In Gloo Mesh version 2.7 and later, Solo has a new way of installing Istio with the Gloo Operator.

Use Gloo Platform to install Istio ingress, egress, and east-west gateways in your workload clusters, as part of the Istio lifecycle management. In your GatewayLifecycleManager resource, you provide gateway settings in an IstioOperator configuration. When you create the GatewayLifecycleManager in your management cluster, Gloo translates the configuration into gateways in your registered workload clusters for you.

For more information, see the Install Istio by using the Istio Lifecycle Manager guide.

Examples

East-west: This example creates an east-west gateway named istio-eastwestgateway in the gloo-mesh-gateways namespace of two workload clusters ($REMOTE_CLUSTER1 and $REMOTE_CLUSTER2). You supply the repo key for the Solo distribution of Istio (hub: $REPO), image tag (tag: $ISTIO_IMAGE), and revision (revision: $REVISION). Note that for advanced east-west traffic routing across multiple clusters, you need a Gloo Mesh Enterprise license.

GatewayClusterSelector

Clusters to install the Istio gateways in.

Field	Description
`name`	(`string`) Name of the cluster to install the gateway into. Must match the name of the cluster that you used when you registered the cluster with Gloo.
`activeGateway`	(`bool`) Optional: Defaults to false. When set to true, the gateway installation for this revision is applied as the active gateway through which primary service traffic is routed in the cluster. If the `istioOperatorSpec` defines a service, this field switches the service selectors to the revision specified in the `gatewayRevsion`. You might change this setting for gateway installations during a canary upgrade. For more info, see the upgrade docs.
`trustDomain`	(`string`) Optional: By default, the `trustDomain` value in the `meshConfig` section of the operator spec is automatically set by the Gloo to the name of each workload cluster. To override the `trustDomain` for each cluster, you can instead specify the override value by using this `trustDomain` field, and include the value in the list of cluster names. For example, if you specify `meshConfig.trustDomain: cluster1-trust-override` in your operator spec, you then specify both the cluster name (`name: cluster1`) and the trust domain (`trustDomain: cluster1-trust-override`) in this `installations.clusters` section. Additionally, because Gloo requires multiple trust domains for east-west routing, the `PILOT_SKIP_VALIDATE_TRUST_DOMAIN` field is set to `"true"` by default. For more info, see the Istio documentation.

GatewayInstallation

List of Istio gateway installations. Any components that are not related to the gateway are ignored. You can provide only one type of gateway installation per revision in a cluster. For example, in a workload cluster cluster2, you can install only one east-west gateway that runs revision 1-19-5.

Field	Description
`controlPlaneRevision`	(`string`) Optional: The revision of an Istio control plane in the cluster that this gateway should also use. If a control plane installation of this revision is not found, no gateway is created.
`gatewayRevision`	(`string`) Istio revision for this gateway installation. When set to `auto`, Gloo installs the gateway with the default supported version of the Solo distribution of Istio.
`clusters`	(`repeated GatewayClusterSelector`) Clusters to install the Istio gateways in.
`istioOperatorSpec`	(`common.gloo.solo.io.IstioOperatorSpec`) IstioOperator specification for the gateway. For more info, see the Istio documentation.
`skipUpgradeValidation`	(`bool`) When set to true, the lifecycle manager allows you to perform in-place upgrades by skipping checks that are required for canary upgrades. In production environments, canary upgrades are recommended for updating the minor version. To update the patch version or make configuration changes within the same version, you can use in-place upgrades. Be sure to test in-place upgrades in development or staging environments first.
