Che WebSocket major internal endpoint. Provides basic communication endpoint for major WebSocket interactions and messaging.

Your projects are synchronized from the Che server into the machine running each workspace. This is the directory in the machine where your projects are placed.

Used when Kubernetes-type components in a devfile request project PVC creation (Applied in case of unique and per workspace PVC strategy. In case of the common PVC strategy, it is rewritten with the value of the che.infra.kubernetes.pvc.quantity property.)

Defines the directory inside the machine where all the workspace logs are placed. Provide this value into the machine, for example, as an environment variable. This is to ensure that agent developers can use this directory to back up agent logs.

Configures environment variable HTTP_PROXY to a specified value in containers powering workspaces.

Configures environment variable HTTPS_PROXY to a specified value in containers powering workspaces.

Configures environment variable NO_PROXY to a specified value in containers powering workspaces.

By default, when users access a workspace with its URL, the workspace automatically starts (if currently stopped). Set this to false to disable this behavior.

Workspace threads pool configuration. This pool is used for workspace-related operations that require asynchronous execution, for example, starting and stopping. Possible values are fixed and cached.

This property is ignored when pool type is different from fixed. It configures the exact size of the pool. When set, the multiplier property is ignored. If this property is not set (0, <0, NULL), then the pool size equals the number of cores. See also che.workspace.pool.cores_multiplier.

This property is ignored when pool type is not set to fixed, che.workspace.pool.exact_size is set. When set, the pool size is N_CORES * multiplier.

This property specifies how many threads to use for workspace server liveness probes.

RAM request for each container that has no explicit RAM settings in its environment. This amount is allocated when the workspace container is created. This property may not be supported by all infrastructure implementations. Currently it is supported by Kubernetes. A memory request exceeding the memory limit is ignored, and only the limit size is used. Value less or equal to 0 is interpreted as disabling the limit.

CPU limit for each container that has no CPU settings in its environment. Specify either in floating point cores number, for example, 0.125, or using the Kubernetes format, integer millicores, for example, 125m. Value less or equal to 0 is interpreted as disabling the limit.

CPU request for each container that has no CPU settings in environment. A CPU request exceeding the CPU limit is ignored, and only limit number is used. Value less or equal to 0 is interpreted as disabling the limit.

RAM limit for each sidecar that has no RAM settings in the Che plug-in configuration. Value less or equal to 0 is interpreted as disabling the limit.

RAM request for each sidecar that has no RAM settings in the Che plug-in configuration.

CPU limit default for each sidecar that has no CPU settings in the Che plug-in configuration. Specify either in floating point cores number, for example, 0.125, or using the Kubernetes format, integer millicores, for example, 125m. Value less or equal to 0 is interpreted as disabling the limit.

CPU request default for each sidecar that has no CPU settings in the Che plug-in configuration. Specify either in floating point cores number, for example, 0.125, or using the Kubernetes format, integer millicores, for example, 125m.

Defines image-pulling strategy for sidecars. Possible values are: Always, Never, IfNotPresent. For any other value, Always is assumed for images with the :latest tag, or IfNotPresent for all other cases.

Period of inactive workspaces suspend job execution.

The period of the cleanup of the activity table. The activity table can contain invalid or stale data if some unforeseen errors happen, as a server failure at a peculiar point in time. The default is to run the cleanup job every hour.

If true, 'stop-workspace' role with the edit privileges will be granted to the 'che' ServiceAccount if OpenShift OAuth is enabled. This configuration is mainly required for workspace idling when the OpenShift OAuth is enabled.

Specifies whether Che is deployed with DevWorkspaces enabled. This property is set by the Che Operator if it also installed the support for DevWorkspaces. This property is used to advertise this fact to the Che dashboard. It does not make sense to change the value of this property manually.

Che has a single identity implementation, so this does not change the user experience. If true, enables user creation at API level

Defines the way how servers are exposed to the world in Kubernetes infra. List of strategies implemented in Che: default-host, multi-host, single-host.

Defines the way in which the workspace plugins and editors are exposed in the single-host mode. Supported exposures: native: Exposes servers using Kubernetes Ingresses. Works only on Kubernetes. gateway: Exposes servers using reverse-proxy gateway.

Defines the way how to expose devfile endpoints, as end-user’s applications, in single-host server strategy. They can either follow the single-host strategy and be exposed on subpaths, or they can be exposed on subdomains. multi-host: expose on subdomains single-host: expose on subpaths

Defines labels which will be set to ConfigMaps configuring single-host gateway.

Used to generate domain for a server in a workspace in case property che.infra.kubernetes.server_strategy is set to multi-host

Indicates whether Che server is allowed to create namespace for user workspaces, or they’re intended to be created manually by cluster administrator. This property is also used by the OpenShift infra.

Defines Kubernetes default namespace in which user’s workspaces are created if user does not override it. It’s possible to use <username> and <userid> placeholders (for example: che-workspace-<username>). In that case, new namespace will be created for each user. Used by OpenShift infra as well to specify a Project. The <username> or <userid> placeholder is mandatory.

Defines whether che-server should try to label the workspace namespaces.

Defines whether che-server should try to annotate the workspace namespaces.

List of labels to find namespace that are used for Che Workspaces. They are used to: - find prepared namespace for users in combination with che.infra.kubernetes.namespace.annotations. - actively label namespace with any workspace.

List of annotations to find namespace prepared for Che users workspaces. Only namespace matching the che.infra.kubernetes.namespace.labels will be matched against these annotations. namespace that matches both che.infra.kubernetes.namespace.labels and che.infra.kubernetes.namespace.annotations will be preferentially used for User’s workspaces. It’s possible to use <username> placeholder to specify the namespace to concrete user. They are used to: - find prepared namespace for users in combination with che.infra.kubernetes.namespace.labels. - actively annotate namespace with any workspace.

Defines Kubernetes Service Account name which should be specified to be bound to all workspaces Pods. the Che Operator that Kubernetes Infrastructure will not create the service account and it should exist. OpenShift infrastructure will check if project is predefined(if che.infra.openshift.project is not empty): - if it is predefined then service account must exist there - if it is 'NULL' or empty string then infrastructure will create new OpenShift project per workspace and prepare workspace service account with needed roles there

Specifies optional, additional cluster roles to use with the workspace service account. the Che Operator that the cluster role names must already exist, and the Che service account needs to be able to create a Role Binding to associate these cluster roles with the workspace service account. The names are comma separated. This property deprecates che.infra.kubernetes.cluster_role_name.

Cluster roles to assign to user in his namespace

Defines wait time that limits the Kubernetes workspace start time.

Defines the timeout in minutes that limits the period for which Kubernetes Ingress become ready

If during workspace startup an unrecoverable event defined in the property occurs, stop the workspace immediately rather than waiting until timeout. the Che Operator that this SHOULD NOT include a mere "Failed" reason, because that might catch events that are not unrecoverable. A failed container startup is handled explicitly by Che server.

Defines whether use the Persistent Volume Claim for Che workspace needs, for example: backup projects, logs, or disable it.

Defined which strategy will be used while choosing PVC for workspaces. Supported strategies: common: All workspaces in the same namespace will reuse the same PVC. Name of PVC may be configured with che.infra.kubernetes.pvc.name. Existing PVC will be used or a new one will be created if it does not exist. unique: Separate PVC for each workspace’s volume will be used. Name of PVC is evaluated as '{che.infra.kubernetes.pvc.name} + '-' + {generated_8_chars}'. Existing PVC will be used or a new one will be created if it does not exist. per-workspace: Separate PVC for each workspace will be used. Name of PVC is evaluated as '{che.infra.kubernetes.pvc.name} + '-' + {WORKSPACE_ID}'. Existing PVC will be used or a new one will be created if it doesn’t exist.

Defines whether to run a job that creates workspace’s subpath directories in persistent volume for the common strategy before launching a workspace. Necessary in some versions of Kubernetes as workspace subpath volume mounts are created with root permissions, and therefore cannot be modified by workspaces running as a user (presents an error importing projects into a workspace in Che). The default is true, but should be set to false if the version of Kubernetes creates subdirectories with user permissions. See: subPath in volumeMount is not writable for non-root users #41638 the Che Operator that this property has effect only if the common PVC strategy used.

Defines the settings of PVC name for Che workspaces. Each PVC strategy supplies this value differently. See documentation for che.infra.kubernetes.pvc.strategy property

Defines the storage class of Persistent Volume Claim for the workspaces. Empty strings means "use default".

Defines the size of Persistent Volume Claim of Che workspace. See: Understanding persistent storage

Pod that is launched when performing persistent volume claim maintenance jobs on OpenShift

Image pull policy of container that used for the maintenance jobs on Kubernetes cluster

Defines Pod memory limit for persistent volume claim maintenance jobs

Defines Persistent Volume Claim access mode. the Che Operator that for common PVC strategy changing of access mode affects the number of simultaneously running workspaces. If the OpenShift instance running Che is using Persistent Volumes with RWX access mode, then a limit of running workspaces at the same time is bounded only by Che limits configuration: RAM, CPU, and so on. See: Understanding persistent storage

Defines if Che Server should wait workspaces Persistent Volume Claims to become bound after creating. Default value is true. The parameter is used by all Persistent Volume Claim strategies. It should be set to false when volumeBindingMode is configured to WaitForFirstConsumer otherwise workspace starts will hangs up on phase of waiting PVCs.

Defines annotations for ingresses which are used for servers exposing. Value depends on the kind of ingress controller. OpenShift infrastructure ignores this property because it uses Routes rather than Ingresses. the Che Operator that for a single-host deployment strategy to work, a controller supporting URL rewriting has to be used (so that URLs can point to different servers while the servers do not need to support changing the app root). The che.infra.kubernetes.ingress.path.rewrite_transform property defines how the path of the ingress should be transformed to support the URL rewriting and this property defines the set of annotations on the ingress itself that instruct the chosen ingress controller to actually do the URL rewriting, potentially building on the path transformation (if required by the chosen ingress controller). For example for Nginx ingress controller 0.22.0 and later the following value is recommended: {"ingress.kubernetes.io/rewrite-target": "/$1","ingress.kubernetes.io/ssl-redirect": "false",\ "ingress.kubernetes.io/proxy-connect-timeout": "3600","ingress.kubernetes.io/proxy-read-timeout": "3600", "nginx.org/websocket-services": "<service-name>"} and the che.infra.kubernetes.ingress.path.rewrite_transform should be set to "%s(.*)". For nginx ingress controller older than 0.22.0, the rewrite-target should be set to merely / and the path transform to %s (see the che.infra.kubernetes.ingress.path.rewrite_transform property). See the Nginx ingress controller documentation for the explanation of how the ingress controller uses the regular expression available in the ingress path and how it achieves the URL rewriting.

Defines a recipe on how to declare the path of the ingress that should expose a server. The %s represents the base public URL of the server and is guaranteed to end with a forward slash. This property must be a valid input to the String.format() method and contain exactly one reference to %s. See the description of the che.infra.kubernetes.ingress.annotations_json property to see how these two properties interplay when specifying the ingress annotations and path. If not defined, this property defaults to %s (without the quotes) which means that the path is not transformed in any way for use with the ingress controller.

Additional labels to add into every Ingress created by Che server to allow clear identification.

Defines security context for Pods that will be created by Kubernetes Infra This is ignored by OpenShift infra

Defines security context for Pods that will be created by Kubernetes Infra. A special supplemental group that applies to all containers in a Pod. This is ignored by OpenShift infra.

Defines grace termination period for Pods that will be created by Kubernetes infrastructures. Default value: 0. It allows to stop Pods quickly and significantly decrease the time required for stopping a workspace. the Che Operator: if terminationGracePeriodSeconds have been explicitly set in Kubernetes recipe it will not be overridden.

Number of maximum concurrent asynchronous web requests (HTTP requests or ongoing WebSocket calls) supported in the underlying shared HTTP client of the KubernetesClient instances. Default values: max=64, and max_per_host:5. Default values are not suitable for multi-user scenarios, as Che keeps open connections, for example for command or ws-agent logs.

Number of maximum concurrent asynchronous web requests per host.

Max number of idle connections in the connection pool of the Kubernetes-client shared HTTP client.

Keep-alive timeout of the connection pool of the Kubernetes-client shared HTTP client in minutes.

Creates Ingresses with Transport Layer Security (TLS) enabled. In OpenShift infrastructure, Routes will be TLS-enabled.

Name of a secret that should be used when creating workspace ingresses with TLS. This property is ignored by OpenShift infrastructure.

Data for TLS Secret that should be used for workspaces Ingresses. cert and key should be encoded with Base64 algorithm. These properties are ignored by OpenShift infrastructure.

Certificate data for TLS Secret that should be used for workspaces Ingresses. Certificate should be encoded with Base64 algorithm. This property is ignored by OpenShift infrastructure.

Defines the period with which runtimes consistency checks will be performed. If runtime has inconsistent state then runtime will be stopped automatically. Value must be more than 0 or -1, where -1 means that checks won’t be performed at all. It is disabled by default because there is possible Che Server configuration when Che Server doesn’t have an ability to interact with Kubernetes API when operation is not invoked by user. It DOES work on the following configurations: - workspaces objects are created in the same namespace where Che Server is located; - cluster-admin service account token is mounted to Che Server Pod. It DOES NOT work on the following configurations: - Che Server communicates with Kubernetes API using token from OAuth provider.

Name of the ConfigMap in Che server namespace with additional CA TLS certificates to be propagated into all user’s workspaces. If the property is set on OpenShift 4 infrastructure, and che.infra.openshift.trusted_ca.dest_configmap_labels includes the config.openshift.io/inject-trusted-cabundle=true label, then cluster CA bundle will be propagated too.

Name of the ConfigMap in a workspace namespace with additional CA TLS certificates. Holds the copy of che.infra.kubernetes.trusted_ca.src_configmap but in a workspace namespace. Content of this ConfigMap is mounted into all workspace containers including plugin brokers. Do not change the ConfigMap name unless it conflicts with the already existing ConfigMap. the Che Operator that the resulting ConfigMap name can be adjusted eventually to make it unique in namespace. The original name would be stored in che.original_name label.

Configures path on workspace containers where the CA bundle should be mounted. Content of ConfigMap specified by che.infra.kubernetes.trusted_ca.dest_configmap is mounted.

Comma separated list of labels to add to the CA certificates ConfigMap in user workspace. See the che.infra.kubernetes.trusted_ca.dest_configmap property.

Comma separated list of labels to add to the CA certificates ConfigMap in user workspace. See che.infra.kubernetes.trusted_ca.dest_configmap property. This default value is used for automatic cluster CA bundle injection in OpenShift 4.

Additional labels to add into every Route created by Che server to allow clear identification.

The hostname that should be used as a suffix for the workspace routes. For example: Using domain_suffix=<che-host>, the route resembles: routed3qrtk.<che-host>. It has to be a valid DNS name.

Initialize OpenShift project with Che server’s service account if OpenShift OAuth is enabled.

Docker image of Che plugin broker app that resolves workspace tools configuration and copies plugins dependencies to a workspace. The Che Operator overrides these images by default. Changing the images here will not have an effect if Che is installed using the Operator.

Docker image of Che plugin artifacts broker. This broker runs as an init container on the workspace Pod. Its job is to take in a list of plugin identifiers (either references to a plugin in the registry or a link to a plugin meta.yaml) and ensure that the correct .vsix and .theia extensions are downloaded into the /plugins directory, for each plugin requested for the workspace.

Configures the default behavior of the plugin brokers when provisioning plugins into a workspace. If set to true, the plugin brokers will attempt to merge plugins when possible: they run in the same sidecar image and do not have conflicting settings. This value is the default setting used when the devfile does not specify the mergePlugins attribute.

Devfile Registry "internal" endpoint. Should be a valid HTTP URL. Example: http://plugin-registry.che.svc.cluster.local:8080 In case Che plug-ins registry is not needed value 'NULL' should be used

The configuration property that defines available values for storage types that clients such as the Dashboard should propose to users during workspace creation and update. Available values: - persistent: Persistent Storage slow I/O but persistent. - ephemeral: Ephemeral Storage allows for faster I/O but may have limited storage and is not persistent. - async: Experimental feature: Asynchronous storage is combination of Ephemeral and Persistent storage. Allows for faster I/O and keep your changes, will backup on stop and restore on start workspace. Will work only if: - che.infra.kubernetes.pvc.strategy='common' - che.limits.user.workspaces.run.count=1 - che.infra.kubernetes.namespace.default contains <username> in other cases remove async from the list.

The configuration property that defines a default value for storage type that clients such as the Dashboard should propose to users during workspace creation and update. The async value is an experimental feature, not recommended as default type.

Configures in which way secure servers will be protected with authentication. Suitable values: - default: jwtproxy is configured in a pass-through mode.

Default Plug-ins which should be provisioned for Default Editor. All the plugins from this list that are not explicitly mentioned in the user-defined devfile will be provisioned but only when the default editor is used or if the user-defined editor is the same as the default one (even if in different version). Format is comma-separated pluginPublisher/pluginName/pluginVersion values, and URLs.

Address of the GitLab server with configured OAuth 2 integration

System Super Privileged Mode. Grants users with the manageSystem permission additional permissions for getByKey, getByNameSpace, stopWorkspaces, and getResourcesInformation. These are not given to admins by default and these permissions allow admins gain visibility to any workspace along with naming themselves with administrator privileges to those workspaces.

Grant system permission for che.admin.name user. If the user already exists it’ll happen on component startup, if not - during the first login when user is persisted in the database.

Workspaces are the fundamental runtime for users when doing development. You can set parameters that limit how workspaces are created and the resources that are consumed. The maximum amount of RAM that a user can allocate to a workspace when they create a new workspace. The RAM slider is adjusted to this maximum value.

The length of time in milliseconds that a user is idle with their workspace when the system will suspend the workspace and then stopping it. Idleness is the length of time that the user has not interacted with the workspace, meaning that one of the agents has not received interaction. Leaving a browser window open counts toward idleness.

The length of time in milliseconds that a workspace will run, regardless of activity, before the system will suspend it. Set this property if you want to automatically stop workspaces after a period of time. The default is zero, meaning that there is no run timeout.

The total amount of RAM that a single user is allowed to allocate to running workspaces. A user can allocate this RAM to a single workspace or spread it across multiple workspaces.

The maximum number of workspaces that a user is allowed to create. The user will be presented with an error message if they try to create additional workspaces. This applies to the total number of both running and stopped workspaces.

The maximum number of running workspaces that a single user is allowed to have. If the user has reached this threshold and they try to start an additional workspace, they will be prompted with an error message. The user will need to stop a running workspace to activate another.

The total amount of RAM that a single organization (team) is allowed to allocate to running workspaces. An organization owner can allocate this RAM however they see fit across the team’s workspaces.

The maximum number of workspaces that a organization is allowed to own. The organization will be presented an error message if they try to create additional workspaces. This applies to the total number of both running and stopped workspaces.

The maximum number of running workspaces that a single organization is allowed. If the organization has reached this threshold and they try to start an additional workspace, they will be prompted with an error message. The organization will need to stop a running workspace to activate another.

Alias of the OpenShift identity provider registered in Keycloak, that should be used to create workspace OpenShift resources in OpenShift namespaces owned by the current Che user. Should be set to NULL if che.infra.openshift.project is set to a non-empty value. See: OpenShift identity provider

Url to OIDC identity provider server Can be set to NULL only if che.oidc.oidcProvider is used

Internal network service Url to OIDC identity provider server

The number of seconds to tolerate for clock skew when verifying exp or nbf claims.

Username claim to be used as user display name when parsing JWT token if not defined the fallback value is 'preferred_username' in Keycloak installations and name in Dex installations.

Base URL of an alternate OIDC provider that provides a discovery endpoint as detailed in the following specification Obtaining OpenID Provider Configuration Information Deprecated, use che.oidc.auth_server_url and che.oidc.auth_internal_server_url instead.

Keycloak realm is used to authenticate users Can be set to NULL only if che.keycloak.oidcProvider is used

Keycloak client identifier in che.keycloak.realm to authenticate users in the dashboard, the IDE, and the CLI.

URL to access OSO OAuth tokens

URL to access Github OAuth tokens

Use the OIDC optional nonce feature to increase security.

URL to the Keycloak Javascript adapter to use. if set to NULL, then the default used value is ${che.keycloak.auth_server_url}/js/keycloak.js, or <che-server>/api/keycloak/OIDCKeycloak.js if an alternate oidc_provider is used

Set to true when using an alternate OIDC provider that only supports fixed redirect Urls This property is ignored when che.keycloak.oidc_provider is NULL

Configuration of OAuth Authentication Service that can be used in "embedded" or "delegated" mode. If set to "embedded", then the service work as a wrapper to Che’s OAuthAuthenticator ( as in Single User mode). If set to "delegated", then the service will use Keycloak IdentityProvider mechanism. Runtime Exception wii be thrown, in case if this property is not set properly.

Configuration for enabling removing user from Keycloak server on removing user from Che database. By default it’s disabled. Can be enabled in some special cases when deleting a user in Che database should execute removing related-user from Keycloak. For correct work need to set administrator username ${che.keycloak.admin_username} and password ${che.keycloak.admin_password}.

Keycloak administrator username. Will be used for deleting user from Keycloak on removing user from Che database. Make sense only in case ${che.keycloak.cascade_user_removal_enabled} set to 'true'

Keycloak administrator password. Will be used for deleting user from Keycloak on removing user from Che database. Make sense only in case ${che.keycloak.cascade_user_removal_enabled} set to 'true'

User name adjustment configuration. Che needs to use the usernames as part of Kubernetes object names and labels and therefore has stricter requirements on their format than the identity providers usually allow (it needs them to be DNS-compliant). The adjustment is represented by comma-separated key-value pairs. These are sequentially used as arguments to the String.replaceAll function on the original username. The keys are regular expressions, values are replacement strings that replace the characters in the username that match the regular expression. The modified username will only be stored in the Che database and will not be advertised back to the identity provider. It is recommended to use DNS-compliant characters as replacement strings (values in the key-value pairs). Example: \\=-,@=-at- changes \ to - and @ to -at- so the username org\user@com becomes org-user-at-com.
