Step 2A: Deploy a VMware Tanzu™ Community Edition unmanaged cluster ¶
In this step of the tutorial, we will install an unmanaged TCE cluster .
By default, unmanaged clusters run locally via kind (default) or minikube with Tanzu components installed atop.
Spin up a TCE unmanaged cluster ¶
Create a cluster named for example
kubeapps-cluster
:tanzu unmanaged-cluster create kubeapps-cluster
Wait for the cluster to initialise:
📁 Created cluster directory 🧲 Resolving and checking Tanzu Kubernetes release (TKr) compatibility file projects.registry.vmware.com/tce/compatibility Compatibility file exists at ~/.config/tanzu/tkg/unmanaged/compatibility/projects.registry.vmware.com_tce_compatibility_v9 🔧 Resolving TKr projects.registry.vmware.com/tce/tkr:v1.22.7-2 TKr exists at ~/.config/tanzu/tkg/unmanaged/bom/projects.registry.vmware.com_tce_tkr_v1.22.7-2 Rendered Config: ~/.config/tanzu/tkg/unmanaged/kubeapps-cluster/config.yaml Bootstrap Logs: ~/.config/tanzu/tkg/unmanaged/kubeapps-cluster/bootstrap.log 🔧 Processing Tanzu Kubernetes Release 🎨 Selected base image projects.registry.vmware.com/tce/kind:v1.22.7 📦 Selected core package repository projects.registry.vmware.com/tce/repo-12:0.12.0 📦 Selected additional package repositories projects.registry.vmware.com/tce/main:0.12.0 📦 Selected kapp-controller image bundle projects.registry.vmware.com/tce/kapp-controller-multi-pkg:v0.30.1 🚀 Creating cluster kubeapps-cluster Cluster creation using kind! ❤️ Checkout this awesome project at https://kind.sigs.k8s.io Base image downloaded Cluster created To troubleshoot, use: kubectl ${COMMAND} --kubeconfig ~/.config/tanzu/tkg/unmanaged/kubeapps-cluster/kube.conf 📧 Installing kapp-controller kapp-controller status: Running 📧 Installing package repositories tkg-core-repository package repo status: Reconcile succeeded 🌐 Installing CNI calico.community.tanzu.vmware.com:3.22.1 ✅ Cluster created 🎮 kubectl context set to kubeapps-cluster View available packages: tanzu package available list View running pods: kubectl get po -A Delete this cluster: tanzu unmanaged delete kubeapps-cluster
The new unmanaged cluster is automatically added to your local kubeconfig. If you have kubectl installed locally, you can now use it to interact with the cluster.
Once the cluster is up and running, let’s check that the TCE catalog has been automatically added to it.
tanzu package repository list --all-namespaces
And the output should contain the most up-to-date TCE main catalog:
NAME REPOSITORY TAG STATUS DETAILS NAMESPACE projects.registry.vmware.com-tce-main-0.12.0 projects.registry.vmware.com/tce/main 0.12.0 Reconcile succeeded tanzu-package-repo-global tkg-core-repository projects.registry.vmware.com/tce/repo-12 0.12.0 Reconcile succeeded tkg-system
Authentication for an unmanaged cluster ¶
Unmanaged clusters are meant for development/testing mainly, and for this tutorial we will use the service account authentication.
Please remember that for any user-facing installation you should configure an OAuth2/OIDC provider to enable secure user authentication with Kubeapps and the cluster.
Credentials creation ¶
Let’s continue by creating a demo credential with which to access Kubeapps and Kubernetes.
Service account will be named kubeapps-operator
and will have cluster-admin
role.
kubectl create --namespace default serviceaccount kubeapps-operator
kubectl create clusterrolebinding kubeapps-operator --clusterrole=cluster-admin --serviceaccount=default:kubeapps-operator
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
name: kubeapps-operator-token
namespace: default
annotations:
kubernetes.io/service-account.name: kubeapps-operator
type: kubernetes.io/service-account-token
EOF
NOTE It’s not recommended to assign users the
cluster-admin
role for Kubeapps production usage.Please refer to the Access Control documentation to configure fine-grained access control for users.
Credentials retrieval ¶
In order to access Kubeapps, a token will be required. Given that we are using plain service account authentication, it is straightforward to obtain a token. Keep the obtained token for later steps of the tutorial.
On Linux/macOS ¶
kubectl get --namespace default secret kubeapps-operator-token -o go-template='{{.data.token | base64decode}}'
On Windows ¶
Open a Powershell terminal and run:
[Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($(kubectl get --namespace default secret kubeapps-operator-token -o jsonpath='{.data.token}')))
Continue the tutorial by preparing the Kubeapps deployment .
