Table 1. Development environment configuration options.
Property	Description
defaultComponents	Default components applied to DevWorkspaces. These default components are meant to be used when a Devfile, that does not contain any components.
defaultEditor	The default editor to workspace create with. It could be a plugin ID or a URI. The plugin ID must have `publisher/plugin/version` format. The URI must start from `http://` or `https://`.
defaultNamespace	User’s default namespace.
defaultPlugins	Default plug-ins applied to DevWorkspaces.
nodeSelector	The node selector limits the nodes that can run the workspace pods.
storage	Workspaces persistent storage.
tolerations	The pod tolerations of the workspace pods limit where the workspace pods can run.
trustedCerts	Trusted certificate settings.

Table 2. Che components configuration.
Property	Description
cheServer	General configuration settings related to the Che server.
dashboard	Configuration settings related to the dashboard used by the Che installation.
database	Configuration settings related to the database used by the Che installation.
devWorkspace	DevWorkspace Operator configuration.
devfileRegistry	Configuration settings related to the devfile registry used by the Che installation.
imagePuller	Kubernetes Image Puller configuration.
metrics	Che server metrics configuration.
pluginRegistry	Configuration settings related to the plug-in registry used by the Che installation.

Table 3. DevWorkspace operator component configuration.
Property	Description
deployment	Deployment override options.
runningLimit	The maximum number of running workspaces per user.

Table 4. General configuration settings related to the Che server component.
Property	Description
clusterRoles	ClusterRoles assigned to Che ServiceAccount. The defaults roles are: - `<che-namespace>-cheworkspaces-namespaces-clusterrole` - `<che-namespace>-cheworkspaces-clusterrole` - `<che-namespace>-cheworkspaces-devworkspace-clusterrole` where the <che-namespace> is the namespace where the CheCluster CRD is created. Each role must have a `app.kubernetes.io/part-of=che.eclipse.org` label. The Che Operator must already have all permissions in these ClusterRoles to grant them.
debug	Enables the debug mode for Che server.
deployment	Deployment override options.
extraProperties	A map of additional environment variables applied in the generated `che` ConfigMap to be used by the Che server in addition to the values already generated from other fields of the `CheCluster` custom resource (CR). If the `extraProperties` field contains a property normally generated in `che` ConfigMap from other CR fields, the value defined in the `extraProperties` is used instead.
logLevel	The log level for the Che server: `INFO` or `DEBUG`.
proxy	Proxy server settings for Kubernetes cluster. No additional configuration is required for OpenShift cluster. By specifying these settings for the OpenShift cluster, you override the OpenShift proxy configuration.

Table 5. Configuration settings related to the Plug-in registry component used by the Che installation.
Property	Description
deployment	Deployment override options.
disableInternalRegistry	Disables internal plug-in registry.
externalPluginRegistries	External plugin registries.

Table 6. Configuration settings related to the Devfile registry component used by the Che installation.
Property	Description
deployment	Deployment override options.
disableInternalRegistry	Disables internal devfile registry.
externalDevfileRegistries	External devfile registries serving sample ready-to-use devfiles.

Table 7. Configuration settings related to the Database component used by the Che installation.
Property	Description
credentialsSecretName	The secret that contains PostgreSQL `user` and `password` that the Che server uses to connect to the database. The secret must have a `app.kubernetes.io/part-of=che.eclipse.org` label.
deployment	Deployment override options.
externalDb	Instructs the Operator to deploy a dedicated database. By default, a dedicated PostgreSQL database is deployed as part of the Che installation. When `externalDb` is set as `true`, no dedicated database is deployed by the Operator and you need to provide connection details about the external database you want to use.
postgresDb	PostgreSQL database name that the Che server uses to connect to the database.
postgresHostName	PostgreSQL database hostname that the Che server connects to. Override this value only when using an external database. See field `externalDb`.
postgresPort	PostgreSQL Database port the Che server connects to. Override this value only when using an external database. See field `externalDb`.
pvc	PVC settings for PostgreSQL database.

Table 8. Configuration settings related to the Dashboard component used by the Che installation.
Property	Description
deployment	Deployment override options.
headerMessage	Dashboard header message.

Table 9. Kubernetes Image Puller component configuration.
Property	Description
enable	Install and configure the community supported Kubernetes Image Puller Operator. When you set the value to `true` without providing any specs, it creates a default Kubernetes Image Puller object managed by the Operator. When you set the value to `false`, the Kubernetes Image Puller object is deleted, and the Operator uninstalled, regardless of whether a spec is provided. If you leave the `spec.images` field empty, a set of recommended workspace-related images is automatically detected and pre-pulled after installation. Note that while this Operator and its behavior is community-supported, its payload may be commercially-supported for pulling commercially-supported images.
spec	A Kubernetes Image Puller spec to configure the image puller in the CheCluster.

Table 10. Che server metrics component configuration.
Property	Description
enable	Enables `metrics` for the Che server endpoint.

Table 11. Networking, Che authentication and TLS configuration.
Property	Description
annotations	Defines annotations which will be set for an Ingress (a route for OpenShift platform). The defaults for kubernetes platforms are: kubernetes.io/ingress.class: \nginx\ nginx.ingress.kubernetes.io/proxy-read-timeout: \3600\, nginx.ingress.kubernetes.io/proxy-connect-timeout: \3600\, nginx.ingress.kubernetes.io/ssl-redirect: \true\
auth	Authentication settings.
domain	For an OpenShift cluster, the Operator uses the domain to generate a hostname for the route. The generated hostname follows this pattern: che-<che-namespace>.<domain>. The <che-namespace> is the namespace where the CheCluster CRD is created. In conjunction with labels, it creates a route served by a non-default Ingress controller. For a Kubernetes cluster, it contains a global ingress domain. There are no default values: you must specify them.
hostname	The public hostname of the installed Che server.
labels	Defines labels which will be set for an Ingress (a route for OpenShift platform).
tlsSecretName	The name of the secret used to set up Ingress TLS termination. If the field is an empty string, the default cluster certificate is used. The secret must have a `app.kubernetes.io/part-of=che.eclipse.org` label.

Table 12. Configuration of an alternative registry that stores Che images.
Property	Description
hostname	An optional hostname or URL of an alternative container registry to pull images from. This value overrides the container registry hostname defined in all the default container images involved in a Che deployment. This is particularly useful for installing Che in a restricted environment.
organization	An optional repository name of an alternative registry to pull images from. This value overrides the container registry organization defined in all the default container images involved in a Che deployment. This is particularly useful for installing Che in a restricted environment.

Table 13. `CheCluster` Custom Resource `status` defines the observed state of Che installation
Property	Description
chePhase	Specifies the current phase of the Che deployment.
cheURL	Public URL of the Che server.
cheVersion	Currently installed Che version.
devfileRegistryURL	The public URL of the internal devfile registry.
gatewayPhase	Specifies the current phase of the gateway deployment.
message	A human readable message indicating details about why the Che deployment is in the current phase.
pluginRegistryURL	The public URL of the internal plug-in registry.
postgresVersion	The PostgreSQL version of the image in use.
reason	A brief CamelCase message indicating details about why the Che deployment is in the current phase.
workspaceBaseDomain	The resolved workspace base domain. This is either the copy of the explicitly defined property of the same name in the spec or, if it is undefined in the spec and we’re running on OpenShift, the automatically resolved basedomain for routes.
