Google cloud storage fuse

Overview

Google cloud storage fuse 내용 정리.

Basic

Cloud storage FUSE is an open source FUSE adapter that allows user to mound Cloud Storage buckets as file systems on Linux or macOS systems. It also provides a way for applications to upload and download Cloud Storage objects using standard file system semantics. Cloud Storage FUSE can be run anywhere with connectivity to Cloud Storage, including Google Compute Engine VMs or on-premises systems.

Mount

gcsfuse 를 이용하면 google cloud storage 를 파일시스템으로 mount를 시킬 수 있다. 이 때 중요한 것은 --implicit-dirs 옵션을 붙여주여야 디렉토리 구조가 보인다는 것이다.

Implicit directories

By default, there is no allowance for the implicit existence of directories. Since the usual file system operation like mkdir will do the right thing, if the user sets up a bucket's structure using only gcsfuse then user will not notice anything odd about this. If, however, user uses some other tool to set up objects in GCS(such as the storage browser in the Google Developer Console), user may notice that not all objects are visible unitil user creates leading directories for them.

For example, say that user uses some other tool to set up a single object named "foo/bar" in user's bucket, then mount the bucket with gcsfuse. The file system will initially appear empty, since there is no "foo/" object. However if the user subsequently run `mkdir foo`, user will now see a directory named "foo" containing a file named "bar".

gcsfuse supports a flag called `--implicit-dirs` that changes the behavior. When this flag is enabled, name
