Create a Cloud spanner instance

Question

I want to set up a relational database that offers transactional consistency at global scale, that is also having high availability. I found Cloud spanner as the perfect match for my requirements. How to create a cloud spanner instance on google cloud?

Answer 1

You can create an instance with the gcloud command-line tool or with the Google Cloud Platform Console.

Use the gcloud spanner instances create command:

gcloud spanner instances create [INSTANCE-ID] --config=[INSTANCE-CONFIG] \
    --description="[INSTANCE-NAME]" --nodes=[NODE-COUNT]

Provide the following values:

• [INSTANCE-ID]: A permanent identifier that is unique within your Google Cloud Platform project. You cannot change the instance ID later.

• [INSTANCE-CONFIG]: The instance configuration, which defines the geographic location of the instance's nodes and affects how data is replicated.

• [INSTANCE-NAME]: The name to display for the instance in the GCP Console. The instance name must be unique within your Google Cloud Platform project.

• [NODE-COUNT]: The number of nodes for the instance. The number of nodes determines the amount of serving and storage resources that are available to databases in the instance.

For example:

gcloud spanner instances create test-instance --config=regional-us-central1 \
    --description="Test Instance" --nodes=1

You should see a message similar to the following example:

Creating instance...done.
