\n\n# cert-manager Helm Chart\n\ncert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. The cert-manager Helm chart automates deployment and configuration of cert-manager in Kubernetes clusters using the Minimus cert-manager 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 (v1.22 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**: cert-manager uses Custom Resource Definitions (CRDs) for Certificates, Issuers, and related resources. You can install CRDs by adding `--set cert-manager.crds.enabled=true` to your `helm install` command, or install them separately from the [cert-manager releases](https://github.com/cert-manager/cert-manager/releases).\n\n

\n\n---\n\n

\n\n## {{icon-rocket}}Try It Out\n\nIn this example we will deploy cert-manager on a Kubernetes cluster using the Minimus cert-manager Helm chart. cert-manager will provide automated TLS certificate management for your Kubernetes workloads.\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 cert-manager\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=cert-manager\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-cert-manager {{oci-url}} \\\n --version {{chart-version}} \\\n --set cert-manager.crds.enabled=true \\\n -n cert-manager \\\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-cert-manager {{oci-url}} \\\n --version {{chart-version}} \\\n -f values.yaml \\\n --set cert-manager.crds.enabled=true \\\n -n cert-manager \\\n --wait\n```\n\n

\n\n### Step 4: Verify cert-manager is Running\n\n

\n\nConfirm the chart deployed successfully and cert-manager started:\n\n```\nkubectl get pods -n cert-manager\n```\n\nYou should see output similar to:\n\n```\nNAME READY STATUS RESTARTS AGE\nmy-cert-manager-xxxxxxxxx-xxxxx 1/1 Running 0 2m\nmy-cert-manager-cainjector-xxxxxxxxx-xxxxx 1/1 Running 0 2m\nmy-cert-manager-webhook-xxxxxxxxx-xxxxx 1/1 Running 0 2m\n```\n\n

\n\n### Step 5: Test Certificate Issuance\n\n

\n\nCreate a self-signed issuer and a test certificate to verify cert-manager is working:\n\n```\ncat <\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-cert-manager -n cert-manager\nkubectl delete namespace cert-manager\n```\n\n
