Installation and Deployment

Installation and Deployment Overview

ZStack Cloud Foundation (ZCF) supports the following installation and initialization methods:

Install by using the ZCF Installer (Installer).
Install from the ZStack Cloud Application Market.

Before installing ZCF, prepare an available ZStack Cloud platform. To manage storage, container, or network resources in ZCF, prepare infrastructure components such as ZStack ZStone and ZStack Zaku, and extension capabilities such as ZStack ZNS (ZCF Network Service) as planned.

When setting up a ZCF environment for the first time, complete the installation and deployment in the following order:

Stage	Description
Prepare ZStack Cloud	Before installing ZCF, prepare an available ZStack Cloud platform.
Prepare infrastructure components (optional)	To manage storage or container resources in ZCF, prepare infrastructure components such as ZStack ZStone and ZStack Zaku as planned.
Install ZCF	You can install ZCF by using one of the following methods: Install by using the Installer. Install from the ZStack Cloud Application Market. After installation, the Unified Portal and ZCF Observability capabilities become available.
Perform post-deployment checks	Verify that ZStack Cloud UI, Global Management, ZCF Cloud Federation, Dashboards & Reports, and Operations are accessible.
Connect infrastructure components (optional)	After ZCF is deployed, use ZCF Cloud Federation to connect product environments such as ZStack Cloud, ZStack ZStone, and ZStack Zaku, providing the foundation for cross-product access, resource collection, and observability analysis.
Install extension components (optional)	After access to the ZStack Cloud UI is verified, install extension components from the ZStack Cloud Application Market, such as ZStack Network Service (ZNS).

This section describes the basic workflow for pre-deployment preparation, ZCF installation, infrastructure component connection, extension capability installation, and post-deployment checks. For production deployments, verify node specifications, network planning, component scope, domain names, VIP, and security policies according to the plan.

Prepare ZStack Cloud

Before installing ZCF, make sure that a usable ZStack Cloud platform has been installed and that the ZStack Cloud management node is accessible. ZStack Cloud provides the base environment for ZCF installation, resource connection, and subsequent management.

ZStack Cloud plays the following roles in different installation methods:

When ZCF is installed by using the Installer, the Installer connects to the ZStack Cloud management node and completes ZStack Cloud access during installation.
When ZCF is installed from the ZStack Cloud Application Market, administrators start ZCF installation from the Application Market in the ZStack Cloud UI and complete installation parameter configuration as prompted.

For ZStack Cloud installation, refer to ZStack Cloud Documentation.

Prepare Infrastructure Components (Optional)

To view and manage storage, container, and other resources in ZCF, prepare infrastructure components such as ZStack ZStone and ZStack Zaku as planned. After these infrastructure components are prepared and ZCF is deployed, you can connect them through ZCF Cloud Federation.

After the infrastructure components are deployed, verify that their management pages or services are accessible, and record the access addresses and account information required for later ZCF Cloud Federation connection.

Install ZCF

Deployment Methods

ZCF supports the following installation methods:

Install by using the Installer: See Install by Using the Installer.
Install from the ZStack Cloud Application Market: See Install from the ZStack Cloud Application Market.

Deployment Modes

ZCF supports single-node deployment and HA deployment. Before installation, select a deployment mode based on the environment purpose, availability requirements, and resource plan.

Deployment Mode	Description
Single-node Deployment	Runs ZCF services on one ZCF instance. This mode is suitable for test, demo, or planned single-node environments.
HA Deployment	Runs ZCF services on three ZCF instances to provide high availability. This mode is suitable for production or HA environments.

Install by Using the Installer

Installing ZCF by using the Installer applies to scenarios where ZCF is deployed from a standalone Installer node. In the Installer UI, you can select the deployment mode, enter node information, confirm the package source, select components, connect ZStack Cloud, configure the License Server, run preflight checks, and execute the deployment.

This section describes the detailed steps for installing ZCF by using the Installer.

Prepare the Installation Environment

Before installing ZCF by using the Installer, prepare nodes, deployment information, network, and installation media.

Node Description

The installation and deployment process involves the following node concepts:

Node	Description
Installer Node	The server that runs the ZCF Installer package. It starts the Installer UI and serves as the deployment operation page. In `http://<Installer Node IP>:8069`, the IP address is the Installer node IP.
ZCF Service Node	The server where ZCF services are installed and run. Prepare one ZCF service node for single-node deployment, and three ZCF service nodes for HA deployment.
ZStack Cloud Management Node	The management node of ZStack Cloud. The Installer uses it to complete ZStack Cloud access during deployment.

In single-node deployment, the Installer node can be the same server as the ZCF service node. In HA deployment, one ZCF service node can also run the Installer. Verify the node relationship before deployment.

Deployment Information Confirmation

Before deployment, prepare and verify the following information:

Item	Information to Confirm
CPU Architecture	Confirm the CPU architecture of the Installer node and ZCF service nodes, and prepare the matching installation package.
ZCF Service Nodes	Prepare one server for single-node deployment or three servers for HA deployment, and confirm node IP addresses or FQDNs.
SSH Username and Port	The Installer uses this information to log in to ZCF service nodes and run deployment tasks. The user must have permission to install and manage services.
Local Package Directory	Stores ZCF installation packages. The Installer must be able to read this directory.
Deployment Components	Confirm the components to install, such as ZCF control plane, SSO, and ZMetis (ZCF Observability).
ZCF Service VIP	VIP address used to access ZCF services.
Domain Name or Access Point	If a domain name or unified access point is required, confirm DNS resolution and access policies in advance.
ZStack Cloud Management Node	Verify that a ZStack Cloud platform has been installed and is accessible. Record the IP address, access point, and connection information of the ZStack Cloud management node.
Administrator Password	Set the ZCF administrator password according to your password policy.
