Task 10
Create Secure Route in Quart Project
Task information Details:
Create an edge route named htquart for service httpd, using the specified hostname and TLS certificate/key files.
Solution:
Switch to the quart project:
oc project quart
Create the secure route:
oc create route edge htquart \
--service=httpd \
--hostname=quart.apps.ocp4.example.com \
--cert=./req.crt \
--key=./req.key
Verify:
oc get route htquart
oc describe route htquart
Test resolution and access if DNS is available:
curl -k https://quart.apps.ocp4.example.com
This task checks route exposure, TLS termination, and secure ingress administration.
SIMULATION
Task 11
Create Service Account in QED
Task information Details:
Switch to project qed.
Create service account project1-sa.
Grant the anyuid SCC to that service account.
Solution:
Switch to the project:
oc project qed
Create the service account:
oc create serviceaccount project1-sa -n qed
Grant the SCC:
oc adm policy add-scc-to-user anyuid -z project1-sa -n qed
Verify:
oc get sa project1-sa -n qed
oc adm policy who-can use scc anyuid
Why this matters:
anyuid allows containers to run with arbitrary user IDs when an application requires it.
This is a common administrative task in OpenShift for third-party container images.
This task validates service account creation and SCC assignment.
SIMULATION
Task 1
Manage Identity Provider
Task information Details:
Create the following HTPasswd users: bob, qwerty, john, armstrong, natasha, harry, susan.
Create a secret from the HTPasswd file in openshift-config.
Configure cluster OAuth to use the HTPasswd identity provider.
Restart the OAuth pods so the new authentication configuration takes effect.
Solution:
Create the initial HTPasswd file with the first user:
htpasswd -c -B -b /tmp/htpass.txt bob indionce
Add the remaining users:
htpasswd -b /tmp/htpass.txt qwerty catalog
htpasswd -b /tmp/htpass.txt john john123
htpasswd -b /tmp/htpass.txt armstrong natasha123
htpasswd -b /tmp/htpass.txt natasha arthstrong
htpasswd -b /tmp/htpass.txt harry harry123
htpasswd -b /tmp/htpass.txt susan susuan123
Create the secret in openshift-config:
oc create secret generic ex280-secure --from-file=htpasswd=/tmp/htpass.txt -n openshift-config
Edit OAuth and add the HTPasswd identity provider:
oc edit oauth cluster
Use a valid structure like this:
spec:
identityProviders:
- name: ex280-idp-secure
mappingMethod: claim
type: HTPasswd
htpasswd:
fileData:
name: ex280-secure
Save and exit.
Restart OAuth pods:
oc delete pod -n openshift-authentication -l app=oauth-openshift
Verify:
oc get pods -n openshift-authentication
oc get oauth cluster -o yaml
This task validates OpenShift local authentication configuration through HTPasswd and cluster OAuth integration.
SIMULATION
Task 8
Create Secret with Name Magic in Math Project
Task information Details:
Create a secret named magic in the math project that stores MYSQL_ROOT_PASSWORD=redhat.
Solution:
Switch to the math project:
oc project math
Create the secret:
oc create secret generic magic --from-literal=MYSQL_ROOT_PASSWORD=redhat
Verify:
oc get secret magic
oc describe secret magic
Note:
The uploaded lab text contains a typo --from-listeral; the valid option is --from-literal.
The output in the lab also appears inconsistent. The intended secret name is magic.
This task checks secret creation and secure configuration data handling.
SIMULATION
Task 5
Create LimitRanges for Project Darpa
Task information Details:
Switch to project darpa and create a LimitRange with Pod and Container minimums and maximums of CPU and memory, plus default container values.
Solution:
Switch to the target project:
oc project darpa
Create a YAML file, for example limitrange.yaml:
apiVersion: v1
kind: LimitRange
metadata:
name: darpa-limits
namespace: darpa
spec:
limits:
- type: Pod
max:
cpu: 300m
memory: 300Mi
min:
cpu: 5m
memory: 5Mi
- type: Container
max:
cpu: 300m
memory: 300Mi
min:
cpu: 5m
memory: 5Mi
default:
cpu: 100m
memory: 100Mi
Apply it:
oc apply -f limitrange.yaml
Verify:
oc get limitrange -n darpa
oc describe limitrange darpa-limits -n darpa
This task validates namespace-level defaulting and constraint policies for pod scheduling and resource consumption.
