\n\n# Fluentd Helm Chart\n\nFluentd is a popular open-source data collector that unifies the collection and consumption of data from various sources and destinations. The Fluentd Helm chart automates deployment and configuration of Fluentd 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 (v1.21 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 Fluentd on a Kubernetes cluster using the Minimus Fluentd Helm chart. Fluentd will collect container logs from your cluster nodes and expose Prometheus metrics.\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 Namespace\n\n

\n\nCreate a namespace:\n\n```\nkubectl create ns fluentd\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=fluentd\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-fluentd {{oci-url}} \\\n --version {{chart-version}} \\\n -n fluentd \\\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-fluentd {{oci-url}} \\\n --version {{chart-version}} \\\n -f values.yaml \\\n -n fluentd \\\n --wait\n```\n\n

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

\n\nConfirm the chart deployed successfully and Fluentd started:\n\n```\nkubectl get pods -n fluentd -l app.kubernetes.io/name=fluentd\n```\n\nYou should see output similar to:\n\n```\nNAME READY STATUS RESTARTS AGE\nmy-fluentd-xxxxx 1/1 Running 0 2m\n```\n\n

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

\n\nVerify Fluentd is collecting metrics by port-forwarding to the metrics port:\n\n```\nkubectl port-forward -n fluentd daemonset/my-fluentd 24231:24231\n```\n\nIn another terminal, check the Prometheus metrics endpoint:\n\n```\ncurl -sf http://localhost:24231/metrics\n```\n\nYou should see Prometheus-format metrics output including `fluentd_input_status_num_records_total` and other Fluentd metrics.\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-fluentd -n fluentd\nkubectl delete namespace fluentd\n```\n\n
