Kubernetes Daily Challenge: Day 42 Question: -------- In the dev-wl07 namespace, one of the developers has performed a rolling update and upgraded the application to a newer version. But somehow, application pods are not being created. To get back the working state, rollback the application to the previous version . After rolling the deployment back, on the controlplane node, save the image currently in use to the /root/rolling-back-record.txt file and increase the replica count to the 5. You can SSH into the cluster1 using ssh cluster1-controlplane command. Answer:  ------ Run the command to change the context: - kubectl config use-context cluster1 Check the status of the pod: - kubectl get pods -n dev-wl07 One of the pods is in an error state. As a quick fix, we need to rollback to the previous revision as follows: - kubectl rollout undo -n dev-wl07 deploy webapp-wl07 After successful rolling back, inspect the updated image: - kubectl describe deploy -n dev-wl07 webapp-wl07 | grep -i image On the Controlplane node, save the image name to the given path /root/rolling-back-record.txt: - ssh cluster1-controlplane echo "kodekloud/webapp-color" > /root/rolling-back-record.txt And increase the replica count to the 5 with help of kubectl scale command: - kubectl scale deploy -n dev-wl07 webapp-wl07 --replicas=5 Verify it by running the command: kubectl get deploy -n dev-wl07 --------Done------- Feel free to comment on queries related to Kubernetes CKA.

Excited to share a project milestone! 🚀 A while ago, I took on the challenge of building a robust CI/CD pipeline using the powerful trio of ArgoCD, Jenkins, and deploying it seamlessly into an EKS cluster. 🛠️💻 The journey was filled with learning and growth, and I'm thrilled to showcase the results. 🌐✨ 🔍 What went into it? ArgoCD: Orchestrating GitOps for continuous deployment. Jenkins: Automating the build and deployment process. EKS Cluster: A scalable and reliable environment for hosting the application. 💡 Why this combination? ArgoCD's declarative approach for GitOps simplifies continuous delivery. Jenkins' versatility in automating complex workflows. EKS provides a managed Kubernetes environment for secure and efficient container orchestration. 🎉 What did we achieve? Streamlined development-to-production workflow. Increased deployment speed and reliability. Enhanced collaboration and version control. 🙌 Gratitude: Huge shoutout to Abhishek Veeramalla being part of vibrant tech community and sharing valuable insights and support throughout this journey.

Kubernetes Daily Challenge: Day 41 Question: -------- We recently deployed a DaemonSet called logs-cka26-trb under kube-system namespace in cluster2 for collecting logs from all the cluster nodes including the controlplane node. However, at this moment, the DaemonSet is not creating any pod on the controlplane node. Troubleshoot the issue and fix it to make sure the pods are getting created on all nodes including the controlplane node. Answer:  ------ Check the status of DaemonSet kubectl --context2 cluster2 get ds logs-cka26-trb -n kube-system You will find that DESIRED CURRENT READY etc have value 2 which means there are two pods that have been created. You can check the same by listing the PODs kubectl --context2 cluster2 get pod -n kube-system You can check on which nodes these are created on kubectl --context2 cluster2 get pod <pod-name> -n kube-system -o wide Under NODE you will find the node name, so we can see that its not scheduled on the controlplane node which is because it must be missing the reqiured tolerations. Let's edit the DaemonSet to fix the tolerations kubectl --context2 cluster2 edit ds logs-cka26-trb -n kube-system Under tolerations: add below given tolerations as well - key: https://lnkd.in/gF_VD8iu  operator: Exists  effect: NoSchedule Wait for some time PODs should schedule on all nodes now including the controlplane node. --------Done------- Feel free to comment on queries related to Kubernetes CKA.
