This document provides an overview of Docker and Kubernetes concepts and demonstrates how to create and run Docker containers and Kubernetes pods and deployments. It begins with an introduction to virtual machines and containers before demonstrating how to build a Docker image and container. It then introduces Kubernetes concepts like masters, nodes, pods and deployments. The document walks through running example containers and pods using commands like docker run, kubectl run, kubectl get and kubectl delete. It also shows how to create pods and deployments from configuration files and set resource limits.

This document provides an overview and demonstration of Bootstrap, an open-source front-end framework for developing responsive, mobile-first web sites and applications. It discusses Bootstrap's support for responsive design using LESS, its grid system, and included UI components like buttons, forms, navigation, and more. The document also demonstrates how to get started with a basic Bootstrap template and use its grid system, breakpoints, containers and columns. Finally, it mentions some tools for working with Bootstrap and provides details on Font Awesome, an icon library that is often used along with Bootstrap.

Docker is a tool that allows users to package applications into containers to run on Linux servers. Containers provide isolation and resource sharing benefits compared to virtual machines. Docker simplifies deployment of containers by adding images, repositories and version control. Popular components include Dockerfiles to build images, Docker Hub for sharing images, and Docker Compose for defining multi-container apps. Docker has gained widespread adoption due to reducing complexity of managing containers across development and operations teams.

Flexbox is a modern layout method in CSS that allows for flexible and responsive page layouts. It addresses shortcomings of older methods like floats, tables, and inline blocks by allowing for full control over alignment, order, and distribution of space between items. Flexbox makes it easy to create complex responsive layouts that were previously difficult to achieve without hacks. While not a silver bullet, flexbox excels at component-based and content-driven page layouts. Tools like autoprefixer and fallbacks help provide support for older browsers.

MySQL InnoDB Cluster provides a complete, high-availability solution for MySQL. Learn how with a few easy-to-use Shell commands, how to set up a MySQL database architecture.

Docker is an open platform for developing, shipping, and running distributed applications. It allows applications to be shipped and run in lightweight containers that can run on any Linux server. Docker uses operating-system-level virtualization and cgroups isolation to deliver lightweight containers quickly. Key features of Docker include portability, lightweight containers that share resources and isolate processes, and automated workflows.

An introduction to the changing world of CSS. Slides from Brisbane Web Designer Meetup 13 March 2013.

Modules are containers that define an AngularJS application and hold parts like controllers, services, and directives. A module is used as the main entry point and starting point of an app. Controllers must belong to a module to avoid issues like global overriding. To create a module, use the angular.module method, passing in a name and empty array. Controllers can then be added to the module using the module's controller method.

Docker Swarm allows managing Docker clusters remotely. The key components are swarm managers, swarm nodes, and a scheduler. Swarm managers oversee nodes in the cluster using Docker APIs. The scheduler uses strategies and filters to determine where to place containers on nodes. Discovery services help register and discover nodes in the cluster.

ProxySQL is a MySQL protocol proxy that provides high availability, scalability, and security for MySQL database systems. It allows clients to connect to ProxySQL, which then evaluates requests and performs actions like routing queries to backend databases, caching reads, connection pooling, and load balancing across servers. ProxySQL's main features include query routing, firewalling, real-time statistics, monitoring, and management of large numbers of backend servers. The presentation discusses using ProxySQL's query routing and rewriting capabilities to mask sensitive data when replicating databases for development environments. It also covers using the REST API and Prometheus integration to configure ProxySQL and monitor metrics without direct SQL access.

Docker allows applications to be packaged with all their dependencies and run consistently across computing environments. It provides isolation, security and portability for applications. This document discusses setting up an Eh Avatar application to run in Docker containers for Postgres, Redis and the application itself. It covers bringing up the dependency containers, building a custom Docker image for the application, and using Docker Compose to define and run the multi-container application. While this provides an introduction, there is still more to learn about optimizing Docker usage and avoiding common pitfalls.

In this presentation we take you through the concept of virtualization which includes the different types of virtualizations, understanding the Docker as a software containerization platform like Docker's Architecture, Building and running custom images in Docker containers, Scalable container management services which include overview of Amazon ECS & kubernetes and how at LimeTray we harnessed the power of kubernetes for scalable automated deployment of our microservices.
