Create a python flask application, build a custom container image, and deploy it to a web server with chatgpt guidance, while organizing code files and managing requirements.txt.

Learn to deploy a dockerized app using ChatGPT by resolving Flask and Jinja2 compatibility, manage containers, and view a deployed container URL as you build your first Docker application.

Explore alternative Dockerfile patterns, including multi-stage builds, argument variables, .dockerignore, labels, and environment variables, with notes on the expose keyword and entrypoint usage.

Explain the difference between cmd and entrypoint in Docker, showing how defaults and always-running commands behave, and preview pushing images to Docker Hub and aws elastic container registry.

Learn how to push images to the Docker Hub container registry, including logging in with docker login and verifying the image before pushing, and the next video covers AWS ECR.

Explore how AWS elastic container registry (ECR) securely stores, manages, and deploys Docker images with IAM and VPC integration, scales with demand, and enables a simple push to ECR workflow.

Learn to use ChatGPT to explore Kubernetes concepts and gain hands-on experience with port nodes, config maps, secrets, and deployment with Minikube and Kubernetes configuration files.

Define Kubernetes as an open platform for automating deployment, scaling, and management of containerized apps, with self-healing and rollback. Contrast Kubernetes with Docker by emphasizing scalability, load balancing, and resilience.

Explore the Kubernetes architecture, its API server as the central component, etcd for state, and the controller manager, scheduler, and kubectl coordinating pods and containers through the runtime, with self-healing.

Explore how the Kubernetes service provides a stable endpoint for ephemeral pods via a fixed IP and DNS, with cluster IP, node port, load balancer, and external name options.

Explore how Kubernetes pods run one or more containers with an IP, resource limits, volumes, labels and selectors, and how ChatGPT explains deployment and service relationships.

Learn how Kubernetes master (control plane) and worker nodes operate, from container runtime, kubelet, kube-proxy to API server, scheduler, and controller manager, and how pods run on workers.

Explore volumes in Kubernetes to store data for pods and containers, mounted with path, via a yaml with api version, kind, metadata, and spec, including hostpath, configmap, secret, or empty.

Learn how a Kubernetes deployment configuration file defines the desired state for pods. Understand replicas, selectors, and templates, and how the deployment controller updates pods and manages replica sets.

Explore kubernetes config maps that store non-confidential data as key-value pairs to externalize configuration, enabling environment variables, CLI arguments, and config files, and avoid rebuilds when endpoints change via ChatGPT.

Explore Kubernetes secrets and how they differ from config maps, including base64 encoding in etcd, and why encryption requires external tools. Learn practical creation and use with kubectl and customize.
