I'm running a simple Docker Compose script to instantiate Postgres and pgAdmin for local development.
It works fine on Windows via Power Shell as administrator, but in Linux I'm getting this error:
Unable to connect to server connection to server at '172.18.0.3' port 5432 failed: timeout expired
How to solve it?

I'd like to run a postgre db server on localhost:5432. It used to work, then I updated to mac os 13.2. Now if I enter my password to connect to local postgre server, the following error being shown:
Anybody knows how to solve this issue?
I tried to start the postgre sql local server.
i have an issue
i have a container that has a web application running and a postgres db, when i launch the webapp is connected in database correctly, but when in local i tried using a pgadmin that is install on my machine and i try to connect to database of container it gives me an error connection
error message
TIPS
the container has the port-forward of database
i tried using both localhost and the ip of container as host when initialize connetion using pgAdmin
I have no idea how to do that, someone can help me
I started a process on the host that listens on a Unix socket:
/cloud_sql_proxy -enable_iam_login -dir=/var/run/cloudsql -instances=project:region:server
I confirmed I can make a connection with psql: psql "sslmode=disable host=/var/run/cloudsql/project:region:server user=myuser#project.iam dbname=mydb
I need to connect to Postgres over this socket with npgsql but inside a container.
I'm using this connection string:
string DBConnectionString = #"
User ID=myuser#project.iam;
Host=/var/run/cloudsql/project:region:server;
Database=mydb;
Port=5432
";
using (var connection = new NpgsqlConnection(DBConnectionString))
connection.Query("SELECT * FROM mytable ORDER BY zzz");
Running this application locally on the host with this connection string works as expected- it can connect to the Unix socket and query the DB without issue. From inside a container it is not working.
I start the container trying to mount the file for the Unix socket:
docker run \
--mount type=bind,source="/var/run/cloudsql",target="/var/run/cloudsql" \
"myimage"
But I'm getting this error:
[00:13:46 FTL] Npgsql.NpgsqlException (0x80004005): Exception while connecting
---> System.Net.Internals.SocketExceptionFactory+ExtendedSocketException (111): Connection refused /var/run/cloudsql/project:region:server/.s.PGSQL.5432
at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)
When I look at the process using the socket (cloud SQL proxy) I see no output during the attempt. When to connect to the socket from the host with the app or psql I see logs for login attempts. So maybe the socket isn't mounted correctly?
Update: also works fine with k8s
Just to add to this, this also works in k8s. In my manifest I just create a shared volume. I have a container running the app and another container running the cloud SQL proxy and mount the volume to both and it just works. So I'm wondering if this is some local docker perms issue or something?
I have a Linux instance in AWS Lightsail and I have started up a PostgreSQL database on my LightSail hosted Linux server. On my local Windows 10 machine, I have a Postgresql server as well. When I am attempting to connect to the AWS Postgresql server on Lightsail following the steps described here:
https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-connecting-to-your-postgres-database
On my pgAdmin (my pgAdmin is acting as the client while the Postgresql database that I have on AWS is the server), I am seeing the following error message:
Error saving properties
Unable to connect to the server:
timeout expired
Please note, my database is hosted by Lightsail and not by AWS RDS.
use SSL tunnel with your ip and pem file under SSH Tunnel Tab
Under connection user the ip 127.0.0.1 with your postgres username and password.
I have Amazon EC2 instance running Ubuntu. I have installed and configured PostgreSQL.
Contents of the file /etc/postgresql/9.3/main/pg_hba.conf:
local all all md5
host all all 0.0.0.0/0 md5
Also in postgresql.conf
I have set listen_addresses='*'.
The test command below is successfully starting psql console.
psql -U postgres testdb
Now I am trying to connect pgAdmin4 from MacOS.
I have created a SSH tunnel with following command:
ssh -i ~/.ssh/test.pem -fN -L 5433:localhost:5432 ubuntu#mytestdomain.com
Now I have following details in pgAdmin:
When I save, I get this output:
Unable to connect to server: server closed the connection unexpectedly. This probably means the server terminated abnormally before or while processing the request.
What am I doing wrong ?
Here is the solution,
install pgadmin 4 into your system. and configure the below-added configurations. if the below configurations do not work then please check that DB user permissions on AWS. because of the restriction on IP level so it may not be able to access.
