QUESTION
I have a R Notebook created in databricks with some code running in it. The R script creates a csv file that I need to upload to a specific storage account blob container. To access the blob storage I have a SAS (Shared Access Signature) String. I found out an R package 'AzureStor' that connects R to Azure Storage. Is there a specific command I can use to connect to blob storage using this SAS string and write the csv file directly to the container folder? I am new to databricks and trying to automate an upload process to Azure blob storage.
...ANSWER
Answered 2019-Dec-30 at 08:19As I known, there are two ways to write a csv file from R Notebook in Databricks to Azure Blob Storage, as below.
Please refer to my answer for the other SO thread How do I upload a R dataframe as a CSV file on Azure blob storage? to use
AzureStor
installed byinstall.packages("data.table")
to write a R dataframe as a csv file into Azure Blob. The sample code is like as below.
QUESTION
I'm trying to build an image base on R-base, following the multi stage method. How can I copy the installed packages from the 1ste stage into the 2nd stage? And nothing else?
The current file gives me basically a 'packageless' R-base version. So the packages installed in the 1ste stage are 'lost' somewhere.
I think it has something to do with making and choosing the correct directories. This is a confusing part for me, since I'm fairly new to dockerizing applications.
Thanks for all your help!

Answered 2019-Oct-29 at 20:41In the comments you note that you want to get rid of any excess 'weight'. The latter typically comes from having development tools and packages installed. Now the rocker/r-base
image brings in quite a bit of weight already, since it has r-base-devel
with its dependencies installed. However, we can try to not add further weight by having only the run-time dependencies in the final image by getting rid of the build-time dependencies. Build-time dependencies that are not necessary at run-time for an R package are typically development files like header files for system libraries, e.g. you don't need the libxml2-dev
package at run-time. The libxml2
package would be enough.
I see several possible approaches to this.
First, you could use binary packages for those packages that need compilation against system libraries. I have not checked the dependencies for AzureStor
, but it might well be that all the required R packages exist as compiled Debian packages. These will only depend on the run-time dependencies keeping the images size small and the build time short. Your Dockerfile
would look something like this:
