KubeSphere App Store

As an open-source and app-centric container platform, KubeSphere provides users with a Helm-based App Store for application lifecycle management on the back of OpenPitrix, an open-source web-based system to package, deploy and manage different types of apps. The KubeSphere App Store allows ISVs, developers, and users to upload, test, install, and release apps with just several clicks in a one-stop shop.

Internally, the KubeSphere App Store can serve as a place for different teams to share data, middleware, and office applications. Externally, it is conducive to setting industry standards of building and delivery. After you enable this feature, you can add more apps with app templates.

For more information, see App Store.

Enable the App Store Before Installation

Installing on Linux

When you implement multi-node installation of KubeSphere on Linux, you need to create a configuration file, which lists all KubeSphere components.

  1. In the tutorial of Installing KubeSphere on Linux, you create a default file config-sample.yaml. Modify the file by executing the following command:

    vi config-sample.yaml
    

    Note

    If you adopt All-in-One Installation, you do not need to create a config-sample.yaml file as you can create a cluster directly. Generally, the all-in-one mode is for users who are new to KubeSphere and look to get familiar with the system. If you want to enable the App Store in this mode (for example, for testing purposes), refer to the following section to see how the App Store can be installed after installation.
  2. In this file, navigate to openpitrix and change false to true for enabled. Save the file after you finish.

    openpitrix:
      store:
        enabled: true # Change "false" to "true".
    
  3. Create a cluster using the configuration file:

    ./kk create cluster -f config-sample.yaml
    

Installing on Kubernetes

As you install KubeSphere on Kubernetes, you can enable the KubeSphere App Store first in the cluster-configuration.yaml file.

  1. Download the file cluster-configuration.yaml and edit it.

    vi cluster-configuration.yaml
    
  2. In this local cluster-configuration.yaml file, navigate to openpitrix and enable the App Store by changing false to true for enabled. Save the file after you finish.

    openpitrix:
      store:
        enabled: true # Change "false" to "true".
    
  3. Execute the following commands to start installation:

    kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.0/kubesphere-installer.yaml
       
    kubectl apply -f cluster-configuration.yaml
    

Enable the App Store After Installation

  1. Log in to the console as admin. Click Platform in the upper-left corner and select Cluster Management.

  2. Click CRDs and enter clusterconfiguration in the search bar. Click the result to view its detail page.

    Info

    A Custom Resource Definition (CRD) allows users to create a new type of resources without adding another API server. They can use these resources like any other native Kubernetes objects.
  3. In Custom Resources, click on the right of ks-installer and select Edit YAML.

  4. In this YAML file, navigate to openpitrix and change false to true for enabled. After you finish, click OK in the lower-right corner to save the configuration.

    openpitrix:
      store:
        enabled: true # Change "false" to "true".
    
  5. You can use the web kubectl to check the installation process by executing the following command:

    kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
    

    Note

    You can find the web kubectl tool by clicking in the lower-right corner of the console.

Verify the Installation of the Component

After you log in to the console, if you can see App Store in the upper-left corner and apps in it, it means the installation is successful.

Note

  • You can even access the App Store without logging in to the console by visiting <Node IP Address>:30880/apps.
  • The OpenPitrix tab in KubeSphere 3.2.0 does not appear on the System Components page after the App Store is enabled.

Use the App Store in a Multi-cluster Architecture

In a multi-cluster architecture, you have one Host Cluster (H Cluster) managing all Member Clusters (M Clusters). Different from other components in KubeSphere, the App Store serves as a global application pool for all clusters, including H Cluster and M Clusters. You only need to enable the App Store on the H Cluster and you can use functions related to the App Store on M Clusters directly (no matter whether the App Store is enabled on M Clusters or not), such as App Templates and App Repositories.

However, if you only enable the App Store on M Clusters without enabling it on the H Cluster, you will not be able to use the App Store on any cluster in the multi-cluster architecture.
