This example does not work when you publish/run in WSL 2

[samgithub]

My target platform is a linux-64, so I am pre-publishing the microservice using Step 1: dotnet publish -c Release -o publish -r linux-x64

Then I create an image using docker build -t microservice -f Dockerfile .

Then create a container within WSL Ubunto 20.0.4

docker run -it --rm -p 3000:80 --name microservicecontainer microserviceI

Problem : I cannot access the service from a browser on Win10) (http://localhost:3000)

---

Results From docker run in WSL info: Microsoft.Hosting.Lifetime[0] Now listening on: http://localhost:5000 info: Microsoft.Hosting.Lifetime[0] Now listening on: https://localhost:5001 info: Microsoft.Hosting.Lifetime[0] Application started. Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0] Hosting environment: Production info: Microsoft.Hosting.Lifetime[0] Content root path: /publish info: Microsoft.Hosting.Lifetime[0]

I noticed that Ketrel was listening to 5000 and 5001

So I changed the run to: docker run -it --rm -p 5000:80 --name microservicecontainer microserviceI BUT http://localhost:5000 doesn't work either.

My Dockerfile

---

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 COPY ./publish /publish WORKDIR /publish ENTRYPOINT ["dotnet", "myMicroservice.dll"]

---

The example as shown does work - but its strictly a Windows sample. REQUEST: Can you provide the same sample, publish to a Linux-64 target; and run it under WSL? --- please.

Where are you seeing this example @samgithub?

Adding @shirhatti and @nishanil to help here

We do offer Linux versions of the tutorials too - just click on the Linux tab: https://dotnet.microsoft.com/learn/aspnet/microservice-tutorial/intro?initial-os=linux

And then we also have a deployment one: https://dotnet.microsoft.com/learn/aspnet/deploy-microservice-tutorial/intro?initial-os=linux

Does that help?

[samgithub]

Thanks for your response and attention to this matter.. Actually I already looked at the Linux tabs and they essentially involve using Linux as the development environment. Just to avoid confusion my process is as follows:

1) Development environment Win 10 - Visual Studio 2) Publishing TARGET : Linux (using dotnet publish -c Release -o publish -r linux-x64) 3) Create a docker image from the linux bits in the publish folder. 4) Create a container from step (3) in WSL (Ubuntu)

The above steps are fine BUT navigating to localhost:3000/weatherforecast ---> DOES NOT WORK.

[samgithub]

Since VS is cross-platform and allows publishing to different targets, an example would greatly help. Thanks

@shirhatti @nishanil can you help on this issue?

[nishanil]

hey @samgithub ! I followed the exact steps listed on that the page and was able to run it inside WSL. See this video: https://1drv.ms/u/s!AupZwrZ-sEsggZw9dmMeGjgZe7oG-Q?e=Dfn1ru

[nishanil]

I added some log info for you. Try executing the exact steps listed in the page https://dotnet.microsoft.com/learn/aspnet/microservice-tutorial/intro?initial-os=linux first. Then compare the code with yours to see what you were doing wrong,

[samgithub]

Are you creating a LINUX IMAGE? That's what I'm talking about. The Windows image works. Its the publish to linux-x64 and Use a container from it that does not work.

Yes, it is a Linux image. See the OS Version.
