Install DCE 5.0 Enterprise offline¶

Ensure that you have read and understood the deployment requirements, deployment architecture, and preparation before installation.

Refer to the release notes to avoid known issues with the installed version and to check for new features.

Offline Installation Steps¶

Step 1: Download the Offline Package¶

Download the corresponding offline package based on your business environment.

Offline Image Package (Required)¶

The offline image package contains configuration files, image resources, and chart packages required for installing DCE 5.0 modules.

You can download the latest version from the Download Center.

After downloading, extract the offline package. Take the amd64 architecture offline package as an example

tar -xvf offline-v0.18.0-amd64.tar

ISO Operating System Image File (Required)¶

The ISO format operating system image file should be downloaded based on the different operating systems during the installation process.

The ISO operating system image file needs to be configured in clusterConfig.yaml, so download for your operating system.

osPackage Offline Packages (Required)¶

The osPackage offline package is a supplement to the Linux operating system offline software source provided by the open-source project Kubean. For example, openEuler 22.03 lacks the selinux-policy-35.5-15.oe2203.noarch.rpm.

Starting from version v0.5.0, the installer requires the osPackage offline package for the operating system and defines osPackagePath in clusterConfig.yaml.

Kubean provides osPackage offline packages for different operating systems, which can be found at https://github.com/kubean-io/kubean/releases.

Currently, the installer version requires the osPackage offline package version to match. Download the osPackage offline package based on the corresponding version:

For deploying DCE 5.0 on UOS V20 (1020a) operating system, refer to Deploying DCE 5.0 on UOS V20 (1020a).

Addon Offline Packages (Optional)¶

Addon offline packages contain Helm Chart offline packages for commonly used components. For the specific list, refer to the addon documentation.

Starting from installer version v0.5.0, support for importing addon offline packages is available. If you want to offline all the Helm charts in the addon package, you can download the latest version from the Download Center.

First, make sure to download the offline package in advance and define addonOfflinePackagePath in clusterConfig.yaml.
