Set up Docker-Based Couchbase Cluster<\/h2>\n

Couchbase is an open-source NoSQL database that can handle many users at once, making it ideal for interactive applications and Big Data. It can be used as a document database, key-value store, or distributed cache.<\/p>\n

Starting with version 4.x, Couchbase offers Multi-Dimensional Scaling, allowing it to grow both vertically and horizontally. To fully use this feature, you’ll need a flexible hosting platform, like our PaaS.<\/p>\n

To improve availability and failover, you can combine multiple Couchbase instances<\/a> into a reliable cluster.<\/p>\n

Below are step-by-step instructions on setting up a scalable Couchbase DB cluster on the platform.<\/p>\n

Environment Creation<\/h2>\n

To make deploying the database easy, we’ll use Docker containers on the platform with a pre-made Docker template that includes the Couchbase image.<\/p>\n

Step 1.<\/strong> Click the “New Environment”<\/strong> button at the top of the platform dashboard. In the wizard that opens, switch to the Custom tab and click “Select Image”<\/strong> in the middle section.<\/p>\n

\"Select<\/a><\/p>\n

Step 2.<\/strong> Use the search function to find and select the “couchbase\/server”<\/strong> image. Click “Next”<\/strong> to continue.<\/p>\n

\"Couchbase<\/a><\/p>\n

Step 3.<\/strong> In the Horizontal Scaling<\/a> section, use the +\/- buttons to set the number of servers (we’ll use 3 as an example).<\/a><\/p>\n

Set resource limits for each server using the cloudlet sliders in the Vertical Scaling per node section. Choose the environment region,<\/a> name it (e.g., couchbase), and click “Create.”<\/p>\n

\"Custom<\/a><\/p>\n

Step 4.<\/strong> After a few minutes, your environment will appear on the dashboard.<\/p>\n

\"Created<\/a><\/p>\n

To check if everything went well, click the “Show Logs”<\/strong> button in the pop-up message.<\/p>\n

\"Log<\/a><\/p>\n

The logs should show no errors and indicate that the web UI is accessible at port 8091.<\/p>\n

Launch Couchbase<\/h2>\n

To access the Couchbase web interface and start managing it, you can either attach a public IP to your environment (a paid option) and open it at port 8091, or add a corresponding endpoint for free. We’ll cover the free option:<\/p>\n

Step 1.<\/strong> Click the “Settings”<\/strong> (wrench icon) next to your environment, go to the “Endpoints”<\/strong> menu, and click the “Add”<\/strong> button.<\/p>\n

\"Endpoint\"<\/a><\/p>\n

Step 2.<\/strong> In the form that appears, fill in the following details:<\/p>\n
