I have pulled a docker image that runs an MS SQL from docker hub:
docker pull mcr.microsoft.com/mssql/server:2017-latest
docker run --name some-db -e ACCEPT_EULA=Y -e MSSQL_SA_PASSWORD=Aamerge1234 -e MSSQL_PID=Developer -d -p 1433:1433 mcr.microsoft.com/mssql/server:2017-latest
The container runs fine, I added a strong password as required.
This is the python code I am using to connect with the database using pyodbc:
import pyodbc
server = 'localhost:1433'
# database = ''
username = 'sa'
password = 'Aamerge1234'
conn = pyodbc.connect('DRIVER={SQL Server Native Client 11.0};SERVER='+server+';UID='+username+';PWD='+ password)
I have omitted the variable database because mssql creates several.
I tried using the following ODBC drivers:
ODBC Driver 17 for SQL Server
SQL Server
However, it always returns error:
OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [53]. (53) (SQLDriverConnect); [08001] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0); [08001] [Microsoft][ODBC Driver 17 for SQL Server]A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

Trying to spin up an mssql server with a docker-compose file:
version: "3.7"
services:
sqlserver:
image: mcr.microsoft.com/mssql/server:2017-latest
container_name: sqlserver
user: root
ports:
- "1433:1433"
environment:
SA_USERNAME: sa
SA_PASSWORD: Dev1234!
ACCEPT_EULA: Y
MSSQL_AGENT_ENABLED: 'true'
volumes:
- ./volumes/data2:/var/opt/mssql/data
- ./volumes/backup:/var/opt/mssql/Backup
The server is up and running successfully, But when tried to connect with powershell script code:
$connectionString = "Data Source=localhost,1433;User ID=sa;Password=Dev1234!;"
$connection = New-Object System.Data.SqlClient.SqlConnection($connectionString)
$connection.Open();
It throws error like:
"A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name
is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - The
remote computer refused the network connection.)"
That is, it fails when trying to connect with 'localhost' as host, it is successfully connecting when "127.0.0.1" is specified as host.
The same happens when I tried to connect with SQL server management studio.
My docker engine is running in wsl, an ubuntu distro specifically. There is MySQL and different other servers already spun up which I can access with localhost.
Is there anything I need to specify in docker-compose to make this work? When checking documentation, there are no params aligned to it as I see.
I know this has been covered multiple times, but I still cannot execute an SQL script on docker deployment.

Unable to connect to mssql server from qt application in ubuntu 20.04

The connection is definitely present, because it was possible to connect through DDbeaver.
Can anyone help me in this situation?
Code:
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC3");
db.setConnectOptions();
QString serverName = "566***";
QString ipName = "tcp:192.168.144.101,1433";
QString dbName = "St***";
QString connectionString = QString("DRIVER={ODBC Driver 18 for SQL Server};Server=%1;Database=%2;").arg(ipName).arg(dbName);
db.setDatabaseName(connectionString);
db.setUserName("sa");
db.setPassword("top123TOP");
if (db.open())
{
qDebug() << "Correct connection";
}
else
{
QString error = db.lastError().text();
qDebug() << error;

We have a real old SQL server out there . The SQL Server show's version 10.50.2550.0, i think it's SQL Server 2008 R2. I had to use TLSv1 to connect to the server. I also had to do a "systemctl restart apache2" to get it to take affect. TLSv1.1 did not work with my MSSQL server version.
Error message: Connection failed: SQLSTATE[08001]: [Microsoft][ODBC Driver 17 for SQL Server]SSL Provider: [error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol]Database Connection Error

What's going wrong in this? Thank you in advance.
This is my docker-compose.yml file:

As you can see, I'm using the official docker image for MS SQL Server, mcr.microsoft.com/mssql/server.
My laptop is Ubuntu 20.04 LTS.
I run docker-compose up -d and then docker exec -it db sh to get interactive shell.
Then I write this command:
/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P 'lksU2o412f7tBj58t07B'
And I get this response:
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Login timeout expired.
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : TCP Provider: Error code 0x2749.
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online..
This is the official image and I have not changed anything.
Also in my api container, I can ping db or Database. But I can't telnet port 1433.
Also from my host machine I can telnet localhost 1433, but I get this response:
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
This is a terrible experience in working with containers from Microsoft. Aren't containers supposed to work out of the box? Isn't container technology there only to solve these stupid problems?
What should I do?
