Enabling preinstalled Calico might be the quickest way for testing. However, if you like to checkout a more recent version or features of Calico you should consider using Manifest or Operator approach.

  1. minikube start --network-plugin=cni --cni=calico
  1. Start your minikube cluster with one control plane node using the following command.

If 192.168.0.0/16 is already in use within your network you must select a different pod network CIDR, by replacing 192.168.0.0/16 in the following command.

  1. minikube start --cni=false --network-plugin=cni --extra-config=kubeadm.pod-network-cidr=192.168.0.0/16 --subnet=172.16.0.0/24
  1. Install the Tigera Calico operator and custom resource definitions.
  1. kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/tigera-operator.yaml

Due to the large size of the CRD bundle, kubectl apply might exceed request limits. Instead, use kubectl create or kubectl replace.

  1. Install Calico by creating the necessary custom resource. For more information on configuration options available in this manifest, see the installation reference.

Before creating this manifest, read its contents and make sure its settings are correct for your environment. For example, if you have replaced pod-network-cidr you must change it in this file as well.

  1. kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/custom-resources.yaml

Start your minikube cluster with one control plane node using the following command:

  1. minikube start --network-plugin=cni

Install Calico.

  1. kubectl apply -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/calico.yaml

Verify Calico installation

Verify Calico installation in your cluster using the following command:

  1. watch kubectl get pods -l k8s-app=calico-node -A

You should see a result similar to the below. Note that the namespace might be different, depending on the method you followed.

  1. NAMESPACE     NAME                READY   STATUS    RESTARTS   AGE
  2. kube-system   calico-node-mlqvs   1/1     Running   0          5m18s

Use ctrl+c to break out of watch.

Congratulations you now have a minikube cluster equipped with Calico
