Day 8 of learning about Kubernetes: 𝐋𝐚𝐮𝐧𝐜𝐡𝐢𝐧𝐠/𝐒𝐭𝐨𝐩𝐩𝐢𝐧𝐠 𝐨𝐟 𝐏𝐨𝐝𝐬 𝐛𝐚𝐬𝐞𝐝 𝐨𝐧 𝐋𝐚𝐛𝐞𝐥𝐬 In Kubernetes, 𝐑𝐞𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐂𝐨𝐧𝐭𝐫𝐨𝐥𝐥𝐞𝐫 is responsible for launching/stopping the pods. But how does it know, when to start/stop the pods?? Actually, RC keeps searching for the labels and if it does not have desired number of labels as stated, it will launch that many new replicas. Hence, 𝐋𝐚𝐛𝐞𝐥𝐬 play vital role in working of RCs. #kubernetes #learning #day8 #dailyseries #rc #replicationcontroller #labels #devops

Learning Docker to Kubernetes for the Modern Developer Two novel paradigms key for today’s software development environment include consistency, efficiency, and scalability. Now docker and kubernetes has become inevitable to deal with the complexities emerged with development and deployment. Key Insights: The Problem: Fluctuating environments and dependency problems may hamper development, while manual configuration and scalability are problems in the deployment process. Docker to the Rescue: Instead of attempting to deploy an application and all of the dependencies that it needs in one go, Docker provides an efficient environment through the use of containers. Orchestration with Kubernetes: Although applications in containers are progressing, the management of such containers becomes essential. Kubernetes, the agenda orchestration platform, does this automatically in production contexts. Their understanding makes it possible for developers to create enterprise level, reliable applications with little effort. I would like to get acquainted with Scaler which is a wonderful tutorial for enhancing the understanding about these topics. #Docker #Kubernetes #Microservices #DevOps #SoftwareDevelopment #SDLC #Scaler #PythonProgramming #ApacheAirflow #DataEngineering #WebDevelopment #Forms #ModelForms #CSS #ApacheSpark #Python #AI #PostgreSQL #PySpark #Databricks #DataPipelines #Airflow #pgAdmin #Git #Ubuntu #VirtualEnvironments #OpenAI #ChatGPT #JavaScript #TechSkills #ContinuousLearning #ProfessionalDevelopment #ScalerAcademyLearning #Coding #WebDesign #FormValidation #DataHandling #UserExperience #TechEducation #Programming #DeveloperSkills

📖 I recently explored several key concepts in Kubernetes, including Node Selector, Labels and Selectors, Static Pods, and Manual Scheduling. These tools are vital for fine-tuning pod placement and managing workloads effectively.

🌟 Day 42 of Learning Kubernetes via Troubleshooting: CrashLoopBackOff Error 🌟 Today, I explored why containers keep crashing and restarting in Kubernetes, known as the CrashLoopBackOff error. Misconfigurations, liveness probe errors, low memory limits, and wrong command line arguments are common culprits. By understanding these issues, I learned how to prevent them and keep my Kubernetes environment running smoothly. Have you faced this error before? How did you tackle it? 🚀 #Kubernetes #DevOps #Learning #Troubleshooting Abhishek Veeramalla
