Kubernetes is a powerful tool. It can help you manage complex applications and provide you with the ability to easily automate tasks involved in managing them. In this course, we will start exploring Kubernetes from a beginner's standpoint. We will discuss what Kubernetes is and what it does, and we will work with some of the basic functionality of Kubernetes hands-on. We will build a simple Kubernetes cluster. We will also deploy a sample microservice application to the cluster in order to explore how Kubernetes can help easily manage such applications.

A Practical Guide to Kubernetes

# Creating Secrets
The commands to create Secrets are almost the same as those we used to create ConfigMaps. We can, for example, generate Secrets based on literal values.

kubectl create secret \
    generic my-creds \
    --from-literal=username=jdoe \
    --from-literal=password=incognito


>The major difference is that we specified the type of the Secret as `generic`. 

It could also be `docker-registry` or `tls`. We won't explore those two, but only say that the former can be used to provide `kubelet` with credentials it needs to pull images from private registries. The latter is used for storing certificates. 

In this chapter, we'll focus on the `generic` type of secrets which happen to use the same syntax as ConfigMaps.

Just as with ConfigMaps, generic Secrets can use `--from-env-file`, `--from-file`, and `--from-literal` as sources. They can be mounted as files, or transformed into environment variables. Since creating Secrets is so similar to creating ConfigMaps, we won't go into all the permutations we can do. 

For now, we created a Secret called `my-creds` which holds two literal values.
# Working with Secrets
Let's take a look at the Secrets we now have in the cluster.

In this lesson, we will create generic Secrets.
