In this cloud native 5-day bootcamp, students will quickly learn the core skills they need to develop high performance, secure containerized applications and orchestrate them on Kubernetes before deep diving into advanced techniques for streamlining the container development process, instrumenting containers for production systems, and building fully containerized continuous integration pipelines. This bundle is meant to accelerate the containerization journey for developers and devops teams, by helping them take full advantage of all the opportunities containerization offers.
 

Containerization motivations and implementation

• Usecases
• Comparison to virtual machines

Creating, managing and auditing containers

• Container implementation from the Linux kernel
• Container lifecycle details
• Core container creation, auditing and management CLI

Best practices in container image design

• Layered filesystem implementation and performance implications
• Creating images with Dockerfiles
• Optimising image builds with multi-stage builds and image design best practices

Single-host container networking

• Docker native networking model
• Software defined networks for containers
• Docker-native single-host service discovery and routing

Provisioning external storage

• Docker volume creation and management
• Best practices and usecases for container-external storage.

Make effective use of pod architecture

Deploy workloads as Kubernetes controllers

Provision configuration at runtime to Kubernetes workloads

Network pods together across a cluster using native services

Provision highly available storage to Kubernetes workloads

Package an application as a Helm chart

Container Development Environments
