Hi @shehbazk @Azhar_Shaikh ,

thanks , but maybe I was not clear

Rstudio needs a user on the host, in other words , the ones on

/etc/passwd

which right now, it contains neither workload nor machine users (we have already a machine user)

the question whether is possible to add one of an existing user to the host (as in /etc/passwd)

thanks

when I try

sudo passw [any_exisiting_user]

I get this error:

Password reset by root is not supported.

and the workload passw is not accepted by Rstudio, I guess because it looks up for passw in /etc/passwd

any idea ?

thanks

Hello @grlzz

Thanks for sharing your findings with us. I understand Rstudio needs a user on the host (and it should be present under /etc/passwd (where all the local users belongs to))

You can create and add local user on the host as workaround, but If the node where you added the user is repaired or restarted it will loose the user from /etc/passwd that you have recently added and you will need to add it again. Cloudbreak will use the predefined images and steps and as the user will be through manual creation It will not consider the added user Incase of node reboot/repair.

Hi Azhar,

thanks -- yeah, I had already used that workaround, but as I have issues with packages installation on that 'host' user's home, I still wanted to know if is possible to add the workload user on the host (namely, on etc/passwd)

Thanks,

Gianrocco

ps: start/stop does not delete the user on /etc/passwd (terminate/repair the host yes, it will)

Hello @grlzz

It would be great if you can open a support case for this, we will need to investigate on this and see the options available to implement this.
