$ export CTX_EXTERNAL_CLUSTER=Ĭluster configuration Mesh operator stepsĪ mesh operator is responsible for installing and managing the external Istio control plane on the external cluster. Set the CTX_EXTERNAL_CLUSTER, CTX_REMOTE_CLUSTER, and REMOTE_CLUSTER_NAME now. The name of the secret that holds the TLS certs for the ingress gateway on the external control plane cluster. This is used by the remote cluster to access the external control plane. The hostname for the ingress gateway on the external control plane cluster. The context name in the default Kubernetes configuration file used for accessing the remote cluster. The context name in the default Kubernetes configuration file used for accessing the external control plane cluster. The following environment variables will be used throughout to simplify the instructions: Variable Multicluster configuration could also be used to enable access Need to modify the installation procedure to enable access. If the API server is not directly accessible, you will Many cloud providers make API servers publicly accessible The Kubernetes API server in the remote cluster must be accessible to the externalĬontrol plane cluster. Its Kubernetes API server also provides the mesh configuration used by the external control plane (istiod) The second cluster is a remote cluster that will run the mesh application workloads. An ingress gateway is also installed in the istio-system namespace to provideĬross-cluster access to the external control plane. The first cluster will host the external control plane installed in theĮxternal-istiod namespace. This guide requires that you have two Kubernetes clusters with any of the The Kubernetes API server, as shown in the above diagram. The external control plane will remotely access this configuration from In addition to the mesh services themselves. The mesh administrator will use the config cluster to configure the mesh resources (gateways, virtual services, etc.) The first remote cluster connected to an external control plane serves as the config cluster for the mesh itself. While configuration and management of the external control plane is done by the mesh operator in the external cluster, Which exposes the endpoints needed for discovery, CA, injection, and validation. Mesh operators install and manage Istio control planes while meshĮxternal control plane cluster and remote clusterĮnvoy proxies (sidecars and gateways) running in the remote cluster access the external istiod via an ingress gateway This deployment model allows a clear separationīetween mesh operators and mesh administrators.

Plane cluster (or multiple clusters) comprising the mesh. The external control plane deployment modelĪllows a mesh operator to install and manage a control plane on an external cluster, separate from the data This guide walks you through the process of installing an external control planeĪnd then connecting one or more remote clusters to it. Set up the control plane in the external cluster.
