connection string for sqlserver in Docker container

Question

I'm using Visual Studio 2017 for mac with dotnet Core and EF Core. After setting up the mssql image in Docker container , I was trying to add the connection string but throwing connection error. I tried with different options such as ip address , container name , host name etc. as server name but none of them worked.

 "Default": "Server=172.17.0.2; Database=ERPDb; User=sa; Password =******;" 

with container name

 "Default": "Server=ecstatic_hermann; Database=ERPDb; User=sa; Password=******;" 

with hostname :

 "Default": "Server=f45840a59623; Database=ERPDb; User=sa; Password=******;" 

While connecting through using localhost in Terminal its successfully connecting

$ mssql -s localhost -p Technocrat123 Connecting to localhost...done  sql-cli version 0.6.2 Enter ".help" for usage hints. 

But when running the application the connection fails.

Appreciate any help. Thanks in advance.

If using localhost then error is

Login failed for user ''. Reason: An attempt to login using SQL authentication failed. Server is configured for Integrated authentication only. 

Answer 1

sudo docker pull microsoft/mssql-server-linux:2017-latest docker run \   -e 'ACCEPT_EULA=Y' \   -e 'MSSQL_SA_PASSWORD=YourSTRONG!Passw0rd' \   -p 1401:1433 \   -n sql1 \   -d microsoft/mssql-server-linux:2017-latest 

then,

private static string _connStr = @"   Server=127.0.0.1,1401;   Database=Master;   User Id=SA;   Password=YourSTRONG!Passw0rd";
