Calico Cloud Free Tier quickstart guide

Get Calico Cloud running on a local Kind cluster, deploy a realistic microservices app, and explore your live Service Graph — all in a few minutes.

Before you begin

• Sign up for a Calico Cloud Free Tier account.
• Install Kind, Docker, and kubectl.

Step 1: Create a Kind cluster

1. Create a file called kind-config.yaml:

   kind: Cluster
   apiVersion: kind.x-k8s.io/v1alpha4
   nodes:
     - role: control-plane
     - role: worker
     - role: worker
   networking:
     disableDefaultCNI: true
     podSubnet: 192.168.0.0/16

   This tells Kind to create a three-node cluster without a default CNI, so you can install Calico in the next step.

2. Create the cluster:

   kind create cluster --name=calico-cluster --config=kind-config.yaml

3. Verify the nodes are up (they'll show NotReady until Calico is installed):

   kubectl get nodes

   Expected output

   NAME                           STATUS     ROLES           AGE   VERSION
   calico-cluster-control-plane   NotReady   control-plane   60s   v1.29.2
   calico-cluster-worker          NotReady   <none>          40s   v1.29.2
   calico-cluster-worker2         NotReady   <none>          40s   v1.29.2

Step 2: Install Calico

1. Install the Tigera operator and custom resource definitions:

   kubectl create -f $[manifestsUrl]/manifests/tigera-operator.yaml

2. Install Calico Cloud by creating the necessary custom resources:

   kubectl create -f $[manifestsUrl]/manifests/custom-resources.yaml

3. Wait for all components to become available:

   watch kubectl get tigerastatus

   After a few minutes, all components should show True in the AVAILABLE column.

   Expected output

   NAME                            AVAILABLE   PROGRESSING   DEGRADED   SINCE
   apiserver                       True        False         False      4m9s
   calico                          True        False         False      3m29s
   goldmane                        True        False         False      3m39s
   ippools                         True        False         False      6m4s
   whisker                         True        False         False      3m19s

Step 3: Connect to Calico Cloud Free Tier

1. In the Calico Cloud web console, click Connect a cluster.

2. Follow the prompts to name your cluster (for example, quickstart-cluster) and copy the generated kubectl command.

   What's happening in this command?

   This command creates three resources in your cluster:

   • A ManagementClusterConnection resource. This resource specifies the address of the Calico Cloud management cluster.
   • A Secret resource (tigera-managed-cluster-connection). This resource provides certificates for secure communication between your cluster and the Calico Cloud management cluster.
   • A Secret resource (tigera-voltron-linseed-certs-public). This resource provides certificates for secure communications for the specific components that Calico Cloud uses for log data and observability.

3. Run the kubectl command in your terminal.

4. Back in the console, click I applied the manifest. When the Managed Clusters page shows your cluster as Connected, move to the next step.

Step 4: Deploy the demo app

This step deploys Google's Online Boutique, a microservices demo with 12 services. Each service is deployed in its own namespace so that Service Graph displays a rich cross-namespace topology with realistic traffic patterns.

1. Deploy the application:

   kubectl apply -f https://docs.tigera.io/files/online-boutique-namespaced.yaml

   note

   The manifest includes a load generator that automatically drives traffic between all services. No manual traffic generation is needed.

2. Wait for all pods to reach Running status:

   watch "kubectl get pods -A | grep -v Running | grep -v Completed"

   This may take 2–3 minutes. When the only output is the header line, all pods are ready.

   What's in the demo app?

   The Online Boutique is a cloud-native e-commerce app made up of 12 microservices: adservice, cartservice, checkoutservice, currencyservice, emailservice, frontend, loadgenerator, paymentservice, productcatalogservice, recommendationservice, redis-cart, and shippingservice.

   Each service runs in its own namespace. A built-in load generator continuously sends requests through the frontend, creating realistic traffic across all services.

Step 5: Explore Service Graph

In the Calico Cloud web console, go to Service Graph. Within a minute or two you'll see every service and namespace mapped as a live node, with directional traffic flows between them.

Try clicking on a service — for example, cartservice. You'll see:

• Which services send traffic to it (such as checkoutservice and frontend)
• Which services it connects to (such as redis-cart)
• Flow logs with details on allowed and denied connections

Step 6: Clean up

1. Delete the Kind cluster:

   kind delete cluster --name=calico-cluster

2. In the Calico Cloud web console, go to Managed Clusters, click Actions > Disconnect, and then click I ran the commands. (Because you already deleted the cluster, you don't need to run the disconnect commands.)

3. Click Actions > Remove to fully remove the cluster from Calico Cloud.

Next steps

• Write a network policy to restrict traffic between services — for example, allow only cartservice to reach redis-cart.
• Set up alerts for unexpected traffic patterns.
• Explore the full feature set available on the Free Tier.
• Connect another cluster to Calico Cloud Free Tier.
