Question posted in 
I want to create a python function with Oracle Cloud’s function service.
To do this, I’m following the Getting started tutorial using Cloud Shell Setup.
I follow all the steps as indicated, but when I come to deploy the function with the command fn -v deploy --app DBDB_IO_Refresher.
I get this error :
Fn: error running docker build: Cannot create/use builder instance docker for oci_fn_builder : exit status 125
Here are all the instructions I followed:
fn list context
fn use context eu-marseille-1
fn update context oracle.compartment-id ocid1.********************
fn update context registry ***********/func-python
docker login -u '***********' mrs.ocir.io
fn list apps
fn init --runtime java hello-test-python
cd hello-test-python
fn -v deploy --app DBDB_IO_Refresher
Here are the details of the error:

If anyone has any ideas or needs further information, please don’t hesitate, I’ve been stuck for over a week and can’t find any solutions on the web.

I had a similar issue. The solution we found is to select shape "Generic_X86" (not X86_ARM nor ARM) when creating an Fn application at the OCI console like so:
.
Sorry for late reply. As seen in the above image, I chose Generic_X86 shape for Fn application and solve the issue.
But, my coworker encounted same issue even if he chose generic_X86 for Fn app shape. We spent a long time trying to find a solution and eventually, we identified it.
FN application shape and Cloud shell VM architecture should match.
x86-64 for FN app and X86-64 for cloud shell. OR ARM for FN app and ARM for cloud shell.
Hope it helps.
