Learn to define, build & orchestrate services, networks & volumes with Docker Compose. Simplify multi-container apps, manage lifecycles & enable seamless container communication.

Bind mounts allow specific host files/directories to be mapped to container files/directories, enabling seamless interaction between host & container. They're flexible, support direct modifications & can't be used in Dockerfiles.

Docker volumes persist container data & offer a clean abstraction. Key features: storage location, Docker management, resilience & ease of use. Use `docker volume create`, `ls` & `inspect` to manage.

Dockerfile is a text doc with build instructions for Docker images. It's composed of read-only layers, each layer corresponding to an instruction like FROM, LABEL, or RUN. Docker automatically creates images by interpreting these instructions.

Docker container images are at the core of containerization technology, enabling efficient & scalable app deployment. Manage Docker images using Docker Hub, a central repository for storing public & private repos.

Docker Networking: Containers & Host Machine Connection. Docker uses bridge, overlay networks & CNI for container communication. Create custom networks for specific purposes & use essential Docker commands to manage & inspect networks & containers.

Containers offer efficiency, consistency, portability & scalability for modern app deployment. They're lightweight packages with code, runtime, tools & libraries, stored on Docker Hub.

Install Prometheus stack with Helm, expose services using kubectl port-forward, collect metrics with node_exporter & kube-state-metrics, query metrics in Prometheus, create Grafana dashboards to visualize metrics.

Deploy a Python Flask app on AWS ECS with Fargate in 7 steps: Prepare app & Docker image, build & push to ECR, create ECS cluster, define task definition, run task, access app, clean up resources.

Set up EKS cluster with eksctl, install Prometheus & Grafana using Helm, verify installation & clean up resources

Observability is key to understanding system behavior & diagnosing issues. It collects logs, metrics & traces for full visibility, while monitoring focuses on tracking specific metrics & generating alerts. Monitoring is a subset of observability.

AWS Lambda optimizes cloud cost by automating tasks like EBS snapshot management, reducing infrastructure overhead & costs for DevOps engineers.

Imperative vs Declarative Kubernetes Management: Imperative issues commands, while declarative uses YAML files for desired state.

Install kind for local Kubernetes clusters, create a single-node or multi-node cluster, install kubectl, verify cluster status, deploy applications & test.

Docker multistage builds reduce image size, enhance security & optimize build process by selectively copying artifacts between stages. Ideal for CI/CD pipelines & microservices.

Docker Tutorial For Beginners: Learn Docker fundamentals, architecture, components (Client, Docker Host, Docker Daemon, Dockerfile, Registry, Image, Container) and workflow steps (build, push, pull, run).

Restrict S3 bucket access with IAM users & policies, then host a static website on S3 by enabling static hosting & adjusting permissions for public read access.
