API Schema definitions for configuring the installation of Calico and Calico Enterprise

Resource Types:

- Installation
- TigeraStatus

### Installation

Installation configures an installation of Calico or Calico Enterprise. At most one instance of this resource is supported. It must be named “default”. The Installation API installs core networking and network policy components, and provides general install-time configuration.

Field | Description
--- | ---
`apiVersion` string | `operator.tigera.io/v1`
`kind` string | `Installation`
`metadata` Kubernetes meta/v1.ObjectMeta | Refer to the Kubernetes API documentation for the fields of the `metadata` field.
`spec` InstallationSpec | Specification of the desired state for the Calico or Calico Enterprise installation.
`variant` ProductVariant | (Optional) Variant is the product to install - one of Calico or TigeraSecureEnterprise Default: Calico
`registry` string | (Optional) Registry is the default Docker registry used for component Docker images. If specified, all images will be pulled from this registry. If not specified then the default registries will be used. Image format: `<registry>/<imagePath>/<imageName>:<image-tag>` This option allows configuring the `<registry>` portion of the above format.
`imagePath` string | (Optional) ImagePath allows for the path part of an image to be specified. If specified then the specified value will be used as the image path for each image. If not specified or empty, the default for each image will be used. Image format: `<registry>/<imagePath>/<imageName>:<image-tag>` This option allows configuring the `<imagePath>` portion of the above format.
`imagePullSecrets` []Kubernetes core/v1.LocalObjectReference | (Optional) ImagePullSecrets is an array of references to container registry pull secrets to use. These are applied to all images to be pulled.
`kubernetesProvider` Provider | (Optional) KubernetesProvider specifies a particular provider of the Kubernetes platform and enables provider-specific configuration. If the specified value is empty, the Operator will attempt to automatically determine the current provider. If the specified value is not empty, the Operator will still attempt auto-detection, but will additionally compare the auto-detected value to the specified value to confirm they match.
`calicoNetwork` CalicoNetworkSpec | (Optional) CalicoNetwork specifies configuration options for Calico provided pod networking.
`clusterManagementType` ClusterManagementType | (Optional) How the cluster is managed. Valid values for this field are: Standalone, Management, Managed. Standalone clusters are fully self-contained installations of Calico Enterprise. Management clusters provide a single view to manage any number of Managed clusters, which are a lighter weight installation. This option is applicable only when variant is TigeraSecureEnterprise. Default: Standalone
`controlPlaneNodeSelector` map[string]string | (Optional) ControlPlaneNodeSelector is used to select control plane nodes on which to run specific Calico components. This currently only applies to kube-controllers and the apiserver.
`nodeMetricsPort` int32 | (Optional) NodeMetricsPort specifies which port calico/node serves prometheus metrics on. By default, metrics are not enabled. If specified, this overrides any FelixConfiguration resources which may exist. If omitted, then prometheus metrics may still be configured through FelixConfiguration.
`flexVolumePath` string | (Optional) FlexVolumePath optionally specifies a custom path for FlexVolume. If not specified, FlexVolume will be enabled by default. If set to ‘None’, FlexVolume will be disabled. The default is based on the kubernetesProvider.
`nodeUpdateStrategy` Kubernetes apps/v1.DaemonSetUpdateStrategy | (Optional) NodeUpdateStrategy can be used to customize the desired update strategy, such as the MaxUnavailable field.
`componentResources` []*github.com/tigera/operator/pkg/apis/operator/v1.ComponentResource | (Optional) ComponentResources can be used to customize the resource requirements for each component.
`status` InstallationStatus | Most recently observed state for the Calico or Calico Enterprise installation.
