GDAL in Geoserver Cloud

[ppradela]

Do these environment variables LD_LIBRARY_PATH and GDAL_DATA work in the cloud version? I have GDAL installed in my system and downloaded GDAL plugin (jar files). Will it work if I put valid paths to these variables during the containers deployment and upload the GDAL plugin using webui importer?

[groldan]

Not that easy:

• we need to install gdal-bin on the docker images. In order to do so, it'd be better if all the geoserver service images shared a common base image so they can share as many layers as possible (WIP at Use common base docker images to share layers across service images #396)
• The gdal-java package is not available anymore from the apt repositories, so we need to install gdal.jar and gdalalljni.so by some other means
• With that in place it'd be just a matter of including the geoserver GDAL and OGR extensions as maven dependencies

[ppradela]

Thanks for the reply. On the normal version of Geoserver when I used it and I wanted to have GDAL I built the Geoserver image based on the GDAL image. As far I know the Geoserver image and the GDAL image are based on the Ubuntu image.

[groldan]

yeah, I've been experimenting with options. Of which, using osgeo/gdal:ubuntu-full-3.6.3 as base image brings up the issue of it being 1.64GB, so we'd end up with ~2GB images.

note right now we have

where all of them share the layers of the base image

which is built but not pushed

Check this PR
It includes code for a GDAL base image which would facilitate multistage docker images generation.

[jemacchi]

Just for record, and some manual testing (if required).
The following Dockerfile builds a GDAL image based on the same temurin base image as in GSCloud.
And then on top of that deploys a Geoserver vanilla 2.25.3 with GRIB and NETCDF plugins included (along others, not relevant).
