Helm Chart for the F5 Container Ingress Services

This chart simplifies repeatable, versioned deployment of the Container Ingress Services.

Prerequisites

• Refer to CIS Prerequisites to install Container Ingress Services on Kubernetes or Openshift
• Helm 3 should be installed.

Installing CIS Using Helm Charts

This is the simplest way to install the CIS on OpenShift/Kubernetes cluster. Helm is a package manager for Kubernetes. Helm is Kubernetes version of yum or apt. Helm deploys something called charts, which you can think of as a packaged application. It is a collection of all your versioned, pre-configured application resources which can be deployed as one unit. This chart creates a Deployment for one Pod containing the k8s-bigip-ctlr, it's supporting RBAC, Service Account and Custom Resources Definition installations.

Installing the Chart

• Add BIG-IP credentials as K8S secrets.

For Kubernetes, use the following command:

kubectl create secret generic f5-bigip-ctlr-login -n kube-system --from-literal=username=admin --from-literal=password=<password>

For OpenShift, use the following command:

oc create secret generic f5-bigip-ctlr-login -n kube-system --from-literal=username=admin --from-literal=password=<password>

• Add the CIS chart repository in Helm using following command:

helm repo add f5-stable https://f5networks.github.io/charts/stable

• Create values.yaml as shown in examples:

• Install the Helm chart using the following command:

helm install -f values.yaml <new-chart-name> f5-stable/f5-bigip-ctlr

• Install the Helm chart with skip crds (without custom resource definitions installations)

helm install --skip-crds -f values.yaml <new-chart-name> f5-stable/f5-bigip-ctlr

See the CIS documentation for a full list of args supported for CIS CIS Configuration Options

Note: Helm value names cannot include the character - which is commonly used in the names of parameters passed to the controller. To accomodate Helm, the parameter names in values.yaml use _ and then replace them with - when rendering. e.g. args.bigip_url is rendered as bigip-url as required by the CIS Controller.

If you have a specific use case for F5 products in the Kubernetes environment that would benefit from a curated chart, please open an issue describing your use case and providing example resources.

Uninstalling Helm Chart

Run the following command to uninstall the chart.

helm uninstall <new-chart-name>
