1001 lives of containers in the cloud What is a container anyway? A way to create lightweit, portable and self- sufficent packages for your application. Docker is the most used containerization techology. It’s an open-source project.

1001 lives of containers in the cloud | How containers can help developers? Start working on a project quickly Write and execute code quickly without having to install anything Debug my code as usual Use docker for CLI tools Create your own docker container Use Visual Studio Code to debug within a container 

1001 lives of containers in the cloud | How containers can help developers? Share an environment configuration with other developers Use and share pre-build containers through registries Hub.docker.com Azure Container Registry Use containers as a way to build your code in a CD/CI env. Build container pattern ( multi-stage builds) Use volume mapping + run command docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.8 go build -v 

1001 lives of containers in the cloud | How containers can help developers? Deploy apps more safely Docker containers self-contain your app, eliminating any dependency issues Deploy on-demand apps for testing purposes Azure Container Instances Simplify A/B testing, carany deployments, etc… Azure Web Apps + Slots Deploy your apps anywhere! Your dev machine, all clouds, on customer’s infrastructure, on some IoT Devices (Azure IoT Hub), etc… 

1001 lives of containers in the cloud | How containers can help developers? Test new framework versions with ease FROM node:8 WORKDIR /usr/src/app COPY package*.json ./ FROM node:8.15.0-jessie WORKDIR /usr/src/app COPY package*.json ./ Tags allows you to specifiy a specific version to use. Your own (base) images can have a tag. You can use latest to get the most recent version, this can be used in your CD/CI environment to test your code nightly against the latest/nightly version of your stack. 

1001 lives of containers in the cloud Containers for production: some challenges How do you manage persisted state? How do you scale your service to several nodes? How do you implement a self-healing infrastructure? How do compose services using different containers? How do you aggregate logs from all containers & hosts ? You need an orchestrator & some cloud services!

Open source project started by Google in 2014 container-centric vs. host-centric schedules and runs application containers across a cluster of machines portable: public, private, hybrid, multi-cloud extensible: modular, pluggable, hookable, composable self-healing: auto-placement, auto-restart, auto-replication, auto- scaling Provides resource monitoring, load balancing, naming & discovery, horizontal auto-scaling Has cloud provider integration (Eg - Azure networking, Azure disks)
