Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

# Creating a Pod with Mongo

Just as we can execute `docker run` to create containers, `kubectl` allows us to create Pods with a **single command**. 
For example, if we'd like to create a Pod with a *Mongo database*, the command is as follows:



You'll notice that the output says that "pod/db created". We have created our first Pod. We can confirm that by listing all the Pods in the cluster. 


The **output** should be something like this:

NAME   READY   STATUS              RESTARTS  AGE
db     0/1     ContainerCreating   0         1m

In the **output**, we can see the following: 
* The name of the Pod 
* Its readiness 
* Its the status
* The number of times it has restarted 
* For how long it has existed (its age) 

If your network is slow, none of the Pods might be ready. We expect to have **one** Pod, but there's **zero** running at the moment.

Since the `mongo` image is relatively big, it might take a while until it is pulled from *Docker Hub*. After a while, we can retrieve the Pods one more time to confirm that the Pod with the Mongo database is indeed running. The **output** this time is as follows:
