Taiga don't connect to postgres

[evandroteixeira1710]

Good morning people,
Today I started testing Taiga for the company I work for, created taiga.yml and went up with the docker-compose -f taiga.yml up -d.
When I check the taiga log, it is looping for not connecting to the database.
"Failed to connect to database server or database does not exist.
Running database check
Connecting to database:
dbname = 'taigadb' user = 'taiga' host = 'localhost' password = 'password'
Traceback (most recent call last):

conn = psycopg2.connect (conn_string)
File "/usr/local/lib/python3.5/site-packages/psycopg2/init.py", line 130, in connect
conn = _connect (dsn, connection_factory = connection_factory, ** kwasync)

My taiga.yml

version: '3'

taiga:
container_name: Taiga
image: benhutchins / taiga
restart: always
build: ../
ports:

• 8085: 80

- 443: 443 # To enable SSL, uncomment this line. See "Enable SSL" below.

depends_on:

• db

To enable taiga-events, uncomment the following lines:

- events

- rabbit

- redis

environment:

Hostname for your instance of Taiga. Required.

TAIGA_HOSTNAME: localhost

Database variables. Required.

TAIGA_DB_HOST: localhost
TAIGA_DB_NAME: taigadb
TAIGA_DB_USER: taiga
TAIGA_DB_PASSWORD: password

# Enable SSL internally, within the Docker container. Optional.
# This is not great. I suggest using something on top of this
# to enable SSL. See the example example-nginx-ssl.conf file
# for an alternative way to enable SSL.
# TAIGA_SSL: 'True'

# Enable SSL externally, preferred method
# TAIGA_SSL_BY_REVERSE_PROXY: 'True'

volumes:
# Media and uploads directory. Required (or you will lose all uploads)
- ./media:/usr/src/taiga-back/media

# Taiga configuration directory. Makes it easier to change configuration.
- ./taiga-conf:/taiga

db:
container_name: Postgres_taiga
image: postgres: 9.6
environment:
POSTGRES_DB: taigadb
POSTGRES_USER: taiga
POSTGRES_PASSWORD: password
ports:

  volumes:

OBS. I can access via pgadmin and connecting to postgres as well.
