Kubernetes: Basic Redis Deployment

QUESTION DESCRIPTION

A company wants to deploy a web application has built on Kubernetes.  As part of that process, complete a file stub "/home/ubuntu/1091251-kubernetes-basic-redis-deployment/definition.yml" with one or more steps that do the following:

• Creates a new namespace "hacker-company".
• Deploys a new "redis" image (from Dockerhub) on the "buster" tag as "redis" deployment, in the "hacker-company" namespace.
• Increases the pods number of the "redis" deployment up to 2 replicas.
• Exposes "6379" port of the "redis" containers.

Note

• The completed solution will be evaluated in a new, clean environment. Be sure everything is in the "/home/ubuntu/1091251-kubernetes-basic-redis-deployment" folder.
• All the tasks should be done within a simple "sudo solve" execution invoked from the question directory.
• You have sudo access.

Grading

• The execution result of "sudo solve" invoked from the question directory solves the task.
