kubectl apply


The installation of Clusterpedia is divided into several parts:

If you use existing storage component (MySQL or PostgreSQL), directly skip the step of installing the storage component.

Pull clusterpedia project:

git clone https://github.com/clusterpedia-io/clusterpedia.git
cd clusterpedia
git checkout v0.7.0

Install storage component

Clusterpedia installation provides two storage components (MySQL 8.0 and PostgreSQL 12) to choose.

If you use existing storage components (MySQL or PostgreSQL), directly skip this step

Go to the installation directory of the selected storage component

cd ./deploy/internalstorage/postgres

Go to the installation directory of the selected storage component

cd ./deploy/internalstorage/mysql

The storage component uses the Local PV method to store data, and you shall specify the node where the Local PV is located during deployment

You can choose to provide your own PV

export STORAGE_NODE_NAME=<nodename>
sed "s|__NODE_NAME__|$STORAGE_NODE_NAME|g" `grep __NODE_NAME__ -rl ./templates` > clusterpedia_internalstorage_pv.yaml

Deploy storage component

kubectl apply -f .

# Go back to Clusterpedia root directory
cd ../../../

Install Clusterpedia

Once the storage component are successfully deployed, you can install the Clusterpedia.

If you uses existing storage component, refer to Configure Storage Layer to set the storage component into Default Storage Layer

Run the following cmd in the clusterpedia root directory

# Deploy Clusterpedia CRD and components
kubectl apply -f ./deploy

Final check

Check if the component Pods are running properly

kubectl -n clusterpedia-system get pods

Create Cluster Auto Import Policy —— ClusterImportPolicy

After 0.4.0, Clusterpedia provides a more friendly way to interface to multi-cloud platforms.

Users can create ClusterImportPolicy to automatically discover managed clusters in the multi-cloud platform and automatically synchronize them as PediaCluster, so you don’t need to maintain PediaCluster manually based on the managed clusters.

We maintain PediaCluster for each multi-cloud platform in the Clusterpedia repository. ClusterImportPolicy` for each multi-cloud platform. People also submit ClusterImportPolicy to Clusterpedia for interfacing to other multi-cloud platforms.

After installing Clusterpedia, you can create the appropriate ClusterImportPolicy, or create a new ClusterImportPolicy according to your needs (multi-cloud platform).

For details, please refer to Interfacing to Multi-Cloud Platforms

kubectl get clusterimportpolicy


Clean up ClusterImportPolicy

If you have deployed ClusterImportPolicy then you need to clean up the ClusterImportPolicy resources first.

kubectl get clusterimportpolicy

Clean up PediaCluster

Before uninstalling Clusterpedia, you need to check if PediaCluster resources still exist in your environment, and clean up those resources.

kubectl get pediacluster

Uninstall Clusterpedia

After the PediaCluster resource cleanup is complete, uninstall the Clusterpedia components.

kubectl delete -f ./deploy/clusterpedia_apiserver_apiservice.yaml
kubectl delete -f ./deploy/clusterpedia_apiserver_deployment.yaml
kubectl delete -f ./deploy/clusterpedia_clustersynchro_manager_deployment.yaml
kubectl delete -f ./deploy/clusterpedia_apiserver_rbac.yaml
kubectl delete -f ./deploy/cluster.clusterpedia.io_pediaclusers.yaml

Uninstall Storage Component

Remove related resources depending on the type of storage component selected.

kubectl delete -f ./deploy/internalstorage/<storage type>

remove Local PV and clean up data

After the storage component is uninstalled, the Local PV and corresponding data will still be left in the node and we need to clean it manually.

View the mounted nodes via Local PV resource details.

kubectl get pv clusterpedia-internalstorage-<storage type>

Once you know the node where the data is stored, you can delete the Local PV.

kubectl delete pv clusterpedia-internalstorage-<storage type>

Log in to the node where the data is located and clean up the data.

# In the node where the legacy data is located
rm -rf /var/local/clusterpedia/internalstorage/<storage type>
