How can we configure our Angular & ASP.NET Core application to load settings from a specific subfolder when the environment variable IsContainer #12162 | Support Center

Dear ASP.NET Zero Support Team,

I hope this message finds you well.

I am currently working on our ASP.NET Core & Angular project and have a couple of questions regarding the configuration of our appsettings.json files for container deployments.

Dynamic Configuration Loading: How can we configure our ASP.NET Core application to load settings from a specific subfolder when the environment variable IsContainer is set to true? We want to ensure that the application correctly uses this configuration in a containerized environment.

New Folder for Configuration Files: For both the ASP.NET Core backend and the Angular frontend, we would like to create a new, dedicated folder solely for appsettings*.json files. Instead of loading these configurations from the /assets folder in the Angular project, we want a separate clean folder. What steps should we follow to implement this structure in both projects?

Thank you for your assistance!

Hi @pliaspzero,

Please look at these documents. I think it should help. https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-8.0 https://www.roundthecode.com/dotnet-tutorials/how-to-read-the-appsettings-json-configuration-file-in-asp-net-core

ok - thanks - in ASPZERO - could I do it here?

public static class AppConfigurations
{
    private static readonly ConcurrentDictionary&lt;string, IConfigurationRoot&gt; ConfigurationCache;

    static AppConfigurations()
    {
        ConfigurationCache = new ConcurrentDictionary&lt;string, IConfigurationRoot&gt;();
    }

    public static IConfigurationRoot Get(string path, string environmentName = null, bool addUserSecrets = false)
    {
        var cacheKey = path + "#" + environmentName + "#" + addUserSecrets;
        return ConfigurationCache.GetOrAdd(
            cacheKey,
            _ => BuildConfiguration(path, environmentName, addUserSecrets)
        );
    }

    private static IConfigurationRoot BuildConfiguration(string path, string environmentName = null,
        bool addUserSecrets = false)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(path)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

        if (!environmentName.IsNullOrWhiteSpace())
        {
            builder = builder.AddJsonFile($"appsettings.{environmentName}.json", optional: true);
        }

        builder = builder.AddEnvironmentVariables();

        if (addUserSecrets)
        {
            builder.AddUserSecrets(typeof(AppConfigurations).GetAssembly(), true);
        }

        var builtConfig = builder.Build();
        new AppAzureKeyVaultConfigurer().Configure(builder, builtConfig);

        return builder.Build();
    }
