The document discusses building and deploying software using containers and Kubernetes. It begins by introducing the author and their expertise in distributed systems, microservices, containers and Kubernetes. It then outlines the complexities of running software beyond just writing code, such as resource scheduling, monitoring, load balancing etc. It introduces Docker as a standard for dependencies, and Kubernetes to describe the desired state for deploying containers at scale addressing questions like resources, configuration, networking and restarts. Finally, it provides links to the author's GitHub and YouTube channel for examples.

4. Building and Deploying Software
Write Code Write Tests Build Run Deploy

5. It’s not that simple

6. Running Software
● Resource Scheduling & Utilization
● Monitoring and logging
● Scalability
● Load Balancing
● Networking
● Service Discovery
● Restarts

7. Write Code Write Tests Build Run Deploy ● Resource
Scheduling
● Monitoring and
logging
● Scalability
● Load Balancing
● Networking
● Service Discovery
● Restarts
- docker build
- docker push
- docker run

8. Docker
● It’s a standard
○ Describing our dependencies
○ Readable
○ People can follow it (Dev + Ops)
○ Build
○ Push
○ Run
● Source of Truth
○ Version Control
● Containers are enablers
● You don’t need anything installed on a
server but Docker

9. Kubernetes
● What docker image do you want to run?
● How many instances of our application ?
● How do you want deployments to occur?
● What configuration do you want?
● How much CPU do you need ?
● How much Memory do you need ?
● Can we restart your app if it becomes
unhealthy ?
● Do you need HTTP traffic ?
○ Port ?
○ SSL ?
