I've made the decision to investigate and experiment with the docker. I therefore considered learning and imparting knowledge to others while I was doing it. Thus, I installed Docker on Windows 11 and used it to run the MS SQL server in this article.

Requirements
A laptop with at least 8 GB of RAM
Set up the docker
MS SQL Server Management Studio
After successfully installing the docker you need to sign into the Docker Hub. https://hub.docker.com/
Before you move to the next step, you need to learn some basics about Docker & the norms and nuances used in it.

What is Docker?
"Docker is an open platform for developing, shipping, and running applications," according to the Docker documentation. Docker allows you to rapidly release software by separating your apps from your infrastructure. You can use Docker to manage your infrastructure in the same manner that you do your apps. You may cut down on the amount of time it takes between writing code and having it run in production by utilizing Docker's shipping, testing, and deployment processes."

We can run the applications without caring about the underlying environment thanks to Docker. Since we can use that in the Docker application, we'll include all dependencies and necessary files in the container.

You've been curious about what a container is
Code can be executed in an isolated environment using a container. In other words, the container operates in the context where Docker Desktop is available, without any knowledge of the underlying operating system or files.

Docker Hub
It's a registry for Docker images hosted in the cloud. Users may share, search, and control Docker images with it. For developers wishing to create and launch apps using Docker, Docker Hub is a well-liked option.

Ok, done with our theory. Let's dive into the hands-on.

How to Run MS SQL Server on Docker
We need to find the MSSQL Server image that runs on the Ubuntu. https://hub.docker.com/_/microsoft-mssql-server

As I previously stated, the MSSQL Server is operating on Ubuntu, but my base environment is Windows 11. The photograph is available at the aforementioned URL. The command on the page to the command prompt must be used.

docker pull mcr.microsoft.com/mssql/server:2022-latest

You'll face the error when the Docker Deamon is not running.

Otherwise, it'll look like this.

Use the command, to show the images available
docker images

You can also see the same image on the Docker Desktop too.

Now, you need to install the MSSQL Image on the Docker using the below command
docker run -e "ACCEPT_EULA=Y" -e "MSSQL_SA_PASSWORD=<StrongPassword>" -p 1433:1433 --name sql1 --hostname sql1 -d  mcr.microsoft.com/mssql/server:2022-latest

You need to set the ACCEPT_EULA variable to Y to accept the end user license agreement and the SA_PASSWORD variable to a strong password for the system administrator account. After the successful login, you can able to see the container running in the Docker Desktop

You must launch the MS SQL Server Management Studio and fill in the fields displayed in the screenshot in order to access the SQL Server.

Both the password and the username, SA, must be entered. Once your authentication has been successful, you can query the system databases.

That's all I have for now; in the next post, I'll demonstrate how to link this database to the.NET applications. Please let me know if you have any problems completing the aforementioned tasks.

Tracking down problems in SQL Server entails diagnosing and resolving issues at their core. These are some general actions that you can take.
Examine the error logs.

SQL Server keeps error logs, which are a useful source of information concerning problems. Look for any error messages in the Windows Event Viewer and the SQL Server Error Log.

Open SQL Server Management Studio (SSMS).

• Link to the instance of SQL Server.
• In the Object Explorer, expand "Management".
• Select "View SQL Server Log" with a right-click on "SQL Server Logs."
• Check for any warnings or error messages.

Event Viewer for Windows

• Check the Windows Event Viewer for system and application logs.
• Keep an eye out for any occurrences connected to database or SQL Server problems.

Make use of SQL Server Management Studio (SSMS)
To check for defects or performance problems, use SSMS to connect to the SQL Server instance and run queries. Look for any error warnings in the output.

• Query Execution Plans: Use the "Execution Plan" feature in SSMS to analyze the execution plan of a query. This can help identify performance bottlenecks and suggest improvements.
• Profiler Traces: SQL Server Profiler allows you to capture and analyze events as they occur in real-time. Tracing can help identify slow queries or other issues.

Dynamic Management Views (DMVs) and Dynamic Management Functions (DMFs)
A collection of DMVs and DMFs offered by SQL Server provide information about resource utilization, server performance, and other metrics. Sys.dm_exec_sessions, sys.dm_exec_requests, and sys.dm_os_wait_stats are a few examples.

Check Disk Space
Transaction failures or problems with performance can result from insufficient disk space. Make sure the drives holding SQL Server's data, log files, and backups have adequate room.

Review SQL Server Configuration
Check that the setup parameters for the server and database are in line with industry best practices. Keep an eye on memory, parallelism, and other performance-related configuration parameters.

Indexing
Index omissions or poor design might affect query performance. To find missing indexes, examine execution plans or use the Database Engine Tuning Advisor.

Monitor Blocking and Deadlocks
Use tools like SQL Server Profiler, Extended Events, or queries against system views (sys.dm_tran_locks, sys.dm_os_waiting_tasks) to discover and fix blocking and deadlock issues.

Review Application Code
There are instances when the application code may be the problem. Make that the SQL queries running are optimized by reviewing them. Aim for parameterization and steer clear of pointless database round trips.

Security Auditing
Ensure that security policies are correctly implemented and that there are no unauthorized accesses or security vulnerabilities.

Regular Maintenance
Carry out routine database maintenance, including statistics updates, index rebuilds, and consistency checks.

Keep in mind that the precise steps you take to identify problems may change based on the type of situation you are dealing with. It frequently involves looking into logs, examining query results, and figuring out how well the system is functioning as a whole.
