WARNING: This feature was [deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5. GitLab provides several ways to integrate applications to your Kubernetes cluster. To enable cluster integrations, first add a Kubernetes cluster to a GitLab [project](../project/clusters/add_remove_clusters.md) or [group](../group/clusters/index.md) or [instance](../instance/clusters/index.md). You can install your applications manually as shown in the following sections, or use the [Cluster management project template](management_project_template.md) that automates the installation. Although, the [Cluster management project template](management_project_template.md) still requires that you manually do the last steps of these sections, [Enable Prometheus integration for your cluster](#enable-prometheus-integration-for-your-cluster) or [Enable Elastic Stack integration for your cluster](#enable-elastic-stack-integration-for-your-cluster) depending on which application you are installing. [An issue exists](https://gitlab.com/gitlab-org/gitlab/-/issues/326565) to automate this step. Prometheus and Elastic Stack cluster integrations can only be enabled for clusters [connected through cluster certificates](../project/clusters/add_existing_cluster.md). To enable Prometheus for your cluster connected through the [GitLab Kubernetes Agent](agent/index.md), you can [integrate it manually](../project/integrations/prometheus.md#manual-configuration-of-prometheus). There is no option to enable Elastic Stack for your cluster if it is connected with the GitLab Kubernetes Agent. Follow this [issue](https://gitlab.com/gitlab-org/gitlab/-/issues/300230) for updates. ## Prometheus cluster integration > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/55244) in GitLab 13.11. WARNING: This feature was [deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5. However, you can **still use** Prometheus for Kubernetes clusters connected to GitLab through the [GitLab Kubernetes Agent](agent/index.md) by [enabling Prometheus manually](../project/integrations/prometheus.md#manual-configuration-of-prometheus). You can integrate your Kubernetes cluster with [Prometheus](https://prometheus.io/) for monitoring key metrics of your apps directly from the GitLab UI. Once enabled, you can see metrics from services available in the [metrics library](../project/integrations/prometheus_library/index.md). ### Prometheus Prerequisites To use this integration: 1. Prometheus must be installed in your cluster in the `gitlab-managed-apps` namespace. 1. The `Service` resource for Prometheus must be named `prometheus-prometheus-server`. You can manage your Prometheus however you like, but as an example, you can set it up using [Helm](https://helm.sh/) as follows: ```shell # Create the required Kubernetes namespace kubectl create ns gitlab-managed-apps # Download Helm chart values that is compatible with the requirements above. # These are included in the Cluster Management project template. wget https://gitlab.com/gitlab-org/project-templates/cluster-management/-/raw/master/applications/prometheus/values.yaml # Add the Prometheus community Helm chart repository helm repo add prometheus-community https://prometheus-community.github.io/helm-charts # Install Prometheus helm install prometheus prometheus-community/prometheus -n gitlab-managed-apps --values values.yaml ``` Alternatively, you can use your preferred installation method to install Prometheus as long as you meet the requirements above. ### Enable Prometheus integration for your cluster To enable the Prometheus integration for your cluster: 1. Go to the cluster's page: - For a [project-level cluster](../project/clusters/index.md), navigate to your project's **Infrastructure > Kubernetes clusters**. - For a [group-level cluster](../group/clusters/index.md), navigate to your group's **Kubernetes** page. - For an [instance-level cluster](../instance/clusters/index.md), navigate to your instance's **Kubernetes** page. 1. Select the **Integrations** tab. 1. Check the **Enable Prometheus integration** checkbox. 1. Click **Save changes**. 1. Go to the **Health** tab to see your cluster's metrics. ## Elastic Stack cluster integration > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/61077) in GitLab 13.12. You can integrate your cluster with [Elastic Stack](https://www.elastic.co/elastic-stack/) to index and [query your pod logs](../project/clusters/kubernetes_pod_logs.md). ### Elastic Stack Prerequisites To use this integration: 1. Elasticsearch 7.x or must be installed in your cluster in the `gitlab-managed-apps` namespace. 1. The `Service` resource must be called `elastic-stack-elasticsearch-master` and expose the Elasticsearch API on port `9200`. 1. The logs are expected to be [Filebeat container logs](https://www.elastic.co/guide/en/beats/filebeat/7.x/filebeat-input-container.html) following the [7.x log structure](https://www.elastic.co/guide/en/beats/filebeat/7.x/exported-fields-log.html) and include [Kubernetes metadata](https://www.elastic.co/guide/en/beats/filebeat/7.x/add-kubernetes-metadata.html). You can manage your Elastic Stack however you like, but as an example, you can use [this Elastic Stack chart](https://gitlab.com/gitlab-org/charts/elastic-stack) to get up and running: ```shell # Create the required Kubernetes namespace kubectl create namespace gitlab-managed-apps # Download Helm chart values that is compatible with the requirements above. # These are included in the Cluster Management project template. wget https://gitlab.com/gitlab-org/project-templates/cluster-management/-/raw/master/applications/elastic-stack/values.yaml # Add the GitLab Helm chart repository helm repo add gitlab https://charts.gitlab.io # Install Elastic Stack helm install elastic-stack gitlab/elastic-stack -n gitlab-managed-apps --values values.yaml ``` ### Enable Elastic Stack integration for your cluster To enable the Elastic Stack integration for your cluster: 1. Go to the cluster's page: - For a [project-level cluster](../project/clusters/index.md), navigate to your project's **Infrastructure > Kubernetes clusters**. - For a [group-level cluster](../group/clusters/index.md), navigate to your group's **Kubernetes** page. - For an [instance-level cluster](../instance/clusters/index.md), navigate to your instance's **Kubernetes** page. 1. Select the **Integrations** tab. 1. Check the **Enable Elastic Stack integration** checkbox. 1. Click **Save changes**. 1. Go to the **Health** tab to see your cluster's metrics.
