IstioLifecycleManager

IstioLifecycleManager API reference.

Proto: istio_lifecycle_manager.proto

Package: admin.gloo.solo.io

check_circle

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 control planes in your workload clusters, as part of the Istio lifecycle management. In your IstioLifecycleManager resource, you provide istiod settings in an IstioOperator configuration. When you create the IstioLifecycleManager in your management cluster, Gloo translates the configuration into istiod control planes in your registered workload clusters for you.

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

Example

This example creates an istiod control plane in the istio-system 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).

IstioClusterSelector

Clusters to install the Istio control planes in.

Field	Description
`name`	(`string`) Name of the cluster to install Istio into. Must match the name of the cluster that you used when you registered the cluster with Gloo.
`defaultRevision`	(`bool`) Optional: Defaults to false. When set to true, the installation for this revision is applied as the active Istio installation in the cluster. Resources with the `istio-injection=true` label entry use this revision. You might change this setting for Istio 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.

IstioController

Field	Description
`waitForResourcesTimeout`	(`string`) The amount of time to wait for resources in a component to become ready before giving up. Configured using a duration string. A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as “300ms” or “2h45m”. Valid time units are “ns”, “us” (or “µs”), “ms”, “s”, “m”, “h”.
`imagePullSecrets`	(`repeated k8s.io.api.core.v1.LocalObjectReference`) Names of image pull secrets to use to deploy the Istio controller. For more info, see the Kubernetes docs.
`resources`	(`common.gloo.solo.io.Resources`) Override for resources allocated to the Istio controller deployment. For more info, see the Kubernetes docs.
`securityContext`	(`k8s.io.api.core.v1.SecurityContext`) Override for the pod’s security context. For more info, see the Kubernetes documentation.
`labels`	(`repeated IstioController.LabelsEntry`) Kubernetes pod/deployment/service labels.
`annotations`	(`repeated IstioController.AnnotationsEntry`) Kubernetes pod/deployment/service annotations.
`envVars`	(`repeated k8s.io.api.core.v1.EnvVar`) Deployment environment variables. For more info, see the Kubernetes docs.

IstioController.AnnotationsEntry

Field	Description
`key`	(`string`)
`value`	(`string`)

IstioController.LabelsEntry

Field	Description
`key`	(`string`)
`value`	(`string`)

IstioInstallation

List of Istio control plane installations. Any components that are NOT related to the control plane are ignored.

Field	Description
`revision`	(`string`) Istio revision for this installation. Label workload resources with ‘istio.io/rev=$REVISION’ to use this installation. When set to `auto`, Gloo installs the control plane with the default supported version of the Solo distribution of Istio. **Configuration constraints: This value can be a maximum of 63 characters.
`clusters`	(`repeated IstioClusterSelector`) Clusters to install the Istio control planes in.
`istioOperatorSpec`	(`common.gloo.solo.io.IstioOperatorSpec`) IstioOperator specification for the control plane. For more info, see the Istio documentation.
`istioController`	(`IstioController`) Optional configuration to tune the deployment of the IstioOperator controller deployed to each workload cluster.
`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.
