Examples with UpdateStackParam com.woorea.openstack.heat.model.UpdateStackParam used on opensource projects

Example 1 with UpdateStackParam

use of com.woorea.openstack.heat.model.UpdateStackParam in project so by onap.

the class MsoHeatUtilsWithUpdate method updateStack.

/**
 * Update a Stack in the specified cloud location and tenant. The Heat template and parameter map are passed in as
 * arguments, along with the cloud access credentials. It is expected that parameters have been validated and
 * contain at minimum the required parameters for the given template with no extra (undefined) parameters..
 *
 * The Stack name supplied by the caller must be unique in the scope of this tenant. However, it should also be
 * globally unique, as it will be the identifier for the resource going forward in Inventory. This latter is managed
 * by the higher levels invoking this function.
 *
 * The caller may choose to let this function poll Openstack for completion of the stack creation, or may handle
 * polling itself via separate calls to query the status. In either case, a StackInfo object will be returned
 * containing the current status. When polling is enabled, a status of CREATED is expected. When not polling, a
 * status of BUILDING is expected.
 *
 * An error will be thrown if the requested Stack already exists in the specified Tenant and Cloud.
 *
 * @param tenantId The Openstack ID of the tenant in which to create the Stack
 * @param cloudSiteId The cloud identifier (may be a region) in which to create the tenant.
 * @param stackName The name of the stack to update
 * @param heatTemplate The Heat template
 * @param stackInputs A map of key/value inputs
 * @param pollForCompletion Indicator that polling should be handled in Java vs. in the client
 * @param environment An optional yaml-format string to specify environmental parameters
 * @param files a Map<String, Object> for listing child template IDs
 * @param heatFiles a Map<String, Object> for listing get_file entries (fileName, fileBody)
 * @return A StackInfo object
 * @throws MsoException Thrown if the Openstack API call returns an exception.
