Have been attempting to build a docker image for an azure function for the last few days. The project in question gets packages from a private feed. This feed is using azure artifacts. I have tried multiple ways to connect to the private feed based on different solutions found on the web. This involves moving some credentials into nuget.config itself and using a PAT (Personal access token) to connect to the feed, as well as using a VSS_NUGET_EXTERNAL_FEED_ENDPOITNS variable in the docker file and passing in the PAT/Endpoint there via the docker build --build arg method. All of these result in the same error.
error NU1301: Unable to load the service index for source
as noted in the docker file below, you can see commented out attempts to get the artifacts cred provider which is an entirely separate issue and I do not think it is required. If it becomes required i can debug that later, but would like to get past this not finding source error first.
