Deploy PostgreSQL on KubeSphere
PostgreSQL is a powerful, open-source object-relational database system, which is famous for reliability, feature robustness, and performance.
This tutorial walks you through an example of how to deploy PostgreSQL from the App Store of KubeSphere.
- Please make sure you enable the OpenPitrix system.
- You need to create a workspace, a project, and a user account (
project-regular) for this tutorial. The account needs to be a platform regular user and to be invited as the project operator with the
operatorrole. In this tutorial, you log in as
project-regularand work in the project
demo-projectin the workspace
demo-workspace. For more information, see Create Workspaces, Projects, Users and Roles.
Step 1: Deploy PostgreSQL from the App Store
On the Overview page of the project
demo-project, click App Store in the upper-left corner.
Find PostgreSQL and click Install on the App Information page.
Set a name and select an app version. Make sure PostgreSQL is deployed in
demo-projectand click Next.
In App Settings, specify persistent volumes for the app and record the username and the password, which will be used later to access the app. When you finish, click Install.
NoteTo specify more values for PostgreSQL, use the toggle switch to see the app's manifest in YAML format and edit its configurations.
Wait until PostgreSQL is up and running.
Step 2: Access the PostgreSQL database
To access PostgreSQL outside the cluster, you need to expose the app through a NodePort first.
Go to Services and click the service name of PostgreSQL.
Click More and select Edit External Access from the drop-down list.
Select NodePort for Access Method and click OK. For more information, see Project Gateway.
Under Ports, you can see the port is exposed, which will be used in the next step to access the PostgreSQL database.
Expand the Pod menu under Pods and click the Terminal icon. In the pop-up window, enter commands directly to access the database.
NoteYou can also use a third-party application such as SQLPro Studio to connect to the database. You may need to open the port in your security groups and configure related port forwarding rules depending on where your Kubernetes cluster is deployed.
For more information, see the official documentation of PostgreSQL.
