Containers help applications easily be packaged and shipped to any environment. Two of the most popular container tools are Docker and Kubernetes. Depending on their utilization, containers can experience image build, pods and node failures, and communication issues. This course will help you learn how to handle those issues. This course teaches you what containers are and why they were adopted. You’ll explore Docker images, review log files in Docker, inspect containers, and clean resources while learning to fix issues with Docker image builds and resolving Docker container network errors. Then, you’ll get an overview of Kubernetes, how to manage a cluster and resolve reliability issues, and how to fix pod, network, container, configuration, and ingress issues. Finally, you’ll create a robust container infrastructure. By the end of this course, you’ll also have a strong grasp on approaching and handling container issues and troubleshooting various issues in Docker and Kubernetes.
