Example 2 with ILocationMatch

use of alien4cloud.model.deployment.matching.ILocationMatch in project alien4cloud by alien4cloud.

the class LocationMatchingModifier method processLocationMatching.

private void processLocationMatching(Topology topology, FlowExecutionContext context) {
    // The configuration has already been loaded by a previous topology modifier.
    Optional<DeploymentMatchingConfiguration> configurationOptional = context.getConfiguration(DeploymentMatchingConfiguration.class, LocationMatchingModifier.class.getSimpleName());
    if (!configurationOptional.isPresent()) {
        return;
    }
    DeploymentMatchingConfiguration matchingConfiguration = configurationOptional.get();
    // If some of the locations defined does not exist anymore then just reset the deployment matching configuration
    Map<String, String> locationIds = matchingConfiguration.getLocationIds();
    if (MapUtils.isEmpty(locationIds)) {
        return;
    }
    // returns null if at least one of the expected location is missing.
    Map<String, Location> locations = getLocations(locationIds);
    if (locations == null) {

    context.getExecutionCache().put(FlowExecutionContext.DEPLOYMENT_LOCATIONS_MAP_CACHE_KEY, locations);
    // Now we must check that the selected locations are still valid choices for deployment
    // Somehow if the initial topology and none of the previous modifiers had changed then we could assume that the choice is still valid.
    // We had an approximation for that in the past that was not correct enough as we checked only initial topology and location. Actually inputs and
    // potential snapshot substitution merged through composition may also impact this. We know always re-process location matching here.
    // We have to fetch valid location matches anyway to know if the location is a potential valid match.
    List<ILocationMatch> locationMatches = locationMatchingService.match(topology, context.getEnvironmentContext().get().getEnvironment());
    context.getExecutionCache().put(FlowExecutionContext.LOCATION_MATCH_CACHE_KEY, locationMatches);

            return;
