I'm using Spring Boot App which is deployed on Cloud Run (GCP). The app is establishing the database connection through Cloud SQL Proxy using IAM authentication.
The goal is to implement Unix Socket Connection instead of TCP for connecting with Cloud SQL.
Bellow is the application.yml content:
spring:
cloud:
gcp:
sql:
jdbc:
enabled: false
database-name: db-name
enable-iam-auth: true
instance-connection-name: instance-name
datasource:
url: jdbc:postgresql:///db-name?unixSocketPath=/cloudsql/instance-name/.s.PGSQL.5432&socketFactory=com.google.cloud.sql.postgres.SocketFactory&enableIamAuth=true&sslmode=disable&cloudSqlInstance=instance-name
username: my-username
password: ""
type: com.zaxxer.hikari.HikariDataSource
hikari:
maximum-pool-size: 10
After the deployment in the logs I got an info message: "Connecting to Cloud SQL instance [instance-name] via unix socket at..." which makes sense because the unixSocketPath property is provided in JDBC URL.
The error that I'm getting is that password is not provided (but I'm using IAM auth so the password is not needed). Here is the complete stack trace:
org.postgresql.util.PSQLException: The server requested password-based authentication, but no password was provided by plugin null

Any ideas how to solve this issue?
P.S. If I remove JDBC URL and enable GCP SQL Auto-Configuration everything works fine but the idea is to use unix-socket connection instead of TCP.

References:
Cloud SQL Team has provided a workaround for the issue, which consists of using the latest version of the Java connector that has a fix applied.
Release notes can be found on this link: https://github.com/GoogleCloudPlatform/cloud-sql-jdbc-socket-factory/releases
Fix is applied in version v1.11.1.
If you're using Spring Cloud GCP Dependency (like I am in this project) you can find release notes on this link: https://github.com/GoogleCloudPlatform/spring-cloud-gcp/releases. Versions v3.5.1 and v4.3.1 use the proper Java Connector with fixed issue.
This means that you don't need any custom data source configuration, just use YML props as before:
spring:
cloud:
gcp:
sql:
database-name: db-name
enable-iam-auth: true
instance-connection-name: instance-name
datasource:
hikari:
maximum-pool-size: 10
