Docker and Kubernetes orchestration training

Containerization is the process of encapsulating an application in a container, which allows it to run in any environment without dependencies on the host operating system.
Docker and Kubernetes are popular tools used for containerization, allowing developers to package and deploy applications quickly and efficiently.

Docker Architecture

Docker uses a client-server architecture to manage containers.
The Docker client communicates with the Docker daemon, which manages container images, creates and runs containers, and communicates with the Docker Hub registry.
Containers are isolated from each other and from the host operating system, which improves security and reduces conflicts.

Kubernetes Architecture

Kubernetes is an open-source platform for managing containerized workloads and services.
It uses a master node to manage worker nodes, which run containers and communicate with the master node.
Kubernetes provides features for scaling, load balancing, and self-healing, making it an ideal choice for large-scale deployments.

Microservices Architecture

Microservices architecture is a way of designing software as a collection of small, independent services that communicate with each other.
This architecture allows for easier scaling, updating, and testing of individual services without affecting the entire application.
Docker and Kubernetes are often used in microservices-based applications to provide containerization and orchestration.

Best Practices for Docker and Kubernetes Architecture

Use the smallest possible base image for containers to reduce image size and improve security.
Use Kubernetes namespaces to isolate different environments (e.g. production, staging, development).
Use Kubernetes labels and annotations to provide metadata about resources.
Monitor container and cluster health using Kubernetes built-in monitoring tools.

Topic 2: Docker and Kubernetes Monitoring and Logging Training

Notes: This training will cover the basics of monitoring and logging in Docker and Kubernetes environments. Participants will learn how to set up monitoring and logging tools, collect metrics, and set up alerts to detect and resolve issues.
Monitoring is the process of observing the state of a system or application, while logging is the process of recording events and errors for analysis and troubleshooting.
In Docker and Kubernetes environments, monitoring and logging are essential for maintaining performance, detecting issues, and resolving them quickly.

Docker Monitoring and Logging

Docker provides built-in logging functionality that can be configured to send logs to different destinations, such as the console, a file, or
