rocker/shiny-verse latest vs 3.6.3 about shiny

[cboettig]

shiny-verse:latest uses the same S6 init system as on the RStudio instances. The docker instance should still run in the same way, the running instance should be listed by docker ps as before. You'll have to give us more details about how you are running your Dockerfile for us to debug -- both images seem ok on my end. Re-open as needed here!

I attached my Dockerfile here.

FROM rocker/shiny-verse:latest

COPY ./TestPlant /srv/shiny-server/TestPlant

EXPOSE 3838 

RUN sudo chown -R shiny:shiny /srv/shiny-server 

ENTRYPOINT sh wrapper.sh

docker build -t test_ui_ver4.0:ver4.0 testUI_ver4.0
docker run --name TestPlant --rm -d -p 38381:3838 test_ui_ver4.0:ver4.0
docker ps

when using "FROM rocker/shiny-verse:latest", I cannot get anything when docker ps

PS E:\Test\rstudioshiny> docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

but with "FROM rocker/shiny-verse:3.6.3", I can get below:

PS E:\Test\rstudioshiny> docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                     NAMES
47913b545d0d        test_ui_ver4.0:ver4.0   "/bin/sh -c 'sh wrap…"   4 seconds ago       Up 3 seconds        0.0.0.0:38381->3838/tcp   TestPlant

I suspect the issue is with the library RODBC, as version 1.3-16 works only for R version 3.6.3 and below. When I install the package RODBC as from above Dockerfile, without specifying the version, it is getting the latest version of 1.3-17, which does not work with R version of 3.6.3:
package RODBC is not available (for R version 3.6.3)

Not sure if I am clear in the explanations. It would be excellent to get the "FROM rocker/shiny-verse:latest" to produce the container when docker ps, as I need to get that package RODBC to work.

Thanks.

Please see my above comments.

It seems that the script you have set as the ENTRYPOINT is not functioning properly.
As mentioned in the comments above, rocker/shiny images =>4.0.0 have S6's /init set to the CMD, so your shell script wrapper.sh may not be handling it correctly.
Try to run it without setting the ENTRYPOINT
