tanzu content library

The new namespace area will be presented. To upgrade the Kubernetes version we will create a variable and apply it to the cluster using the patch command. The screen that opens allows you to pick a content library if one has already been created. A Persistent Volume Claim of 20GB is instantiated, The WordPress containers are specified (to be pulled/downloaded), Here, we will define a default storage policy . Download the latest version of the VMware HAProxy OVA file from the VMware-HAProxy site. To troubleshoot Prometheus, extract the pods running for Prometheus and verify the log messages from those pods. Note: Logical objects such as Services, DaemonSet will have no impact with this annotation. Since we already have host entry we can test the app with using Access https://foo.bar.com/foo using curl or Web-browser form you cli-vm, Since it is a self-signed certificate, we should accept the browsers security settings before we get to the page, Now let us check other subdomain https://foo.bar.com/bar using curl or Web-browser from theCLI-VM. Note: You should take a backup of current config entries before you delete, and can be restored once the new version has been installed. Extract a configuration file: Prometheus config files are available at ./tkg-extensions-v1.3.1/extensions/monitoring/prometheus/. Deploy App: Deployment & Service objects. In addition, NSX-T networkingenables two further elements: vSphere Pods and a built-in version of theHarbor registry. Read More . These two components will further be used by other tools as part of the TKG Extension package. Scaling out Tanzu Kubernetes Clusters involves changing the number of nodes. The Harbor login page should be seen: We can also test access using docker login. Creation of the namespace. the issue with access Grafana web interface, https://reference.octant.dev/?path=/docs/docs-intro--page#getting-started, https://github.com/vmware-tanzu-experiments/vsphere-with-tanzu-proof-of-concept-samples, 2(a) NSX Advanced Load Balancer Configuration, https://kb.vmware.com/s/article/82049?lang=en_US, https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-489A842E-1A74-4A94-BC7F-354BDB780751.html, Download the TKG Extensions v1.3.1 Bundle, Option 1: Patch or Edit the TKC manifest to add a default StorageClass. Similar to TKG, we need to setup a content library to pull from. Part of the prep work prior to Tanzu Kubernetes deployment in your environment, is to configure a storage policy or policies for Tanzu workloads. Use a yaml validator, such as yamlint to make sure the format is correct. After you click next, youll need to accept the SSL thumbprint of the certificate by clicking the YES button. For the Tanzu Kubernetes Clusters, the monitor tab also provides specific insights to the particular TKG Cluster. Fluentbit configuration can be updated in the fluent-bit-data-values.yaml and re-apply the updated config file. If the TKG Demo Appliance is being used, Octant is already installed. You can notice the connection details has already been filled in by default. Fluent Bit is an open-source Log Processor and Forwarder which allows you to collect any data like metrics and logs from different sources, enrich them with filters, and send them to multiple destinations. contour.config.timeouts.requestTimeout:Timout for an entire ingress request. Then we show how the devops user can make use of this to create another TKG cluster. See Configure a vSphere Namespace for Tanzu Kubernetes releases. Configure Supervisor Cluster Namespace(s) with RBAC, Configure Supervisor Cluster Namespace(s) Storage Policy, Configure Supervisor Cluster Namespace(s) with Resource Limitations, Monitor Namespaces, and K8s Objects resource utilization (vCenter). The following URI references are served by Prometheus server Access Prometheus GUI using https://prometheus.cluster.test/, Example - Metrics based on the node_memory_MemAvailable_bytes. Envoy EXTERNAL_IP, Verify Ingress object and envoy LB-IP to access that ingress. Like other immutable patterns, to upgrade the Fluentbit, you need to delete the current version of FluentBit resources and deploy the new version. can then be explored inside of the network provider. Test the instance by using a browser to navigate to the IP address of the CentOS VM. Antrea CNI, VMware recommended, default CNI solution, delivered out-of-box with Tanzu Kubernetes Clusters. Along with the core Kubernetes, the DevOps team needs additional platform tools for connecting, monitoring, and accessing container workloads running on the K8S cluster. In this model, NSX-T SDN will serve all the networking needs for the stack. Businesses are embracing an API-first approach to application development and using APIs and microservices to create modern . Note: No need to change any default values unless the cluster doesnt have a default storage class (or) one wishes to use the specific storage class for Prometheus & AlertManager. This is where permissions, storage policies and other options can be set. Navigate to Cluster>Monitor>Namespaces>Overview. Create Contour config file by copying from the template file given in the package, Update the data value file: Ensure we have the right version of the Envoy package. Stay up to date on vSphere patching and updates with resources for planning, preparation, and delivery with VMware's comprehensive lifecycle management tools. Together with Antrea as a CNI and NSX-T as a network stack, customers can benefit from enterprise-grade network policy management and a single interface for managing all network policies for VMs, K8S Nodes, Container workloads, cross-cluster & cross namespace network policies. It is important to note that the user/group to be added to this namespace should have already been created ahead of time. Navigating to Hosts and Clusters > Namespaces > [namespace] will give you a view of the information cards. In this guide we detail the two networking options available invSphere with Tanzu, namely vSphere or NSX-T networking. TKG Content Library. Below, we will briefly run through the steps to configure the NSX ALB. Under the compute tab for the namespace, the resources for Tanzu Kubernetes as well as Virtual Machines display key information about the environment such as version, IP address, phase, etc. For information, see Monitor VMs in the vSphere Client. If you want more background on VMware Tanzu, you can read more about it here. This URL is a publicly accessible repository which has the virtual machines templates which are configured for Tanzu Kubernetes Grid. For more information on private registry support, see: https://core.vmware.com/blog/vsphere-tanzu-private-registry-support. Once the appliance has been deployed and powered on, login to the UI using the supplied management IP/FQDN. In this example, we will use the VM Service feature to deploy a VM as a devops user and then install a Harbor registry on it. Ingress can be HTTP, HTTPS, and sending all the traffic to one service or splitting the traffic between two services. Roles: fluent-bit-extension-role, fluent-bit-extension-cluster-role, Instance_name: Mandatory but arbitrary; Appears in the logs, Cluster_name: name of the target TKC / guest cluster. Looking at our Harbor UI, under Projects > library > myrepo we can see that the image has been pushed. There are several methods to upgrading the vCenter appliance. pane to monitor the status of the update. Cluster Provision will take a few minutes. Finally, we will use that Harbor instance as a private registry for a TKG cluster. We are taking a closer look at the impact of Kubernetes on business and operational success. You can validate the object creation as following. Select the appropriate storage policy to add to the namespace: Resource limitations such as CPU, memory, and storage can be tied to a namespace. Make a host entry in the CLI-VM (or) add a DNS A record in your DNS server with the Envoys EXTERNAL_IP mapping to the grafana.system.tanzu is. Below well focus on the networking, i.e. Then we apply the patch to the existing tkc that we are targeting. The update should take effect in 5 minutes or less. The version parameter should then be changed to the version of Kubernetes we want to upgrade to. For more information, see the Release Notes. We can inspect the current version of our TKG cluster: Looking at our available versions, we can see that we have versions from 1.16.12 - 1.20.2available. Select Menu > Content Libraries > . Method 2: Use Kubectl edit to directly edit this YAML file. CNI makes a clear separation between container vs infra network. Since we dont have an external DNS to resolve our FQDN yet, for now lets add a host entry for the app FQDN so that we can access the app using the http with FQDN name directly. You can increase the number of control-plane VMs, Worker VMs or both at the same time. You can use the remaining default values as it is. No firewall rules exists between these (that's for a later post). Deployment(s): Prometheus creates 4 Deployments objects, DaemonSet(s): Prometheus creates 2 DaemonSet objects, Replace with users choice base64 values, Sample app with Layer7 Ingress (HTTP & HTTPS), https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/. Then update the OS to use the new certificate (a reboot may be needed). Contour as a Control plane: Contour is the control plane for the Contour ingress, which synchronizes user ingress requests with the Envoy proxy. Accessing default data source (Prometheus), Grafana from TKG Extensions comes with a default data source Prometheus running on the same TKC/Guest Cluster. Product information and getting started, Section 2: App Deployment & Testing Then, without making any changes, click Actions to trust the new cert. Once Cluster is up, you can check the status. Well call this manifest bb.yaml: This should pull very quickly, and we can get and describe the pod: Further examples of workloads on Tanzu Kubernetes Clusters can be found in the official documentation: https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-E217C538-2241-4FD9-9D67-6A54E97CA800.html. We also have the ability, from vSphere 7 Update 2a, to use private registries for TKG clusters. For more information, please refer to the official documentation. Once the VCF environment with SDDC manager has been deployed (see https://docs.vmware.com/en/VMware-Cloud-Foundation/index.html for more details), Workload Management can be enabled. Fluent bit supports tens of outputs including Elastic-search, HTTP, Kafka, Splunk, Syslog, etc. To create a Subscribed Content Library using the vSphere Client: In a web browser, log in to the workload domain vCenter Server by using the vSphere Client (https://<vcenter_server_fqdn>/ui). Select one or more Supervisor Clusters to apply the update to. Explore our web page for comprehensive resources on deploying and migrating VMware Cloud Foundation, including interactive demos and installation guides. Add the certificate from the previous step: Thus, any new TKG clusters created will automatically trust the registry. Webinar. (HaProxy will serve the IP from the workload subnet): Once deployed, we can list the external IP assigned to it using the get service command: Therefore, opening a browser to the External-IP on port 8080, i.e. For more information on the VM service, see: https://core.vmware.com/blog/introducing-virtual-machine-provisioning-kubernetes-vm-service. Login to this new TKG cluster. Jun 1 - State of Kubernetes 2023: Solving Kubernetes Challenges in 2023. This can then be combined with the login command for quicker/automated logins, for example (here we have also installed the certificates, thus we have a shorter login command): It is a good idea to get any manifest files checked for correct syntax, etc. Developer productivity 60 percent and IT efficiency 64 percent were widely cited as business benefits. Streamline IT operations and accelerate your digital transformation with this turnkey solution. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. Ensure that an TKC RBAC profile has been applied to the cluster (see the previous section on creating TKGclusters and granting developer access), Download the two manifest files for mySQL and Wordpress using, Follow one of the two options below to satisfy the storage policy requirement. Unzip this file and place the contents in the system path (such as /usr/local/bin). Select all available classes and add them to the Namespace: For more details on the sizing see: https://via.vmw.com/tanzu_vm_classes. Supervisor Namespaces providelogical segmentation between sets of resources and permissions. ^ HaProxy only. Now we know the pod details contour and envoy, we can extract the logs for troubleshooting purpose. Realizing the value of Kubernetes can be an elusive endeavor. Resources on patching and upgrading your VMware Cloud Foundation deployments to gain new features and ensure security and reliability. Main steps: Configuration Storege Policy and Tags. [] 11 Creating a Content Library for Tanzu Kubernetes Clusters [], Your email address will not be published. In addition to the required network features like K8S POD & Service network, network policies, Antrea provides the most advanced network policies and out-of-box integration with NSX-T. Sausages and Cycling - Coding with AI/LLMs, microservices vs. monoliths, How to change mainframe apps into microservices, modernizing mainframe What Is an Application Programming Interface (API)? We can then see the Virtual Machine images available (we exclude the TKG images for our purposes): First, we create a file named centos-user-data that captures the user, password and any customisation parameters. Contour deploys both Contour control plane & Envoy data plane. Customers can create a Tanzu Kubernetes Releases (TKR) content library by either subscribing to VMware's online repository or by creating a local content library and manually importing the images, which can be useful for air-gapped or non-internet accessible environments. Kapp controller: Reconciles the TKGExtension components. Here we create tks.yaml. However, vSphere with Tanzu also allows bringing your Load balancer, for example, HAProxy. Note: These pod names are important to troubleshoot FluentBit in case if any issues. If necessary, use the kubectl config use-context command to switch to the correct supervisor namespace. Notify me of follow-up comments by email. Click on. Note that under the Configure tab, it is also possible to limit objects such as Replica Sets, Persistent Volume Claims (PVC), and network services among others. First change context to the namespace that the TKG cluster resides. This will be done one VM at a time, starting with the control-plane, until they are all completed. (An option to deploy with three networks, i.e. Click on the Prometheus row marked as default. Option 2: Edit the app manifest files to explicitly add the storage class: Prepare the deployed VM and Install Harbor, Configure the TKG Service to Trust the Deployed Repository, Delete Supervisor Cluster and Confirm Resources are Released, Lifecycle management including Day0, Day1, and Day2 operations, Tanzu Kubernetes Grid Service aka vSphere With Tanzu, vSphere Namespace, newly introduced in vSphere 7, to create multi-tenancy. Extract Contour logs by using the pod name we listed before, Extract Envoy logs by using the pod name we listed before. Update the YAML file and re-apply secret & app YAML files, Ref: Supported Prometheus Configuration parameters can be found at VMware official Documents. This is needed to tell the controller to use the Frontend network to allocate VIPs via IPAM. vSphere Distributed Switch (defined and managed by vCenter), Setting up the network stack (will explore all three options for network stack), Creating SBPM policy and assignment them to Namespaces, Setting up a standalone Harbor Image repository, Creating a Tanzu Kubernetes Cluster (TKC aka guest cluster), Installing Tanzu Extensions (CertManager, Contour, Fluentbit, Prometheus, Grafana), Kapp-controller & CertManager (Pre-requisite, common tools). Note: VMware recommends using NSX-T as a network choice, which enables the complete enterprise-grade features all-in-one network solution. In this example, we describe how to do this with standard (block) vSAN volumes. Visually, this can be seen in vCenter: We change context to the Supervisor Namespace that contains the TKG cluster that we would like to destroy: Double-check the namespace is the correct one; a star next to the name indicates the currently selected context: See which TKG cluster(s) reside in the namespace: Prior to deletion, conduct a search for the TKG cluster within the vCenter search field to see all related objects: Finally, to the delete TKG cluster, in this case with the name tkgcluster1: vCenter will have tasks regarding the deletion of the TKGcluster and all related objects: From vCenter, we can see that there are no more resources relating to the TKG cluster: To delete namespaces from the UI, navigate to Menu > Workload Management > Namespaces. VMware Cloud Foundation simplifies cloud infrastructure deployment and management, providing a complete set of software-defined services for compute, storage, networking, and security. Clicking on Finish will start the supervisor deployment process: For an interactive guide of the steps above, visit: https://core.vmware.com/delivering-developer-ready-infrastructure#step_by_step_guide_to_deploying_developer_ready_infrastructure_on_cloud_foundation_isim_based_demos. Give the Content Library a name and any notes that you may have. For permissions, leave Write selected, as this will allow for easier deployment and automation between ALB and vCenter. In vSphere 7 update 2a there is a further requirement to add a VM class. Note, in a production environment, a separate 'data network' for the SEs may be desired. This is hosted on GitHub: https://github.com/haproxytech/vmware-haproxy. Navigate to left side menu panel, click on the settings->Configuration->Data Sources. Webinar. First change context to the namespace that the TKG cluster resides. VMware provides powerful solutions for storing, protecting, and recovering data in the event of a disaster. Before use ingress in a workload, let's verify the status of Contour app objects. The fastest way to get started with Kubernetes workloads is with vSphere with Tanzu. N.B. with an additional Frontend network is also available but is beyond the scope of this guide). With Tanzu Application Platform, you can realize economies of scale from your multi-cloud Kubernetes platform. After a few minutes, you will see that status will change from updating to running, at which point you can verify the cluster by running: In order to delete a Tanzu Kubernetes Cluster, first switch to the Supervisor Namespace where the cluster is located. Full details for the Prometheus app configuration can be availed here, Lets check for Deployments & DaemonSet object creation status, Lets check for the PVC objects created by Prometheus & AlertManager, Create a Host entry on your CLI-VM to access Prometheus GUI, Access Prometheus GUI from the CLI-VM web browser. Check that the validation succeeds. We then create a simple manifest that will pull the container. Let's verify the objects we just created. FQDN grafana.system.tanzu is being served by Envoys EXTERNAL_IP (Contour ingress data plane). A: Referring Secret object we created earlier in our https-ingress object. Deploying load balancer - HAProxy. You can use other subscription URLs with content libraries, but for Tanzu you should use this URL to get the appropriate templates. Click on Create Certificate green box. Lastly, go back to the supervisor cluster and click the edit button next to content library again. Note: Repeat the above two steps (updating config & creating a secret) per destination type of your choice like Elasticsearch, HTTP, Kafka, Splunk etc. Select your content library and click OK. In vCenter, configure a vDS with at least two port groups for Management and Workload Network. Specify v1.17.3_vmware.1 in the configuration as shown. [EMEA] Introduction to the new Greenplum Database library for Python. Click on Add Permissions and fill in the necessary fields. For information, see. Leave SDN Integration set to None. We will further use this EXTERNAL-IP for all ingress(layer7) communications. On the VM Service card click on Add VM Class to add VM class definitions to the Namespace: This will bring up a window to enable you to add the relevant VM classes (or to create your own). VMware Tanzu distributes Kubernetes software versions as Tanzu Kubernetes releases. A Github repository with code samples to accompany this document is available at: https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-AC9A7044-6117-46BC-9950-5367813CD5C1.html. Confirm that this is the same image we have tagged above. Select the appropriate storage policies for the control plane, ephemeral disks and image cache: Click on Next to show the review window. Config values (input & output connection details) are independent from Fluentbit resources, hence you can re-use the current config values. This can be monitored using the get and describe verbs on the tkc noun: For more verbose output and to watch the cluster being built out, select yaml as the output with the -w switch: In vCenter, we can see the TKC VMs being created (as per the manifest) within the supervisor namespace: Once provisioned, we should be able to see the created VMs in the namespace: Once the TKC has been created, login to it by using kubectl vsphere with the following options: Login using the user/credentials assigned to the namespace.
