In Kubernetes we can leverage Controllers to help manage our application state, keeping them in the desired state. In this blog post, we’re going to look at how to use a Deployment Controller to manage the application state of SQL Server in Kubernetes. We’ll look at deploying SQL Server in a Deployment and using that deployment to upgrade SQL Server and rollback our upgrade. Deploying SQL Server in a Deployment Let’s start off with deploying SQL Server in Kubernetes.

I’m proud to announce that I will be speaking at this months We Speak Linux Webinar. Each month We Speak Linux brings cross platform training to the Windows world. Sign up now here! On Thursday, December 2 at 11:00 Central I’m presenting: OpenSSH for Windows Pros Here’s the abstract: In PowerShell Core we can use OpenSSH as the transport layer to carry our remoting sessions between our systems. In this session we’ll look at OpenSSH architecture, Authentication methods, including key authentication, sshd configuration, and troubleshooting methods when things go wrong!

Ever want to confirm that a port is accessible from one computer to another? There’s a PowerShell cmdlet for that, Test-NetConnection. With the -Port option, this cmdlet will do a quick TCP three-way handshake on the remote system to confirm that the service is available and reports back if it succeeded or not. Check out that last line of output TcpTestSucceeded: False. That indicates that this port is not accessible. You can see, however, that the system is reachable via ICMP (Ping), PingSuceeded: True so we know that the remote system is alive, just not listening on the port we want to access.

Here’s a run down of the Linux training that I have available on Pluralsight! Just getting started! Understanding and Using Essential Tools for Enterprise Linux 7 – If you heard what Linux is and want to get started this is the place to be. We’ll cover installation, command line basics, the file system, text editors and more! This is my most popular course. SQL Server on Linux Administration Fundamentals – SQL Server is available for Linux and Docker!

In this blog post we’re going to revisit how SQL Server on Linux responds to external memory pressure. This is a very long post, and it ends with me not knowing exactly what’s going on…but the journey is pretty fun…let’s go! On Windows-based SQL Server systems we’ve become accustomed to the OS signaling to SQL Server that there’s a memory shortage. When signaled, SQL Server will kindly start shrinking it’s memory caches, including the buffer pool, to maintain overall system stability and usability.
