Amazon Linux instance.
- Download the repo
wget https://github.com/aeddi/aws-lambda-python-opencv/archive/master.zip - Unzip the archive
unzip master.zip - Launch the script
cd aws-lambda-python-opencv-master && ./build.sh
In the EC2 console, launch a new instance with:
- Amazon Linux AMI
- Role with S3 write permission
- Shutdown behavior: Terminate
- Paste the script below in the user data text field
#!/bin/bash
yum update -y
yum install -y git cmake gcc-c++ gcc python-devel chrpath
cd /tmp
wget https://github.com/aeddi/aws-lambda-python-opencv/archive/master.zip
unzip master.zip
chmod 777 aws-lambda-python-opencv-master
cd aws-lambda-python-opencv-master
su -c './build.sh' ec2-user
aws s3 cp lambda-package.zip s3://<my-target-bucket>
shutdown -h now- Replace my-target-bucket by a bucket or your choice
- Less than 30 min later the instance will be terminated and the archive will be available on your bucket
