Mounting a Cloud Storage Buckets as a File System on CentOS 7 Compute Engine Instances

November 20, 2016November 20, 2016 Timmy Tin Leave a comment

Problem:

I need to mount a Google Cloud Storage Buckets to file system, and grant access to the web server.

Solution:

Use the Google Cloud Storage FUSE (gcsfuse) tool to mount a Cloud Storage bucket to your Compute Engine instance.

Steps:

Assumption:

I have a bucket named yctin-bucket
I want to mount this bucket to /cloud/yctin-bucket/
I was generated the Google Service Key, and stored into /src/gcloud_service_account.json

Mounting a bucket

# create the directory
mkdir -p /cloud/yctin-bucket/

# mount the bucket with 777 permission
gcsfuse --key-file=/src/gcloud_service_account.json -o allow_other --dir-mode 777 --file-mode 777  yctin-bucket  /cloud/yctin-bucket/

# create the directory

mkdir -p /cloud/yctin-bucket/

# mount the bucket with 777 permission

gcsfuse --key-file=/src/gcloud_service_account.json -o allow_other --dir-mode 777 --file-mode 777 yctin-bucket /cloud/yctin-bucket/

To unmount the bucket

umount /cloud/yctin-bucket/

1	umount /cloud/yctin-bucket/
