# Start a container that mimic the lambda environment
docker run -it --rm --entrypoint bash -e ODBCINI=/var/task -e ODBCSYSINI=/var/task -v "$PWD":/var/task lambci/lambda:build-python2.7
# Then, download ODBC source code, compile and take the output
curl -O
tar xvzf unixODBC-2.3.5.tar.gz
cd unixODBC-2.3.5

run with

 yum install unixODBC --disablerepo=amzn*

you need to bypass the amzn repolist for installing correct unixODBC

Hi Everyone!

I am facing a similar problem as most of you did before!
May be I am missing something!! :(

The Test Script works locally inside the docker container.
Could you please help me understand the steps that needs to be done after you zip the files.

This is what i did -

I created a and added inside the zip folder
Created a zip of it and uploaded it to the Lambda function ( Not as a layer)
Contents of my zip are :
total 12
drwxr-xr-x 3 root root 4096 Nov 20 23:28 microsoft
drwxr-xr-x 4 root root 4096 Nov 20 23:28 mssql-tools
drwxr-xr-x 3 root root 4096 Nov 20 23:22 python
bash-4.2# cd /opt
When i try to run the lambda it throws me an error saying that no module named "pyodbc"
Appreciate any help here! been stuck at this for a while now!

Hi @rags1357! The gist I provided above has been updated with a comment that includes steps to test locally with AWS SAM. It includes a template.yaml with embedded python test code.
