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.
The talk will go as follows;
- Brief Introduction
- What is a container
- Containers vs VMs
- Getting started with Docker
- Images vs Containers
- Let's make a basic image
- Using Apache Docker image for development
- 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 >.>
- Issues regarding dependencies
- 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
- The dark ages of VMs
- Conclusion
