Golang NewRetryableBlobstore Examples

Example #1

File: blobstore_provider.go Project: pivotalservices/bosh-hub

func (p BlobstoreProvider) Get(provider string, options map[string]interface{}) (boshblob.Blobstore, error) {
	configDir, err := p.fs.TempDir("blobstore-s3-config")
	if err != nil {
		return nil, bosherr.WrapError(err, "Cerating tmp dir for blobstore config")
	}

	configPath := filepath.Join(configDir, "config.json")

	blobstore := boshblob.NewExternalBlobstore(
		provider,
		options,
		p.fs,
		p.runner,
		p.uuidGen,
		configPath,
	)

	blobstore = boshblob.NewSHA1VerifiableBlobstore(blobstore)

	blobstore = boshblob.NewRetryableBlobstore(blobstore, 3, p.logger)

	err = blobstore.Validate()
	if err != nil {
		return nil, bosherr.WrapError(err, "Validating blobstore")
