VMware Event Broker on Kubernetes with Knative Functions – Part 2: Deployment and Configuration

In the first part of this series, we discussed the basics of VMware Event Broker and its integration with Knative functions on Kubernetes. In this second part, we will dive deeper into the deployment and configuration of the event broker and Knative functions. We will also explore some advanced features and use cases of the combination of VMware Event Broker and Knative functions.

Deploying VMware Event Broker on Kubernetes

—————————————–

To deploy VMware Event Broker on Kubernetes, we can use the Helm chart provided by the VEBA team. We will first need to register the Helm chart registry and get the metadata locally. The support of Knative with Helm VMware event router deployment method is only supported in chart version >= v0.6.2, so ensure that this version is available.

We can create a specific namespace for this purpose, such as `vmware-fn`, but we can also reuse the `vmware-fn` namespace or any other existing one. We will need to specify the broker name and namespace according to our configuration.

Here is an example of the `override.yaml` file we will use:

“`yaml

apiVersion: v1

kind: EventBroker

metadata:

name: vmware-event-broker

spec:

brokerName: vmware-event-broker

namespace: vmware-fn

“`

We can now deploy the Helm chart using the following command:

“`

helm install –name vmware-event-broker –namespace vmware-fn

https://vmware.github.io/knative-event-router/versions/main/helm/v0.6.2/vmware-event-broker.helm

“`

Once the deployment is complete, we can check the status of the deployment:

“`

kubectl get deployments

“`

We can also use the `kubectl describe` command to view more detailed information about the deployment:

“`

kubectl describe deployment vmware-event-broker

“`

Configuring Knative Functions

—————————-

To configure Knative functions, we will need to create a `function.yaml` file for each function we want to deploy. Here is an example of a `function.yaml` file for an echo function that will receive cloud events from the VMware Event Broker:

“`yaml

apiVersion: serving.knative.dev/v1alpha1

kind: Function

metadata:

name: kn-echo

spec:

handler: github.com/embano1/kn-echo/main.handler

eventTypes:

– cloud

labels:

app: kn-echo

“`

We can create the function by running the following command:

“`

kubectl apply -f function.yaml

“`

We can check the status of the function deployment:

“`

kubectl get functions

“`

Performing Tasks Based on Event Routing Setup

———————————————-

Now that we have deployed the VMware Event Broker and Knative functions, we can perform tasks based on the event routing setup. One useful task is to echo cloud events occurring in the target vCenter server. The VEBA team provides multiple echo samples (python or PowerShell-based), but we will use the python-based one provided by @embano1/kn-echo.

To check what was created, we can run the following command:

“`

kubectl get deployments

“`

We can also use the `kubectl describe` command to view more detailed information about the deployment:

“`

kubectl describe deployment kn-echo

“`

Autoscaling with Knative Serving

——————————-

One of the benefits of using Knative functions is the ability to autoscale based on incoming events. We can set the minimum and maximum scale settings using the `autoscaling` field in the `function.yaml` file. For example, here is an updated version of the `function.yaml` file with autoscaling settings:

“`yaml

apiVersion: serving.knative.dev/v1alpha1

kind: Function

metadata:

name: kn-echo

spec:

handler: github.com/embano1/kn-echo/main.handler

eventTypes:

– cloud

labels:

app: kn-echo

autoscaling:

minScale: 1

maxScale: 5

“`

In this example, the function will be scaled to a minimum of 1 instance and a maximum of 5 instances.

Advanced Features and Use Cases

——————————-

VMware Event Broker and Knative functions offer a wide range of advanced features and use cases, such as:

* Using the VMware Event Broker with other cloud providers, such as AWS or Azure.

* Integrating with other Kubernetes components, such as ConfigMaps or Secrets.

* Using Knative functions with other event sources, such as HTTP or gRPC.

* Implementing custom handlers for specific event types.

* Using the VMware Event Broker with other Knative functions, such as the `kn-http` function for receiving HTTP requests.

Conclusion

———-

In conclusion, VMware Event Broker and Knative functions offer a powerful combination for building cloud-native applications on Kubernetes. By integrating the VMware Event Broker with Knative functions, we can leverage the benefits of both technologies to build scalable, reliable, and secure applications that can respond to events in real-time.

We hope this series of blog posts has provided a comprehensive overview of the combination of VMware Event Broker and Knative functions on Kubernetes. Whether you are a cloud builder or a Kubernetes enthusiast, we encourage you to explore these technologies further and see how they can help you build the next generation of cloud-native applications.

As a VMware expert, I will continue to discuss the topic of Host Failure Detection in vSphere HA, focusing on datastore heartbeating. In my previous article, I explained how vSphere HA works and the different types of host failures that can occur. In this article, I will delve deeper into the topic of datastore heartbeating and its importance in ensuring the high availability of your virtual infrastructure.

Datastore Heartbeating: What is it and Why is it Important?

Datastore heartbeating is a feature in vSphere HA that allows you to monitor the health of your datastores and detect any issues before they become critical. When you enable datastore heartbeating, vSphere HA will periodically send a heartbeat signal to the datastores to check their status. If the datastore does not respond to the heartbeat signal within a certain time frame, vSphere HA will consider it failed and take appropriate action, such as failing over to a standby host or restarting the affected virtual machines.

The importance of datastore heartbeating lies in its ability to detect issues before they become critical. By regularly monitoring the health of your datastores, you can identify potential problems early on and take corrective action before they impact your virtual infrastructure. This feature is especially important in vSphere HA clusters with multiple datastores, as it allows you to monitor the health of each datastore individually and take appropriate action if one of them fails.

How to Configure Datastore Heartbeating in vSphere HA?

Configuring datastore heartbeating in vSphere HA is relatively straightforward. Here are the steps you need to follow:

1. Open the vSphere HA configuration page by clicking on the “Configure” button in the vSphere HA window.

2. In the “Clusters” section, click on the cluster for which you want to configure datastore heartbeating.

3. Click on the “Edit” button next to the “Datastore Heartbeating” section.

4. Select the datastores for which you want to enable heartbeating. You can choose individual datastores or select all of them at once.

5. Set the “Heartbeat interval” to the desired time frame (in seconds) within which vSphere HA will send a heartbeat signal to the selected datastores.

6. Click “OK” to save your changes.

Best Practices for Datastore Heartbeating

While configuring datastore heartbeating is relatively straightforward, there are some best practices that you should follow to ensure the highest availability of your virtual infrastructure:

1. Monitor your datastores regularly: It’s essential to monitor the health of your datastores regularly, even if you have enabled datastore heartbeating. This will allow you to detect any issues early on and take corrective action before they impact your virtual infrastructure.

2. Use a short heartbeat interval: A shorter heartbeat interval will allow you to detect issues more quickly, but it may also increase the load on your datastores. You should strike a balance between detection speed and resource utilization.

3. Use multiple datastores: Using multiple datastores in your vSphere HA cluster can help ensure high availability by providing redundant storage for your virtual machines.

4. Test your heartbeating configuration: Before you start using datastore heartbeating in your production environment, it’s essential to test the configuration thoroughly to ensure that it works as expected. You can use the vSphere HA testing tools to verify that your configuration is correct and functional.

Conclusion

In conclusion, datastore heartbeating is a crucial feature in vSphere HA that allows you to monitor the health of your datastores and detect any issues before they become critical. By following the best practices outlined above, you can ensure the highest availability of your virtual infrastructure and quickly detect and resolve any issues that may arise. Remember to regularly monitor your datastores, use a short heartbeat interval, use multiple datastores, and test your heartbeating configuration thoroughly before deploying it in your production environment.

My Journey from Infrastructure Admin to Cloud Architect: The Power of vSAN in Data Evacuation

As an infrastructure admin, I have always been focused on ensuring the smooth operation of my company’s IT infrastructure. However, as I transitioned into a cloud architect role, I realized that there was so much more to consider when it comes to data evacuation and vSAN. In this blog post, I will share my journey from an infrastructure admin to a cloud architect and how vSAN helped me along the way.

The Challenge of Data Evacuation

One of the biggest challenges in data evacuation is determining how quickly data can be evacuated from a disk. The answer, as you might expect, is “it depends.” The performance of the disk, network, and current I/O load of the cluster all play a role in determining how quickly data can be evacuated. As an infrastructure admin, I had always been focused on ensuring that my company’s IT infrastructure was running smoothly, but as a cloud architect, I needed to consider a much broader range of factors when it comes to data evacuation.

vSAN to the Rescue

That’s where vSAN comes in. With vSAN, I can easily evacuate data from my disk and ensure that my company’s IT infrastructure is running smoothly. vSAN provides a range of tools to help me with this process, including resync dashboards, resync throttling, fairness scheduler, performance dashboards, pre-checks, and esxtop.

Resync Dashboards

One of the most valuable features of vSAN is its resync dashboards. These dashboards provide me with a clear view of the status of my data evacuation process, including the current state of each object, the progress of each object, and any errors or issues that may arise during the evacuation process.

Resync Throttling

Another useful feature of vSAN is resync throttling. This feature allows me to manually control the bandwidth used for data evacuation, ensuring that my company’s IT infrastructure remains stable and responsive even during periods of high usage.

Fairness Scheduler

One of the most important factors in data evacuation is ensuring that frontend I/O (VM I/O) and backend I/O (policy changes, evacuations, rebalancing, repairs) are balanced. vSAN’s fairness scheduler helps me to achieve this goal by keeping a healthy balance between these two types of I/O traffic. This ensures that my company’s IT infrastructure remains stable and responsive even during periods of high usage.

Performance Dashboards

In addition to resync dashboards, vSAN also provides performance dashboards that allow me to monitor the status of my data evacuation process in real-time. These dashboards provide a detailed view of frontend and backend traffic, allowing me to quickly identify any issues or bottlenecks that may arise during the evacuation process.

Pre-Checks

Another useful feature of vSAN is pre-checks. This feature allows me to determine which components of an object can be potentially affected by the disk evacuation process. By selecting the preferred ‘vSAN data migration’ option, I can ensure that my company’s IT infrastructure remains accessible even during periods of high usage.

Esxtop

Finally, vSAN provides esxtop, a powerful tool that allows me to monitor near real-time vSAN stats per host. This feature is particularly useful when it comes to observing rebuild traffic, as it allows me to quickly identify any issues or bottlenecks that may arise during the evacuation process.

Conclusion

In conclusion, my journey from infrastructure admin to cloud architect has taught me the importance of considering a range of factors when it comes to data evacuation. vSAN has been an invaluable tool in this process, providing a range of features and tools that allow me to easily evacuate data from my disk and ensure that my company’s IT infrastructure remains stable and responsive even during periods of high usage.

NSX Certificate Exchange of the NSX Manager: Understanding the Process and Best Practices

As a VMware NSX expert and VCDX #181, I often get asked about the certificate exchange process for the NSX Manager. In this blog post, we’ll dive into the details of the certificate exchange process, why it’s important, and best practices to ensure a smooth and secure deployment.

CSR Request Creation with OPENSSL

To start the certificate exchange process, we need to create a Certificate Signing Request (CSR) using OPENSSL. This is a crucial step in the process as it generates a request that will be sent to the Certificate Authority (CA) for the issuance of a digital certificate.

When creating the CSR, it’s important to use the appropriate domain name and common name (CN) for the NSX Manager. The CN should match the FQDN of the NSX Manager, and the domain name should be the fully qualified domain name (FQDN) of the organization or entity that will be using the certificate.

Key Export

As mentioned earlier, it’s important to export the key along with the CSR request. This is because the CA will use the key to sign the certificate, and without the key, the certificate cannot be validated.

Individual Certificates vs. SAN Certificate

There are two approaches to obtaining certificates for the NSX Manager: individual certificates for each of the four nodes (VIP and three manager nodes), or a SAN (Subject Alternative Names) certificate that covers all four nodes.

While both approaches have their advantages and disadvantages, I generally recommend using individual certificates for each node. This is because individual certificates provide better validation and security for each node, as the certificate is specifically issued for that node’s FQDN.

On the other hand, a SAN certificate can be more convenient to manage, as it covers all four nodes with a single certificate. However, this approach can also introduce additional complexity and security risks if the certificate is not properly configured and managed.

Certificate Creation and Installation

Once the CSR request is created and the certificate is issued by the CA, we need to install the certificate on each of the NSX Manager nodes. This involves copying the certificate and private key to the appropriate locations on each node, and configuring the nodes to use the certificates for authentication and encryption.

Best Practices for Certificate Exchange

Here are some best practices to keep in mind when exchanging certificates for the NSX Manager:

1. Use a trusted CA: Make sure to use a trusted CA that is recognized by your organization and the industry. This will ensure that the certificate is valid and can be trusted by all parties involved.

2. Use a secure communication channel: When exchanging certificates, it’s important to use a secure communication channel, such as HTTPS or SSH. This will ensure that the exchange is secure and cannot be intercepted or tampered with.

3. Validate the certificate: Before installing the certificate on any node, make sure to validate it using a trusted certificate authority. This will ensure that the certificate is valid and can be trusted by all parties involved.

4. Keep the private key secure: The private key is a critical component of the certificate exchange process, as it allows you to decrypt and authenticate with the certificate. Make sure to keep the private key secure and do not share it with anyone unless absolutely necessary.

5. Monitor the certificate status: Finally, make sure to monitor the certificate status regularly to ensure that it is still valid and has not been revoked or expired. This can be done using tools such as OpenSSL or certutil.
