    Overview

    AlloyDB for PostgreSQL is a fully managed PostgreSQL-compatible database service for your most demanding enterprise database workloads. AlloyDB combines the best of Google with one of the most popular open-source database engines, PostgreSQL, for superior performance, scale, and availability.

    In this lab, you perform several key fundamental tasks for creating and managing AlloyDB for PostgreSQL instances and databases.

    What you'll do

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

    • Create a cluster and instance.
    • Create tables and insert data in your database
    • Use the Google Cloud CLI with AlloyDB.
    • Delete an instance.

    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 are made available to you.

    This hands-on lab lets you do the lab activities in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials 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).
    Note: Use an Incognito (recommended) or private browser window to run this lab. This prevents conflicts between your personal account and the student account, which may cause extra charges incurred to your personal account.
    • Time to complete the lab—remember, once you start, you cannot pause a lab.
    Note: Use only the student account for this lab. If you use a different Google Cloud account, you may incur charges to that account.

    How to start your lab and sign in to the Google Cloud console

    1. Click the Start Lab button. If you need to pay for the lab, a dialog opens for you to select your payment method. On the left is the Lab Details pane with the following:

      • The Open Google Cloud console button
      • Time remaining
      • The temporary credentials that you must use for this lab
      • Other information, if needed, to step through this lab

    2. Click Open Google Cloud console (or right-click and select Open Link in Incognito Window if you are running the Chrome browser).

      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.

    3. If necessary, copy the Username below and paste it into the Sign in dialog.

      {{{user_0.username | "Username"}}}

      You can also find the Username in the Lab Details pane.

    4. Click Next.

    5. Copy the Password below and paste it into the Welcome dialog.

      {{{user_0.password | "Password"}}}

      You can also find the Password in the Lab Details pane.

    6. Click Next.

      Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.

    7. 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 Google Cloud console opens in this tab.

    Note: To access Google Cloud products and services, click the Navigation menu or type the service or product name in the Search field. Navigation menu icon and Search field

    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.

    1. Click Activate Cloud Shell Activate Cloud Shell icon at the top of the Google Cloud console.

    2. Click through the following windows:

      • Continue through the Cloud Shell information window.
      • Authorize Cloud Shell to use your credentials to make Google Cloud API calls.

    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:

    Your Cloud Platform project in this session is set to {{{project_0.project_id | "PROJECT_ID"}}}

    gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.

    1. (Optional) You can list the active account name with this command:
    gcloud auth list
    1. Click Authorize.

    Output:

    ACTIVE: * ACCOUNT: {{{user_0.username | "ACCOUNT"}}} To set the active account, run: $ gcloud config set account `ACCOUNT`
    1. (Optional) You can list the project ID with this command:
    gcloud config list project

    Output:

    [core] project = {{{project_0.project_id | "PROJECT_ID"}}} Note: For full documentation of gcloud, in Google Cloud, refer to the gcloud CLI overview guide.

    Task 1. Create a cluster and instance

    1. First create an AlloyDB cluster. On the Cloud Console Navigation menu (console_nav_small.png), click on View all products, scroll down to the Databases section and then select AlloyDB.

    2. Click Create cluster at the top of the page.

    3. In the Configure your cluster section, fill in the following fields. Please be certain to select the Region value listed below. Leave the others at their default value.

    Item Value
    Cluster ID lab-cluster
    Password Change3Me
    Region
    Network peering-network



    1. The private services access connection option was configured for this project when you started the lab. This step is required to allow access to the AlloyDB cluster.

    2. Under Configure your primary instance, set the instance ID as lab-instance.

    3. Select Multiple zones (Highly Available) in the Zonal availability section.

    4. Select 2 vCPU, 16 GB as your machine type.

    5. Scroll to the bottom of the page and click Create Cluster.

    Note: Cluster creation will take approximately 9 to 13 minutes.

    1. You're now on the Overview page for the new cluster you created. The bottom section contains details on your instance. Expand the Connectivity section. Please make note of the Private IP address in the instances section. Copy the Private IP address to a text file so that you can paste the value in a later step. Do not include the port number.

    2. Click Check my progress to verify the objective.

    Create a cluster and instance

    Task 2. Create tables and insert data in your database

    1. A VM named, alloydb-client, containing the PostgreSQL client was provisioned for you at the start of the lab.

    2. On the Navigation menu (Navigation menu icon), under Compute Engine click VM instances.

    3. For the instance named alloydb-client, in the Connect column, click SSH to open a terminal window.

    4. Set the following environment variable, replacing ALLOYDB_ADDRESS with the Private IP address of the AlloyDB instance.

    export ALLOYDB=ALLOYDB_ADDRESS
    1. Run the following command to store the Private IP address of the AlloyDB instance on the AlloyDB client VM so that it will persist throughout the lab.
    echo $ALLOYDB > alloydbip.txt
    1. Use the following command to launch the PostgreSQL (psql) client. You will be prompted to provide the postgres user's password (Change3Me) which you entered when you created the cluster.
    psql -h $ALLOYDB -U postgres
    1. You will be presented with the psql terminal prompt as shown below.
    psql (14.5 (Debian 14.5-1.pgdg110+1), server 14.4) SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off) Type "help" for help. postgres=>
    1. Input and run the following SQL command to create a new table named regions.
    CREATE TABLE regions ( region_id bigint NOT NULL, region_name varchar(25) ) ; ALTER TABLE regions ADD PRIMARY KEY (region_id);
    1. Next add several rows of data to the regions table. Input and run the following SQL command.
    INSERT INTO regions VALUES ( 1, 'Europe' ); INSERT INTO regions VALUES ( 2, 'Americas' ); INSERT INTO regions VALUES ( 3, 'Asia' ); INSERT INTO regions VALUES ( 4, 'Middle East and Africa' );
    1. Run the following simple query to verify that you inserted the records.
    SELECT region_id, region_name from regions;

    1. Type \q to exit the psql client.

    2. Another option to create tables and/or load data is by using a SQL file (.sql). A SQL file can contain DDL, DML or any supported SQL syntax. You will download and run a file containing DDL and DML, run that file, and then verify the load.

    3. Run the following command to download a file containing DDL and DML for three tables: countries, departments, and jobs.

    gsutil cp gs://cloud-training/OCBL403/hrm_load.sql hrm_load.sql
    1. Reconnect to the PostgreSQL (psql) client. You will be prompted to provide the postgres user's password (Change3Me).
    psql -h $ALLOYDB -U postgres
    1. Run the following command to process the sql file.
    \i hrm_load.sql
    1. Run the following command to see the tables that are loaded into your database.
    \dt List of relations Schema | Name | Type | Owner --------+-------------+-------+---------- public | countries | table | postgres public | departments | table | postgres public | jobs | table | postgres public | regions | table | postgres (4 rows)
    1. Run a spot check query to examine the data in one of the tables you just created and loaded.
    select job_title, max_salary from jobs order by max_salary desc;

    1. Type \q to exit the psql client.

    2. Type exit to close the terminal window.

    3. Click Check my progress to verify the objective.

    Create and load a table

    Task 3. Use the Google Cloud CLI with AlloyDB

    The Cloud Console is very useful, but in some use cases you want to manage AlloyDB databases using other methods. Google Cloud services can also be managed through the command line tool named gcloud. The easiest way to use the gcloud CLI is via the Cloud Shell but it can also be installed on a wide variety of operating systems.

    Create a cluster and instance with CLI

    1. Creating an AlloyDB cluster instance via gcloud is very simple. Click Activate Cloud Shell Activate Cloud Shell icon at the top of the Google Cloud console.

    2. In the Cloud Shell, create a new AlloyDB cluster using the command below.

    gcloud beta alloydb clusters create gcloud-lab-cluster \ --password=Change3Me \ --network=peering-network \ --region={{{primary_project.default_region|Default Region}}} \ --project={{{primary_project.project_id|Project ID}}}
    1. Once the cluster is created, run the following command to create the Primary instance.
    Note: The instance creation process will take 7 to 9 minutes. gcloud beta alloydb instances create gcloud-lab-instance\ --instance-type=PRIMARY \ --cpu-count=2 \ --region={{{primary_project.default_region|Default Region}}} \ --cluster=gcloud-lab-cluster \ --project={{{primary_project.project_id|Project ID}}}
    1. After the process completes, you can run the following command to list the AlloyDB clusters instances available in your project. The earlier instance you created, lab-cluster, and the one you just created, gcloud-lab-cluster, are returned in the listing.
    gcloud beta alloydb clusters list
    1. Click Check my progress to verify the objective.
    Create a cluster and instance with CLI

    Task 4. Deleting a cluster

    1. A very quick way to delete a cluster is by using the CLI. Run the following command. The force option deletes any subordinate instances as well. Another option to delete a cluster is to use the Cloud Console.
    Note: The deletion process will take 5 to 8 minutes. gcloud beta alloydb clusters delete gcloud-lab-cluster \ --force \ --region={{{primary_project.default_region|Default Region}}} \ --project={{{primary_project.project_id|Project ID}}}
    1. To confirm that gcloud-lab-cluster was deleted run the following command:

    If prompted Do you want to continue (Y/n)? press Y to continue.

    gcloud beta alloydb clusters list

    Congratulations!

    You now have a solid understanding of several key tasks when using an AlloyDB for PostgreSQL database.
