Custom Docker Feature Configuration

SanteDB typically uses the configuration file and the IFeature mechanism for advanced configurations. However, SanteDB also runs within Docker and Kubernetes environments. These are configured using the IDockerFeature interface.

For example, to expose FOO as a feature on the SDB_FEATURE and provide a parameter called BAR which is leveraging the application settings part of the configuration file:

/// <summary>
/// A sample docker feature
/// </summary>
public class FooDockerFeature : IDockerFeature
{

    public const string FooBarSetting = "BAR";

    /// <summary>
    /// This is the feature ID on the SDB_FEATURE
    /// </summary>
    public string Id => "FOO";

    /// <summary>
    /// Settings for the foobar feature
    /// </summary>
    public IEnumerable<string> Settings => new String[] { FooBarSetting };

    /// <summary>
    /// Configure this service
    /// </summary>
    public void Configure(SanteDBConfiguration configuration, IDictionary<string, string> settings)
    {

        // We can fetch the settings for our feature (parsed from docker 
        // environment) with the settings parameter
        if (!settings.TryGetValue(FooBarSetting, out string fooBar))
        {
            fooBar = "Hello World!";
        }
        
        // Set my settings
        configuration.AddSection(new FooBarConfigurationSection() {
            Bar = fooBar
        });
        
        // Add foobar services
        var serviceConfiguration = configuration.GetSection<ApplicationServiceContextConfigurationSection>().ServiceProviders;
        serviceConfiguration.Add(new TypeReferenceConfiguration(typeof(FooBarService)));
    }
}
