Kubernetes Administrator: Managing Pods & Deployments

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. Kubernetes uses pods to wrap up one or more containers. The primary objective of deployments is to declare the number of replicas of a pod that should be running at a time and also ensure the pods' availability by recreating them when they are not available. In this course, you'll learn to perform critical pod and deployment tasks, which includes creating a ReplicaSet definition file, using kubectl commands to create a ReplicaSet, verifying management of pods by specific ReplicaSets, removing ReplicaSet-managed pods, and increasing the number of pods when the CPU load gets higher without exceeding five pods. Next, you’ll create a deployment definition file and use the kubectl command to deploy four pods with NGINX. You'll also use the kubectl scale command to scale replicas, create a Kubernetes user account using the X509 client certificate, schedule and launch pods, and taint a node. Moving on, you’ll create a manifest file that creates a pod with a sample container, manually schedule a pod and force a pod to be on a specific node, and use kubectl commands to create a pod and configure environment variables. Finally, you’ll create a secret from files containing a username and password, define environment variables, and mount the secret to a pod. This course is part of a series that aligns with the objectives for the Certified Kubernetes Administrator exam and can be used to prepare for this exam.
