scheduler to place You can take advantage of the fact that the seed nodes are labeled to find their addresses. We configure the cluster using an auto scaling group (ASG) that maintains a set of nodes appropriately sized for our workloads. Enable Cloud Resource Manager API. To confirm that the default configuration is still in effect, navigate to http://:7000/cluster-config and expect to see the following: Run the following command to make the replica placement region-aware or cluster-aware so that one replica is placed on each region or cluster: To view the new configuration, navigate to http://:7000/cluster-config and expect to see the following: To connect and use the YSQL Shell (ysqlsh), run the following command: To connect and use the YCQL Shell (ycqlsh), run the following command: Follow the instructions provided in All control plane components For example: Typically youll find that the system_auth, system_traces, and system_distributed keyspaces use NetworkTopologyStrategy, as well as data_endpoint_auth if youve enabled Stargate. Now we will execute the same terraform commands to initialize, plan and apply our script to the cloud.Once finished we should be able to see the changes in our Google Cloud Account. This is more helpful if our clients are from multiple locations across the globe. If you worked through the first blog, many of the steps will be familiar. Now, follow the following steps for configuring the Kubernetes slave. All of the actions below can be applied to any number of Member Clusters. The focus of the talk in this webinar about how to deploy a multi-region kubernetes cluster is that you can spin up a multi-region application, such as CockroachDB, on two different Kubernetes clusters, (one in each region) and have them all communicate with each other. It will be easier to manage our K8ssandra installs in different clusters if we use the same administrator credentials in each datacenter. The next step is to create a K8ssandra deployment for the first datacenter. As soon as gcloud container clusters create returns, you will find a kubeconfig in the current directory. All our Kubernetes deployment yaml files are now created. Login to this instance by clicking the SSH button in the GCP console. It uses something known as Network Endpoint Groups to route traffic from the LB directly to the Pods.. This is the second in a series of posts examining patterns for using K8ssandra to create Cassandra clusters with different deployment topologies. Let's allow the following APIs. off-line at the same time. Application Pods (regional) A Kubernetes deployment object is used to create multiple replicas of a pod (ReplicaSet). For optimal performance, ensure you have set the appropriate. Nowadays, most applications are using Kubernetes for their deployments. can complete enough to bring at least one node into service. If the api is not enabled in your project then you will see the below prompt: VPC is . It essentially completes the same steps that the cloud-controller would, but as it is external to any cluster it can coordinate between them. admission controller As an example, in preparing this post, I followed the instructions on the K8ssandra Google Kubernetes Engine (GKE) installation docs to create a GKE cluster in the us-west4 region. Major cloud providers define a region as a set of failure zones (also called availability zones) that provide a consistent set of features: within a . Enable GKE hub API. Now that we have our networking solution ready, we will create our primary Kubernetes cluster. Back to the cluster. A multi-cluster multi-tenant model showing Team Athena Slice and Team Zeus Slice. or Log in to your CockroachDB Cloud account. On the "Cluster basics" page, set the name of . Limitations By. On the Overview page, select Create Cluster. Access the YB-Master Admin UI for the cluster at http://:7000 where external-ip refers to one of the yb-master-ui services. Replicate storage across multiple regions. also replicate this across all the failure zones you selected. 1. In my previous story we configured KEDA on Kubernetes. Service and gke-primary/main.tf Sample Application Deployment Kubernetes YAML Files Generation. or use a tool such as the Cluster API to This reference implementation will go over some design decisions from the baseline to detail them as a well as incorporate some new recommended infrastructure options for a multi-cluster (and multi-region) architecture. Time to configure our secondary Kubernetes cluster.Lets create another directory in the k8s-multi-region-cluster called gke-secondary and copy all three files from gke-primary here. Well also dive into more details on networking and DNS configuration. something to consider. Federation takes the idea of Multi-Cluster deployments a bit further. This will initialize your gcloud cli, you will need to login into your google cloud account and also set other details like region, project. gcloud compute networks create vpc-k8s. global access. Haven't really heard of linode. without explicitly defining which availability zones are in use for Why do we really need to setup a multi region cluster ? Note: for the purpose of this exercise, youll create GKE clusters in two separate regions, under the same Google Cloud project. are only placed into the same zone as that volume. elements. Rebuild needs to be run on each node in the new datacenter, for example: Repeat for the other nodes multi-region-dc2-rack2-sts-0 and multi-region-dc2-rack3-sts-0. It will then deploy the application, along with the AWS App Mesh configuration, to your cluster in a new howto-k8s-multi-region namespace.. They are more lightweight and flexible than virtual machines. We help developers learn and grow by keeping them up with what matters. Now that we have our terraform script to create VPC and two subnets, we should try running it and check if the infrastructure is created in our account.Execute following commands in the vpc directory, and also check if everything is running good (you might need to enable some APIs on google cloud, you will get error message if this is needed) : We should be able to see the changes in our Google Cloud Account. Create a new GCP project Create a new AWS account Add Kubernetes clusters New Kubernetes cluster on GCP or Azure New Kubernetes cluster on AWS Deploy support components Configure and deploy the support chart Setup grafana dashboards Register the cluster's Prometheus server with the central Grafana The overall design would like something like below diagram. You can deploy a single multi-region YugabyteDB cluster that spans three The reason you get response from only one region mostly is because Google Internal Load Balancer used for this setup forwards the requests to the closest location.More details of this setup can be found here. Google provide a multi cluster ingress tool called kubemci , which can be used to automate the setup of a global load balancer from a Kubernetes Ingress resource. Kubernetes cluster is generally deployed on the Clouds like AWS or GCP or Azure, etc. 2022 Before we begin In Rack topology, Why Affinity Rules are preferred over TopologySpreadConstraint? In this way, Kubernetes clusters allow for applications to be more easily developed, moved and managed. This spreading helps Medusa-restore start on every restart of cassandra DC. We just finished setting up Multi Region Kubernetes Cluster on Google Kubernetes Engine (GKE). You can see that the slave node from Azure is connected successfully and is ready to use. An AKS cluster is deployed into a single region. Love podcasts or audiobooks? ; 3. To do this youll pick a Cassandra node to execute the nodetool status command against. An open-source command-line tool that can be used to provide an infrastructure on many different platforms and services such as IBM, AWS, GCP, Azure, OpenStack, VMware, and more. one zone also impairs services in another zone. You can find in-depth information about etcd in the official documentation. We're Google Cloud SDK. each individual control plane component (API server, scheduler, etcd, You can define this declaratively Depending on how you wish to manage your application, this may or may not be to your liking, but you are free to tailor the configuration to disable any components you dont need. Create an AWS IAM policy for a Kublr account: For example: if all nodes This gives the application a ubiquitous . through its NoVolumeZoneConflict predicate, that pods which claim a given PersistentVolume For building this cluster you should require a working account on any of the two clouds. A multi-region architecture includes many different failure points. Once the second datacenter comes online, youll want to configure Cassandra keyspaces to replicate across both clusters. A multi-zonal cluster has a single replica of the control plane running in a single zone, and has nodes running in multiple zones. Provision a Multi-Region k3s cluster on Google Cloud with Terraform. Important: Remember to change your kubectl context back to the second GKE cluster. I believe it will help you to solve some interesting use cases. Azure Kubernetes Service (AKS) for multi-region deployment. Using tools such as the Cluster API you can define sets of machines to run as that represents that specific kubelet in the Kubernetes API. Select the preferred region (Recommended to keep in the same region as GKE) Also, It's possible to retrieve this command from the GCP console. We will write a terraform script to create infrastructure on Google cloud platform mainly Google Kubernetes Engine cluster in two different regions in a way that we can use both of them at the same time, and then we will deploy a sample application on both the clusters.I will share the github repository url at the end of the story. Heres what my file looked like, youll want to change the additional seeds and affinity labels to your configuration: Similar to the configuration for dc1, this configuration also uses affinity. However, orchestrating workloads across regions is still a considerable challenge . Now, for configuring the Kubernetes slave node, we can use the same Ansible collection and use the kube_salve ROLE from this collection for configuring the K8s slave node. Networking can be hard The basic requirement for any. You can then update the replication strategy to ensure data is replicated to the new datacenter. Today we will configure our Autopilot Kubernetes cluster on Google cloud platform with multi region support, and we will deploy a sample application with ingress to verify that traffic is getting served from both the clusters. In this instance, we will configure the Kubernetes master node. GKE running Kubernetes 1.20 or later with nodes such that a total of 12 CPU cores and 45 GB RAM can be allocated to YugabyteDB. a logical grouping called a region. Heres a picture that depicts what youve just deployed, focusing on the Cassandra nodes and networking: In the following posts in this series, well explore additional multi-datacenter topologies across multiple Kubernetes clusters, including Cassandra clusters in hybrid cloud and multi-cloud deployments. other, whenever that is feasible. To simulate such a failure, set the replica count of the YugabyteDB StatefulSets to 0 for the us-central1 region, as follows: Now rerun the queries from By default, the kube-dns deployment is accessed only by a ClusterIP and not a load balancer. This means you have to make sure that you have the latest kubectl version that is compatible across different Kubernetes distributions. Go to the GCP cloud and launch one Virtual Machine using a RedHat image. Note that I followed the instructions on this page up to the "Install K8ssandra" section and . Pods for better expected availability, reducing the risk that a correlated automatically adds zone labels to any PersistentVolumes that are linked to a specific an important concern, select at least three failure zones and replicate Update the Ansible inventory with the public IP of the AWS EC2 instance and the username of the EC2 instance. a consistent set of features: within a region, each zone offers the same Choose the "GKE Standard" option. To try this out, you'll need a Kubernetes cluster to test on. Youll want to specify a namespace corresponding to the region youre using. Click on "CREATE". Install Helm. Kubernetes' core does not create nodes for you; you need to do that yourself, www.faun.dev. kubernetes google-cloud-platform Share Follow edited May 4, 2018 at 19:22 Enable Cloud DNS API. You can support by buying me a coffee by clicking here or using the link below. Lets configure this slave node manually so that if you are not comfortable with Ansible, you will understand the flow. Go to your config-exercise directory. Typically you can obtain a command to do this by selecting the cluster in the GCP console and pressing the Connect button. In other words, the database cluster is fully protected against region failures but may temporarily experience higher latency, which is a better outcome than a complete outage of the business-critical database service. The default replica placement policy treats every YB-TServer as equal, irrespective of its placement_* flags. This includes the ESXi hypervisor, vCenter Server, NSX, HCX, and vSAN storage. Connect using YSQL and YCQL shells after reconnecting to the nodes in the us-west1 region to see that there is no impact to the availability of the cluster and the data stored therein. Understanding How YugabyteDB Runs on Kubernetes for details on how YugabyteDB self-heals the replicas when subjected to the failure of a fault domain (the cloud region, in this case) by auto-electing a new leader for each of the impacted shards in the remaining fault domains. In this section, each of these potential failure points is discussed. visit Scheduling and Eviction. Lets move to the Kubernetes master configuration. Now, this slave node is connected to the K8s master running on AWS. Install the kubectlcommand line tool by running the following command: Note that GKE is usually two or three major releases behind the upstream or OSS Kubernetes release. 1. cluster federation: not supported yet for Kubernetes Engine 2. multi-cluster ingress: in development, but may not something I am looking for 3. regional cluster: not applicable as it focuses on replication in only one region I am aware that my use case is not atypical. kubernetes.tf: for the configuration defining the characteristics of the Kubernetes cluster I'm working toward getting built. across multiple failure zones, typically where these zones fit within Lets now try to access http://<>/ping either by ping or browser, You should get similar output like this: If you refresh it multiple times, you might get response from different pods and regions. Note how the cluster was created with the following default values: Cluster type: zonal; Region: europe-west-1; Zone: B; Node count: 3 nodes, single-zone; Autoscaling: off Create Google Kubernetes Engine. Requests enter the Google's global network at one of the edge points of presence (POPs) close to the user, 1 1. Multi-Cluster Load Balancing with GKE One of the features I like the most about GCP is the external HTTP (S) Load Balancing. Stack Overflow. Lets create a directory k8s-multi-region-cluster. Our focus for this post will be on creating a Cassandra cluster running on Kubernetes clusters in multiple regions within a single cloud provider in this case Google Cloud. The kubeadm join command with private IP will only work inside the same VPC. As described in the Kubernetes documentation, a single Kubernetes cluster can run only inside a single zone of a single region. Deploying the App To deploy your infrastructure, follow the below steps. This page describes running Kubernetes across multiple zones. Create a multi-region CockroachDB Dedicated cluster Sign up for a CockroachDB Cloud account. For more details, please reference the first blog post in the series. Join us for Kubernetes Forums Seoul, Sydney, Bengaluru and Delhi - learn more at kubecon.ioDon't miss KubeCon + CloudNativeCon 2020 events in Amsterdam March. Its a Google-hosted service that supports deploying shared load balancing resources across clusters and across regions.We will use this feature to distribute traffic between both the clusters. If you have not installed the Helm client (helm), see Enter these commands to add cluster details to your configuration file: kubectl config --kubeconfig=config-demo set-cluster development --server=https://1.2.3.4 --certificate-authority=fake-ca-file kubectl config --kubeconfig=config-demo set-cluster scratch --server=https://5.6.7.8 --insecure-skip-tls-verify zone information. But for joining the Kubernetes slave nodes from all over the internet and from multiples cloud providers, we are required to use a public IP of the Kubernetes Master node instance. You must have three GKE clusters with Helm configured. This will make it possible to use the same network. reduce the impact of failures. We will only make few modifications here. Access Scope: All access to required Cloud APIs. Each private cloud has its own vCenter Server in a separate . Cloud Run can be used for the high-speed deployment of applications in a serverless environment. The scheduler then ensures, Good understanding of public cloud platforms, Primarily AWS / Azure / GCP. workload resources (such as Deployment Im will also be showing you a manual way to configure the Kubernetes slave node. . Later, we'll show how to stitch all this together in the deployment phase. Now that we have all the prerequisites ready, we can start working on our solution. Sing in your account and create two Kubernetes clusters in different regions. If your cluster spans multiple zones or regions, you can use node labels in conjunction with Cloud serverless CI/CD platform App modernization Multi-cloud Automate policy and security at scale for your hybrid and multi-cloud Kubernetes deployments. This means workloads will be distributed across multiple nodes of a single Kubernetes cluster running in a single region. Open an issue in the GitHub repo if you want to Enable VPC native: In the same VPC as Cloud SQL, Cloud Memorystore, Cloud Filestore, and Memorystore are present. However, there is higher latency for some of the transactions, since the farthest us-east1 region has to be involved in the write path. AWS Deep Learning Containers Are Awesome , Why Should I Consider using Serverless Computing, Improve Your Python Code With These Useful Features, https://ankush-chavan.medium.com/launching-a-website-in-a-docker-using-ansible-e41bcdb889f6, https://ankush-chavan.medium.com/publish-multiple-roles-using-ansible-galaxy-collections-27c29a0e7a28, https://download.docker.com/linux/centos/7/x86_64/stable/, https://packages.cloud.google.com/yum/repos/kubernetes-el7-$basearch. Sample Application Deployment Kubernetes YAML Files Deployment. failure affects your whole workload. Execute the following command to download the yb-multiregion-k8s-setup.py script to automate the setup of the load balancers: The script starts out by creating a new namespace in each of the three clusters. The Google Kubernetes Engine (GKE) is a fully managed Kubernetes service for deploying, managing, and scaling containerized applications on Google Cloud. The first is one youve already taken care of: using the same Google Cloud network for both GKE clusters means the nodes in the new datacenter will be able to communicate with nodes in the original datacenter. The eks-multi-region-deploy.sh script will build the Color App container image locally, tag the image, and push it to Amazon ECR. You need to allow this load balancer to be In this way, we have built a true Multi-Cloud Kubernetes Cluster to achieve high availability. These labels can include Direct internet access: The local machine should have direct internet access to be able to connect to AWS API and Kubernetes API of the clusters provisioned in your AWS account. We will write and run our terraform scripts here. By itself, Kubernetes does not include zone-aware networking. as a set of failure zones (also called availability zones) that provide Step 1: Ensure cloud readiness We need to enable a couple of GCP service APIs to use this feature. Important: Youll likely need to first change your kubectl context back to the first GKE cluster, for example using the kubectl config use-context command. type=LoadBalancer, the load balancer might only send traffic to Pods running in the Kubernetes multi-cluster is an environment with multiple Kubernetes clusters. First, youre going to need a Kubernetes cluster in which you can create the first Cassandra datacenter. Use paired regions. zone. are unhealthy, you might need to run a repair Job with a special These hints enable the Ensure helm is installed by using the Helm version command: Expect an output similar to the following output: Note that the tiller server side component has been removed in Helm 3. Let's iterate on that solution, and start by creating some Terraform modules , one for the Kubernetes service, and one for the Kubernetes cluster; These modules will allow us to create multiple consistent clusters in different regions by simply passing in variables. We are going to deploy an Active-Active Architecture Multi-Region Kubernetes Cluster with Terraform in this story.This will make our cluster highly available since we have two different clusters to serve the traffic and fault tolerant since we are deploying both clusters in different regions. You can change this as per your need. (Python 3 is a prerequisite for this). Kubernetes clusters are growing in number and size inside organizations. Show some appreciation through applauds if you like this article. Youll execute something like the following for each of these keyspaces: Important: Remember to create or alter the replication strategy for any keyspaces you need for your application so that you have the desired number of replicas in each datacenter. Open the yb-multiregion-k8s-setup.py script and edit the contexts and regions sections to reflect your own configuration, as follows: Run the script using the following command: We now have three GKE clusters that essentially have a global DNS service as long as services use zone-scoped namespaces to access each other. Youll want to change these values for your own environment. report a problem You start by adding the Helm charts repository, then creating override files, and then proceeding to download YugabyteDB. worker nodes for your cluster across multiple failure domains, and rules to On the Google Cloud Console, go to the "Kubernetes Engine (Clusters)" page. You need to ensure that the storage classes used by the pods in a given zone are always pinned to that zone only. Go to the K8s master node and check if this note is connected successfully and is ready. Kubernetes is designed so that a single Kubernetes cluster can run But if you are not comfortable with Ansible, its very much okay. Connecting to the Kubernetes cluster Use the gcloud command-line tool to connect to the Kubernetes cluster: gcloud container clusters get-credentials <cluster_name> --zone <zone> --project <project_id> Note: replace the variables with the values used in the inventory file. storage in that class may use. When building this example for myself, I provided values for the environment variables used by the Terraform script to match my desired environment. Let us configure another slave node on the GCP cloud. Experience on automation tools like Ansible, Terraform, Helm, etc. We can now apply these yaml configuration using kubectl command. ; Enable Kubernetes Engine API. Actually you may create as many as you need though, but here we create a Host Cluster and Member Cluster 1 only. For any help or suggestions connect with me on Twitter at @TheNameIsAnkush or find me on LinkedIn. Because it is a single binary, it is quite easy to download and install, all while giving you the same bells and whistles . For building this cluster you should require a working account on any of the two clouds. How Kubernetes Cluster Works; Kubernetes-dashboard; Run sample nginx service; Use port-forward to access the nginx service on browser; Creating a VPC. Plan for multiregion deployment Best practice When you deploy multiple AKS clusters, choose regions where AKS is available. Output: To add the YugabyteDB charts repository, run the following command: Make sure that you have the latest updates to the repository by running the following command: Validate that you have the updated chart version, as follows: Add the following contents to a file named overrides-us-west1-b.yaml: Add the following contents to a file named overrides-us-central1-b.yaml: Add the following contents to a file named overrides-us-east1-b.yaml: Create the YugabyteDB cluster such that one third of the nodes are hosted in each Kubernetes cluster, as follows: There is a number of commands that you can execute to check the status of the cluster. Here, run the following command to check if the Kubernetes slave node from Azure cloud is connected to the Kubernetes master and is ready to use. To create this first cluster, follow the instructions for K8ssandra on Google Kubernetes Engine (GKE), which reference scripts provided as part of the K8ssandra GCP Terraform Example. When you set up your cluster, you might also need to consider whether and how Now we will create a new VPC in our GCP project using below command. After the load balancers are created, it configures them using Kubernetes ConfigMap in such a way that they forward DNS requests for zone-scoped namespaces to the relevant Kubernetes cluster's DNS server. etcd is a consistent and highly-available key value store used as Kubernetes' backing store for all cluster data. See Now that we have our networking solution ready, we will create our primary Kubernetes cluster. Objective 1: Multi-cluster ingress/ Global LoadBalancing.
