QUESTION
I am trying to mount a directory called rstudio which is residing in /mnt/rstudio. But when I try to mount using persistent volume, the directory is showing up but not the files inside rstudio. Here's my deployment file
...ANSWER
Answered 2020-Aug-18 at 14:24LGTM. I am getting files if I swap the image with nginx. I would check two things:
- Permissions: Check what permissions the files have. You may have to update your permissions or UID to access the files.
- Does
rstudioimage use that path? It may be processing that folder when it starts. Try mounting to a different path and see if you can see the files.
Also, make sure you are launching the pod on the node where the host path exists. I am assuming testserver.local and test-server are the same.

We have 3 cleints namely- TestingClient, ITestingClient and ITestingClientExtension. Ideally we would like to assign a variable in our winform. In order to assign the variable we declared
TestingClient client = new TestingClient(new Uri("https://rserver.contoso.com:12800")); We get an error stating delegation handler is protected. How do we establish this connection. Thank you
TestingClient.cs begins with this:

Answered 2020-Jun-24 at 07:35In a nutshell, you should use one of the public constructors rather than your current attempt to use one of the protected ones. Here's a screenshot (with public constructors in yellow) from a recent client I generated for that APIs, in the same way yours was generated ("Add REST Client").
For example, your code will need to look more like

When I attempt to login to the server, I get through the username and password screen just fine (it rejects bad username/password combinations, and accepts the correct one). However, once I enter my username and password, it stalls for a moment with a message that reads Unable to connect to service.

QUESTION
RStudio Server is failing to log in user when SELinux is enforcing. There is a long list of SELinux errors, starting with:
AVC avc: denied { setpgid } for pid=32444 comm="rserver" scontext=system_u:system_r:init_t:s0 tcontext=system_u:system_r:init_t:s0 tclass=process permissive=0
RStudio Server runs fine when SELinux is in permissive mode, albeit with a lot of alerts:
RStudio maintainers don't consider this a bug and closed the issue. Meanwhile, given how niche RStudio Server is, it might be a while before Fedora implements SELinux policy for it, though they have not rejected the request.
Is anyone running RStudio Server successfully with SELinux enabled?

QUESTION
I have a data frame with columns
...ANSWER
Answered 2019-Jun-08 at 05:24I think you just need to specify that you're looking for duplicates in shipment_id. However, that will just keep the first version which would have nothing in the shipped_at column. So you might need to sort the column by the shipped_at and packed_at columns (in reverse, so that null values are at the bottom). Does this work?

QUESTION
I have R 3.4.0 installed to /home/ubuntu/software/R/R-3.4.0/bin, which is a 'non-standard' install location. I then installed rstudio server, and edited the rserver.conf file to include: rsession-which-r=/home/ubuntu/software/R/R-3.4.0/bin
I thought this would be sufficient. At ip:8787 the rstudio server login box appears, and I can login, but then get an error that no session was found.
I also tried adding to the rserver.conf file:

QUESTION
I've read through this answer but for the life of me, I can't figure out this one out.
I have an Ubuntu 18 EC2 instance running RStudio Server and RStudio Connect, both using default configuration and listening on ports 8787 and 3939 respectively.
Here are my config files:
...ANSWER
Answered 2019-Apr-02 at 11:54I just figured out the answer myself. There was absolutely nothing wrong with my configuration. Opening up all the TCP ports in my security group was a bit overkill maybe and entirely unnecessary, so don't do that.
The issue was that the corporate network I am connected to blocks outbound traffic to external hosts on certain non-standard ports.
If you're in the same boat as me and need to host 2 services on the same EC2 instance but don't know which ports are unavailable/blocked by your organization then you could use nmap and portquiz.net to figure it out.
nmap is a port scanner and portquiz.net is a service that listens for connections on all TCP ports. You could scan the host using nmap over a range of TCP ports you're interested in using and see which ports show up as open
QUESTION
I am spinning up an instance of rstudio server and I need the working directory of R to be a specific directory. I would also like the file pane in the bottom right corner to be pointing to the same directory. Is there a way to do this? Currently it runs from the home directory of whichever user is running the program. I have tried the --server-working-dir flag, and it does not seem to work. Here is the command I am using:
ANSWER
Answered 2018-Jul-30 at 22:56You can do this by edditing the (global) R profile startup script. Here's a step by step guide:
1) Run Rscript -e "R.home()" -- this will tell you the location of your R directory home. In my case (Mac) it is /Library/Frameworks/R.framework/Resources
2) Go to /Library/Frameworks/R.framework/Resources/etc -- e.g., $R_HOME/etc
3) sudo touch Rprofile.site if it doesn't exist, then sudo nano Rprofile.site
4) Add the following lines and save:
