Gloo Mesh Core deploys alongside your Istio installations in single or multicluster environments, and gives you instant insights into your Istio environment through a custom dashboard.

You can follow this guide to customize settings for an advanced Gloo Mesh Core installation. To learn more about the benefits and architecture, see About.

Before you begin

  1. Install the following command-line (CLI) tools.

    • kubectl, the Kubernetes command line tool. Download the kubectl version that is within one minor version of the Kubernetes clusters you plan to use.
    • meshctl, the Solo command line tool.
        curl -sL https://run.solo.io/meshctl/install | GLOO_MESH_VERSION=v2.5.11 sh -
export PATH=$HOME/.gloo-mesh/bin:$PATH
    • helm, the Kubernetes package manager.

  2. Set your Gloo Mesh Core license key as an environment variable. If you do not have one, contact an account representative. If you prefer to specify license keys in a secret instead, see Licensing. To check your license’s validity, you can run meshctl license check --key $(echo ${GLOO_MESH_CORE_LICENSE_KEY} | base64 -w0).

      export GLOO_MESH_CORE_LICENSE_KEY=<license_key>

  3. Set the Gloo Mesh Core version. This example uses the latest version. You can find other versions in the Changelog documentation. Append -fips for a FIPS-compliant image, such as 2.5.11-fips. Do not include v before the version number.

      export GLOO_VERSION=2.5.11

  4. Create or use an existing Kubernetes cluster for a single-cluster setup, or for a multicluster setup, at least two existing Kubernetes clusters. The instructions in this guide assume one management cluster and two workload clusters.

    • The cluster name must be alphanumeric with no special characters except a hyphen (-), lowercase, and begin with a letter (not a number).
  5. Production installations: Review Best practices for production to prepare your optional security measures. For example, before you begin your Gloo installation, you can provide your own certificates to secure the management server and agent connection, and set up secure access to the Gloo UI.

Single cluster

Install all Gloo Mesh Core components in the same cluster as your Istio service mesh.

  1. Save the name of your cluster as an environment variable.

      export CLUSTER_NAME=<cluster_name>

  2. Add and update the Helm repository for Gloo.

      helm repo add gloo-platform https://storage.googleapis.com/gloo-platform/helm-charts
helm repo update

  3. Install the Gloo CRDs.

      helm upgrade -i gloo-platform-crds gloo-platform/gloo-platform-crds \
   --namespace=gloo-mesh \
   --create-namespace \
   --version=$GLOO_VERSION \
   --set installEnterpriseCrds=false

  4. Prepare a Helm values file to provide your customizations. To get started, you can use the minimum settings in the following profile as a basis. These settings enable all components that are required for a single-cluster Gloo Mesh Core installation.

      curl https://storage.googleapis.com/gloo-platform/helm-profiles/$GLOO_VERSION/gloo-core-single-cluster.yaml > gloo-single.yaml
open gloo-single.yaml

  5. Decide how you want to secure the relay connection between the Gloo management server and agent. In test and POC environments, you can use Gloo self-signed certificates to secure the connection. If you plan to use Gloo Mesh Core in production, it is recommended to bring your own certificates instead. For more information, see Setup options.

    Use your preferred PKI provider to generate your root CA and intermediate CA credentials. You then store the intermediate CA credentials in your cluster so that you can leverage Gloo Mesh Core’s built-in capability to automatically issue and sign the client TLS certificate for the Gloo agent. For more information, see the Bring your own CAs with automatic client TLS certificate rotation.

    1. Create your root CA, intermediate CA credentials, server TLS certificate, and relay identity token, and store them as the following Kubernetes secrets in the gloo-mesh namespace:

      • relay-root-tls-secret that holds the root CA key, TLS certificate, and certificate chain
      • relay-tls-signing-secret that holds the intermediate CA key, TLS certificate, and certificate chain
      • relay-server-tls-secret that holds the server key, TLS certificate, and certificate chain for the Gloo management server
      • telemetry-root-secret that holds the certificate chain information for the telemetry collector agent
      • relay-identity-token-secret that holds the relay identity token value

      You can use your preferred PKI provider to create the TLS certificates or follow the steps in BYO server certificate with managed client certificate to create the relay identity token and the TLS certificate by using OpenSSL.

    2. In your Helm values file, add the following values.

        glooMgmtServer: 
  enabled: true
  registerCluster: true
  serviceType: ClusterIP
  relay:
    disableCaCertGeneration: true
    signingTlsSecret:

      name: cilium-run
      Helm valueDescription
      glooMgmtServer.relay.disableCaCertGenerationDisable the generation of self-signed certificates to secure the relay connection between the Gloo management server and agent.
      glooMgmtServer.relay.signingTlsSecretAdd the name and namespace of the Kubernetes secret that holds the intermediate CA credentials that you created earlier.
      glooMgmtServer.relay.tlsSecretAdd the name and namespace of the Kubernetes secret that holds the server TLS certificate for the Gloo management server that you created earlier.
      glooMgmtServer.relay.tokenSecretAdd the name, namespace, and key of the Kubernetes secret that holds the relay identity token that you created earlier.
      glooAgent.relay.rootTlsSecretAdd the name and namespace of the Kubernetes secret that holds the root CA credentials that you created earlier.
      glooAgent.relay.tokenSecretAdd the name, namespace, and key of the Kubernetes secret that holds the relay identity token that you created earlier.
      telemetryCollector.extraVolumesAdd the telemetry-root-secret Kubernetes secret that you created earlier to the root-ca volume. Make sure that you also add the other volumes to your telemetry collector configuration.

    Use your preferred PKI provider to create the root CA, server TLS, and client TLS certificates. Then, store these certificates in the cluster so that the Gloo agent uses a client TLS certificate when establishing the first connection with the Gloo management server. No relay identity tokens are used. With this approach, you cannot use Gloo Mesh Core’s built-in client TLS certificate rotation capabilities. Instead, you must set up your own processes to monitor the expiration of your certificates and to rotate them before they expire. For more information, see Bring your own CAs and client TLS certificates.

    1. Create your root CA, server, and client TLS certificates, and store them as the following Kubernetes secrets in the gloo-mesh namespace:

      • relay-server-tls-secret that holds the server TLS certificate for the Gloo management server
      • relay-client-tls-cert that holds the client TLS certificate for the Gloo agent
      • telemetry-root-secret that holds the certificate chain information for the telemetry collector agent

      You can use your preferred PKI provider to create the TLS certificates or follow the steps in Create TLS certificates with OpenSSL to create them by using OpenSSL.

    2. In your Helm values file for the management server, add the following values.

        
glooMgmtServer:
  enabled: true
  registerCluster: true
  relay:
    disableCa: true
    disableCaCertGeneration: true
    disableTokenGeneration: true

      Helm valueDescription
      glooMgmtServer.relay.disableCaDisable the generation of self-signed root and intermediate CA certificates and the use of identity tokens to establish initial trust between the Gloo management server and agent.
      glooMgmtServer.relay.disableCaCertGenerationDisable the generation of self-signed certificates to secure the relay connection between the Gloo management server and agent.
      glooMgmtServer.relay.disableTokenGenerationDisable the generation of relay identity tokens.
      glooMgmtServer.relay.tlsSecretAdd the name and namespace of the Kubernetes secret that holds the server TLS certificate for the Gloo management server that you created earlier.
      glooMgmtServer.relay.tokenSecretSet all values to null to instruct the Gloo management server to not use identity tokens to establish initial trust with Gloo agents.
      glooAgent.relay.clientTlsSecretAdd the name and namespace of the Kubernetes secret that holds the client TLS certificate for the Gloo agent that you created earlier.
      glooAgent.tokenSecretSet all values to null to instruct the Gloo agent to not use identity tokens to establish initial trust with the Gloo management server.
      telemetryCollector.extraVolumesAdd the telemetry-root-secret Kubernetes secret that you created earlier to the root-ca volume. Make sure that you also add the other volumes to your telemetry collector configuration.

    You can use Gloo to generate self-signed certificates and keys for the root and intermediate CA. These credentials are used to derive the server TLS certificate for the Gloo management server and client TLS certificate for the Gloo agent. For more information, see Self-signed CAs with automatic client certificate rotation.

    In your Helm values file, add the following values. Note that mTLS is the default mode in Gloo Mesh Core and does not require any additional configuration.

      
glooMgmtServer:
  enabled: true
glooAgent: 
  enabled: true

    Use your preferred PKI provider to create the server TLS certificate for the Gloo management server. For more information, see Bring your own server TLS certificate.

    1. Create your root CA credentials and derive the server TLS certificate and certificate chain information. To create the TLS certificate, you can use your preferred PKI provider or follow the steps in BYO server certificates to create a custom server TLS certificate by using OpenSSL. Store this information in the following secrets in the gloo-mesh namespace.
      • relay-server-tls-secret-custom: The key and TLS certificate for the Gloo management server, and root CA certificate information for the certificate chain. Note that you can use a different name, but you cannot use relay-server-tls-secret as this name is reserved by the Gloo management server when creating self-signed root CAs and server TLS certificates.
      • telemetry-root-secret: The root CA certificate for the certificate chain.
    2. In your Helm values file, add the following values.
        
glooMgmtServer:
  serviceType: ClusterIP
  registerCluster: true
  enabled: true
  relay: 
    tlsSecret:
      name: relay-server-tls-secret-custom

      name: cilium-run
      Helm valueDescription
      glooMgmtServer.relay.tlsSecret.nameThe name and namespace of the Kubernetes secret where you stored your custom server TLS certificate.
      glooMgmtServer.extraEnvs.RELAY_TOKENSpecify the relay token that the Gloo management server and agent use to establish initial trust. When you install Gloo Mesh Core and set RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATION to true, the connection between the Gloo management server and agent is automatically secured by using simple, server-side TLS. In a simple TLS setup, only the management server presents a certificate to authenticate its identity. The identity of the agent is not verified. To ensure that only trusted agents connect to the management server, the relay identity token is used. The relay identity token can be any string value and is stored in the relay-identity-token-secret Kubernetes secret on the management cluster. You must set the same value in glooAgent.extraEnvs.RELAY_TOKEN.value to allow the Gloo agent to connect to the Gloo management server.
      glooMgmtServer.extraEnvs.
      RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATION      		Set this value to true to not require a client TLS certificate from the Gloo agent to prove the agent’s identity and establish the connection with the management server.
      glooAgent.extraEnvs.
      RELAY_DISABLE_SERVER_CERTIFICATE_VALIDATION      		Set to true to skip validating the server TLS certificate that the Gloo management server presents. This setting is required to configure the relay connection for TLS.
      telemetryCollector.extraVolumesAdd the telemetry-root-secret Kubernetes secret that you created earlier to the root-ca volume. Make sure that you also add the other volumes to your telemetry collector configuration.

    Use Gloo Mesh Core to create a self-signed server TLS certificate that the Gloo management server presents when the Gloo agent connects. For more information, see Self-signed server TLS certificate.

    In your Helm values file, add the following values.

      
glooMgmtServer:
  serviceType: ClusterIP
  registerCluster: true
  enabled: true
  extraEnvs: 
    RELAY_TOKEN: 
      value: "My token"

    RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATION    		Set this value to true to not require a client TLS certificate from the Gloo agent to prove the agent’s identity and establish the connection with the management server. This setting is required when you want to use simple TLS to secure the connection between the Gloo management server and agent.
    glooAgent.extraEnvs.RELAY_TOKENUse the same value that you set in glooMgmtServer.extraEnvs.RELAY_TOKEN.
    glooAgent.extraEnvs.
    RELAY_DISABLE_SERVER_CERTIFICATE_VALIDATION    		Set to true to skip validating the server TLS certificate that the Gloo management server presents. This setting is required to configure the relay connection for TLS.

  6. Edit the file to provide your own details for settings that are recommended for production deployments, such as the following settings.

    FieldDecription
    glooAgent.resources.limitsAdd resource limits for the gloo-mesh-agent pod, such as cpu: 500m and memory: 512Mi.
    glooMgmtServer.resources.limitsAdd resource limits for the gloo-mesh-mgmt-server pod, such as cpu: 1000m and memory: 1Gi.
    glooMgmtServer.safeMode
    glooMgmtServer.safeStartWindow    		Configure how you want the Gloo management server to handle translation after a Redis restart. For available options, see Redis safe mode options.
    glooMgmtServer.serviceOverrides.metadata.annotationsAdd annotations for the management server load balancer as needed, such as AWS-specific load balancer annotations. For more information, see Deployment and service overrides.
    glooUi.authSet up OIDC authorization for the Gloo UI. For more information, see UI authentication.
    prometheus.enabledDisable the default Prometheus instance as needed to provide your own. Otherwise, you can keep the default Prometheus server enabled, and deploy a production-level server to scrape metrics from the server. For more information on each option, see Best practices for collecting metrics in production.
    redisDisable the default Redis deployment and provide your own backing database as needed. For more information, see Backing databases.

  7. Use the customizations in your Helm values file to install the Gloo Mesh Core components in your cluster.

      helm upgrade -i gloo-platform gloo-platform/gloo-platform \
    -n gloo-mesh \
    --version $GLOO_VERSION \
    --values gloo-single.yaml \
    --set common.cluster=$CLUSTER_NAME \
    --set licensing.glooMeshCoreLicenseKey=$GLOO_MESH_CORE_LICENSE_KEY

  8. Verify that your Gloo Mesh Core setup is correctly installed. If not, try debugging the relay connection. Note that this check might take a few seconds to verify that:

    • Your Gloo product license is valid and current.
    • The Gloo CRDs are installed at the correct version.
    • The management plane pods in the management cluster are running and healthy.
    • The Gloo agent is running and connected to the management server.
      meshctl check

  9. If you have not installed Istio yet, see the guides for installing Istio in sidecar or ambient mode.

Multicluster

In a multicluster setup, you deploy the Gloo management plane into a dedicated management cluster, and the Gloo data plane into one or more workload clusters that run Istio service meshes.

Management plane

Deploy the Gloo management plane into a dedicated management cluster.

  1. Save the name and kubeconfig context for your management cluster in environment variables.

      export MGMT_CLUSTER=<management-cluster-name>
export MGMT_CONTEXT=<management-cluster-context>

  2. Add and update the Helm repository for Gloo.

      helm repo add gloo-platform https://storage.googleapis.com/gloo-platform/helm-charts
helm repo update

  3. Install the Gloo CRDs.

      helm upgrade -i gloo-platform-crds gloo-platform/gloo-platform-crds \
   --namespace=gloo-mesh \
   --create-namespace \
   --version=$GLOO_VERSION \
   --set installEnterpriseCrds=false \
   --kube-context $MGMT_CONTEXT
  4. Prepare a Helm values file to provide your customizations. To get started, you can use the minimum settings in the following profile as a basis. These settings enable all components that are required for a Gloo management plane installation.
      curl https://storage.googleapis.com/gloo-platform/helm-profiles/$GLOO_VERSION/gloo-core-mgmt.yaml > mgmt-plane.yaml
open mgmt-plane.yaml

  5. Decide how you want to secure the relay connection between the Gloo management server and agents. In test and POC environments, you can use self-signed certificates to secure the connection. If you plan to use Gloo Mesh Core in production, it is recommended to bring your own certificates instead. For more information, see Setup options.

    Use your preferred PKI provider to generate your root CA and intermediate CA credentials. You then store the intermediate CA credentials in your cluster so that you can leverage Gloo Mesh Core’s built-in capability to automatically issue and sign client TLS certificates for Gloo agents. For more information, see the Bring your own CAs with automatic client TLS certificate rotation.

    1. Create your root CA, intermediate CA, server, and telemetry gateway credentials, as well as relay identity token, and store them as the following Kubernetes secrets in the gloo-mesh namespace on the management cluster:

      • relay-root-tls-secret that holds the root CA certificate
      • relay-tls-signing-secret that holds the intermediate CA credentials
      • relay-server-tls-secret that holds the server key, TLS certificate and certificate chain information for the Gloo management server
      • relay-identity-token-secret that holds the relay identity token value
      • telemetry-root-secret that holds the root CA certificate for the certificate chain
      • gloo-telemetry-gateway-tls-secret that holds the key, TLS certificate and certificate chain for the Gloo telemetry gateway

      You can use your preferred PKI provider to create the TLS certificates or follow the steps in BYO server certificate with managed client certificate to create these TLS credentials with OpenSSl.

    2. In your Helm values file for the management server, add the following values.

    Use your preferred PKI provider to create the root CA, server TLS, client TLS, and telemetry gateway certificates. Then, store these certificates in the cluster so that the Gloo agent uses a client TLS certificate when establishing the first connection with the Gloo management server. No relay identity tokens are used. With this approach, you cannot use Gloo Mesh Core’s built-in client TLS certificate rotation capabilities. Instead, you must set up your own processes to monitor the expiration of your certificates and to rotate them before they expire. For more information, see Bring your own CAs and client TLS certificates.

    1. Create your root CA, server, client, and telemetry gateway TLS certificates. You can use your preferred PKI provider to do that or follow the steps in Create certificates with OpenSSL to create custom TLS certificates by using OpenSSL. Then, you store the following information in a Kubernetes secret in the gloo-mesh namespace on the management cluster.
      • relay-server-tls-secret that holds the server key, TLS certificate and certificate chain information for the Gloo management server

      relay.disableCaDisable the generation of self-signed root and intermediate CA certificates and the use of identity tokens to establish initial trust between the Gloo management server and agent.
      relay.disableCaCertGenerationDisable the generation of self-signed certificates to secure the relay connection between the Gloo management server and agent.
      relay.disableTokenGenerationDisable the generation of relay identity tokens.
      relay.tlsSecretAdd the name and namespace of the Kubernetes secret that holds the server TLS certificate for the Gloo management server that you created earlier.
      relay.tokenSecretSet all values to null to instruct the Gloo management server to not use identity tokens to establish initial trust with Gloo agents.
      telemetryGateway.extraVolumesAdd the gloo-telemetry-gateway-tls-secret Kubernetes secret that you created earlier to the tls-keys volume. Make sure that you also add the other volumes to your telemetry gateway configuration.
      telemetryCollector.extraVolumesAdd the telemetry-root-secret Kubernetes secret that you created earlier to the root-ca volume. Make sure that you also add the other volumes to your telemetry collector configuration.

    You can use Gloo to generate self-signed certificates and keys for the root and intermediate CA. These credentials are used to derive the server TLS certificate for the Gloo management server and client TLS certificate for the Gloo agent. Note that this setup is not recommended for production, but can be used for testing purposes. For more information, see Self-signed CAs with automatic client certificate rotation.

    In your Helm values file for the management server, add the following values. Note that mTLS is the default mode in Gloo Mesh Core and does not require any additional configuration on the management server.

      
glooMgmtServer:
  enabled: true

    Use your preferred PKI provider to create the server TLS certificate for the Gloo management server. For more information, see Bring your own server TLS certificate.

    1. Create your root CA credentials and derive a server TLS certificate. To create the TLS certificate, you can use your preferred PKI provider or follow the steps in BYO server certificate to create a custom server TLS certificate by using OpenSSL. Make sure that you have the following Kubernetes secrets in the management cluster:

      • relay-server-tls-secret-custom: The key and TLS certificate for the Gloo management server, and root CA certificate information for the certificate chain. Note that you can use a different name, but you cannot use relay-server-tls-secret as this name is reserved by the Gloo management server when creating self-signed root CAs and server TLS certificates.
      • gloo-telemetry-gateway-tls-secret-custom: The key and TLS certificate for the Gloo telemetry gateway, and root CA certificate information for the certificate chain. It is recommended to use the same credentials that you use for the Gloo management server. Note that you can use a different name, but you cannot use gloo-telemetry-gateway-tls-secret as this name is reserved by the Gloo management server when creating self-signed certificates.
      • telemetry-root-secret: The root CA certificate for the certificate chain.

    2. In your Helm values file for the management server, add the following values.

  disableCertGeneration: true
      Helm valueDescription
      relay.tlsSecret.nameAdd the name of the Kubernetes secret with the custom server TLS secret that you created earlier.
      RELAY_TOKENSpecify the relay token that the Gloo management server and agent use to establish initial trust. When you install Gloo Mesh Core and set RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATION to true, the connection between the Gloo management server and agent is automatically secured by using simple, server-side TLS. In a simple TLS setup, only the management server presents a certificate to authenticate its identity. The identity of the agent is not verified. To ensure that only trusted agents connect to the management server, the relay identity token is used. The relay identity token can be any string value and is stored in the relay-identity-token-secret Kubernetes secret on the management cluster. You must set the same value in glooAgent.extraEnvs.RELAY_TOKEN.value when you install the Gloo agent to allow the Gloo agent to connect to the Gloo management server.
      RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATIONSet this value to true to not require a client TLS certificate from the Gloo agent to prove the agent’s identity and establish the connection with the management server. This setting is required when you want to use simple TLS to secure the connection between the Gloo management server and agent.
      telemetryGateway.extraVolumesAdd the gloo-telemetry-gateway-tls-secret-custom Kubernetes secret that you created earlier to the tls-keys volume. Make sure that you also add the other volumes to your telemetry gateway configuration.
      telemetryCollector.extraVolumesAdd the telemetry-root-secret Kubernetes secret that you created earlier to the root-ca volume. Make sure that you also add the other volumes to your telemetry collector configuration.

    Use Gloo Mesh Core to create a self-signed server TLS certificate that the Gloo management server presents when workload cluster agents connect. This setup is not recommended for production, but can be used for testing purposes. For more information, see Self-signed server TLS certificate.

    In your Helm values file for the management server, add the following values.

      
glooMgmtServer:
  enabled: true
  extraEnvs:
    RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATION:
      value: "true"  
    RELAY_TOKEN: 
      value: "My token"

    RELAY_DISABLE_CLIENT_CERTIFICATE_AUTHENTICATIONSet this value to true to not require a client TLS certificate from the Gloo agent to prove the agent’s identity and establish the connection with the management server. This setting is required when you want to use simple TLS to secure the connection between the Gloo management server and agent.

  6. Edit the file to provide your own details for settings that are recommended for production deployments, such as the following settings.

    FieldDecription
    glooMgmtServer.resources.limitsAdd resource limits for the gloo-mesh-mgmt-server pod, such as cpu: 1000m and memory: 1Gi.
    glooMgmtServer.safeMode
    glooMgmtServer.safeStartWindow    		Configure how you want the Gloo management server to handle translation after a Redis restart. For available options, see Redis safe mode options.
    glooMgmtServer.serviceOverrides.metadata.annotationsAdd annotations for the management server load balancer as needed, such as AWS-specific load balancer annotations. For more information, see Deployment and service overrides.
    glooUi.authSet up OIDC authorization for the Gloo UI. For more information, see UI authentication.
    prometheus.enabledDisable the default Prometheus instance as needed to provide your own. Otherwise, you can keep the default Prometheus server enabled, and deploy a production-level server to scrape metrics from the server. For more information on each option, see Best practices for collecting metrics in production.
    redisDisable the default Redis deployment and provide your own backing database as needed. For more information, see Backing databases.

  7. Use the customizations in your Helm values file to install the Gloo management plane components in your management cluster.

      helm upgrade -i gloo-platform gloo-platform/gloo-platform \
   --kube-context $MGMT_CONTEXT \
   -n gloo-mesh \
   --version $GLOO_VERSION \
   --values mgmt-plane.yaml \
   --set common.cluster=$MGMT_CLUSTER \
   --set licensing.glooMeshCoreLicenseKey=$GLOO_MESH_CORE_LICENSE_KEY

  8. Verify that the management plane pods have a status of Running.

      kubectl get pods -n gloo-mesh --context $MGMT_CONTEXT

    Example output:

      NAME                                      READY   STATUS    RESTARTS   AGE

prometheus-server-57cd8c74d4-2bc7f        2/2     Running   0          30s

  9. Save the external address and port that your cloud provider assigned to the gloo-mesh-mgmt-server service. The gloo-mesh-agent agent in each workload cluster accesses this address via a secure connection.

      export MGMT_SERVER_NETWORKING_DOMAIN=$(kubectl get svc -n gloo-mesh gloo-mesh-mgmt-server --context $MGMT_CONTEXT -o jsonpath="{.status.loadBalancer.ingress[0]['hostname','ip']}")
export MGMT_SERVER_NETWORKING_PORT=$(kubectl get svc -n gloo-mesh gloo-mesh-mgmt-server --context $MGMT_CONTEXT -o jsonpath='{.spec.ports[?(@.name=="grpc")].port}')
export MGMT_SERVER_NETWORKING_ADDRESS=${MGMT_SERVER_NETWORKING_DOMAIN}:${MGMT_SERVER_NETWORKING_PORT}
echo $MGMT_SERVER_NETWORKING_ADDRESS

  10. Save the external address and port that your cloud provider assigned to the Gloo OpenTelemetry (OTel) gateway service. The OTel collector agents in each workload cluster send metrics to this address.

      export TELEMETRY_GATEWAY_IP=$(kubectl get svc -n gloo-mesh gloo-telemetry-gateway --context $MGMT_CONTEXT -o jsonpath="{.status.loadBalancer.ingress[0]['hostname','ip']}")
export TELEMETRY_GATEWAY_PORT=$(kubectl get svc -n gloo-mesh gloo-telemetry-gateway --context $MGMT_CONTEXT -o jsonpath='{.spec.ports[?(@.name=="otlp")].port}')
export TELEMETRY_GATEWAY_ADDRESS=${TELEMETRY_GATEWAY_IP}:${TELEMETRY_GATEWAY_PORT}
echo $TELEMETRY_GATEWAY_ADDRESS

Data plane

Register each workload cluster with the Gloo management plane by deploying Gloo data plane components. A deployment named gloo-mesh-agent runs the Gloo agent in each workload cluster.

  1. For the workload cluster that you want to register with Gloo, set the following environment variables. You update these variables each time you follow these steps to register another workload cluster.

      export REMOTE_CLUSTER=<workload_cluster_name>
export REMOTE_CONTEXT=<workload_cluster_context>

  2. In the management cluster, create a KubernetesCluster resource to represent the workload cluster and store relevant data, such as the workload cluster’s local domain.

      kubectl apply --context $MGMT_CONTEXT -f- <<EOF
apiVersion: admin.gloo.solo.io/v2
kind: KubernetesCluster
metadata:
   name: ${REMOTE_CLUSTER}
   namespace: gloo-mesh
spec:
   clusterDomain: cluster.local
EOF

  3. In your workload cluster, apply the Gloo CRDs.

      helm upgrade -i gloo-platform-crds gloo-platform/gloo-platform-crds \
   --namespace=gloo-mesh \
   --create-namespace \
   --version=$GLOO_VERSION \
   --set installEnterpriseCrds=false \
   --kube-context $REMOTE_CONTEXT
  4. Prepare a Helm values file to provide your customizations. To get started, you can use the minimum settings in the following profile as a basis. These settings enable all components that are required for a Gloo data plane installation.
      curl https://storage.googleapis.com/gloo-platform/helm-profiles/$GLOO_VERSION/gloo-core-agent.yaml > data-plane.yaml
open data-plane.yaml

  5. Depending on the method you chose to secure the relay connection, prepare the Helm values for the data plane installation. For more information, see the Setup options.

    1. Make sure that the following Kubernetes secrets exist in the gloo-mesh namespace on each workload cluster.

      • relay-root-tls-secret that holds the root CA certificate
      • relay-identity-token-secret that holds the relay identity token value
      • telemetry-root-secret that holds the root CA certificate for the certificate chain

      You can use the steps in BYO server certificate with managed client certificate as a guidance for how to create these secrets in the workload cluster.

    2. In your Helm values file for the agent, add the following values.
