springboot api in cloudrun not able to connect to postgresql instance within same GPC project

I have created a spring boot application that can connect to the postgresql14 instance (running in my GCP project) when I run the application on my local machine. Setup I used to make it work:

  • Created a postgresql14 instance with a public IP address enabled.
  • Configured the postgresql14 instance and added the IP address of my local machine to the instance’s network to enable a connection between my local machine and the SQL instance.

Using the below dependencies in pom.xml:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
    </dependency>
    <!--<dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>javax.persistence-api</artifactId>
        <version>2.2</version>
    </dependency>-->
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
    </dependency>
</dependencies>

using below details inside application.properties

spring.application.name=poc1

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=none
spring.jpa.hibernate.show-sql=true

spring.datasource.url=jdbc:postgresql://211.321.30.46:5432/postgres
spring.datasource.username=postgresuser
spring.datasource.password=password

spring.sql.init.mode=always
#spring.sql.init.schema-locations=classpath:/schema.sql
spring.sql.init.continue-on-error=true

#logging.level.org.hibernate=DEBUG
#logging.level.org.hibernate.SQL=DEBUG
#logging.level.org.hibernate.type=TRACE

But when i deploy the same application in cloud run under the same
project where my postgresql instance is running, i am getting below
error:

I’m using below configuration in my gcp project

  • role given to the cloud run service account: roles/cloudsql.client
  • role given to the user which is doing the deployment:
    roles/cloudsql.client

    Issue has been resolved with below addition:

    • Added 2 more dependencies in my pom.xml as shown below

       <dependency>
     <groupId>com.google.cloud</groupId>
     <artifactId>spring-cloud-gcp-dependencies</artifactId>
     <version>5.5.0</version>
     <type>pom</type>
 </dependency>
 <dependency>
     <groupId>com.google.cloud</groupId>
     <artifactId>spring-cloud-gcp-starter-sql-postgresql</artifactId>
     <version>5.5.0</version>
 </dependency>

    • Added two more properties in my application.property file

    spring.cloud.gcp.sql.instance-connection-name = <connection name>
spring.cloud.gcp.sql.database-name=<db name>

    And it started working from CloudRun instance.

    Clicking "Public IP" just assigns a public IP to the DB. It does not make networking resources needed to address the DB directly from public internet.

    "Public IP" allows you to use Cloud SQL Proxy to connect to the DB. This is what you should use.

    If you go to GCP UI. Click Connections -> Security, you will see this: enter image description here
