    Hi Carl - I am reading this post [0] for the first time.. Are there
    sources to the Rocker container build for geo that we may look at, here
    at OSGeoLive ?   The purpose is to coordinate, for the benefit of users,
    versions and components under Ubuntu Focal.

Carl B. replies:

we've just added the RSPM binaries to the (Ubuntu 20.04-based) rocker-versioned stack, (4.0.x), should appear on the rocker/geospatial images (tags: latest, 4.0.0, 4.0.1 and 4.0.2) soon. 
It's already been there on the rocker/geospatial:4.0.0-ubuntu18.04 image too.

Rocker Discussion - 2020 ​here

The R Spatial Docker lead ​Carl reports that they have a Docker image updated to UbuntuGIS Focal --

base --> (rocker/geospatial:latest) use the Ubuntu-focal libs, yielding Universe GEOS 3.8.0, GDAL 3.0.4, PROJ 6.3.1

secondly, they have a named version that pulls from UbuntuGIS specifically -> (rocker/geospatial:ubuntugis) yielding UbuntuGIS GEOS 3.8.1, GDAL 3.1.3, PROJ 7.1.1

third, they would like to build a setup that compiles the chain from source, but that is not ready now .. I suggested they start with GDAL 3.2x GEOS 3.8x PROJ 7x

over time, that last one could also be used for GEOS 3.9 dev, and I know the GEOS team wants that

from a Marketing point of view, I included "we/OSGeo dot org are interested to work well with the greater R community. and be appropriately visible to your users", so a logo added somewhere, a README entry .. things like that..
