KubeOps Operator

The KubeOps.Operator package provides a framework for building Kubernetes operators in .NET. It is built on top of the Kubernetes client libraries for .NET and provides a set of abstractions and utilities for implementing operators that manage custom resources in a Kubernetes cluster.

Getting Started

To get started with the SDK, you can install it from NuGet:

dotnet add package KubeOps.Operator

Once you have installed the package, you can create entities, controllers, finalizers, and more to implement your operator.

All resources must be added to the operator builder in order to be recognized by the SDK and to be used as operator resources. The KubeOps.Generator helps with convenience methods to register everything at once.

You'll need to use the Generic Host to run your operator. However, for a plain operator without webhooks, no ASP.net is required (in contrast to v7).

using KubeOps.Operator.Extensions;

using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

var builder = Host.CreateApplicationBuilder(args);

builder.Logging.SetMinimumLevel(LogLevel.Trace);

builder.Services
    .AddKubernetesOperator()
    .RegisterComponents();

using var host = builder.Build();
await host.RunAsync();

Registering Resources

When using the KubeOps.Generator, you can use the RegisterResources function:

builder.Services
    .AddKubernetesOperator()
    .RegisterComponents();

Otherwise, you can register resources manually:

builder.Services
    .AddKubernetesOperator()
    .AddController<TestController, V1TestEntity>()
    .AddFinalizer<FirstFinalizer, V1TestEntity>("first")
    .AddFinalizer<SecondFinalizer, V1TestEntity>("second")

Entity

To create an entity, you need to implement the IKubernetesObject<V1ObjectMeta> interface. There are convenience classes available to help with initialization, status and spec properties.

[KubernetesEntity(Group = "testing.dev", ApiVersion = "v1", Kind = "TestEntity")]
public class V1TestEntity :
    CustomKubernetesEntity<V1TestEntity.EntitySpec, V1TestEntity.EntityStatus>
{
    public override string ToString()
    => $"Test Entity ({Metadata.Name}): {Spec.Username} ({Spec.Email})";

    public class EntitySpec
    {
        public string Username { get; set; } = string.Empty;

        public string Email { get; set; } = string.Empty;
    }

    public class EntityStatus
    {
        public string Status { get; set; } = string.Empty;
    }
}

Controller

A controller is the element that reconciles a specific entity. You can reconcile your own custom entities or all other entities as long as they are registered within the SDK. For a guide on how to reconcile external entities, refer to the documentation.

A simple controller could look like this:

[EntityRbac(typeof(V1TestEntity), Verbs = RbacVerb.All)]
public class V1TestEntityController : IEntityController<V1TestEntity>
{
    private readonly IKubernetesClient _client;
    private readonly EntityFinalizerAttacher<FinalizerOne, V1TestEntity> _finalizer1;

    public V1TestEntityController(
        IKubernetesClient client,
        EntityFinalizerAttacher<FinalizerOne, V1TestEntity> finalizer1)
    {
        _client = client;
        _finalizer1 = finalizer1;
    }

    public async Task ReconcileAsync(V1TestEntity entity)
    {
        _logger.LogInformation("Reconciling entity {Entity}.", entity);

        entity = await _finalizer1(entity);

        entity.Status.Status = "Reconciling";
        entity = await _client.UpdateStatus(entity);
        entity.Status.Status = "Reconciled";
        await _client.UpdateStatus(entity);
    }
}

This controller attaches a specific finalizer to the entity, updates its status and then saves the entity.

[!CAUTION] It is important to always use the returned values of an entity when using modifying actions of the Kubernetes client. Otherwise, you will receive "HTTP CONFLICT" errors because of the resource version field in the entity.

[!NOTE] Do not update the entity itself in the reconcile loop. It is considered bad practice to update entities while reconciling them. However, the status may be updated. To update entities before they are reconciled (e.g. to ban certain values or change values), use webhooks instead.

Finalizer

A finalizer is an element for asynchronous cleanup in Kubernetes.

It is attached with an EntityFinalizerAttacher and is called when the entity is marked as deleted.

public class FinalizerOne : IEntityFinalizer<V1TestEntity>
{
    public Task FinalizeAsync(V1TestEntity entity)
    {
        return Task.CompletedTask;
    }
}

[!NOTE] The controller (if you overwrote the DeletedAsync method) will receive the notification as soon as all finalizers are removed.

### BREAKING CHANGES

* **web-operator:** The CLI (which broke anyway...) does now
generate everyting together and determines based on the
project if there are webhooks or not. This results in one
config folder instead of separate folders for CRD, RBAC, etc.
With this, conversion webhooks can inject their configuration
into the CRDs. Otherwise, this would be a cumbersome process.
If the need for single topic generation arises again (for example only CRDs),
then these generators can be added again.
* **webhooks:** This overhauls the mutation webhooks.
Use the documentation to see how they work.
It is similar to validation webhooks, but with
changed results.

* **webhooks:** Webhooks are not generated
via the custom command for webhooks, nor are they
automatically installed at runtime. For now, webhook
definitions, certificates, and services are created
at buildtime.
* **webhooks:** This removes the runtime exeuction
of the webhook registrar magic.
* **web-operator:** This overhauls the way
webhooks worked. Webhooks now run
with normal ASP.net ApiControllers.
To use a webhook, refer to the documentation.
Basically, create a subclass of the validation
webhook class and decorate it with the
correct validation attribute. Then, the
webhook will run. Other elements
like automatic install will follow this
preview release.
* **operator:** The targets file contains
other properties than before. Refer to the
documentation for explicit details.
* **operator:** the `IEventManager` is not part
of the operator anymore. To publish events, inject the
`EventPublisher` delegate and use it to publish
events on entities with reason and message.
The name of the events are not base32 encoded but
hex encoded sha512 values now.
* **operator:** controllers do not have
return values anymore. To requeue an entity,
use the `EntityRequeue<_>` delegate. When
an entity is requeued, the reconcile loop
is called after the timeout. If - during this
timeout - the entity is modified or deleted,
the timeout will be cancelled.
* **client:** all calls that were
async before are now sync. There are
async variants of all calls with the
Async suffix.

* **finalizer:** Finalizers are registered
with an identifier now. The identifier is
generated by the KubeOps.Generator when used.
Finalizers are attached via EntityFinalizerAttacher<>
delegates that attach the finalizer to an entity.
* **client:** The IKubernetesClient interface
and implementation now require the TEntity typeparam
instead of each method providing one. The implementation
is instanced with EntityMetadata to allow the operator
to inject the clients for each entity.
* **cli:** This allows the operator
to create a valid selfsigned CA and server
certificate ad-hoc in the cluster when using
webhooks. Instead of generating the certificates
locally and using them as config-map in kustomize,
the operator can run the cli to generate the service
certificate.
* **cli:** The install / uninstall commands
now search for a project or solution file to parse the
CRDs from a solution or a project.
* generator commands
may define a csproj or sln file on where the
entities or other elements are located.
If no file is provided, the current directory
is searched and the command fails if none is found.
* This removes the entity and rbac conversion
from the operator package and extracts them into their own
`KubeOps.Transpiler` package. All static methods there
are used for transpilation of the entities and rbac attributes.
Additional logic for Lease, events and such will reside
in the CLI.
* This removes several features from the
7.x version. Required / missing features will
be added to the v8 again. As for the first
pre release, only the simple watcher and
reconciliation loop is present. No finalizer, events, leadership,
whatsoever is present in the library. The initial pre.0
release is meant to be the base for further implementations.
V8 will - hopefully - contain all required features again.
* The operator does not have commands
and command line executions packaged into the library.
A new dotnet tool is required for CRD generation and
other generators.
* All abstractions are extracted into
a KubeOps.Abstractions package.
* The operator is not required to have
ASP.net as default, it works with a normal console
host application as well.
* `master` is renamed to `main` and
maintenance and release branches are added.
