Overview

In this lab, you use gcloud storage to create a bucket and perform operations on objects. gcloud storage is part of the Google Cloud CLI that lets you access Cloud Storage from the command line, providing unified syntax and high-performance parallel transfers. The gcloud storage tool has subcommands such as buckets create and cp to perform operations. Each command has a set of options that you can use to customize settings further.

What you'll learn

In this lab, you learn how to perform the following tasks:

• Create a bucket
• Copy files from a local folder to a bucket
• Synchronize the contents of the local folder with the contents of the bucket
• Change access control permissions on objects

Setup and requirements

• Labs are timed and cannot be paused. The timer starts when you click Start Lab.
• The included cloud terminal is preconfigured with the gcloud SDK.
• Use the terminal to execute commands and then click Check my progress to verify your work.

Get the sample code and set variables

1. In the cloud terminal session, execute the following command to download sample data from the pre-provisioned assets bucket:

2. Set some environment variables:

Task 1. Create a bucket

• Run the following command to create a bucket with multi-regional storage class:

The gcloud storage buckets create command is used to create a new Google Cloud Storage bucket. The --default-storage-class flag allows you to specify the storage class for the bucket, and the multi_regional storage class is designed for data that needs to be available in multiple regions (ideal for high availability and low-latency access).

Click Check my progress to verify the objective.

Task 2. Upload objects to your bucket

• Run the following to copy the endpointslambda object to your bucket:

The gcloud storage cp -r command is used to copy files or directories to a Google Cloud Storage bucket.

In gcloud storage, multi-threaded and multi-processing parallel transfers are enabled automatically for high performance. The -r option allows recursion through directories.

Click Check my progress to verify the objective.

Task 3. List objects

• To list objects in your bucket, execute the following command:

This command lists all objects (files and directories) inside a specific bucket in Google Cloud Storage, including any nested objects.

Task 4. Sync changes with bucket

1. Use the following commands to rename and delete some files:

2. Now synchronize the local changes with the bucket:

In this command, the --delete-unmatched-destination-objects flag deletes files from the target if they're missing in the source (in this case, it deletes app.yaml from the bucket). The -r option runs the command recursively across subdirectories.

3. To verify that the bucket is now in sync with your local changes, list the files in the bucket again:

Click Check my progress to verify the objective.

Task 5. Make objects public

1. To allow public access to all files under the endpointslambda folder in your bucket, execute the following command:

The above command is used to grant public read permissions to Cloud Storage buckets and objects using IAM policy bindings. This makes all objects in the bucket publicly readable.

The --member=allUsers flag grants access to any user on the internet, while --role=roles/storage.objectViewer grants read permissions for objects in the bucket.

2. To confirm files are viewable by the public, open the following link in a new incognito or private browser window, replacing <your-bucket-name> with the full name of your bucket, not the environment variable:

This URL uses the Cloud Storage API link to view the object without authentication. Learn more about accessing public data from the Accessing public data documentation.

Task 6. Copy with different storage class

• Next, copy a file with Nearline storage class instead of the bucket's default Multi-regional storage class:

The gcloud storage cp command is used to copy files from one location to another, either within Cloud Storage or from a local file system to Cloud Storage and --storage-class flag specifies the storage class for the file being uploaded.

Click Check my progress to verify the objective.

Task 7. Check storage classes

1. Run the following to check the storage classes and view other detailed information about the objects in your bucket:

2. Press the SPACE key to continue viewing the rest of the command's output.

The output shows that the ghcn_on_bq.ipynb object has NEARLINE storage class while the other objects have MULTI_REGIONAL storage class.

Output:

3. Press CTRL+C to return to the command line.

Congratulations

You have now learned how to perform operations on Cloud Storage buckets and objects!
