What is Application Market?

Application Market allows you to add applications to the Cloud and then access the applications with one click. It extends the functionality of the Cloud. You can add default applications through the built-in installation package or add more applications through URLs.

Default Application

Applications installed through built-in installation packages.
  • ZStack Cloud currently provides the following application packages:
    • ZStack ZMigrate: A hybrid cloud migration service designed for ZStack Cloud, helping smoothly and efficiently migrate VM instances from various sources, including private and public clouds, to ZStack Cloud.
    • ZStack Zaku: A simple and user-friendly container management service. After the installation, you can conveniently use container features on ZStack Cloud.
    • ZStack Component Service Monitoring Suite: A monitoring suite helps visualize service process status of management and compute nodes, including UI service, monitoring collection service, zsha2 service, database service, host virtualization service, and host agent service.
    • Grafana: An open-source metric analysis and visualization suite that supports visualization of time series data from various time sources.
  • In addition to the application packages provided by ZStack Cloud, you can develop your own application packages, upload them to the specified path of ZStack Cloud, and conveniently install the applications through Application Market.

More Application

Additional applications that can be added to ZStack Cloud via URLs, allowing integrate more applications beyond default applications.


Install a Default Application

To install a default application, follow these steps:
  1. Download Application Image (Optional)
    • Generally, the system can automatically download the installation image when installing the application image. However, in the following scenarios, you need to manually download and upload application images in advance:
      • If you want to accelerate the application installation, we recommend that you prepare the image in advance.
      • If your cloud cannot access Internet, you need to prepare the image in advance.
      • If you install ZStack Zaku, you need to prepare the image in advance.
    • You can click here to download the images of applications provided by ZStack Cloud.
  2. Upload Application Image (Optional)

    After downloading the application image manually, you need upload it to the specified path with the following as guidance.

    • Rename the image to image.qcow2 and upload it to the following path on your management node and ImageStore (create the path if it does not exist)): /opt/zstack-marketplace-repo/{appName}/{Architecture}/{version}. For example, /opt/zstack-marketplace-repo/zstack_io_zaku/x86_64/3.1.0/image.qcow2
    • To ensure the correctness of the path and file name, we recommend that you contact the official technical support to execute this step.
  3. Install Application

    On the main menu of ZStack Cloud, choose Operational Management > Application Market > Default Application. On the Default Application page, locate an application and click Install Application. Then, the Install Application page appears.

    The application runs in VM instances. When installing application, the system creates corresponding VM instances simultaneously. Different applications may need different numbers of VM instances.

On the displayed page, set the following applications:
  • Name: Enter a name for the application.
  • CPU Architecture: Select a CPU architecture.
  • Version: Select the application version. The system acquires the corresponding application image according to the CPU architecture and the version you select.
  • CPU: Set the CPU cores of the VM instance.
  • Memory: Set the memory size of the VM instance. Unit: MB, GB, and TB.
  • Image Storage: Select an Image storage.
  • Root Volume: Set the root volume size of the VM instance. Unit: MB, GB, and TB.
  • Data Volume: Set the data volume size of the VM instance. Unit: MB, GB, and TB.
  • Network: Select a network for the VM instance.
  • Primary Storage: Optional. Manually specify a primary storage for the VM instance.
  • DevOps: Select whether to install DevOps components for the Zaku service to enable DevOps-related features.
