Docker

Docker is probably the most used containerisation platforms in the market at the moment?

What's a container I hear you say, and by coming to this talk you'll hopefully end up learning about what they are and why you should use it.

It's more a tool used in industry for deployment of applications but with the soon coming NetSoc Containers-as-a-Service platform you will soon be able to host your own applications in containers, and then you'll never look back.

Roadmap

The talk will go as follows;

1. Brief Introduction
   • What is a container
   • Containers vs VMs
2. Getting started with Docker
   • Images vs Containers
   • Let's make a basic image
   • Using Apache Docker image for development
3. Case Study of CIX
   • The dark ages of VMs
     • Issues regarding dependencies
       • Old deploy scripts didn't / don't properly update dependencies
     • Monolithic / Microservice
       • Old code all on single server
       • New stuff being deployed on multiple servers for load balancing / failover
     • Stupid issues
       • Server clock discrepencies causing issues with tokens >.>
   • The new age of Docker / Kubernetes
     • Dependencies are handled when building the image, not after deploying code
     • Once image is built, that's all that has to be deployed
     • Kubernetes clusters allow for load balancing, automatic rollout of upgrades to prevent downtime, failover etc
4. Conclusion
