Task Summary
* SSH into the correct node: cka000037
* Modify existing deployment synergy-leverager
* Add a sidecar container:
* Name: sidecar
* Image: busybox:stable
* Command:
/bin/sh -c "tail -n+1 -f /var/log/synergy-leverager.log"
* Use a shared volume mounted at /var/log
* Don't touch existing container config except adding volume mount
Step-by-Step Solution
1## SSH into the correct node
ssh cka000037
## Skipping this will result in a zero score.
2## Edit the deployment
kubectl edit deployment synergy-leverager
This opens the deployment YAML in your default editor (vi or similar).
3## Modify the spec as follows
# Inside the spec.template.spec, do these 3 things:
# A. Define a shared volume
Add under volumes: (at the same level as containers):
volumes:
- name: log-volume
emptyDir: {}
# B. Add volume mount to the existing container
Locate the existing container under containers: and add this:
volumeMounts:
- name: log-volume
mountPath: /var/log
# Do not change any other configuration for this container.
# C. Add the sidecar container
Still inside containers:, add the new container definition after the first one:
- name: sidecar
image: busybox:stable
command:
- /bin/sh
- -c
- "tail -n+1 -f /var/log/synergy-leverager.log"
volumeMounts:
- name: log-volume
mountPath: /var/log
spec:
containers:
- name: main-container
image: your-existing-image
volumeMounts:
- name: log-volume
mountPath: /var/log
- name: sidecar
image: busybox:stable
command:
- /bin/sh
- -c
- "tail -n+1 -f /var/log/synergy-leverager.log"
volumeMounts:
- name: log-volume
mountPath: /var/log
volumes:
- name: log-volume
emptyDir: {}
Save and exit
If using vi or vim, type:
bash
CopyEdit
wq
5## Verify
Check the updated pods:
kubectl get pods -l app=synergy-leverager
Pick a pod name and describe it:
kubectl describe pod <pod-name>
Confirm:
* 2 containers running (main-container + sidecar)
* Volume mounted at /var/log
ssh cka000037
kubectl edit deployment synergy-leverager
# Modify as explained above
kubectl get pods -l app=synergy-leverager
kubectl describe pod <pod-name>

Task Summary
* SSH into cka000060
* Add the Argo CD Helm repo named argo
* Generate a manifest (~/argo-helm.yaml) for Argo CD version 7.7.3
* Target namespace: argocd
* Do not install CRDs
* Just generate, don't install
# Step-by-Step Solution
1## SSH into the correct host
ssh cka000060
## Required - skipping this = zero score
2## Add the Argo CD Helm repository
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
# This adds the official Argo Helm chart source.
3## Generate Argo CD Helm chart template (version 7.7.3)
Use the helm template command to generate a manifest and write it to ~/argo-helm.yaml.
helm template argocd argo/argo-cd \
--version 7.7.3 \
--namespace argocd \
--set crds.install=false \
> ~/argo-helm.yaml
* argocd # Release name (can be anything; here it's same as the namespace)
* --set crds.install=false # Disables CRD installation
* > ~/argo-helm.yaml # Save to required file
# 4## Verify the generated file (optional but smart)
head ~/argo-helm.yaml
Check that it contains valid Kubernetes YAML and does not include CRDs.
# Final Command Summary
ssh cka000060
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
helm template argocd argo/argo-cd \
--version 7.7.3 \
--namespace argocd \
--set crds.install=false \
> ~/argo-helm.yaml
head ~/argo-helm.yaml # Optional verification
