I created a Container Application for Kubernetes in Visual Studio as follows:
Docker file looks like this:
Result from running in Powershell with success:
I tried using the pipeline template - Deploy to Azure Kubernetes Service:
I used the YAML "as-is":
When I save and run, I get the following:
[error]COPY failed: stat /var/lib/docker/tmp/docker-builder947419078/KubeApp/KubeApp.csproj: no such file or directory

[error]COPY failed: stat /var/lib/docker/tmp/docker-builder947419078/KubeApp/KubeApp.csproj: no such file or directory
The cause of this error is actually due to the different execution mechanisms between pipeline and local when running the dockerfile.
For pipeline, it is by default running the docker in the directory where the dockerfile lives which is at the project level, but VS/local runs it at the Repos/Solution level.
So, to solve this issue, you can try with below method
Change the COPY definition as:
COPY ["KubeApp.csproj", "KubeApp/"]This method can let you succeed to COPY, but failed with Program does not contain a static 'Main' method.
At this time:
- One way is change the
COPY . .(L10) toCOPY . KubeApp/. This will add folder to dest path. - Or, you can change the order of
COPY(L10) andWORKDIR(L11) without change theCOPY . ..
See my previous answer that others solved the same issue by applying my suggestion.
