FATAL: password authentication failed for user "admin" Docker and Spring boot-CodePudding

I have a sping boot application and here is my application.yml file.


# postgres sql connection
spring:
  datasource:
    password: password
    url: jdbc:postgresql://127.0.0.1:5432/todos
    username: admin
  jpa:
    hibernate:
      ddl-auto: create #create
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQLDialect
        format_sql: true
    show-sql: true
# Configuring the port for our server
server:
  port: 3001

And here is my docker-compose.yml file:

version: "3.9"
services:
  postgresdb:
    image: postgres:14.4-alpine
    container_name: pgsql
    restart: always
    volumes:
      - ./db/init.sql:/docker-entrypoint-initdb.d/0_init.sql
      # - $HOME/database:/var/lib/postgresql/data
    ports:
      - "5232:5432"
    expose:
      - "5232"
    environment:
      POSTGRES_DB: todos
      POSTGRES_USER: admin
      POSTGRES_PASSWORD: password
      SERVICE_NAME: postgresdb
    networks:
      - internalnet

networks:
  internalnet:
    driver: bridge

My postgres container is already running, but when i try to connect my spring application with docker i get the following error:


org.postgresql.util.PSQLException: FATAL: password authentication failed for user "admin"

If i run ps command:

CONTAINER ID   IMAGE                  COMMAND                  CREATED         STATUS                          PORTS                               NAMES
a7035cd521a6   postgres:14.4-alpine   "docker-entrypoint.s…"   7 minutes ago   Up 7 minutes                    5232/tcp, 0.0.0.0:5232->5432/tcp    pgsql

What may be possibly my problem here?

CodePudding user response：

Your spring boot application should be contacting the postgres db on port 5232 since that is what you are port forwarding from the db container (not 5432).
