This is a template project for writing a lambda
First install the requirements for the project using pip:
pip install -r requirements.txt
The tests can now be run with:
make test
To package the lambdas run:
make build
This creates zip files with the lambda code and its dependencies. This packaging is the only way to include dependencies from a requirements.txt file inside a lambda.
In order to publish the lambdas to s3 so that they can be deployed, two variables need to be set in the makefile:
- BUILD_LOCATION - A place on s3 that you can upload the lambda zip file to
- REGION - the aws region of the s3 bucket
After those two parameters are set, build can be uploaded with the following:
make publish
As I have started using aws lambdas much more frequently, I have found them to be an excellent way of running simple deployment, maintenance, monitoring, and testing tasks. However, the initial development setup was a bit tedious to get off the ground. So I created this project.
For just working lambdas without coordination with other components http://apex.run/ looks like a pretty cool project.
- Introduce a dockerfile that can run the build steps. It can be difficult to get the correct python setup on osx.
- Add a deployment methodology. This project stops at uploading the lambda code at s3.
- Switch to pytest. It seems more full featured. I am particularly a fan of: https://github.com/joeyespo/pytest-watch
