How to mount a Google Cloud Bucket in Linux using gcsfuse



Mounting a Google Cloud Storage bucket into CentOS/Debian


So here are the steps;

Create a GCP Cloud Storage bucket

Add a service account to which has access to that bucket

Install GCSFuse (The software that actually does the job) on the server

Prepare to mount (like we were doing bungee jumping up-to this point)

[Optional] Configure HTTP proxy settings

Mount the bucket


key.json create

enable api

from the top area click the Create Service Account button.

Add a unique name, and press Create

In the grant service account access step, select Cloud Storage > Storage Object Admin

Goto Console-> IAM -> service account -> create Service account -> (... Actions) -> Manage Key -> create json file ->

upload this key.json file to linux instance

gcsfuse --key-file /home/khan/stl-td2e879f.json --foreground /bucketdata



Mount in a Ubuntu instance


** Install gcsfuse

Enter the following commands one by one

sudo apt-get update

sudo apt-get install curl -y

export GCSFUSE_REPO=gcsfuse-`lsb_release -c -s`

echo "deb $GCSFUSE_REPO main" | sudo tee /etc/apt/sources.list.d/gcsfuse.list

curl | sudo apt-key add -

sudo apt-get update

sudo apt-get install gcsfuse

As of now, you should have gcsfuse installed and ready for action. But we will need google-cloud-sdk for authenticating to the Google Storage

** Install Google Cloud SDK

export CLOUD_SDK_REPO="cloud-sdk-$(lsb_release -c -s)"

echo "deb $CLOUD_SDK_REPO main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list

curl | sudo apt-key add -

sudo apt-get update && sudo apt-get install google-cloud-sdk

Authenticate with Google Cloud Storage

Switch to the user you will be mounting your bucket with. And issue the following command

gcloud auth application-default login

This will present you with a URL. Copy that URL and paste it in your browser, login with your Google account. You should see a token on your browser window. Copy it and paste it in the Terminal prompt asking for the verification code.

Once you give the token, you should be authenticated and you can now mount your Bucket.

Mount the bucket

Again, switch to the user you want to mount the bucket as. This is important because you cannot change the ownership of the mount. If you mount it with root user, then the mount can only be used by the root user.

mkdir /mnt/google-cloud-bucket

gcsfuse your_bucket_name /mnt/google-cloud-bucket

That’s it, you should have your bucket mounted on your system. You can verify the mount using the df -h command
