I am trying to publish my Azure Functions App to Kubernetes but I am getting the following error when I run this command
func kubernetes deploy --name my-function-api --namespace default --registry mycontainerregistry/docker-azure-function --csharp
Unable to find project root. Expecting to find one of host.json, local.settings.json in project root.`
This is my docker file
FROM mcr.microsoft.com/dotnet/sdk:3.1 AS installer-env
COPY . .
RUN cd /MyFunctionApp.Api && \
mkdir -p /home/site/wwwroot && \
dotnet publish *.csproj --output /home/site/wwwroot
COPY /MyFunctionApp.Api/host.json /home/site/wwwroot
COPY /MyFunctionApp.Api/local.settings.json /home/site/wwwroot
# To enable ssh & remote debugging on app service change the base image to the one below
# FROM mcr.microsoft.com/azure-functions/dotnet:2.0-appservice
FROM mcr.microsoft.com/azure-functions/dotnet:3.0
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
AzureFunctionsJobHost__Logging__Console__IsEnabled=true
COPY --from=installer-env ["/home/site/wwwroot", "/home/site/wwwroot"]As you can see I have tried adding the following lines
COPY /MyFunctionApp.Api/host.json /home/site/wwwroot
COPY /MyFunctionApp.Api/local.settings.json /home/site/wwwrootBut that does not seem to help either, so not sure what I need to do to get this working? Any help would be appreciated.
Ok so figured this out. Azure Functions does not read local.settings.json or settings.json when running in a container. These keys need to be set as environment variables.
You need to have the local.settings.json in the the same folder that you run the func kubernetes deploy command from and that will generate a yaml file with the settings that get passed into the container when it is started.
NB: this does not seem to work with setting CORS settings. I have a new question for that here https://stackoverflow.com/questions/65074215/cors-issue-with-azure-functions-inside-aks-cluster
