crash rstudio pro kubernetes launcher

[Scipion]

Hello,

i am trying to install rstudio in my infrastructure, but i encounter errors . I can use rstudio in locally but not with kubernetes.

i followed this tutorial for the installation

Integrating RStudio Server Pro with Kubernetes - RStudio Documentation

My version of rstudio

[root] # rstudio-server version
1.4.1103-3 Professional (Wax Begonia) for CentOS 7

I took the docker image in dockerhub, it's juste the rstudio/r-session-complete, without any modification

https://hub.docker.com/r/rstudio/r-session-complete

when i test the user, i have this error

[root] # rstudio-server verify-installation --verify-user=test

Hi @Scipion,

If you're using RStudio Server Pro, you have access to RStudio's premium support. I'd encourage you to file a ticket there if you haven't already. They'll be able to help you out.

How do I submit a Support ticket?

[Scipion]

hello,

thank you for your advice, i opened a ticket support yesterday and they gave me the solution, that was a compatibility problem between the version of rstudio server and the docker image of rstudio session.

Fantastic. Glad to hear this was resolved, and thanks for posting the resolution here in case others run across the same!
