[Pywps-dev] gdal in docker

[Adam Laža]

Hello everyone,

finally I've found the problem. It's necessary to compile GDAL with xerces,
expat and geos. For geos and expat there are alpine packages, xerces has to
be installed manually.
Updated Dockerfile is attached. Probably there is a smoother way how to
have pywps-demo docker with GDAL but at least this one works.

Cheers,
Adam
