Kubernetes in Practice is your one-stop shop for learning how to build, deploy, scale, and manage Kubernetes in a step-by-step process.

You will learn all the most important concepts including: architecture, pods, deployments, services, ingress, and a whole lot more. Once you have the fundamentals out of the way, you will get the opportunity to put your skills to work in a project where you will create and run an application in a real Kubernetes cluster.

By the time you finish this course, you will have complete confidence when it comes to deploying and managing kubernetes clusters.

Kubernetes in Practice

It's common to need to pass sensitive configs to our applications like credentials and private keys. We could use `ConfigMaps` for these configs as well, but when we are concerned with the security of these values, we have a better option: `Secrets`.

The way a `Secret` is used is pretty similar to a `ConfigMap`, but there are some key differences in how they work under the hood:

* `Secrets` are only distributed to the nodes that are running a pod that needs them.
* They are never written to physical storage.
* In the master node, they are stored encrypted.
* When we read a `Secret`, we will get the data `base64` encoded. This is mostly so we can store binary values in a secret, not much of a security feature as `base64` is easily decoded.

So with that in mind, let's see how a `Secret`  is created and used.
