\n\n# Prometheus Helm Chart\n\nPrometheus is a monitoring system and time series database. The Prometheus Helm chart automates deployment and configuration of Prometheus in Kubernetes clusters using Minimus images.\n\n\n## {{icon-list-search}} Prerequisites\n\n- A subscription to the Minimus images included in the chart\n- A running Kubernetes cluster (v1.19 or higher is recommended)\n- `kubectl` installed and configured\n- Helm v3.8 or higher for OCI support ([Installation instructions](https://helm.sh/docs/intro/install/))\n- Cluster Admin privileges\n\n

\n\n---\n\n

\n\n## {{icon-rocket}}Try It Out\n\nIn this example we will deploy Prometheus on a Kubernetes cluster using the Minimus Prometheus Helm chart. Prometheus will provide a full monitoring stack with metric collection, alerting, and visualization out of the box.\n\n

\n\n### Step 1: Start Cluster\n\n

\n\nIf you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. [Deployment instructions](https://minikube.sigs.k8s.io/docs/start/?arch=%2Flinux%2Fx86-64%2Fstable%2Fbinary+download)\n\n

\n\n### Step 2: Create Secret\n\n

\n\nFirst, create a namespace:\n\n```\nkubectl create ns prometheus\n```\n\nNext, create a Kubernetes secret for the Minimus token so Helm will be able to pull images from the Minimus registry:\n\n```\nkubectl create secret docker-registry minimus-registry \\\n --docker-server=reg.mini.dev \\\n --docker-username=minimus \\\n --docker-password={{pull-token}} \\\n --namespace=prometheus\n```\n\n

\n\n### Step 3: Deploy the Helm Chart\n\n

\n\nDeploy the Minimus Helm chart:\n\n```\nhelm install my-prometheus {{oci-url}} \\\n -n prometheus \\\n --wait\n```\n\nIf you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using `-f values.yaml`:\n\n```\nhelm install my-prometheus {{oci-url}} \\\n -f values.yaml \\\n -n prometheus \\\n --wait\n```\n\n

\n\n### Step 4: Verify Prometheus is Running\n\n

\n\nConfirm the chart deployed successfully and all components started:\n\n```\nkubectl get pods -n prometheus\n```\n\nYou should see output similar to:\n\n```\nNAME READY STATUS RESTARTS AGE\nmy-prometheus-server-xxxxxxxxx-xxxxx 2/2 Running 0 2m\nmy-prometheus-prometheus-alertmanager-0 1/1 Running 0 2m\nmy-prometheus-kube-state-metrics-xxxxxxxxx-xxxxx 1/1 Running 0 2m\nmy-prometheus-prometheus-node-exporter-xxxxx 1/1 Running 0 2m\nmy-prometheus-prometheus-pushgateway-xxxxxxxxx-xxxxx 1/1 Running 0 2m\n```\n\n

\n\n### Step 5: Test HTTP Endpoint\n\n

\n\nForward the Prometheus server port to your local machine:\n\n```\nkubectl port-forward svc/my-prometheus-server 9090:80 -n prometheus\n```\n\nIn another terminal, verify the health endpoint responds:\n\n```\ncurl -sf http://localhost:9090/-/healthy\n```\n\nYou should see:\n\n```\nPrometheus Server is Healthy.\n```\n\nQuery the Prometheus API to confirm metric collection is working:\n\n```\ncurl -s http://localhost:9090/api/v1/query?query=up | jq '.data.result | length'\n```\n\nA non-zero result confirms Prometheus is actively scraping targets.\n\n

\n\n### Step 6: Clean Up\n\n

\n\nUninstall the chart and delete the namespace to remove all resources:\n\n```bash\nhelm uninstall my-prometheus -n prometheus\nkubectl delete namespace prometheus\n```\n\n

\n\n# kube-prometheus-stack Helm Chart\n\nkube-prometheus-stack collects Kubernetes manifests, Grafana dashboards, and Prometheus rules combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with Prometheus using the Prometheus Operator. The kube-prometheus-stack Helm chart automates deployment and configuration of the Prometheus monitoring stack in Kubernetes clusters using Minimus images.\n\n\n## {{icon-list-search}} Prerequisites\n\n- A subscription to the Minimus images included in the chart\n- A running Kubernetes cluster (v1.25 or higher is recommended)\n- `kubectl` installed and configured\n- Helm v3.8 or higher for OCI support ([Installation instructions](https://helm.sh/docs/intro/install/))\n- Cluster Admin privileges\n\n**Note**: kube-prometheus-stack installs CRDs (Custom Resource Definitions) for Prometheus, Alertmanager, ServiceMonitors, PodMonitors, and related Prometheus Operator resources. Installing these CRDs requires cluster-admin privileges.\n\n

\n\n---\n\n

\n\n## {{icon-rocket}}Try It Out\n\nIn this example we will deploy the Prometheus monitoring stack on a Kubernetes cluster using the Minimus kube-prometheus-stack Helm chart. Out of the box you get Prometheus, Alertmanager, Grafana, node-exporter, kube-state-metrics, and the Prometheus Operator, wired together for end-to-end cluster monitoring.\n\n

\n\n### Step 1: Start Cluster\n\n

\n\n### Step 2: Create Namespace\n\n

\n\nCreate a namespace:\n\n```\nkubectl create ns kube-prometheus-stack\n```\n\n{{if-enterprise}}\n\nNext, create a Kubernetes secret for the Minimus token:\n\n```\nkubectl create secret docker-registry minimus-registry \\\n --docker-server=reg.mini.dev \\\n --docker-username=minimus \\\n --docker-password={{pull-token}} \\\n --namespace=kube-prometheus-stack\n```\n\n{{/if-enterprise}}\n\n

\n\n### Step 3: Deploy the Helm Chart\n\n

\n\nDeploy the Minimus Helm chart:\n\n```\nhelm install my-kube-prometheus-stack {{oci-url}} \\\n --version {{chart-version}} \\\n -n kube-prometheus-stack \\\n --wait\n```\n\nIf you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using `-f values.yaml`:\n\n```\nhelm install my-kube-prometheus-stack {{oci-url}} \\\n --version {{chart-version}} \\\n -f values.yaml \\\n -n kube-prometheus-stack \\\n --wait\n```\n\n

\n\n### Step 4: Verify kube-prometheus-stack is Running\n\n

\n\nConfirm the chart deployed successfully and all components started:\n\n```\nkubectl get pods -n kube-prometheus-stack\n```\n\nYou should see output similar to:\n\n```\nNAME READY STATUS RESTARTS AGE\nmy-kube-prometheus-stack-grafana-xxxxxxxxx-xxxxx 3/3 Running 0 2m\nmy-kube-prometheus-stack-kube-state-metrics-xxxxxxxxx-xxxxx 1/1 Running 0 2m\nmy-kube-prometheus-stack-operator-xxxxxxxxx-xxxxx 1/1 Running 0 2m\nmy-kube-prometheus-stack-prometheus-node-exporter-xxxxx 1/1 Running 0 2m\nalertmanager-my-kube-prometheus-stack-alertmanager-0 2/2 Running 0 2m\nprometheus-my-kube-prometheus-stack-prometheus-0 2/2 Running 0 2m\n```\n\n

\n\n### Step 5: Test the Monitoring Stack\n\n

\n\nPort-forward to the Prometheus service and confirm it is healthy:\n\n```\nkubectl port-forward svc/my-kube-prometheus-stack-prometheus -n kube-prometheus-stack 9090:9090\n```\n\nIn another terminal, query the health endpoint — it should return `Prometheus Server is Healthy.`:\n\n```\ncurl -sf http://localhost:9090/-/healthy\n```\n\nYou can also reach the Grafana dashboards. Port-forward the Grafana service:\n\n```\nkubectl port-forward svc/my-kube-prometheus-stack-grafana -n kube-prometheus-stack 3000:80\n```\n\nOpen `http://localhost:3000` and log in as `admin`. Retrieve the password with:\n\n```\nkubectl -n kube-prometheus-stack get secret my-kube-prometheus-stack-grafana -o jsonpath=\"{.data.admin-password}\" | base64 -d\n```\n\n

\n\n### Step 6: Clean Up\n\n

\n\nUninstall the chart and delete the namespace to remove all resources:\n\n```\nhelm uninstall my-kube-prometheus-stack -n kube-prometheus-stack\nkubectl delete namespace kube-prometheus-stack\n```\n\n
