Refresher on ways to manage Kubernetes pods
I'll keep this brief -- here's a reminder on the various ways that Kubernetes can manage pods:
- Kubernetes Deployment - The most common way to deploy containerized applications. This approach lets you control the number of replicas running. When you have a new version of the application running, Kubernetes can keep the . . .
Kubernetes Worker Node Architecture 101
Here's some quick recap points regarding worker nodes in Kubernetes:
- Remember the previous analogy about the Kubernetes control plane being like an air traffic control tower? Think of a worker node as an airport terminal where planes park and passengers board.
- In order to be highly available, most Kubernetes clusters . . .
Kubernetes Control Plane Architecture 101
Here's a quick recap of kubernetes control plane architecture:
- An instance of Kubernetes is called a cluster.
- Each cluster has a control plane and at least one worker node.
- Think of the control plane like air traffic control at a busy airport with people overlooking the cluster to make sure nodes and pods are . . .

That's because high up in the sshd_config file, there's a statement to include additional configs:

Because sometimes it's nice to have terminology all in one place.
Here's a list of terms and concepts I get asked about. I'll keep adding to it over time.
Containers / Kubernetes
- Containers -- A technology that bundles the code for an application, and the configuration required to run the code itself, in one unit. (Source: LinkedIn Learning)

Image vs Container Registry
I like analogies. They make it easier to express ideas and communicate concepts.
Recently someone was asking about the difference between an "images" vs "registry", and how they pertain to containers.
I came across this one amidst a google search (source unknown - sorry):
