Step 1: Identify the namespace of the pod foo  \nFirst, check if foo is running in a specific namespace or in the default namespace. kubectl get pods--all-namespaces | grep foo  \nAssume the pod is in the default namespace if no namespace is mentioned.  \nStep 2: Confirm pod foo exists and is running kubectl get pod foo  \nYou should get output similar to:  \nNAME READY STATUS RESTARTSAGE  \nfoo 1/1 Running 0 1h  \nIf the pod is not running, logs may not be available.  \nStep 3: View logs and filter specific error lines We’re looking for log lines that contain:  \nunable-to-access-website Command:  \nkubectl logs foo | grep \"unable-to-access-website\"Step 4: Write the filtered log lines to a file Redirect the output to the required path:  \nkubectl logs foo | grep \"unable-to-access-website\" > /opt/KULM00201/foo  \n This creates or overwrites the file /opt/KULM00201/foo with the filtered logs.  \nYou may need sudo if /opt requires elevated permissions. But in most exam environments, you're already the root or privileged user.  \nStep 5: Verify the output file (optional but smart)  \nCheck that the file was created and has the correct content: cat /opt/KULM00201/foo  \n Final Answer Summary: kubectl config use-context k8s  \nkubectl logs foo | grep \"unable-to-access-website\" > /opt/KULM00201/foo  \n2.SIMULATION  \nList all persistent volumes sorted by capacity, saving the full kubectl output to  \n/opt/KUCC00102/volume_list. Use kubectl 's own functionality for sorting the output, and do not manipulate it any further.  \nAnswer:  \nsolution  \n3.SIMULATION  \nEnsure a single instance of pod nginx is running on each node of the Kubernetes cluster where nginx also represents the Image name which has to be used. Do not override any taints currently in place. Use DaemonSet to complete this task and use ds-kusc00201 as DaemonSet name.  \nAnswer:  \nsolution  \n4.SIMULATION  \nPerform the following tasks:  \nAdd an init container to hungry-bear (which has been defined in spec file /opt/KUCC00108/pod-spec-  \nKUCC00108.yaml)  \nThe init container should create an empty file named/workdir/calm.txt If /workdir/calm.txt is not detected, the pod should exit  \nOnce the spec file has been updated with the init container definition, the pod should be created  \nAnswer:  \nsolution  \n5.SIMULATION  \nCreate a pod named kucc8 with a single app container for each of the following images running inside (there may be between 1 and 4 images specified):  \nnginx + redis + memcached.  \nAnswer:  \nsolution","cbCaioIahpTk3gwY","https://ap.wps.com/l/cbCaioIahpTk3gwY","pdf",1050882,11,"English","# Simulation 1 - Pod logs filtering\n## Set context, find namespace, confirm pod, filter errors, write to file\n# Simulation 2 - Persistent volumes by capacity\n## Save full kubectl output to required path\n# Simulation 3 - DaemonSet for one pod per node\n## Use DaemonSet name ds-kusc00201 without overriding taints\n# Simulation 4 - Init container file creation and pod exit\n## Update pod spec and create /workdir/calm.txt\n# Simulation 5 - Create pod kucc8 with specified images\n## One app container per image (nginx, redis, memcached)","[{\"question\":\"How do you switch to the correct Kubernetes context before troubleshooting a pod?\",\"answer\":\"Use kubectl config use-context k8s when a specific context is provided, to avoid working in the wrong cluster or namespace.\"},{\"question\":\"What steps are used to extract log lines containing unable-to-access-website and save them to a file?\",\"answer\":\"Identify the pod’s namespace, confirm the pod exists and is running, then run kubectl logs foo | grep \\\"unable-to-access-website\\\" and redirect the filtered output to /opt/KULM00201/foo.\"},{\"question\":\"How can you ensure a single nginx pod runs on each node without changing existing taints?\",\"answer\":\"Create a DaemonSet with the name ds-kusc00201 to schedule one pod per node, and do not override any currently configured taints.\"}]","Certified Kubernetes Administrator - DEMO - Simulation 1-5 | PDF",28]
