I am using docker-compose.yml to create multiple running containers but failing to start Postgres docker server, with following logs and yes I have searched many related SO posts, but they didn't helped me out.

also for better consideration, I have attached my hands-on project structure:

Seems like you pulled the fresh image, where in the new image you should specify Postgres user password. You can look into Dockerhub, the image is update one month ago
postgress-11-alpine
db:
image: postgres:11-alpine
restart: always
environment:
POSTGRES_PASSWORD: example
As the error message is self expalinatory
You must specify POSTGRES_PASSWORD to a non-empty value for the
superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
or POSTGRES_HOST_AUTH_METHOD=trust use this which is not recommended.
You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
connections without a password. This is *not* recommended.
POSTGRES_PASSWORD
This environment variable is required for you to use the PostgreSQL image. It must not be empty or undefined. This environment variable sets the superuser password for PostgreSQL. The default superuser is defined by the POSTGRES_USER environment variable.
Environment Variables
#Adiii yes, you are nearly right, so I have to explicitly mentioned the environment also for the postgres image but with no db parent tag.
So here, I am explicitly mentioning the docker-compose.yaml config to help others for better understanding, also now I am using recent stable postgres image version 12-alpine, currently latest is postgres:12.3
version: '3'
services:
postgres:
image: 'postgres:12-alpine'
environment:
POSTGRES_PASSWORD: postgres_password
redis:
image: 'redis:latest'
server:
build:
dockerfile: Dockerfile.dev
context: ./server
volumes:
- /app/node_modules
- ./server:/app
environment:
- REDIS_HOST=redis
- REDIS_PORT=6379
- PGUSER=postgres
- PGHOST=postgres
- PGDATABASE=postgres
- PGPASSWORD=postgres_password
- PGPORT=5432
and so after docker-compose up the creating and running logs were as following:

Hope this would help manyone.
Adding on ArifMustafa's answer, This worked for me.
postgres:
image: 'postgres:12-alpine'
environment:
POSTGRES_PASSWORD: mypassword
expose:
- 5432
volumes:
- postgres_data:/var/lib/postgres/data/
volumes:
postgres_data:
In my case there was an error about the POSTGRES_PASSWORD (in docker-compose.yml) and the DATABASE settings for PASSWORD in the project_level settings.py file.
After providing a password in docker-compose.yml
db: # For the PostgreSQL database
image: postgres:11
environment:
- POSTGRES_PASSWORD=example
It is necessary to provide the same password to enable access to the POSTGRES database between the two containers (in my case the web application and the database it depended on). In the project_level settings.py:
# Database
# https://docs.djangoproject.com/en/2.2/ref/settings/#databases
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'postgres',
'USER': 'postgres',
'PASSWORD': 'example',
'HOST': 'db',
'PORT': 5432
}
}
To resolve the error when using the command,
docker pull postgres
You must specify POSTGRES_PASSWORD to a non-empty value for the
superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
or POSTGRES_HOST_AUTH_METHOD=trust use this which is not recommended.
You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all connections without a password. This is not recommended.
Here comes the solution for this:
$ docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres
The default postgres user and database are created in the entrypoint with initdb.
The postgres database is a default database meant for use by users, utilities and third party applications.

I've searched everywhere, tried everything, and still have this issue…
What I tried is :
Create docker volume with docker volume create --name postgres -d local and use it in my docker-compose.yml
docker-compose.yml
version: '2'
services:
postgres:
image: postgres:latest
ports:
- "5432:5432"
volumes:
- postgres:/var/lib/postgresql/data
networks:
internal_ip:
ipv4_address: 192.168.1.2
volumes:
postgres:
external: true
Add volume directly in docker compose
volume sample
volumes:
postgres:
driver: local
Using relative or absolute Windows paths
Declare multiple volumes for differents PostgreSQL folders (conf, data…)
I tried to docker compose down, restart computer, remove images, nothing change, same error.
I already checked Shared Drive box in Docker Settings.

Is anyone as a working solution ? I will continue to make it work, and update post if I found Something.
Thanks in advance.
I've finally figured out what went wrong when I tried to use a volume for PostgreSQL data.
I had no idea that we used a docker-compose.override.yml, which declare a volume with a Windows path.
So here is a working solution to have PostgreSQL on Docker for Windows, with persisted data :
version: '2'
services:
postgres:
image: postgres:11.5
ports:
- 5432:5432
volumes:
- pgdata:/var/lib/postgresql/data
- pgconf:/etc/postgresql
- pglog:/var/log/postgresql
volumes:
pgdata:
driver: local
pgconf:
driver: local
pglog:
driver: local
(no additional command required)
container_name: postgresql
image: postgres:latest
environment:
POSTGRES_PASSWORD: postgres
# volumes:
# - "./database:/var/lib/postgresql/data/"
ports:
- "5432:5432"
Comment the volumes
This work around did the trick and worked on windows, i have to bring those two lines back on mac but that's the easiest way to work for now until some real solution get pushed by docker windows or posgres docker
I was having issues connecting to my PG database in my compose file. I finally eliminated all other factors and made this bare-bones compose file:
version: '2.1'
services:
database:
image: postgres:9.5.6
environment:
POSTGRES_PASSWORD: secretpass
ports:
- 5432:5432
I then started it up with this command:
docker-compose --file docker-compose.pg.yml up --build
and it seemed to start ok:
Starting app_database_1 ...
Starting app_database_1 ... done
Attaching to app_database_1
database_1 | LOG: database system was shut down at 2017-09-22 18:48:55 UTC
database_1 | LOG: MultiXact member wraparound protections are now enabled
database_1 | LOG: database system is ready to accept connections
database_1 | LOG: autovacuum launcher started
Then from another shell, tried to connect with this command:
psql postgresql://postgres:secretpass#0.0.0.0
And got this output on my first shell where the compose was run:
database_1 | FATAL: password authentication failed for user "postgres"
database_1 | DETAIL: Connection matched pg_hba.conf line 95: "host all all 0.0.0.0/0 md5"
I have also tried to connect from another container running
Rails defined in the compose file and get the same error. I always end up with an authentication error. What am I missing?
I want to start a Postgres database using docker-compose and pass some configurations using the PGOPTIONS environment variable. My docker-compose.yml looks like this:
version: '2'
services:
db:
image: postgres
environment:
- POSTGRES_USER=dbuser
- POSTGRES_PASSWORD=dbpw
- PGOPTIONS='-c track_activities=on -c track_counts=on -c track_io_timing=on'
When I start this service using docker-compose up db I get:
db_1 | FATAL: parameter "track_io_timing" requires a Boolean value
db_1 | done
db_1 | server started
db_1 | FATAL: parameter "track_io_timing" requires a Boolean value
db_1 | psql: FATAL: parameter "track_io_timing" requires a Boolean value
It does not seem to be related to the tracking_io_timing parameter, because when I remove that one from the PGOPTIONS variable I get the same error, but for the track_counts variable. So I suspect there is something wrong with the way I declared PGOPTIONS.
Same result here when using your provided Docker-Compose file. I have tried to use the alternative syntax for defining environment variables and I do not get the errors anymore:
version: '2'
services:
db:
image: postgres
environment:
POSTGRES_USER: dbuser
POSTGRES_PASSWORD: dbpw
PGOPTIONS: "-c track_activities=on -c track_counts=on -c track_io_timing=on"

But while testing from pg-admin-iv on windows it show that 'user postgress has no password',
So is that flow from YML file is right, i want simply up the postgress and put data out side docker-container, so How to achieve this?
I would use named volumes for that instead of hosted mapped volumes:
postgres96:
image: postgres:9.6
ports:
- "5432:5432"
volumes:
- data:/var/lib/postgresql/data
environment:
POSTGRES_PASSWORD: admin#123
POSTGRES_USER: postgres
Probably you have a permission issue in your folder.
You data is saved in a volume outside the container. Then check with:
docker volume ls
Also use docker-compose as:
docker-compose up -d
Instead of &
And
docker-compose logs -f
For further information this is the last part of my log:
