Alauda Service Mesh

Installation

This article will use two AWS EKS (Amazon Elastic Kubernetes Service) clusters, c1 and c2, located in different VPCs (Virtual Private Clouds) as examples to illustrate how to build a multi-cluster, multi-network service mesh.

NOTE

For demonstration purposes, this article only selects two clusters to build the mesh. In practice, you can add more clusters that meet the prerequisites to the service mesh according to your needs.

TOC

Prerequisites

  • For private clouds, ensure that Kubernetes LoadBalancer (e.g., MetaLB) is configured on all clusters to provide load balancing capabilities for Istio gateways deployed on the clusters.
  • All clusters have been connected to the platform.
  • Monitoring components have been deployed for all clusters through , including VictoriaMetrics.
    To ensure that monitoring data from multiple clusters can be aggregated, make sure that the monitoring data of multiple clusters to be added to the mesh can be collected to the same VictoriaMetrics Center with the same data query address. Note: Tested, VictoriaMetrics supports the multi-master architecture service mesh well. For support with other monitoring solutions, please contact technical support.
  • All control nodes and load balancing devices (if any) in all clusters must have port 6443 for kube-apiserver open, and the 6443 port of the load balancing device must forward traffic to the 6443 port of the control node.
  • Ensure that the Kubernetes version of the clusters is compatible with the Istio version supported by the platform. For detailed information, see Istio's Supported Kubernetes Versions.

Create a service mesh

Select one of the prepared clusters and create a service mesh.

When creating the mesh, configure the corresponding parameters as follows, and configure other parameters as needed:

  • Deploy Istio for the mesh.
  • Choose Multi-cluster for the Mesh Architecture.
  • Choose Multi-network for the Network Type. Note: The platform will automatically deploy east-west traffic gateways for all clusters joining the mesh, connecting the networks between clusters.
  • Integrate with the monitoring components provided by the platform for the Monitoring System.

Add clusters

  1. In the left navigation bar, click Service Mesh > Mesh.

  2. Click the Service Mesh Name of the cluster to be added.

  3. Under the Mesh Details tab, in the Mesh Deployment section, click Add Cluster.

  4. In the Basic Information section, select the cluster to join the service mesh.

  5. Configure the mesh configuration and components at the cluster level according to the actual deployment needs.

  6. Click Add.

    Note:

    • After successful addition, the system will deploy service mesh-related components on the cluster in sequence. Click in the Mesh Deployment section to view the deployment progress.

    • After adding a cluster, the global configuration of the mesh (monitoring system, Elasticsearch integration configuration) will automatically synchronize to the newly added cluster.
