This topic explains how to export and import cluster configurations in VMware Tanzu GemFire using the cluster configuration service.
The cluster configuration service exports and imports configurations created using gfsh
for an entire Tanzu GemFire cluster.
The cluster configuration service saves the cluster configuration as you create regions, disk-stores and other objects using gfsh
commands. You can export this configuration as well as any jar files that contain application files to a ZIP archive and then import this configuration to create a new cluster.
Issue the gfsh
export cluster-configuration
command to save the configuration data for your cluster in a ZIP archive. This ZIP file contains subdirectories for cluster-level configurations and a directory for each group specified in the cluster. The contents of these directories are described in Cluster Configuration Files and Troubleshooting.
To export a cluster configuration, run the gfsh
export cluster-configuration
command while connected to a Tanzu GemFire cluster. For example:
export cluster-configuration --zip-file-name=/home/username/configs/myConfig.zip
See export cluster-configuration.
Note: gfsh
only saves cluster configuration values for configurations specified using gfsh
. Configurations created by the management API are not saved with the cluster configurations.
Use the gfsh
import cluster-configuration
command to configure a new cluster based on a configuration exported from another system. You can import a cluster configuration only into a new cluster, or into a running cluster that has not yet been configured and contains no defined regions. That is, when:
or
After you have imported the configuration, any servers you start receive this cluster configuration.
To import a cluster configuration, start one or more locators and then run the gfsh
import cluster-configuration
command. For example:
import cluster-configuration --zip-file-name=/home/username/configs/myConfig.zip
