After running docker-compose up. I get the error below
FATAL: password authentication failed for user "postgres"
DETAIL: Connection matched pg_hba.conf line 95: "host all all all md5"
Waiting for db
Here is my docker-compose.yml file
version: '3'
services:
redis:
image: redis

I used postgres image version 12-alpine and it somehow worked
image: postgres:12-alpine
environment:
- POSTGRES_USER = postgres

I try to connect to my Postgres database built by docker in DataGrip but I get connection error.
Here is my application.yml file:
spring:
jpa:
database: POSTGRESQL
show-sql: true
hibernate:
ddl-auto: update
datasource:
url: jdbc:postgresql://db:5432/postgis_db?createDatabaseIfNotExist=true&useSSL=false&allowPublicKeyRetrieval=true
username: postgres
password: postgres
Here is docker-compose.yml file:
version: '3.8'
services:
db:
image: postgres:latest
restart: always
volumes:
- db:/var/lib/postgresql/data
environment:
POSTGRES_DB: postgis_db
POSTGRES_USER: postgres

And the error I get:
Does anybody knows how to solve this?
Connecting to this db by shell works fine:
docker exec -it a37 psql -U postgres postgis_db
Please check pg_hba.conf file, you have to allow connections from all hosts for this user, by default it is restricted to localhost.
i have this docker-compose file:
version: '3.7'
services:
db:
image: "postgres:9.6"
container_name: postgres-container
ports: ["6543:5432"]
environment:
- POSTGRES_USER=odoo
- POSTGRES_PASSWORD=admin
- POSTGRES_DB=odoo
restart: always
volumes:
- ./data/postgres:/var/lib/postgresql/data
odoo:
#build: ./odoo-container
image: odoo-image
container_name: odoo-container
ports: ["8069:8069"]
tty: true
command: opt/odoo/odoo-bin -c opt/odoo.conf -d teste
depends_on:
- db
the problem is that when i start docker compose, my db service runs and when docker runs the odoo service i get an error:
psycopg2.OperationalError: FATAL: the database system is starting up
and when i restart the odoo container, its works
im added the restart method, and works:
odoo:
#build: ./odoo-container
image: odoo-image
container_name: odoo-container
ports: ["8069:8069"]
command: opt/odoo/odoo-bin -c opt/odoo.conf -d teste

I created postgres_net via docker network create -d bridge postgres_net
Why am I doing this? I want to create apps with same docker-compose structure without creating a postgresql db for each, if I put them together like below it will work.

I can connect to the Db via pgadmin, but can't understand why myapp cannot connect, please help

You have not properly defined network in First compose file(App compose). You have specified postgres_net as network_mode: postgres_net which is invalid. You need to specify it properly like in the second compose file.
Corrected compose file will be:
APP Docker-Compose
version: "3"
services:
app:
image: myapp
container_name: myapp_Container
ports:

environment:

networks: # declare network here
- postgres_net

postgres_net:
external: true
DB Docker-Compose

services:

this config worked perfectly

as probably people may know, one may run the docker-compose files in a different folder per application, because docker-compose cares about the path and overwrites the last container you created in a given folder.
I try to up postgresql and adminer via docker container. But from adminer I cannot enter to postgresql with password and user I whote.
SQLSTATE[08006] [7] FATAL: password authentication failed for user "root"
I tried all.

This docker-compose configuration works well.
Try recreating it from scratch:
Delete ./postgres folder
docker-compose stop
docker-compose down
docker-compose up -d
I have a docker-compose file with services for python, nginx, postgres and pgadmin:

pgadmin:
When I run docker-compose up and visit localhost:5050, I see the pgadmin interface. When I try to create a new server there, with localhost or 0.0.0.0 as host name and 5431 as port, I get an error "Could not connect to server". If I remove these and instead enter postgres in the "Service" field, I get the error "definition of service "postgres" not found". How can I connect to the database with pgadmin?
the docker container name changes when you run docker-compose to prefix the folder name (to keep container names unique). You could force the name of the container with container_name property
version: "3"
services:
# postgres database
postgres:
image: postgres:12.3
container_name: postgres
environment:
- POSTGRES_DB=admin
- POSTGRES_USER=admin
- POSTGRES_PASSWORD=admin
- POSTGRES_HOST_AUTH_METHOD=trust # allow all connections without a password. This is *not* recommended for prod
volumes:
- database-data:/var/lib/postgresql/data/ # persist data even if container shuts down
ports:
- "5432:5432"
# pgadmin for managing postgis db (runs at localhost:5050)
# To add the above postgres server to pgadmin, use hostname as defined by docker: 'postgres'
pgadmin:
image: dpage/pgadmin4
container_name: pgadmin
environment:
- PGADMIN_DEFAULT_EMAIL=admin
- PGADMIN_DEFAULT_PASSWORD=admin
- PGADMIN_LISTEN_PORT=5050
ports:
- "5050:5050"
volumes:
database-data:
Another option is to connect the postgres container to localhost with
network_mode: host
But you lose the nice network isolation from docker that way
Be careful that the default postgres port is 5432 not 5431. You should update the port mapping for the postgres service in your compose file. The wrong port might be the reason for the issues you reported. Change the port mapping and then try to connect to postgres:5432. localhost:5432 will not work.
