使用 docker、rbase 和 RODBC 连接到 sql 服务器时出错

Question

I'm trying to access a SQL Server on a local intranet with R, where R is loaded in a docker file with R-base.

On my desktop, I create a ODBC driver and it recognizes my windows credentials with the following:

odbcDriverConnect('driver={SQL Server};server=<serverName>;database=<dbName>;trusted_connection=yes')

Using R-base, after a lot of trial and error I was able to get RODBC installed, but I have no idea how to connect to this server.

Warning messages:
[RODBC] ERROR: state 01000, code 0, message [unixODBC][Driver Manager]Can't open lib 'SQL Server' : file not found

The DockerFile, which was built with a lot of trial and error. I'm sure much of it is redundant. Also I exposed ports which I found doing some research but I have no idea if they are needed to be exposed.

FROM openanalytics/r-base

EXPOSE 3838
EXPOSE 8787

Once I build the file, I enter R studio and use install.packages("RODBC")

How can I connect to the SQL server from the docker file?

----------Update

after creating a docker container with Ubuntu, I found that I was not able to ping the server name. I was however, able to ping the server ip address.

I modified the search string to ping the ip address, and changed the driver, as follows:

odbcDriverConnect('driver={ODBC Driver 17 for SQL Server};server=<serverName>;database=<dbName>;trusted_connection=yes')

This still did not work.

Answer 1

I could not figure out how to connect to the database with the Windows credentials of the docker host inside of the docker virtual machine.

I had to make a username and password for the database and connect with that.

Answer 2

I think if you change your driver to FreeTDS this will work. R doesn't support Sql Server drivers unless its a pro plan.
