/C=US/ST=NV/L=Hiko/O=CIA/OU=USAF/CN=classified.apps.domainxx.example.com The application is reachable only at the following address: https://classified.apps.domainxx.example.com The application produces output A utility script called newcert has been provided to create the CA signed certificate. You may enter the certificate parameters manually or pass the subject as a parameter.
Your certificate signing request will be uploaded to the CA where it will immediately be signed and then downloaded to your current directory.
正解：
解説：
See the solution below in Explanation.
Explanation:
Solution:
$ oc project area51
$ oc get pods
$ oc get all | grep deployment
$ oc get route
$ oc delete route oxcart
$ openssl genrsa -out ex280.key 2048
$ openssl req -new -key ex280.key -out ex280.csr -subj "/C=US/ST=NV/L=Hiko/O=CIA/OU=USAF
/CN=classified.apps.domainxx.example.com"
$ openssl x509 -req -in ex280.csr -signkey ex280.key -out ex280.crt
$ oc create route edge oxcart --service oxcart --key ex280.key --cert ex280.crt --hostname classified.apps.
domainxx.example.com
$ oc get route
$ oc get svc
質問 # 12
Configure limits
Configure your OpenShift cluster to use limits in the bluebook project with the following requirements:
The name of the LimitRange resource is: ex280-limits
The amount of memory consumed by a single pod is between 5Mi and 300Mi The amount of memory consumed by a single container is between 5Mi and
300Mi with a default request value of 100Mi
The amount of CPU consumed by a single pod is between 10m and 500m
The amount of CPU consumed by a single container is between 10m and 500m with a default request value of
100m
正解：
解説：
See the solution below in Explanation.
Explanation:
Solution:
$ vim limit.yaml
# Edit the yaml file like below mentioned
apiVersion: "v1" kind: "LimitRange" metadata:
name: "resource-limits" spec:
limits:
- type: "Pod"
max:
cpu: "500m" memory: "300Mi"
min:
cpu: "10m" memory: "5Mi"
- type: "Container" max:
cpu: "500m" memory: "300Mi"
min:
cpu: "10m" memory: "5Mi"
defaultRequest: cpu: "100m" memory: "100Mi"
$ oc create -f limit.yaml --save-config -n bluebook
$ oc describe limitranges -n bluebook
質問 # 13
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.
正解：
解説：
See the solution below in Explanation.
Explanation:
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.

正解：
解説：
See the solution below in Explanation.
Explanation:
Solution:
$ oc adm groups new commander
$ oc adm groups new pilot
$ oc adm groups add-users commander armstrong
$ oc adm groups add-users pilot collins
$ oc adm groups add-users pilot aldrin
$ oc adm policy add-role-to-group edit commander -n apollo
$ oc adm policy add-role-to-group view pilot -n apollo

Prevent ordinary authenticated users from self-provisioning projects.
Allow john to create projects.
Give natasha view-only access to test and apollo .
Give armstrong admin access to apollo .
Remove the kubeadmin user secret.
正解：
解説：
See the solution below in Explanation.
Explanation:
Solution:
* Create the projects:
oc new-project apollo
oc new-project test
oc new-project demo

* Disable normal self-provisioning for authenticated users:
oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauth
* Allow john to self-provision:
oc adm policy add-cluster-role-to-user self-provisioner john
* Give natasha view access in test and apollo:
oc policy add-role-to-user view natasha -n test
oc policy add-role-to-user view natasha -n apollo
* Give armstrong admin in apollo:
oc policy add-role-to-user admin armstrong -n apollo
* Remove kubeadmin secret:
oc delete secret kubeadmin -n kube-system
* Verify permissions:
