Success! PostgreSQL is Running Correctly

Great news! Your PostgreSQL container is now running successfully. The logs show that:

The database cluster was initialized properly
The server started successfully
The database was created
PostgreSQL is now listening on port 5432 and ready to accept connections

What Worked

It looks like using Docker named volumes (Solution 1) resolved the permission issues. This is the recommended approach for PostgreSQL containers because:

Docker manages the volume permissions automatically
It avoids host filesystem permission conflicts
It's more portable across different environments
Data persistence is handled properly by Docker

Next Steps

Now that your PostgreSQL database is running, you can:

Connect to your database:
docker exec -it postgres_db psql -U postgres -d mydb
Verify your frontend can connect to the database:
docker logs frontend
Create database tables and schemas:
docker exec -it postgres_db psql -U postgres -d mydb -c "CREATE TABLE test (id SERIAL PRIMARY KEY, name TEXT);"
Back up your database when needed:
docker exec -it postgres_db pg_dump -U postgres -d mydb > backup.sql
Monitor your database:
docker exec -it postgres_db psql -U postgres -d mydb -c "SELECT * FROM pg_stat_activity;"

Your Docker setup is now working correctly, and you should be able to proceed with your application development.

Troubleshooting Port 3001 Access Issue

I see you have multiple containers running, including a frontend service on port 3001 that you can't access using your server IP. Let's troubleshoot this issue:

Possible Causes and Solutions

1. Check if the application is running correctly

First, check the logs of your frontend container:

docker logs frontend_talod

Look for any errors or messages indicating the application isn't starting properly.

2. Verify the application is binding to the correct address

Your application might be binding only to localhost (127.0.0.1) inside the container instead of 0.0.0.0 (all interfaces). Check your application configuration:

docker exec -it frontend_talod sh -c "netstat -tulpn | grep 3001"

If it shows 127.0.0.1:3001 instead of 0.0.0.0:3001, you need to modify your application to bind to all interfaces.

3. Check firewall settings

Your server firewall might be blocking port 3001:

sudo ufw status
# or
sudo iptables -L -n

If the port is blocked, allow it:

sudo ufw allow 3001/tcp

4. Verify Docker port mapping

The Docker port mapping looks correct in your docker ps output (0.0.0.0:3001->3001/tcp), but let's double-check your docker-compose file:

services:
  frontend:
    # ...
    ports:
      - "3001:3001"  # Make sure it's not "127.0.0.1:3001:3001"

5. Test local connectivity

Check if you can access the service locally on the server:

curl http://localhost:3001

If this works but remote access doesn't, it's likely a firewall or network configuration issue.

6. Check your server's network interfaces

Make sure your server has the correct IP address:

ip addr show

7. Try accessing with explicit protocol

Make sure you're using the correct protocol (http or https):

http://your-server-ip:3001

Let me know the results of these checks, and we can further troubleshoot the issue.

i in Dockerfile expose also 3001 but in logs:
tapovan1234@tapovan:~/talod-tapovan$ docker logs frontend_talod

teacher-attendance@0.1.0 start
next start

▲ Next.js 15.2.3
