Set Google Storage Bucket's default cache control

Question

Is there any way to set Bucket\'s default cache control (trying to override the public, max-age=3600 in bucket level every time creating a new object)

I know that this is quite an old question and you're after a default action (which I'm not sure exists), but the below worked for me on a recent PHP project after much frustration:

$object = $bucket->upload($tempFile, [
            'predefinedAcl' => "PUBLICREAD",
            'name' => $destination,
            'metadata' => [
                'cacheControl' => 'Cache-Control: private, max-age=0, no-transform',
            ]
        ]);

Same can be applied in node:

const storage = new Storage();

const bucket = storage.bucket(BUCKET_NAME);

const blob = bucket.file(FILE_NAME);

const uploadProgress = new Promise((resolve, reject) => {
    const blobStream = blob.createWriteStream();

    blobStream.on('error', err => {
      reject(err);

      throw new Error(err);
    });

    blobStream.on('finish', () => {
      resolve();
    });

    blobStream.end(file.buffer);
});

await uploadProgress;

if (isPublic) {
  await blob.makePublic();
}

blob.setMetadata({ cacheControl: 'public, max-age=31536000' });
