I am facing below issue in docker with postgres while trying to open localhost:3000
could not connect to server: Connection refused Is the server running on host
"localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432? could
not connect to server: Cannot assign requested address Is the server running
on host "localhost" (::1) and accepting TCP/IP connections on port 5432?
Below the docker-compose file i am using
version: '3'
volumes:
postgres_data: {}
services:
redis:
image: redis
command: redis-server
ports:
- "6379:6379"
app:
build:
context: .
dockerfile: /Users/admin/git/generic/myapp/docker/app/Dockerfile
depends_on:
- db
ports:
- 3000:3000
db:
image: postgres
volumes:
- postgres_data:/var/lib/postgresql/data
web:
build:
context: .
dockerfile: /Users/admin/git/generic/myapp/docker/web/Dockerfile
depends_on:
- app
ports:
- 80:80
Can anyone help regarding this?
Probably, you must to define 5432 port in your docker-compose.
ports:
- 80:80
- 5432:5432
Use this configuration for docker-compose.yml:
version: '3.5'
services:
redis:
image: redis
command: redis-server
ports:
- "6379:6379"
app:
build:
context: .
dockerfile: /Users/admin/git/generic/myapp/docker/app/Dockerfile
depends_on:
- db
ports:
- "3000:3000"
