Example 1 with CacheWriter

use of com.google.cloud.tools.jib.cache.CacheWriter in project jib by google.

the class PullAndCacheBaseImageLayerStep method call.

/**
 * Depends on {@code pullAuthorizationFuture}.
 */
@Override
public CachedLayer call() throws IOException, RegistryException, LayerPropertyNotFoundException, ExecutionException, InterruptedException {
    try (Timer ignored = new Timer(buildConfiguration.getBuildLogger(), String.format(DESCRIPTION, layerDigest))) {
        RegistryClient registryClient = new RegistryClient(pullAuthorizationFuture.get(), buildConfiguration.getBaseImageRegistry(), buildConfiguration.getBaseImageRepository());
        // Checks if the layer already exists in the cache.
        CachedLayer cachedLayer = new CacheReader(cache).getLayer(layerDigest);
        if (cachedLayer != null) {
            return cachedLayer;
        }
        CacheWriter cacheWriter = new CacheWriter(cache);
        CountingOutputStream layerOutputStream = cacheWriter.getLayerOutputStream(layerDigest);
        registryClient.pullBlob(layerDigest, layerOutputStream);
        return cacheWriter.getCachedLayer(layerDigest, layerOutputStream);
    }
}

Example 2 with CacheWriter

use of com.google.cloud.tools.jib.cache.CacheWriter in project jib by google.

    String description = "Building " + layerType + " layer";
    return listeningExecutorService.submit(() -> {
