Sprint:Algorithms Development Tools Improvements


We currently have to sets of R packages lists, one for the Prototyping Environments (the VREs with SAI) and one for the Production Environments (the VREs without SAI). The RStudio machines retrieve the packages lists from the production set, but this may cause some inconsistencies when a user is writing his code using RStudio in a Prototyping VRE and then publishes it onto DataMiner using SAI. In fact, he might be able to run his script inside RStudio without errors, while encountering issues once the algorithm is in DataMiner, because one or more of the packages he uses are not actually installed on the machines. In a perfect world the user wouldn't forget to include all the dependencies in SAI before the publication step so to have them automatically installed on the machines, but we do not live in a perfect world and if this happens we automatically have the aforementioned inconsistencies.

This ticket is meant to highlight such issue and find a solution together.

One possible way to tackle the problem consists in a distinction between RStudio machines, having the ones behind Prototyping Environments point to the Prototyping packages list, while the ones behind Production Environments points to the other set. Is it a viable escamotage? Do you have any other ideas?

I think it is the right way for avoiding this kind of issue. The proto instances could be named with the "-proto" suffix in order to better understand if an instance is synchronized with the proto repository or the production repository. @andrea.dellamico@isti.cnr.it what do you think?

#3 Updated by Andrea Dell'Amico over 1 year ago

It's doable, the R packages management is the same on both the dataminer and rstudio servers.
Renaming a node is a pain but we can add CNAMES. We need to know what VMs run as proto instances and create a group under the ansible playbook with the different configuration.

It is not that simple, really. There are several rstudio instances that are shared with both proto and production VREs. We should first completely separate the two set of instances and after we can create a separated group under the ansible playbook. In order to separate the two set, I guess we should first transfer the user's home to the new production instances.

I see. If we can wait, there's a chance that the GARR cloud people will enable CephFS for us in some weeks. With it we could mount the same home directory on every rstudio server that runs in the GARR cloud and then no more need to move home directories around.
