Overview

Database Migration Service provides options for one-time and continuous jobs to migrate data to Cloud SQL using different connectivity options, including IP allowlists, VPC peering, and reverse SSH tunnels (see documentation on connectivity options at https://cloud.google.com/database-migration/docs/postgresql/configure-connectivity).

In this lab, you migrate a stand-alone PostgreSQL database (running on a virtual machine) to Cloud SQL for PostgreSQL using a continuous Database Migration Service job and VPC peering for connectivity.

Migrating a database via Database Migration Service requires some preparation of the source database, including creating a dedicated user with replication rights, adding the pglogical database extension to the source database and granting rights to the schemata and tables in the database to be migrated, as well as the postgres database, to that user.

After you create and run the migration job, you confirm that an initial copy of your database has been successfully migrated to your Cloud SQL for PostgreSQL instance. You also explore how continuous migration jobs apply data updates from your source database to your Cloud SQL instance. To conclude the migration job, you promote the Cloud SQL instance to be a stand-alone database for reading and writing data.

What you'll do

• Prepare the source database for migration.
• Create a profile for a source connection to a PostgreSQL instance (e.g., stand-alone PostgreSQL).
• Configure connectivity between the source and destination database instances using VPC peering.
• Configure firewall and database access rules to allow access to the source database for migration.
• Create, run, and verify a continuous migration job using Database Migration Service.
• Promote the destination instance (Cloud SQL for PostgreSQL) to be a stand-alone database for reading and writing data.

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).

Note: Use an Incognito or private browser window to run this lab. This prevents any 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: If you already have your own personal Google Cloud account or project, do not use it for this lab to avoid extra charges to your 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 pop-up opens for you to select your payment method. On the left is the Lab Details panel 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 panel.

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 panel.

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 view a menu with a list of Google Cloud products and services, click the Navigation menu at the top-left.

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 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:

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.

2. (Optional) You can list the active account name with this command:

gcloud auth list

3. Click Authorize.

Output:

ACTIVE: * ACCOUNT: {{{user_0.username | "ACCOUNT"}}} To set the active account, run: $ gcloud config set account `ACCOUNT`

4. (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.

Verify that the Database Migration API is enabled

1. In the Google Cloud console, enter Database Migration API in the top search bar. Click on the result for Database Migration API.

This page will either show status information or give you the option to enable the API.

2. If necessary, Enable the API.

Verify that the Service Networking API is enabled

The Service Networking API is required in order to be able to configure Cloud SQL to support VPC Peering and connections over a private ip-address.

1. In the Cloud console, enter Service Networking API in the top search bar. Click on the result for Service Networking API.

This page will either show status information or give you the option to enable the API.

2. If necessary, enable the API.

Task 1. Prepare the source database for migration

In this task you will add supporting features to the source database which are required in order for Database Migration Service to perform a migration. These are:

• Installing and configuring the pglogical database extension.
• Configuring the stand-alone PostgreSQL database to allow access from Cloud Shell and Cloud SQL.
• Adding the pglogicaldatabase extension to the postgres, orders and gmemegen_db databases on the stand-alone server.
• Creating a migration_admin user (with Replication permissions) for database migration and granting the required permissions to schemata and relations to that user.

Upgrade the database with the pglogical extension

In this step you will download and add the pglogical database extension to the orders and postgres databases on the postgresql-vm VM Instance.

1. In the Google Cloud console, on the Navigation menu (), click Compute Engine > VM instances.

2. In the entry for postgresql-vm, under Connect click SSH.

3. If prompted, click Authorize.

4. In the terminal in the new browser window, install the pglogical database extension:

sudo apt install postgresql-13-pglogical Note: pglogical is a logical replication system implemented entirely as a PostgreSQL extension. Fully integrated, it requires no triggers or external programs. This alternative to physical replication is a highly efficient method of replicating data using a publish/subscribe model for selective replication. Read more here: https://github.com/2ndQuadrant/pglogical

5. Download and apply some additions to the PostgreSQL configuration files (to enable pglogical extension) and restart the postgresql service:

sudo su - postgres -c "gsutil cp gs://cloud-training/gsp918/pg_hba_append.conf ." sudo su - postgres -c "gsutil cp gs://cloud-training/gsp918/postgresql_append.conf ." sudo su - postgres -c "cat pg_hba_append.conf >> /etc/postgresql/13/main/pg_hba.conf" sudo su - postgres -c "cat postgresql_append.conf >> /etc/postgresql/13/main/postgresql.conf" sudo systemctl restart postgresql@13-main

In pg_hba.conf these commands added a rule to allow access to all hosts:

#GSP918 - allow access to all hosts host all all 0.0.0.0/0 md5

In postgresql.conf, these commands set the minimal configuration for pglogical to configure it to listen on all addresses:

#GSP918 - added configuration for pglogical database extension wal_level = logical # minimal, replica, or logical max_worker_processes = 10 # one per database needed on provider node # one per node needed on subscriber node max_replication_slots = 10 # one per node needed on provider node max_wal_senders = 10 # one per node needed on provider node shared_preload_libraries = 'pglogical' max_wal_size = 1GB min_wal_size = 80MB listen_addresses = '*' # what IP address(es) to listen on, '*' is all

The above code snippets were appended to the relevant files and the PostgreSQL service restarted.

6. Launch the psql tool:

sudo su - postgres psql

7. Add the pglogical database extension to the postgres, orders and gmemegen_db databases.

\c postgres; CREATE EXTENSION pglogical; \c orders; CREATE EXTENSION pglogical; \c gmemegen_db; CREATE EXTENSION pglogical;

8. List the PostgreSQL databases on the server:

\l

Here you can see, besides the default postgresql databases, the orders and gmemegen_db databases provided for this lab. You will not use the gmemegen_db database in this lab, but will include it in the migration for use in a later lab.

List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges -------------+----------+----------+---------+---------+----------------------- gmemegen_db | postgres | UTF8 | C.UTF-8 | C.UTF-8 | orders | postgres | UTF8 | C.UTF-8 | C.UTF-8 | postgres | postgres | UTF8 | C.UTF-8 | C.UTF-8 | template0 | postgres | UTF8 | C.UTF-8 | C.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres template1 | postgres | UTF8 | C.UTF-8 | C.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres (5 rows)

Create the database migration user

In this step you will create a dedicated user for managing database migration.

1. In psql, enter the commands below to create a new user with the replication role:

CREATE USER migration_admin PASSWORD 'DMS_1s_cool!'; ALTER DATABASE orders OWNER TO migration_admin; ALTER ROLE migration_admin WITH REPLICATION;

Assign permissions to the migration user

In this step you will assign the necessary permissions to the migration_admin user to enable Database Migration Service to migrate your database.

1. In psql, grant permissions to the pglogical schema and tables for the postgres database.

\c postgres; GRANT USAGE ON SCHEMA pglogical TO migration_admin; GRANT ALL ON SCHEMA pglogical TO migration_admin; GRANT SELECT ON pglogical.tables TO migration_admin; GRANT SELECT ON pglogical.depend TO migration_admin; GRANT SELECT ON pglogical.local_node TO migration_admin; GRANT SELECT ON pglogical.local_sync_status TO migration_admin; GRANT SELECT ON pglogical.node TO migration_admin; GRANT SELECT ON pglogical.node_interface TO migration_admin; GRANT SELECT ON pglogical.queue TO migration_admin; GRANT SELECT ON pglogical.replication_set TO migration_admin; GRANT SELECT ON pglogical.replication_set_seq TO migration_admin; GRANT SELECT ON pglogical.replication_set_table TO migration_admin; GRANT SELECT ON pglogical.sequence_state TO migration_admin; GRANT SELECT ON pglogical.subscription TO migration_admin;

2. In psql, grant permissions to the pglogical schema and tables for the orders database.

\c orders; GRANT USAGE ON SCHEMA pglogical TO migration_admin; GRANT ALL ON SCHEMA pglogical TO migration_admin; GRANT SELECT ON pglogical.tables TO migration_admin; GRANT SELECT ON pglogical.depend TO migration_admin; GRANT SELECT ON pglogical.local_node TO migration_admin; GRANT SELECT ON pglogical.local_sync_status TO migration_admin; GRANT SELECT ON pglogical.node TO migration_admin; GRANT SELECT ON pglogical.node_interface TO migration_admin; GRANT SELECT ON pglogical.queue TO migration_admin; GRANT SELECT ON pglogical.replication_set TO migration_admin; GRANT SELECT ON pglogical.replication_set_seq TO migration_admin; GRANT SELECT ON pglogical.replication_set_table TO migration_admin; GRANT SELECT ON pglogical.sequence_state TO migration_admin; GRANT SELECT ON pglogical.subscription TO migration_admin;

3. In psql, grant permissions to the public schema and tables for the orders database.

GRANT USAGE ON SCHEMA public TO migration_admin; GRANT ALL ON SCHEMA public TO migration_admin; GRANT SELECT ON public.distribution_centers TO migration_admin; GRANT SELECT ON public.inventory_items TO migration_admin; GRANT SELECT ON public.order_items TO migration_admin; GRANT SELECT ON public.products TO migration_admin; GRANT SELECT ON public.users TO migration_admin;

4. In psql, grant permissions to the pglogical schema and tables for the gmemegen_db database.

\c gmemegen_db; GRANT USAGE ON SCHEMA pglogical TO migration_admin; GRANT ALL ON SCHEMA pglogical TO migration_admin; GRANT SELECT ON pglogical.tables TO migration_admin; GRANT SELECT ON pglogical.depend TO migration_admin; GRANT SELECT ON pglogical.local_node TO migration_admin; GRANT SELECT ON pglogical.local_sync_status TO migration_admin; GRANT SELECT ON pglogical.node TO migration_admin; GRANT SELECT ON pglogical.node_interface TO migration_admin; GRANT SELECT ON pglogical.queue TO migration_admin; GRANT SELECT ON pglogical.replication_set TO migration_admin; GRANT SELECT ON pglogical.replication_set_seq TO migration_admin; GRANT SELECT ON pglogical.replication_set_table TO migration_admin; GRANT SELECT ON pglogical.sequence_state TO migration_admin; GRANT SELECT ON pglogical.subscription TO migration_admin;

5. In psql, grant permissions to the public schema and tables for the gmemegen_db database.

GRANT USAGE ON SCHEMA public TO migration_admin; GRANT ALL ON SCHEMA public TO migration_admin; GRANT SELECT ON public.meme TO migration_admin;

The source databases are now prepared for migration. The permissions you have granted to the migration_admin user are all that is required for Database Migration Service to migrate the postgres, orders and gmemegen_db databases.

Make the migration_admin user the owner of the tables in the orders database, so that you can edit the source data later, when you test the migration.

6. In psql, run the following commands:

\c orders; \dt ALTER TABLE public.distribution_centers OWNER TO migration_admin; ALTER TABLE public.inventory_items OWNER TO migration_admin; ALTER TABLE public.order_items OWNER TO migration_admin; ALTER TABLE public.products OWNER TO migration_admin; ALTER TABLE public.users OWNER TO migration_admin; \dt List of relations Schema | Name | Type | Owner --------+----------------------+-------+------- public | distribution_centers | table | migration_admin public | inventory_items | table | migration_admin public | order_items | table | migration_admin public | products | table | migration_admin public | users | table | migration_admin (5 rows)

7. Exit psql and the postgres user session

\q exit

Click Check my progress to verify the objective. Prepare the PostgreSQL source instance for migration.

Task 2. Create a Database Migration Service connection profile for a stand-alone PostgreSQL database

In this task, you will create a connection profile for the PostgreSQL source instance.

Get the connectivity information for the PostgreSQL source instance

In this step, you identify the internal IP address of the source database instance that you will migrate to Cloud SQL.

1. In the Google Cloud Console, on the Navigation menu (), click Compute Engine > VM instances.

2. Locate the line with the instance called postgresql-vm.

3. Copy the value for Internal IP (e.g., 10.128.0.2).

Create a new connection profile for the PostgreSQL source instance

A connection profile stores information about the source database instance (e.g., stand-alone PosgreSQL) and is used by the Database Migration Service to migrate data from the source to your destination Cloud SQL database instance. After you create a connection profile, it can be reused across migration jobs.

In this step you will create a new connection profile for the PostgreSQL source instance.

1. In the Google Cloud Console, on the Navigation menu (), click Database Migration > Connection profiles.

2. Click + Create Profile.

3. For Database engine, select PostgreSQL.

4. For Connection profile name, enter postgres-vm.

5. For Hostname or IP address, enter the internal IP for the PostgreSQL source instance that you copied in the previous task (e.g., 10.128.0.2)

6. For Port, enter 5432.

7. For Username, enter migration_admin.

8. For Password, enter DMS_1s_cool! .

9. For Region select .

10. For all other values leave the defaults.

11. Click Create.

A new connection profile named postgres-vm will appear in the Connections profile list.

Click Check my progress to verify the objective. Create a connection profile for the PostgreSQL source instance.

Task 3. Create and start a continuous migration job

When you create a new migration job, you first define the source database instance using a previously created connection profile. Then you create a new destination database instance and configure connectivity between the source and destination instances.

In this task, you use the migration job interface to create a new Cloud SQL for PostgreSQL database instance and set it as the destination for the continuous migration job from the PostgreSQL source instance.

Create a new continuous migration job

In this step you will create a new continuous migration job.

1. In the Google Cloud Console, on the Navigation menu (), click Database Migration > Migration jobs.

2. Click + Create Migration Job.

3. For Migration job name, enter vm-to-cloudsql.

4. For Source database engine, select PostgreSQL.

5. For Destination region, select .

6. For Destination database engine, select Cloud SQL for PostgreSQL.

7. For Migration job type, select Continuous.

Leave the defaults for the other settings.

8. Click Save & Continue.

Define the source instance

In this step, you will define the source instance for the migration.

1. For Source connection profile, select postgres-vm.

Leave the defaults for the other settings.

2. Click Save & Continue.

Create the destination instance

In this step, you will create the destination instance for the migration.

1. For Destination Instance ID, enter postgresql-cloudsql.

2. For Password, enter supersecret!.

3. For Choose a Cloud SQL edition, select Enterprise edition.

4. For Database version, select Cloud SQL for PostgreSQL 13.

5. In Choose region and zone section, select Single zone and select as primary zone.

6. For Instance connectivity, select Private IP and Public IP.

7. Select Use an automatically allocated IP range.

Leave the defaults for the other settings.

7. Click Allocate & Connect.

Note: This step may take a few minutes. If asked to retry the request, click the Retry button to refresh the Service Networking API.

When this step is complete, an updated message notifies you that the instance will use the existing managed service connection.

You will need to edit the pg_hba.conf file on the VM instance to allow access to the IP range that is automatically generated in point 5 of the previous step. You will do this in a later step before testing the migration configuration at the end of this task.

Enter the additional information needed to create the destination instance on Cloud SQL.

8. For Machine shapes. check 1 vCPU, 3.75 GB

9. For Storage type, select SSD

10. For Storage capacity, select 10 GB

11. Click Create & Continue.

If prompted to confirm, click Create Destination & Continue. A message will state that your destination database instance is being created. Continue to the next step while you wait.

Define the connectivity method

In this step, you will define the connectivity method for the migration.

1. For Connectivity method, select VPC peering.

2. For VPC, select default.

VPC peering is configured by Database Migration Service using the information provided for the VPC network (the default network in this example).

When you see an updated message that the destination instance was created, proceed to the next step.

3. Click Configure & Continue.

Allow access to the posgresql-vm instance from automatically allocated IP range

In this step you will edit the pg_hba.conf PostgreSQL configuration file to allow the Database Migration Service to access the stand-alone PostgreSQL database.

1. Get the allocated IP address range. In the Google Cloud Console on the Navigation menu (), right-click VPC network > VPC network peering and open it in a new tab.

2. Click on the servicenetworking-googleapis-com entry.

3. In the Imported routes tab, select and copy the Destination IP range (e.g. 10.107.176.0/24).

4. In the Terminal session on the VM instance, edit the pg_hba.conf file as follows:

sudo nano /etc/postgresql/13/main/pg_hba.conf

5. On the last line of the file:

#GSP918 - allow access to all hosts host all all 0.0.0.0/0 md5

replace the "all IP addresses" range (0.0.0.0/0) with the range copied in point 3 above.

#GSP918 - allow access to all hosts host all all 10.107.176.0/24 md5 Note: The above step is not required to make the migration work, but it is good practice to make the source database more secure during the migration process, and also restricts access after the migration when the migrated database becomes the source of truth.

6. Save and exit the nano editor with Ctrl-O, Enter, Ctrl-X

7. Restart the PostgreSQL service to make the changes take effect. In the VM instance Terminal session:

sudo systemctl start postgresql@13-main

Test and start the continuous migration job

In this step, you will test and start the migration job.

1. In the Database Migration Service tab you open earlier, review the details of the migration job.

2. Click Test Job.

3. After a successful test, click Create & Start Job.

If prompted to confirm, click Create & Start.

Review the status of the continuous migration job

In this step, you will confirm that the continuous migration job is running.

1. In the Google Cloud Console, on the Navigation menu (), click Database Migration > Migration jobs.

2. Click the migration job vm-to-cloudsql to see the details page.

3. Review the migration job status.

   • If you have not started the job, the status will show as Not started. You can choose to start or delete the job.
   • After the job has started, the status will show as Starting and then transition to Running Full dump in progress to indicate that the initial database dump is in progress.
   • After the initial database dump has been completed, the status will transition to Running CDC in progress to indicate that continuous migration is active.

When the job status changes to Running CDC in progress, proceed to the next task.

Click Check my progress to verify the objective. Create, start, and review a continuous migration job.

Task 4. Confirm the data in Cloud SQL for PostgreSQL

Check the PostgreSQL databases in Cloud SQL

1. In the Google Cloud Console, on the Navigation menu (), click Databases > SQL.

2. Expand the instance ID called postgresql-cloudsql-master.
