ZIP by executing PIP in Lambda's Docker container. A script that publishes it as an AWS Lambda Layer.
--Doker installation required (PIP in lambci / lambda image)
--Please configure AWS in advance.
--Save the following source code as a file (publish.sh) and grant execute permission. `` `chmod + x publish.sh --Execute by specifying parameters (param1 = layer-name, param2 = lib-name, param3 = lib-version, param4 = python-version) -./publish.sh requests-python37 requests 2.22.0 python3.7```
--If you specify the same Layer-name and re-execute, a new layer-version will be created.
It's not easy to make, but it works. .. .. Please when you do not want to pollute the environment at hand.
#
# Require: docker installed.
# Require: aws config for publishing lambda layer
#
# 1. in container, pip install python liblary and zip,
# 2. publish to aws layer
#
# Usage: param1=layer-name, param2=lib-name, param3=lib-version, param4=python-version
# ex ```./publish.sh requests-python37 requests 2.23.0 python3.7```
layername=$1 # requests-python37
lib=$2 # requests
ver=$3 # 2.23.0
env=$4 # python3.7
zip=$lib-$ver-$env.zip # requests-2.23.0-python3.8.zip
echo packing: $zip
# Prepare
mkdir -p build
rm -rf build/* # Clean up
# pip and zip in docker.
