This page shows you how to use free trial credits to deploy a CockroachDB cluster on CockroachDB Standard (Preview) and use sample code to run your first queries.
Create a free trial cluster
- Create a CockroachDB Cloud account. If this is your first CockroachDB Cloud organization, it will be credited with $400 in free trial credits to get you started.
- On the Get Started page, click Create cluster.
- On the Select a plan page, select Standard.
- On the Cloud & Regions page, select a cloud provider (GCP or AWS).
- In the Regions section, select a region for the cluster. Refer to CockroachDB Cloud Regions for the regions where CockroachDB Standard clusters can be deployed. To create a multi-region cluster, click Add region and select additional regions.
- Click Next: Capacity.
On the Capacity page, keep the Provisioned capacity at the default value of 2 vCPUs.
Click Next: Finalize.
On the Finalize page, name your cluster. If an active free trial is listed in the right pane, you will not need to add a payment method, though you will need to do this by the end of the trial to maintain your organization's clusters.
Click Create cluster.
Your cluster will be created in a few seconds and the Create SQL user dialog will display.
Create a SQL user
The Create SQL user dialog allows you to create a new SQL user and password.
- Enter a username in the SQL user field or use the one provided by default.
- Click Generate & save password.
- Copy the generated password and save it in a secure location.
Click Next.
Currently, all new SQL users are created with admin privileges. For more information and to change the default settings, see Managing SQL users on a cluster.
Connect to the cluster
Select a language to connect a sample application to your cluster. To connect to your cluster directly from the command line, refer to Connect to a Standard Cluster.
Once you create a SQL user, the Connect to cluster dialog will show information about how to connect to your cluster.
- Select Java from the Select option/language dropdown.
Copy the
JDBC_DATABASE_URLenvironment variable command provided and save it in a secure location.Note:The connection string is pre-populated with your username, password, cluster name, and other details. Your password, in particular, will be provided only once. Save it in a secure place (Cockroach Labs recommends a password manager) to connect to your cluster in the future. If you forget your password, a Cluster Admin can reset it. Refer to: Managing SQL users on a cluster
Configure the connection environment variable
In a terminal, set the JDBC_DATABASE_URL environment variable to the JDBC connection string:
export JDBC_DATABASE_URL="<jdbc-connection-string>"
The code sample uses the connection string stored in the environment variable JDBC_DATABASE_URL to connect to your cluster.
In a terminal set the JDBC_DATABASE_URL environment variable to the JDBC connection string:
$env:JDBC_DATABASE_URL = "<jdbc-connection-string>"
The code sample uses the connection string stored in the environment variable JDBC_DATABASE_URL to connect to your cluster.
Run the Java sample code
Clone the
quickstart-code-samplesrepo:git clone https://github.com/cockroachdb/quickstart-code-samplesNavigate to the
javadirectory of the repo:cd quickstart-code-samples/javaThe code sample in this directory does the following:
- Connects to CockroachDB Cloud with the JDBC driver using the JDBC connection string set in the
JDBC_DATABASE_URLenvironment variable. - Creates a table.
- Inserts some data into the table.
- Reads the inserted data.
- Prints the data to the terminal.
- Connects to CockroachDB Cloud with the JDBC driver using the JDBC connection string set in the
Run the application using
gradlew:./gradlew runThe output should look like this:
> Task :app:run Hello world! BUILD SUCCESSFUL in 3s 2 actionable tasks: 2 executed
Once you create a SQL user, the Connect to cluster dialog will show information about how to connect to your cluster.
- Select General connection string from the Select option dropdown.
Open the General connection string section, then copy the connection string provided and save it in a secure location.
Note:The connection string is pre-populated with your username, password, cluster name, and other details. Your password, in particular, will be provided only once. Save it in a secure place (Cockroach Labs recommends a password manager) to connect to your cluster in the future. If you forget your password, a Cluster Admin can reset it. Refer to: Managing SQL users on a cluster
Configure the connection environment variable
In a terminal set the DATABASE_URL environment variable to the connection string:
export DATABASE_URL="<connection-string>"
The code sample uses the connection string stored in the environment variable DATABASE_URL to connect to your cluster.
In a terminal set the DATABASE_URL environment variable to the connection string:
$env:DATABASE_URL = "<connection-string>"
The code sample uses the connection string stored in the environment variable DATABASE_URL to connect to your cluster.
Run the Node.js sample code
Clone the
quickstart-code-samplesrepo:git clone https://github.com/cockroachdb/quickstart-code-samplesNavigate to the
nodedirectory of the repo:cd quickstart-code-samples/nodeThe code sample in this directory does the following:
- Connects to CockroachDB Cloud with the node-postgres driver using the connection string set in the
DATABASE_URLenvironment variable. - Creates a table.
- Inserts some data into the table.
- Reads the inserted data.
- Prints the data to the terminal.
- Connects to CockroachDB Cloud with the node-postgres driver using the connection string set in the
Install the app requirements:
$ npm installRun the app:
$ node app.jsThe output will look like this:
Hello world!
