Question

Hello kedroids I have a question about the read priority of credentials files Suppose I have a `conf base` and `conf prod` environment and my `credentials yml` file in `conf local` If I run `kedro run` will `conf local credentials yml` overwrite `conf base credentials yml` And if I run `kedro run env prod` which credentials file will be used I have the impression that it is the local file that is always used Thank you

hey so the answer is on a per key basis if the same key exists in both Also a regular kedro run can be thought of as `kedro run env base`

datajoely · Answer

I think local still wins in every case

Massinissa Saïdi · Answer

Local wins Thank you slightly smiling face

datajoely · Answer

you can mess around with your own config loader if you want to change this

Massinissa Saïdi · Answer

But it seems if I have set nothing in `local credentials yml` and smthg in `prod credentials yml` I will get None value

datajoely · Answer

hmm I wouldn t expect that

datajoely · Answer

i e the key only exists in prod

Massinissa Saïdi · Answer

yes the credentials in local was empty

Massinissa Saïdi · Answer

and I remove `local credentials yml` i got this error ```No files found in Users conf base Users conf local matching the glob pattern s credentials credentials credentials warn f Credentials not found in your Kedro project config n str exc ```

Massinissa Saïdi · Answer

Ok its maybe because I read credentials from `KedroSession` as ```KedreSession create load context get config credentials ```

datajoely · Answer

ah you need the file there

datajoely · Answer

but it can be empty

datajoely · Answer

or more specifically you need a file under the base or local folder to be present but no content is needed

Ankita Katiyar · Answer

If you do `kedro run env prod` the config will be read from `conf prod` and `conf local` will not be read

Ankita Katiyar · Answer

Essentially config is always read from the `base` directory and then the run time env config which is `local` by default but if you specify ` env prod` it will load config only in `prod`

Massinissa Saïdi · Answer

yes I think my mistake was my checking with this `KedreSession create load context get config credentials `

datajoely · Answer

sorry my mistake < Massinissa Saïdi> thanks < Ankita Katiyar>

Massinissa Saïdi · Answer

do you think its possible to get credentials infos depending of environment with a function inside code Becase this `KedreSession create load context get config credentials ` returns only what in local credentials yml

datajoely · Answer

so all of this doesn t happen in the context

datajoely · Answer

the resolution is in the ConfigLoader class

Massinissa Saïdi · Answer

with ConfigLoader class when I read the credentials with env variables it doesnt convert them

datajoely · Answer

this is how you can do it <https github com kedro org kedro issues 403>
