Create a Cloud Storage bucket
Run an Example Pipeline Remotely
Dataflow: Qwik Start - Python
In this lab you will set up your Python development environment, get the Cloud Dataflow SDK for Python, and run an example pipeline using the Cloud Console.
Setup and requirements
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.
To complete this lab, you need:
- Access to a standard internet browser (Chrome browser recommended).
- Time to complete the lab---remember, once you start, you cannot pause a lab.
How to start your lab and sign in to the Google Cloud Console
Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is the Lab Details panel with the following:
- The Open Google Console button
- Time remaining
- The temporary credentials that you must use for this lab
- Other information, if needed, to step through this lab
Click Open Google Console. The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Arrange the tabs in separate windows, side-by-side.
Note: If you see the Choose an account dialog, click Use Another Account.
If necessary, copy the Username from the Lab Details panel and paste it into the Sign in dialog. Click Next.
Copy the Password from the Lab Details panel and paste it into the Welcome dialog. Click Next.
Important: You must use the credentials from the left panel. Do not use your Google Cloud Skills Boost credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.
Click through the subsequent pages:
- Accept the terms and conditions.
- Do not add recovery options or two-factor authentication (because this is a temporary account).
- Do not sign up for free trials.
After a few moments, the Cloud Console opens in this tab.
Activate Cloud Shell
Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.
- Click Activate Cloud Shell at the top of the Google Cloud console.
When you are connected, you are already authenticated, and the project is set to your PROJECT_ID. The output contains a line that declares the PROJECT_ID for this session:
gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.
- (Optional) You can list the active account name with this command:
Your output should now look like this:
- (Optional) You can list the project ID with this command:
gcloud, in Google Cloud, refer to the gcloud CLI overview guide.
Set the region
- In Cloud Shell, run the following command to set the project region for this lab:
Ensure that the Dataflow API is successfully enabled
To ensure access to the necessary API, restart the connection to the Dataflow API.
In the Cloud Console, enter "Dataflow API" in the top search bar. Click on the result for Dataflow API.
Click Disable API.
If asked to confirm, click Disable.
- Click Enable.
When the API has been enabled again, the page will show the option to disable.
Task 1. Create a Cloud Storage bucket
- On the Navigation menu (), click Cloud Storage > Buckets.
- Click Create bucket.
- In the Create bucket dialog, specify the following attributes:
Name: To ensure a unique bucket name, use the following name:
-bucket. Note that this name does not include sensitive information in the bucket name, as the bucket namespace is global and publicly visible.
- Location type: Multi-region
- A location where bucket data will be stored.
If Prompted Public access will be prevented, click Confirm.
Test completed task
Click Check my progress to verify your performed task. If you have completed the task successfully you will be granted an assessment score.
Task 2. Install pip and the Cloud Dataflow SDK
- The latest Cloud Dataflow SDK for Python requires a Python version >= 3.7.
To ensure you are running the process with the correct version, run the
Python3.9 Docker Image:
This command pulls a Docker container with the latest stable version of Python 3.9 and then opens up a command shell for you to run the following commands inside your container.
- After the container is running, install the latest version of the Apache Beam for Python by running the following command from a virtual environment:
You will see some warnings returned that are related to dependencies. It is safe to ignore them for this lab.
- Run the
wordcount.pyexample locally by running the following command:
You may see a message similar to the following:
This message can be ignored.
- You can now list the files that are on your local cloud environment to get the name of the
- Copy the name of the
Your results show each word in the file and how many times it appears.
Task 3. Run an example pipeline remotely
- Set the BUCKET environment variable to the bucket you created earlier:
- Now you'll run the
In your output, wait until you see the message:
Then continue with the lab.
Task 4. Check that your job succeeded
- Open the Navigation menu and click Dataflow from the list of services.
You should see your wordcount job with a status of Running at first.
- Click on the name to watch the process. When all the boxes are checked off, you can continue watching the logs in Cloud Shell.
The process is complete when the status is Succeeded.
Test completed task
Click Check my progress to verify your performed task. If you have completed the task successfully you will be granted with an assessment score.
Click Navigation menu > Cloud Storage in the Cloud Console.
Click on the name of your bucket. In your bucket, you should see the results and staging directories.
Click on the results folder and you should see the output files that your job created:
Click on a file to see the word counts it contains.
Task 5. Test your understanding
