Current Behavior

When trying to analyze the HelloWorld example application following the steps defined here, I get the following error:

Where I run the analysis:

abrugaro@fedora:~/analyzer-lsp$ go run cmd/analyzer/main.go \
    --provider-settings external-providers/dotnet-external-provider/examples/HelloWorld/provider-settings-example.json \
    --rules external-providers/dotnet-external-provider/examples/HelloWorld/rule-example.yaml

UNKN[0000] rules parsed                                  logger=parser parsed=1
ERRO[0000] unable to load rule set                       error="stat external-providers/dotnet-external-provider/examples/HelloWorld/ruleset.yaml: no such file or directory" logger=parser
ERRO[0000] Error inside ProviderInit, after g.Init.      error="chdir /home/abrugaro/analyzer-lsp/external-providers/dotnet-external-provider/examples/HelloWorld: permission denied" logger=dotnet provider=grpc
ERRO[0000] unable to init the providers                  error="chdir /home/abrugaro/analyzer-lsp/external-providers/dotnet-external-provider/examples/HelloWorld: permission denied" provider=dotnet
exit status 1

In the running podman container:

ERRO[0043] failed to start language server process       client=2637543189119697618 error="chdir /home/abrugaro/analyzer-lsp/external-providers/dotnet-external-provider/examples/HelloWorld: permission denied" provider=dotnet

It says permission denied in both places but I can't locate where exactly is the permissions issue.

Expected Behavior

The analysis should complete successfully and generate the output.yaml file as defined in the Readme.

Is it possible @abrugaro that you need to deal with SELinux? Looking at this stack overflow answer it appears that it would look something like:

podman run -it --rm -P -u 1000:1000 \
    -v $PWD/external-providers/dotnet-external-provider/examples/:$PWD/external-providers/dotnet-external-provider/examples/:z \
    quay.io/konveyor/dotnet-external-provider:latest

Can you confirm?

[abrugaro]

Hi @djzager you were right, now the analysis completed successfully, it could be beneficial to mention the SELinux possible issue in the README file.

On the other hand, I got this error in the analsysis output, I don't know if that's expected.
