modifying Thumbor conf value on Mac OS X (RESPECT_ORIENTATION = True)

I need to change the Thumbor to not rotate images by default by changing this config value RESPECT_ORIENTATION = True to avoid the case like the attached image (basically all landscape mobile photos)

(I’m befuddled why RESPECT_ORIENTATION is False by default? Why would we want Thumbor to rotate an source image w/out explicitly asking for it?)

I’m on Mac OS X (High Sierra) - checked out repo, set up Python w/ virtualenv, ran ./build-s3-dist.sh {{bucketname...actually doesn't matter}} and all compiled well locally - then I uploaded the generated file from dist/serverless-image-handler.zip into an s3 bucket (needed to do that rather than direct upload since > 50MB) and then uploaded from the associated Lamda.

Excited to see my images not rotated…but got an internal server error trying to render an image and looking at CloudWatch see the following:

Unable to import module 'image_handler/lambda_function': /var/task/PIL/_imaging.so: invalid ELF header

Almost sure this is b/c I’m compiling in an environment that (OS X) that doesn’t match that of the Lamda. (@arahayrabedian apparently had more luck: https://github.com/awslabs/serverless-image-handler/issues/11 - guessing he was on Linux?)

Any hints? Do I need to spin up an EC2 Linux or use Docker?

This is a lot of pain for a 1 line change! I wish Thumbor config files be adjusted from Lamda environment variables, but I believe they’re build time so not possible.

Update - was able to finally get this to work - posting a summary overview here for anyone else who is on a Mac and wants to make changes to the default Thumbor config

1. Check out this project
2. Make the one line (or more) edits per above in source/image_handler/thumbor.conf file
3. Download and install Docker: https://docs.docker.com/docker-for-mac/install/
4. Follow this basic outline from blog post and leverage this set of AWS Lamda specific built docker images to create a docker container based on the Lamda Python 2.7 environment and mount the directory of this project: - docker run -v <directory with this project>:/working -it lambci/lambda:build-python2.7 bash
5. Within that Docker container, follow the README steps to set up the environment. (Note you are already root, so don’t need sudo. Also skipped these steps: sudo yum-config-manager --enable epel and alias sudo='sudo env PATH=$PATH')
6. Within Docker container, per the README here, cd deployment and ./build-s3-dist.sh source-bucket-base-name (note that you can use anything for the bucket name since the only file you care about is the deployment/dist/serverless-image-handler.zip file that gets generated following all of this)
7. Load that .zip into your Lamda from the AWS UI (it’s probably larger than 50MB, so will need to use S3 as an intermediate step or AWS command line if you’re fancy)
8. Bask in the wonder of unrotated images

Sorry for the delay - I was able to get RESPECT_ORIENTATION to indeed work based on the Lamda env variable change only. I think I must have been testing w/ an already rotated image 🤦‍♂️ - closing this one out thanks for your help @stevemorad
