Exporting a Cluster Configuration
If a cluster was installed using the Installer or a Installer Stanza, you can use the export command
to generate a Stanza that captures the state of the cluster. You can then modify the Stanza to
perform incremental installs or upgrades.
This example uses the
export command to generate the
tt.yaml Stanza file. The command includes -n so that
certificates will not be
checked:./bin/mapr-installer-cli export -n --file /tmp/tt.yamlNOTE The
export command does not export the
config.ssh_password field. When using the exported YAML file, you need to
provide the password manually, pass it as an override, or specify a value contained in a
secured file, as described in Installing or Upgrading Core Using an Installer Stanza.For another example of using the export command, see MapR Stanzas (blog).
