Azure Functions Core Tools v4 unable deploy to Kubernetes

G:\Projects\funapp2>func --version
4.0.3928

G:\Projects\funapp2>dotnet --version
6.0.100

Here are the steps to reproduce the problem.

mkdir funapp2 && cd funapp2
func init --worker-runtime dotnetIsolated --docker
func new -t "HttpTrigger" -n "Login" -a "anonymous"

Modify the Dockerfile file as below:

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS installer-env

COPY . /src/dotnet-function-app
RUN cd /src/dotnet-function-app && \
    mkdir -p /home/site/wwwroot && \
    dotnet publish *.csproj --output /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-isolated:3.0-dotnet-isolated5.0-appservice
FROM mcr.microsoft.com/azure-functions/dotnet-isolated:3.0-dotnet-isolated5.0
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

COPY --from=installer-env ["/home/site/wwwroot", "/home/site/wwwroot"]

Build & Push image

docker build -t willh/funapp2:latest .
docker push willh/funapp2:latest

Deploy my function app with --dry-run

func kubernetes deploy --name funapp2 --service-type NodePort --image-name willh/funapp2 --dry-run

There is only Secret been created.

Where is the other YAML of the deployment?

I created a PR to resolve this issue inside the functions tooling: #3000

In the meantime, if you want an immediate fix on your project’s side, I also created a helper program that does that. It is published as a NuGet package Az.Functions.MetadataToJson (repo on GitHub)

Just add a reference to it in your project file and it should make the func kubernetes deploy work as expected.

@MACEL94 It seems nobody watching this repo. I reported a few issues that is been stalled for more than 1 month.
