Question

I notice that documentation increasingly points to GCR hosted versions of the images. Are there any plans to phase out Docker Hub hosted images?

And on a different note (saving time by asking as a single question): any plans to migrate to Ubuntu 22.04 as the base image?

Update on this, I see the geospatial image is still based on 20.04 after running this command:

docker run --rm -ti rocker/geospatial 

Any ideas when it will be updated to 22.04? Looking at the build scripts I guess that depends on the RSPM.

The purpose is to enable the use of GHCR when a connection to DockerHub is not available. See #371.
(Of course you can use GHCR as your main registry instead of DockerHub; there is no difference in the images that are pushed.)

I see no reason to stop using DockerHub at this time.

Switching to ubuntu:jammy is tracked in #282.
The rules for version selection are documented here. https://github.com/rocker-org/rocker-versioned2/wiki/Versions

The actual Ubuntu version selected is chosen at the following line in the script.

rocker-versioned2/build/make-stacks.R

Line 441 in e7c1878

dplyr::filter(r_release_date >= ubuntu_release_date + 90) |>

Since it has now been more than 90 days since the release of Ubuntu 22.04, the base image will be switched in the next release, R 4.2.2.

Many thanks for the clarification, great news that there's no pressure to switch. Looking forward to R 4.2.2!
