Creating Instances

MySQL   |  PostgreSQL

Beta

This is a Beta release of Cloud SQL for PostgreSQL. This product might be changed in backward-incompatible ways and is not subject to any SLA or deprecation policy.

This page describes how to create a Google Cloud SQL for PostgreSQL instance.

For detailed information about all instance settings, see Instance Settings.

Creating an instance

Console

1. Go to the Cloud SQL Instances page in the Google Cloud Platform Console.

   Go to the Cloud SQL Instances page

2. Click Create instance.
3. Select PostgreSQL and click Next.
4. Enter an ID for the instance.
   You do not need to prepend the project ID onto the instance ID. This is done automatically where appropriate (for example, in the log files).
   Important: You should be aware that some resource identifiers (such as project IDs) might be retained beyond the life of your project. For this reason, avoid storing sensitive information in resource identifiers.
   ...see naming guidelines
5. Enter a password for the postgres user.
6. If needed, set any of the other optional instance settings.

   For information about the optional settings, see Instance Settings.

7. Click Create.
8. After the instance finishes initializing, select the instance to open it.

gcloud

For information about installing and getting started with the Cloud SDK, see Installing Cloud SDK. For information about the Cloud Shell, see Google Cloud Shell.

1. Create the instance:

   gcloud sql instances create [INSTANCE_NAME] --database-version=POSTGRES_9_6 \
          --cpu=[NUMBER_CPUS] --memory=[MEMORY_SIZE_IN_MBS]
   

   There are restrictions on the values for vCPUs and memory size:

   • vCPUs must be either 1 or an even number between 2 and 32.
   • Memory must be:
     • 0.9 to 6.5 GiB per vCPU
     • A multiple of 256 MiB
     • At least 3.75 GiB (3840 MiB)

   For example, the following string creates an instance with one vCPU and 3,840 MiB of memory:

    gcloud sql instances create myinstance --cpu=1 --memory=3840MiB \
           --database-version=POSTGRES_9_6
   

   You can also create a shared-core instance by using --tier db-f1-micro or --tier db-g1-small and dropping the --cpu and --memory parameters.

   For information about other available parameters, see the gcloud sql instances create command reference and Instance Settings.

2. Note the automatically assigned IP address.

   If you are not using the Cloud SQL Proxy, you will use this address as the host address that your applications or tools use to connect to the instance.

3. Set the password for the postgres user:

   gcloud sql users set-password postgres no-host --instance=[INSTANCE_NAME] \
          --password=[PASSWORD]
   

cURL

1. Create the instance:

   ACCESS_TOKEN="$(gcloud auth application-default print-access-token)"
   curl --header "Authorization: Bearer ${ACCESS_TOKEN}" \
        --header 'Content-Type: application/json' \
        --data '{"name":"[INSTANCE_NAME]", "region":"[REGION]",
                 "databaseVersion": "POSTGRES_9_6",
                 "settings": {"tier": "[TIER_STRING]",
                 "backupConfiguration": {"enabled":true}}}' \
        -X POST \
        https://www.googleapis.com/sql/v1beta4/projects/[PROJECT-ID]/instances
   

   TIER_STRING is a string that represents the number of CPUs and the amount of memory you want your new instance to have. The string has the following format: db-custom-[CPUS]-[MEMORY_MBS]. You can also create a shared-core instance by supplying db-f1-micro or db-g1-small for the tier parameter.

   This example creates an instance with backups enabled. For a complete list of parameters for this call, see the Instances:insert page. For information about instance settings, including valid values for region and machine type, see Instance Settings.

2. When the instance finishes initializing, update the password for the postgres user:

   curl --header "Authorization: Bearer ${ACCESS_TOKEN}" \
        --header 'Content-Type: application/json' \
        --data '{"name": "postgres", "host": "", "password": "[PASSWORD]"}' \
        -X PUT \
        'https://www.googleapis.com/sql/v1beta4/projects/[PROJECT-ID]/instances/[INSTANCE_NAME]/users?host=&name=postgres'
   

3. Retrieve the automatically assigned IPv4 address for the new instance:

   curl --header "Authorization: Bearer ${ACCESS_TOKEN}" \
        -X GET \
        https://www.googleapis.com/sql/v1beta4/projects/[PROJECT-ID]/instances/[INSTANCE_NAME]
   

   Look for the ipAddress field in the response.
