Microsoft.Extensions.Diagnostics.Probes

Answers Kubernetes liveness, startup, and readiness TCP probes based on the results from the Health Checks service.

Install the package

From the command-line:

dotnet add package Microsoft.Extensions.Diagnostics.Probes

Or directly in the C# project file:

<ItemGroup>
  <PackageReference Include="Microsoft.Extensions.Diagnostics.Probes" Version="[CURRENTVERSION]" />
</ItemGroup>

Usage Example

The health check endpoints can be registered and configured with the following methods:

public static IServiceCollection AddKubernetesProbes(this IServiceCollection services)
public static IServiceCollection AddKubernetesProbes(this IServiceCollection services, IConfigurationSection section)
public static IServiceCollection AddKubernetesProbes(this IServiceCollection services, Action<KubernetesProbesOptions> configure)

Each type of probe handler can have its details configured separately.

services.AddKubernetesProbes(options =>
{
    options.LivenessProbe.TcpPort = 2305;
    options.StartupProbe.TcpPort = 2306;
    options.ReadinessProbe.TcpPort = 2307;
})

The HealthAssessmentPeriod property defines how often the health-checks are assessed. By default 30 seconds.

Each probe can also specify Func<HealthCheckRegistration, bool>? FilterChecks to customize which health checks are run.
