Discovery also finds Kubernetes events and frequently updates the CMDB to reflect the dynamic Kubernetes environment. Discovery uses the Kubernetes pattern and its extension sections to discover Kubernetes components: - The **Collect OpenShift info** extension section of the Kubernetes pattern discovers the OpenShift components of the Kubernetes deployment. The OpenShift Build Config extension section is available from Store version 1.0.53. - The **Service Mesh** extension discovers service mesh details. This information enables the pattern to create service-to-service relations, shown as Connects to::Connected. Service mesh discovery requires deploying Istio on your K8s \(Kubernetes\) cluster. The Service Mesh extension section is available from [Kubernetes extension classes](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/cmdb-ci-class-models-kubernetes.md). It’s supported on the ServiceNow AI Platform using the Madrid release or later. - The **Collect Container Repository** and extension section finds container registries and images in these registries. Starting from Discovery and Service Mapping Patterns version 1.35.0, the Kubernetes Cluster - Per-Namespace LP pattern is available for large cluster discovery. For more information, see the **Large-payload Kubernetes discovery** section. In addition, Discovery uses the Kubernetes Event pattern to discover events for Kubernetes components. Starting from the 1.0.68 release on ServiceNow Store, Service Mapping can use CI relationships to add the Kubernetes components to application services during tag-based discovery. Discovery uses the following patterns to discover the entire Kubernetes infrastructure deployed on GCP, AWS, and Azure: - Google Cloud Platform \(GCP\) – Get Kubernetes Clusters. - Amazon AWS Cloud - Get Kubernetes Clusters. - Microsoft Azure - Get Kubernetes Clusters. These patterns query the Cloud, collect data on all Kubernetes clusters, and create a serverless schedule for each cluster. When the cluster is deleted, the schedule is marked as inactive. This feature eliminates the overhead of creating and managing multiple credentials and serverless discovery schedules per cluster. The Cloud infrastructure patterns are triggered through standard Cloud discovery. Starting with Discovery and Service Mapping Patterns version 1.31.0, you can choose to discover Docker image CIs only, without discovering Docker container CIs. Check your entitlements to determine whether you have access to 2026 Packaging SKU. For more information, see [Disable Docker container CI discovery](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/disable-docker-container-discovery.md). ## Supported versions For the list of Kubernetes distribution versions validated against the Kubernetes and Kubernetes Event patterns, see [Kubernetes Versions Tested with ServiceNow Discovery \[KB3145280\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB3145280). ## Request apps on the Store Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html). ## Large-payload Kubernetes discovery By default, Discovery uses the Kubernetes pattern to discover an entire cluster in a single execution. On large clusters, this can result in incomplete discovery data in the CMDB. The Kubernetes Cluster - Per-Namespace LP pattern is available as an alternative for large cluster environments, starting from Discovery and Service Mapping Patterns version 1.35.0. The Kubernetes Cluster - Per-Namespace LP pattern identifies the cluster and then discovers each namespace separately, improving reliability on large clusters. The data collected and the CIs populated in the CMDB are identical between the two patterns. For configuration on on-premises clusters, see the **Prerequisites for on-premises Kubernetes discovery** section. For cloud clusters, see the prerequisites section for your cloud provider. ## General prerequisites for Kubernetes discovery **Note:** For additional prerequisites for Kubernetes Cloud infrastructure discovery, see [below](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/kubernetes-discovery.md). **Note:** Running automatic serverless Kubernetes schedules fetches the Bearer token. Adding credentials is unnecessary. Perform the following steps so that Discovery can use the pattern to successfully find Kubernetes. 1. Deploy the latest Discovery and Service Mapping Patterns application from ServiceNow Store. 2. On the Kubernetes platform, find the parameters to set up Kubernetes discovery: - Find the URL of the kubeapi server: 1. On the Kubernetes platform, run the following command: `kubectl cluster-info` 2. In the output, find the line that states the URL of the kubeapi server. For example, Kubernetes control plane is running at `https://10.154.144.146:443` - Find the namespaces of the kubeapi server: 1. On the Kubernetes platform, run this command: `kubectl get namespaces` 2. In the output, find the line that states the namespaces. For example, `kube-system`. - Find the Kubernetes username and password: 1. On the Kubernetes platform, run this command: `kubectl config view` 2. In the output, find the username and password.\[Omitted image "kubernetes-username-password.png"\] Alt text: Locate the lines that contain information on password and username. **Note:** If in a certain environment, `kubectl config view` command is not showing the expected details, use the `supported` command from the Kubernetes admin to fetch the user name and password details. - Find the valid Bearer token with the proper permissions: - If you know the default token name, use the command in the following format: `kubectl describe secret `. For example: `kubectl describe secret default-token-g6pwc`. - If you don't know the default token name, use the command: `kubectl describe secret`. 3. Verify that the API Server is reachable from the MID Server for successful Kubernetes discovery. 4. Verify that the user configured on the Kubernetes platform has **GET** permissions to run the following /api/v1 elements: - https://<url>/api/v1/namespaces/ - https://<url>/api/v1/namespaces/<namespace> - https://<url>/api/v1/namespaces/kube-system/endpoints/kube-controller-manager - https://<url>/api/v1/services - https://<url>/api/v1/pods - https://<url>/api/v1/nodes - https://<url>/api/v1/replicationcontrollers - https://<url>/apis/networking.k8s.io/v1/ingresses - https://<url>/apis/apps/v1/deployments - https://<url>/apis/apps/v1/statefulsets - https://<url>/apis/apps/v1/daemonsets - https://<url>/apis/apps/v1/replicasets - https://<url>/apis/batch/v1/cronjobs - https://<url>/apis/batch/v1/jobs **Note:** When using the **Kubernetes Cluster - Per-Namespace LP** pattern, verify your RBAC setup before switching. The LP pattern requires the same permissions listed above, but lists resources per namespace instead of cluster-wide. A ClusterRole with a ClusterRoleBinding covers all namespaces automatically and requires no changes. If you use namespace-scoped Role and RoleBinding objects, verify that a binding exists in each namespace that discovery will enumerate, because missing bindings could cause incomplete discovery for that namespace. 5. To discover the OpenShift components of the Kubernetes deployment, verify that the user configured on the Kubernetes platform has **GET** permissions to run the following /api/v1 elements: - /apis/apps.openshift.io/v1/deploymentconfigs - ​/apis/build.openshift.io/v1/buildconfigs​ - /apis/route.openshift.io/v1/routes​ - /apis/user.openshift.io/v1/groups​ - /apis/user.openshift.io/v1/users​ - /apis/project.openshift.io/v1/projects​ - /apis/image.openshift.io/v1/images​ - /apis/image.openshift.io/v1/imagestreams To discover service mesh information: - Deploy Istio on your K8s cluster. - Provide the Prometheus URL. - Configure Prometheus to scrape metrics from Istio. 6. Activate **Get Kubernetes Config Files** extension to: - Discover configuration files. - Create tracked configuration files. - Map the configuration files workloads and services with a relationship. **Note:** Tracked files content is in the JSON format from version 1.0.92. Tracked files content is in YAML format in version 1.0.91 and earlier. 7. Create the Kubernetes credentials on the ServiceNow platform: 1. On the ServiceNow AI Platform, navigate to **All** > **Discovery** > **Credentials**. 2. Select **New**. 3. Select **Kubernetes Credentials**. 4. On the form, fill in the fields.
Field Description
Name Unique and descriptive name for this credential.
User name User name associated with this credential. Leading or trailing spaces should be avoided; if any are detected, a warning will appear. Only one authentication method should be used: either a user name and password or a Bearer token. Don't use both.
Password Password associated with this credential. Only one authentication method should be used: either a user name and password or a Bearer token. Don't use both.
Bearer Token Authentication This option enables advanced authentication using a Bearer token. When the check box is selected, the Bearer Token field is displayed.
Bearer Token Discovery uses the Bearer token for advanced authentication when accessing Kubernetes. The Bearer token should be in BASE64 encoded format, using the character sequence as the token. For example: 31ada4fd-adec-460c-809a-9e56ceb75269. Only one authentication method should be used: either a user name and password or a Bearer token. Don't use both.
Credential alias An alias is configured to use the Kubernetes credential for devices and applications other than Kubernetes. This alias is also used when defining a serverless discovery schedule for discovering the Kubernetes deployment.1. Select the padlock icon, and then select the search icon. 2. On the Connection & Credential Aliases form, select **New**. 3. Specify a name for the credential alias record. 4. Define attributes for the alias. Set the **Type** to `Credential`. 5. Select and hold \(or right-click\) the form header and select **Save**, then select **Update**. 6. On the Connection & Credential Aliases form, select the newly added alias. The alias appears in the Credential alias field.
5. On the Kubernetes credentials form, select **Update**. 8. Create a serverless discovery schedule for the Kubernetes pattern. 1. Navigate to **All** > **Discovery** > **Discovery Schedules** and select **New**. 2. On the form, fill in the fields.
Field Description

cluster\_uid\_cache Internal parameter used by the **Kubernetes Cluster - Per-Namespace LP** pattern. Leave this value empty.
9. Create a serverless discovery schedule for the Kubernetes Event pattern. Configure the schedule to run every 5 or 10 minutes. **Note:** When the pattern is run for the first time, it stores an event\_timestamp. Later on it collects only the delta events based on the timestamp. The more often the pattern is run, the fewer updates to the CMDB IRE are needed. Create a serverless execution pattern for the discovery schedule and assign it to the Kubernetes Events pattern. Configure the parameters required by the Kubernetes pattern as described in [Configuring execution pattern attributes](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/kubernetes-discovery.md). 10. To include discovered components into service instances, enable CI relationships used in tag-based discovery by Service Mapping. These CI relationships are available from the 1.0.68 release on the ServiceNow Store. For operational steps, see [Tag-based discovery configuration](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/service-mapping/tag_discovery_configuration.md). ## Additional prerequisites for Kubernetes Cloud infrastructure discovery For the Google Cloud Platform \(GCP\) – Get Kubernetes Clusters pattern, perform the following: 1. In the ServiceNow instance, set up a Google Cloud Platform \(GCP\) service account with valid credentials and permissions. 2. On the GCP infrastructure, set up the MID Server with full access to all Cloud APIs: Set Cloud API access scopes to "Allow full access to all Cloud APIs". The MID Server instance can access only the Clusters specific to the project. 3. Navigate to `sys_properties.list` and, using the admin role, configure the following properties: - **sn\_itom\_pattern.k8s\_midserver**: Specify a valid MID Server or MID Server cluster name \(MID Server cluster support starting with Discovery and Service Mapping Patterns version 1.35.0\). **Note:** To target a specific service account or cluster, you can configure the **sn\_itom\_pattern.k8s\_<service\_account\_id>\_midserver** and the **sn\_itom\_pattern.k8s\_<service\_account\_id>\_<clustername>\_midserver** properties. The most specific property takes precedence. - **sn\_itom\_pattern.k8s\_create\_schedule\_enabled**: Set the value to **true**. **Note:** Enabling the **sn\_itom\_pattern.k8s\_create\_schedule\_enabled** property automatically creates a serverless schedule for your cloud clusters, eliminating the need for manual scheduling. If you have an existing manual schedule and want to convert it to an automatic one, enable the property. Your manual schedule will be updated; no additional schedule will be created. An automatically created schedule has no "Max run time" defined. - **sn\_itom\_pattern.k8s\_entry\_pattern**: To use the per-namespace large-payload \(LP\) discovery pattern, set the value to **Kubernetes Cluster - Per-Namespace LP** \(starting from Discovery and Service Mapping Patterns version 1.35.0\). 4. Create and run Google Cloud Discovery **Note:** To fetch the Bearer token, while running GKE Kubernetes schedule, use the gcloud command: `gcloud config config-helper --format="value(credential.access_token)"` Configuring gcloud in the MID Server instance grants access to the GKE cluster to fetch the token. For the Amazon Elastic Kubernetes Service \(EKS\) cluster discovery, perform the following: 1. In the ServiceNow instance, set an AWS service account with valid management account credentials and permissions. 1. Verify that the Amazon Elastic Kubernetes Service \(EKS\) Cluster has a cluster role with the read-only access to all resources. 2. Create cluster role binding between the cluster role and a Kubernetes user. For example, read-onlyuser. 3. Create an AWS IAM role with the policy EKSReadOnly. 4. Associate the IAM role with the Kubernetes user in one of the following ways: - In the cluster, edit the aws-auth ConfigMap. - Run the command: `eksctl create iamidentitymapping --cluster yourClusterName --arnarn:aws:iam::yourAccountID:role/yourIAMRoleName --username read-only-user` 2. Run Amazon Elastic Kubernetes Service \(EKS\) cluster discovery in one of two ways: Using the AWS Command Line Interface \(CLI\) or without using the AWS CLI. First, set the system property **sn\_itom\_pattern.k8s\_aws\_cli\_to\_generate\_token** to use the model you choose. This system property is set to **true** by default. - Set this system property to **true** to use AWS CLI to generate a token. - Set this system property to **false** to use Assume Roles to generate a token. 1. Run Amazon Elastic Kubernetes Service \(EKS\) cluster discovery using AWS CLI: 1. Set up the MID Server with the AWS CLI configured. Configuring AWS CLI credentials grants access to the Amazon Elastic Kubernetes Service \(EKS\) cluster. **Note:** The user logged in to the system must be the same as the MID Server user. 2. To generate the Bearer token, While running the Amazon Elastic Kubernetes Service \(EKS\) schedule, use the AWS CLI command:`aws eks get-token --cluster-name `. Configuring the AWS CLI user/role in the MID Server instance grants access to the Amazon Elastic Kubernetes Service \(EKS\) cluster to generate the token. 2. Run Amazon Elastic Kubernetes Service \(EKS\) cluster discovery without using AWS CLI: **Note:** This feature is supported from Discovery and Service Mapping Patterns version 1.0.96 - December 2022. Refer to the following KB for detailed instructions: [KB1182188: EKS cluster discovery using STS AssumeRoles \(Without AWS CLI\)](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1182188) 3. Navigate to `sys_properties.list` and, using the admin role, configure the following properties: - **sn\_itom\_pattern.k8s\_midserver**: Specify a valid MID Server or MID Server cluster name \(MID Server cluster support starting with Discovery and Service Mapping Patterns version 1.35.0\). **Note:** To target a specific service account or cluster, you can configure the **sn\_itom\_pattern.k8s\_<service\_account\_id>\_midserver** and the **sn\_itom\_pattern.k8s\_<service\_account\_id>\_<clustername>\_midserver** properties. The most specific property takes precedence. - **sn\_itom\_pattern.k8s\_create\_schedule\_enabled**: Set the value to **true**. **Note:** Enabling the **sn\_itom\_pattern.k8s\_create\_schedule\_enabled** property automatically creates a serverless schedule for your cloud clusters, eliminating the need for manual scheduling. If you have an existing manual schedule and want to convert it to an automatic one, enable the property. Your manual schedule will be updated; no additional schedule will be created. An automatically created schedule has no "Max run time" defined. - **sn\_itom\_pattern.k8s\_entry\_pattern**: To use the per-namespace large-payload \(LP\) discovery pattern, set the value to **Kubernetes Cluster - Per-Namespace LP** \(starting from Discovery and Service Mapping Patterns version 1.35.0\). 4. Create and run an AWS Cloud Discovery schedule. For Microsoft Azure Kubernetes Services \(AKS\)- Kubernetes cluster discovery, perform the following: 1. Update to the latest Discovery and Service Mapping Patterns version. 2. In the ServiceNow instance, configure the Azure Service Account with valid Azure credentials and permission. 3. Navigate to `sys_properties.list` and, using the admin role, configure the following properties: - **sn\_itom\_pattern.k8s\_midserver**: Specify a valid MID Server or MID Server cluster name \(MID Server cluster support starting with Discovery and Service Mapping Patterns version 1.35.0\). **Note:** To target a specific service account or cluster, you can configure the **sn\_itom\_pattern.k8s\_<service\_account\_id>\_midserver** and the **sn\_itom\_pattern.k8s\_<service\_account\_id>\_<clustername>\_midserver** properties. The most specific property takes precedence. - **sn\_itom\_pattern.k8s\_create\_schedule\_enabled**: Set the value to **true**. **Note:** Enabling the **sn\_itom\_pattern.k8s\_create\_schedule\_enabled** property automatically creates a serverless schedule for your cloud clusters, eliminating the need for manual scheduling. If you have an existing manual schedule and want to convert it to an automatic one, enable the property. Your manual schedule will be updated; no additional schedule will be created. An automatically created schedule has no "Max run time" defined. . - **sn\_itom\_pattern.k8s\_entry\_pattern**: To use the per-namespace large-payload \(LP\) discovery pattern, set the value to **Kubernetes Cluster - Per-Namespace LP** \(starting from Discovery and Service Mapping Patterns version 1.35.0\). 4. If you don't have local accounts with Kubernetes RBAC and want to improve pattern efficiency, navigate to **MID Server** > **Properties** and set the **sn\_itom\_pattern.aks\_fetch\_local\_ad\_token** property to **false**. 5. Run an Azure cloud discovery schedule. 6. Configure the MID Server in the Discovery schedules according to the cluster account type. If you don't have Local accounts with RBAC, you can ignore this step.
Cluster account type Discovery schedule MID Server
MS Entra ID auth with Kubernetes RBAC. Any MID Server.
MS Entra ID authentication with Azure RBAC. Any MID Server.
Local accounts with Kubernetes RBAC. Select the MID Server with the Azure Command Line Interface \(CLI\) configured. Configuring the Azure CLI credentials grants access to the AKS cluster. To fetch the Bearer token while running the AKS Kubernetes schedule, use the Azure CLI command: `az aks get-credentials --name --overwrite-existing --resource-group --file -`.
**Note:** - The user logged in to the system must be the same as the MID Server user. - For detailed information about AKS Cluster Discovery configuration, see the [AKS Cluster Discovery Configuration Details \[KB1220553\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1220553) article in the Now Support Knowledge Base.

To use the enhanced Kubernetes dashboard, verify you have Discovery Admin Workspace starting from version 1.3.1 \(August 2024 Store\). For more information about Kubernetes Explorer, see [Kubernetes Explorer](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/cloud-discovery-workspace/cloud-operations-workspace-kubernetes-dashboard.md). ## Troubleshooting If the mapping process does not proceed as you expected, follow the following suggestions.
Symptom Cause Solution
Discovery fails. The discovery message contains the information about an error caused by the REST timeout. There are many CIs sending the REST call response in the deployment. The MID Server cannot process the REST call response without exceeding the time limit controlled by the **mid.sa.cloud.request\_timeout** parameter. By default, the **mid.sa.cloud.request\_timeout** parameter is set to 30000 milliseconds. Increase the value of this parameter on the relevant MID Server and run discovery again. **Note:** If the **Configuration Parameters** related list for the relevant MID Server does not show this parameter, you may need to add it.
Pattern Designer fails during a debug session. The Pattern Designer message contains information about an error caused by a timeout. The Pattern Designer fails because of a timeout during pattern debugging \(and not during discovery\). By default, the **sa.debugger.max\_timeout**parameter is set to 240 seconds.Increase the value of this parameter on the relevant MID Server.
To run the Kubernetes pattern in Debug mode, refer to [KB0832567](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0832567) for operational information. - **[Container image scanning for software decomposition](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/container-image-concept.md)** The ITOM Visibility apps, Discovery and Service Mapping Patterns and Kubernetes Visibility Agent integrate with Aqua Trivy to collect data on container images and OS packages. You can increase your control over container deployment by having visibility to the container components. **Parent Topic:**[Discovery for containerized resources](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/container-discovery.md)
