Could not let this go without a last try.

I finally managed to create a working lambda layer using the Dockerfile from https://github.com/developmentseed/geolambda as a starting point and with a more than a few hacks got GDAL to compile within the docker and then compile the swig bindings and then create a working layer zip using the package.sh from within the docker image as a starting point.

Thanks for the help!

Best,

Ari

Hi Ari,

You can have a look at https://github.com/lambgeo/docker-lambda
It doesn’t provide any python bindings but if you follow https://github.com/lambgeo/docker-lambda#2-advanced-need-other-dependencies you can create a lambda package with all the deps you need.

*Subject:*[gdal-dev] AWS Lambda layer with GDAL python bindings

Hi,

I need an AWS Lambda layer with GDAL python bindings, for "from osgeo
import gdal", but it seems difficult to make such a layer.

In fact all I need is gdal.Open and gdal.BuildVRT - I have not dug
deeper into rasterio, can it do those?

Anyway, I installed GDAL on a machine with python 3.8 as that's what to
lambda runtime will be, and from there copied files to a zip with /lib
and /python. The /lib is for the shared objects. I have now 94 libraries
there. The error I now get from

try

     from osgeo import gdal

except

in the lambda is

ImportError: /lib64/libm.so.6: version `GLIBC_2.27' not found (required
by /opt/lib/libgdal.so.29)

this seems to be a problem as that's the lambda's libm and not the libm
in /lib, which I assume should work.

Anybody know a solution? I tried some recipes I found from the net howto
build such a layer but they did not work for me out of the box, so I
tried myself.

Best,

Ari
