Use docker exec to run sqlcmd to change the password using Transact-SQL. In the following example, the old and new passwords are read from user input. Use the docker exec -it command to start an interactive bash shell inside your running container. In the following example sql1 is name specified by the --name parameter when you created the container. Once inside the container, connect locally with sqlcmd. Sqlcmd is not in the path by default, so you have to specify the full path.
The following sections walk you through using sqlcmd and Transact-SQL to create a new database, add data, and run a query. From the sqlcmd command prompt, paste the following Transact-SQL command to create a test database:. The previous two commands were not executed immediately. Type GO on a new line to execute the previous commands:.
From the sqlcmd command prompt, switch context to the new TestDB database:. From the sqlcmd command prompt, enter a query that returns rows from the Inventory table where the quantity is greater than To exit the interactive command-prompt in your container, type exit.
Your container continues to run after you exit the interactive bash shell. The following steps use sqlcmd outside of your container to connect to SQL Server running in the container.
These steps assume that you already have the SQL Server command-line tools installed outside of your container. The same principles apply when using other tools, but the process of connecting is unique to each tool. Find the IP address for the machine that hosts your container.
On Linux, use ifconfig or ip addr. On Windows, use ipconfig. For this example, install the sqlcmd tool on your client machine. For more information, see Install sqlcmd on Windows or Install sqlcmd on Linux.
Run sqlcmd specifying the IP address and the port mapped to port in your container. In this example, that is the same port, , on the host machine. If you specified a different mapped port on the host machine, you would use it here. You will also need to open the appropriate inbound port on your firewall to allow the connection. If you want to remove the SQL Server container used in this tutorial, run the following commands:. Stopping and removing a container permanently deletes any SQL Server data in the container.
If you need to preserve your data, create and copy a backup file out of the container or use a container data persistence technique. After you have tried using the SQL Server container image for Docker, you might want to know how Docker is used to improve development and testing.
The following video shows how Docker can be used in a continuous integration and deployment scenario. For a tutorial on how to restore database backup files into a container, see Restore a SQL Server database in a Linux Docker container. Explore other scenarios, such as running multiple containers, data persistence, and troubleshooting. Prerequisites Docker Engine 1.
For more information, see Install Docker. For more information on hardware requirements and processor support, see SQL Server Hardware and software requirements. Docker overlay2 storage driver. This is the default for most users. If you find that you are not using this storage provider and need to change, see the instructions and warnings in the docker documentation for configuring overlay2.
Minimum of 2 GB of disk space. Pull and run the container image Before starting the following steps, make sure that you have selected your preferred shell bash, PowerShell, or cmd at the top of this article. Note If you are using PowerShell Core, replace the double quotes with single quotes.
