We can't connect to an external mssql database from inside our docker container.

Update: This issue seems to be mssql2016 related. We have connected to a 2019 box and run dbal queries with no problems. We can also run queries on a dockerised 2017 instance. We still can't completely rule out a config issue though

Attempts to connect with Python and nodeJS work. We can also connect from php outside of docker. From the experiments below, it looks like we can find the database, but it isn't responding. If we try and connect to a nonesnse name we get a network error database not found. If we use the ip address we get a timeout from an unresponsive server.

Connections to a sqlserver database in another docker container in the same stack work fine.

We can resolve the server name (You will need to install dnsutils in the container to try this)

$ docker exec nslookup srv01647 Server: 127.0.0.11
Address: 127.0.0.11#53

Non-authoritative answer:
Name: srv01647.soton.ac.uk Address: 192.168.170.29

We can also ping it.

running a dbal query from a bare bones symfony app inside a docker container (doctrine installed)

using this docker-compose.yml config:

    php:
    container_name: <container_name>
    build: # we are specifying the version in the Dockerfile
      context: .
      target: php
      dockerfile: Dockerfile
#      network: host
    volumes:
      - .:/srv/ioda
    working_dir: /srv/ioda
    ports:
      - "8000:8000"
#    extra_hosts:
#      - "nihrdw:192.168.170.29"

with doctrine installed

and this connection url (.env): DATABASE_URL="sqlsrv://<username>:<password>@192.168.170.29:1433/INFONIHR_DW?serverVersion=13.00.6430.9&charset=UTF-8&driverOptions[TrustServerCertificate]=1"

produces this response:

docker exec <container_name> symfony console dbal:run-sql 'select 1'

using the below URL with a gibberish database name produces a different result DATABASE_URL="sqlsrv://<username>:<password>@wibble:1433/INFONIHR_DW?serverVersion=13.00.6430.9&charset=UTF-8&driverOptions[TrustServerCertificate]=1"

produces a different result: the TCP Provider: Error code is now '0x2AFA':

Error 0x2AFA means the host is unreachable Error 0x2746 means the host was reached but the client timed out due to non-response

installed openssl as per this https://stackoverflow.com/questions/74708033/error-code-0x2746-10054-when-trying-to-connect-to-sql-server-2014-via-odbc-fro

also tried switching msodbcsql18 to msodbcsql17 still 0x2746

attempts to connect using isql set up the datasource by adding the floowing to etc/odbc.ini:

[MSSQLServer]
Driver = ODBC Driver 18 for SQL Server
Trace = No
Server = 192.168.170.29
Port = 1433
User = <usename>
Password = <password>

run this: $ docker exec <container name> isql -v MSSQLServer which produces:

[ISQL]ERROR: Could not SQLConnect
[08001][unixODBC][Microsoft][ODBC Driver 18 for SQL Server]TCP Provider: Error code 0x2746
[08001][unixODBC][Microsoft][ODBC Driver 18 for SQL Server]Client unable to establish connection. For solutions related to encryption errors, see https://go.microsoft.com/fwl
ink/?linkid=2226722

Error code 0x2746 means we found a server on the network but timed out... changing the server option above to an arbitrary string produced a different response:

docker exec <container name> isql -v MSSQLServer gives us this:

[S1T00][unixODBC][Microsoft][ODBC Driver 18 for SQL Server]Login timeout expired
[08001][unixODBC][Microsoft][ODBC Driver 18 for SQL Server]TCP Provider: Error code 0x2AF9

This error code means we couldn't find the destination on the network
