nodejs with docker and postgress: Error: getaddrinfo ENOTFOUND - node.js

Question

Hello I don't know what else to do to resolve this error:
ci-api | Error: getaddrinfo ENOTFOUND ${DB_HOST}
ci-api | at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:66:26) {
ci-api | errno: 'ENOTFOUND',
ci-api | code: 'ENOTFOUND',
ci-api | syscall: 'getaddrinfo',
ci-api | hostname: '${DB_HOST}'
ci-api | }
I have a .env file with the following variables:
.env file:
SERVER_PORT=4000
DB_HOST=db-pg
DB_PORT=5432
DB_USER=spirit
DB_PASS=api
DB_NAME=emasa_ci
DockerFile:
#building code
FROM node:lts-alpine
ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.7.3/wait /wait
RUN chmod +x /wait
RUN mkdir -p /home/node/api && chown -R node:node /home/node/api
WORKDIR /home/node/api
COPY ormconfig.json .env package.json yarn.* ./
USER node
RUN yarn
COPY --chown=node:node . .
EXPOSE 4000
**My `docker-compose`:**
version: '3.7'
services:
db-pg:
image: postgres:12
container_name: db-pg
ports:
- '${DB_PORT}:5432'
environment:
ALLOW_EMPTY_PASSWORD: 'no'
POSTGRES_USER: ${DB_USER}
POSTGRES_PASSWORD: ${DB_PASS}
POSTGRES_DB: ${DB_NAME}
volumes:
- ci-postgres-data:/data
ci-api:
build: .
container_name: ci-api
volumes:
- .:/home/node/api
ports:
- '${SERVER_PORT}:${SERVER_PORT}'
depends_on:
- db-pg
command: sh -c "/wait && yarn dev"
environment:
WAIT_HOSTS: db-pg:5432
logging:
driver: 'json-file'
options:
max-size: '10m'
max-file: '5'
volumes:
ci-postgres-data:
And, this is my ORM CONFIG:
{
"type": "postgres",
"host": "${DB_HOST}",
"port": "${DB_PORT}",
"username": "${DB_USER}",
"password": "${DB_PASS}",
"database": "${DB_NAME}",
"synchronize": true,
"logging": false,
"entities": ["dist/src/entity/**/*.js"],
"migrations": ["dist/src/migration/**/*.js"],
"subscribers": ["dist/src/subscriber/**/*.js"],
"cli": {
"entitiesDir": "dist/src/entity",
"migrationsDir": "dist/src/migration",
"subscribersDir": "dist/src/subscriber"
}
}
I can't imagine the reason for this error, I basically added a script for the node to start after the start of my Postgres where db-pg is my Postgres image name.
I can't imagine what went wrong, could someone help me with this?
P.S.: I use typescript/typeorm

{
"type": "postgres",
"host": "db-pg",
"port": 5432,
"username": "spirit",
"password": "api",
"database": "emasa_ci",
"synchronize": true,
"logging": false,
"entities": ["dist/src/entity/**/*.js"],
"migrations": ["dist/src/migration/**/*.js"],
"subscribers": ["dist/src/subscriber/**/*.js"],
"cli": {
"entitiesDir": "dist/src/entity",
"migrationsDir": "dist/src/migration",
"subscribersDir": "dist/src/subscriber"
}
}
the problem was in my
ormconfig.json (was using .env)
