net-snmp-aws-lambda-layer

AWS Lambda Layer for Net SNMP Tools.

Why SNMP?!

Because.

To be more clear: because I needed it as a cloud guy who works hard to integrate on-premises infrastructure with cloud. And SNMP is a reasonable way for a Lambda to extract information from decades of existing on-premises infrastructure.

This is why SNMP. :)

Building the Layer

1. Make certain you have the jasondour/amazonlinux-gcc-devel Docker image needed to build the layer.

   $ docker images
   REPOSITORY                                                    TAG                 IMAGE ID            CREATED             SIZE
   jasondour/amazonlinux-gcc-devel                               latest              64ff20963c0a        7 minutes ago       668MB
   

   1. If you do not have the images, just pull them with a docker pull command.

2. Confirm the build directory is clean.

   $ ls -1
   Dockerfile
   LICENSE
   README.md
   build.sh
   

3. Then execute the docker jasondour/amazonlinux-gcc-devel image to run the build script.

   docker run --rm -it -v `pwd`:/tmp/repo jasondour/amazonlinux-gcc-devel /tmp/repo/build.sh
   

Deploy the Layer

Once the layer zip file is created, you can deploy it to your AWS account with the following command:

aws lambda publish-layer-version --layer-name "net-snmp-58" --description "Net-SNMP Utilities for All Runtimes" --license-info "BSD-2-Clause" --zip-file "fileb://net-snmp-5.8.zip"
