Application error on Linux running .net core

Question

I have deployed a .net core application onto Azure App service on Linux. It is working fine locally but on azure we get the inner exception:

The owner of '/home/.dotnet/corefx/cryptography/x509stores/my' is not the current user.

How do we proceed?

Answer 1

The right place to store your certificates is in Azure Key Vault, https://learn.microsoft.com/en-us/azure/key-vault/general/overview

Then your .NET Core application can query the certificate from there, https://learn.microsoft.com/en-us/azure/key-vault/general/tutorial-net-create-vault-azure-web-app

Answer 2

So I had to modify my code after i understood that the certs in Linux are handled differently compared to windows containers. In Linux had to load the cert file directly rather than looking for it in a store.

private X509Certificate2 GetX509CertificateLinux(string thumbprint)  
    {  
        if (string.IsNullOrEmpty(thumbprint))  
            return null;  
        string finalPath = $"/var/ssl/private/{thumbprint}.p12";  
        var bytes2 = File.ReadAllBytes(finalPath);  
        var cert = new X509Certificate2(bytes2);  
        return cert;  
    }
