Context

Anytime a team needs to run a container on Kubernetes they will need to define a pod within which to run the container.

Task

Please complete the following:

• Create a YAML formatted pod manifest

/opt/KDPD00101/podl.yml to create a pod named app1 that runs a container named app1cont using image Ifccncf/arg-output

with these command line arguments: -lines 56 -F

• Create the pod with the kubect1 command using the YAML file created in the previous step

• When the pod is running display summary data about the pod in JSON format using the kubect1 command and redirect the output to a file named /opt/KDPD00101/out1.json

• All of the files you need to work with have been created, empty, for your convenience

Task:

Update the Deployment app-1 in the frontend namespace to use the existing ServiceAccount app.

Task:

Update the Pod ckad00018-newpod in the ckad00018 namespace to use a NetworkPolicy allowing the Pod to send and receive traffic only to and from the pods web and db

Task

A Deployment named backend-deployment in namespace staging runs a web application on port 8081.

Set Configuration Context:

[student@node-1] $ | kubectl

Config use-context k8s

Context

A pod is running on the cluster but it is not responding.

Task

The desired behavior is to have Kubemetes restart the pod when an endpoint returns an HTTP 500 on the /healthz endpoint. The service, probe-pod, should never send traffic to the pod while it is failing. Please complete the following:

• The application has an endpoint, /started, that will indicate if it can accept traffic by returning an HTTP 200. If the endpoint returns an HTTP 500, the application has not yet finished initialization.

• The application has another endpoint /healthz that will indicate if the application is still working as expected by returning an HTTP 200. If the endpoint returns an HTTP 500 the application is no longer responsive.

• Configure the probe-pod pod provided to use these endpoints

• The probes should use port 8080

Task

Create a new deployment for running.nginx with the following parameters;

• Run the deployment in the kdpd00201 namespace. The namespace has already been created

• Name the deployment frontend and configure with 4 replicas

• Configure the pod with a container image of lfccncf/nginx:1.13.7

• Set an environment variable of NGINX__PORT=8080 and also expose that port for the container above

Context

It is always useful to look at the resources your applications are consuming in a cluster.

Task

• From the pods running in namespace cpu-stress , write the name only of the pod that is consuming the most CPU to file /opt/KDOBG030l/pod.txt, which has already been created.

Task:

Modify the existing Deployment named broker-deployment running in namespace quetzal so that its containers.

1) Run with user ID 30000 and

2) Privilege escalation is forbidden

The broker-deployment is manifest file can be found at:

Task:

Create a Pod named nginx resources in the existing pod resources namespace.

Specify a single container using nginx:stable image.

Specify a resource request of 300m cpus and 1G1 of memory for the Pod’s container.
