Reading Time: 11 minutes Over the past few months, I’ve started using for all my local development work. Previously I had experimented with VMs, but because we deal in microservices, running six or more VMs on my Macbook Pro was starting to get cumbersome. Docker has clear advantages in system utilization, but I also like that my local configuration can easily be used on servers and continuous integration environments as well. I’m not the only developer discovering the advantages to containerized workflows; Docker,. While most of my work with Docker has been in local development, we recently had our first opportunity to ship a new production service with it. In Part 1 of this tutorial, I’ll walk you through the process of setting up a Laravel PHP command-line application to run in Docker. Look for Part 2 next week, when I’ll go over the process for continuous integration and deployment using.
Feb 17, 2018 - The equivalent commands docker-compose run and docker-compose exec automatically assign a terminal so you can just run the following to. This is done with the docker rmi command, like so: sudo docker rmi IMAGE_ID. Where IMAGE_ID is the idea of the image. Remember, you get the IMAGE ID from the docker images command. You can also.
In this quickstart, you use Docker to pull and run the SQL Server 2019 preview container image,. Then connect with sqlcmd to create your first database and run queries. This image consists of SQL Server running on Linux based on Ubuntu 16.04.
It can be used with the Docker Engine 1.8+ on Linux or on Docker for Mac/Windows. This quick start specifically focuses on using the SQL Server on linux image. The Windows image is not covered, but you can learn more about it on the. Prerequisites. Docker Engine 1.8+ on any supported Linux distribution or Docker for Mac/Windows. For more information, see.
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, please see the instructions and warnings in the. Minimum of 2 GB of disk space. Minimum of 2 GB of RAM.
Tip If you want to try the SQL Server 2019 preview image, see the. The previous command pulls the latest SQL Server 2017 container image. If you want to pull a specific image, you add a colon and the tag name (for example, mcr.microsoft.com/mssql/server:2017-GA-ubuntu). To see all available images, see. For the bash commands in this article, sudo is used. On MacOS, sudo might not be required. On Linux, if you do not want to use sudo to run Docker, you can configure a docker group and add users to that group.
For more information, see. To run the container image with Docker, you can use the following command from a bash shell (Linux/macOS) or elevated PowerShell command prompt.
Sudo docker run -e 'ACCEPTEULA=Y' -e 'SAPASSWORD=' -p 1433:1433 -name sql1 -d mcr.microsoft.com/mssql/server:2017-latest docker run -e 'ACCEPTEULA=Y' -e 'SAPASSWORD=' ` -p 1433:1433 -name sql1 ` -d mcr.microsoft.com/mssql/server:2017-latest. Note By default, this creates a container with the Developer edition of SQL Server 2017. The process for running production editions in containers is slightly different.
For more information, see. The following table provides a description of the parameters in the previous docker run example: Parameter Description -e 'ACCEPTEULA=Y' Set the ACCEPTEULA variable to any value to confirm your acceptance of the.

Mcr.microsoft.com/mssql/server:2017-latest The SQL Server 2017 Linux container image. To view your Docker containers, use the docker ps command. Sudo docker ps -a docker ps -a You should see output similar to the following screenshot:. If the STATUS column shows a status of Up, then SQL Server is running in the container and listening on the port specified in the PORTS column. If the STATUS column for your SQL Server container shows Exited, see the. The -h (host name) parameter is also useful, but it is not used in this tutorial for simplicity.
This changes the internal name of the container to a custom value. This is the name you'll see returned in the following Transact-SQL query: SELECT @@SERVERNAME, SERVERPROPERTY('ComputerNamePhysicalNetBIOS'), SERVERPROPERTY('MachineName'), SERVERPROPERTY('ServerName') Setting -h and -name to the same value is a good way to easily identify the target container.
Tip This quickstart uses the SQL Server 2019 preview Docker image. If you want to run the SQL Server 2017 image, see the. The previous command pulls the latest SQL Server 2019 preview container image based on Ubuntu. To instead use container images based on RedHat, see.

Change the SA password The SA account is a system administrator on the SQL Server instance that gets created during setup. After creating your SQL Server container, the MSSQLSAPASSWORD environment variable you specified is discoverable by running echo $MSSQLSAPASSWORD in the container. For security purposes, change your SA password. Choose a strong password to use for the SA user. Use docker exec to run sqlcmd to change the password using Transact-SQL.
Replace and with your own password values. Sudo docker exec -it sql1 /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P ' -Q 'ALTER LOGIN SA WITH PASSWORD=' docker exec -it sql1 /opt/mssql-tools/bin/sqlcmd ` -S localhost -U SA -P ' ` -Q 'ALTER LOGIN SA WITH PASSWORD=' Connect to SQL Server The following steps use the SQL Server command-line tool, sqlcmd, inside the container to connect to SQL Server. 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. Sudo docker exec -it sql1 'bash' docker exec -it sql1 'bash'. Once inside the container, connect locally with sqlcmd. Sqlcmd is not in the path by default, so you have to specify the full path.

/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P '. Tip You can omit the password on the command-line to be prompted to enter it. If successful, you should get to a sqlcmd command prompt: 1. Create and query data The following sections walk you through using sqlcmd and Transact-SQL to create a new database, add data, and run a simple query. Create a new database The following steps create a new database named TestDB. From the sqlcmd command prompt, paste the following Transact-SQL command to create a test database: CREATE DATABASE TestDB. On the next line, write a query to return the name of all of the databases on your server: SELECT Name from sys.Databases.
The previous two commands were not executed immediately. You must type GO on a new line to execute the previous commands: GO Insert data Next create a new table, Inventory, and insert two new rows. From the sqlcmd command prompt, switch context to the new TestDB database: USE TestDB.
Create new table named Inventory: CREATE TABLE Inventory (id INT, name NVARCHAR(50), quantity INT). Insert data into the new table: INSERT INTO Inventory VALUES (1, 'banana', 150); INSERT INTO Inventory VALUES (2, 'orange', 154);. Type GO to execute the previous commands: GO Select data Now, run a query to return data from the Inventory table.
From the sqlcmd command prompt, enter a query that returns rows from the Inventory table where the quantity is greater than 152: SELECT. FROM Inventory WHERE quantity 152;. Execute the command: GO Exit the sqlcmd command prompt. To end your sqlcmd session, type QUIT: QUIT. To exit the interactive command-prompt in your container, type exit.
Your container continues to run after you exit the interactive bash shell. Connect from outside the container You can also connect to the SQL Server instance on your Docker machine from any external Linux, Windows, or macOS tool that supports SQL connections.
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 principals 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.
Run sqlcmd specifying the IP address and the port mapped to port 1433 in your container. In this example, that is the same port, 1433, on the host machine. If you specified a different mapped port on the host machine, you would use it here. Sqlcmd -S 10.3.2.4,1433 -U SA -P ' sqlcmd -S 10.3.2.4,1433 -U SA -P '.
Run Transact-SQL commands. When finished, type QUIT. Other common tools to connect to SQL Server include:.
Remove your container If you want to remove the SQL Server container used in this tutorial, run the following commands: sudo docker stop sql1 sudo docker rm sql1 docker stop sql1 docker rm sql1.
