This document discusses how to get an app into production in 3 months using containers and Kubernetes. It covers setting up continuous integration with Jenkins, building Docker images, running automated tests, and deploying containers to Kubernetes. Kubernetes is recommended for orchestrating containers and managing resources, load balancing, logs, and auto-scaling of replicas. Google Container Engine is suggested for hosting Kubernetes due to its built-in support and features like health checks, monitoring, and alerts.

1. Get your app into production in 3 months
Josef Gattermayer, co-founder

2. Case study: App4Fest

3. Case study: App4Fest
Mobile apps (Android, iOS)
Backend (Node.Js API server)
Web administration (React)
Web app (React)

4. DevOps and Infrastructure
Josef Gattermayer, CIO

5. The worst thing that can happen to
a startup are users

6. Code repository
Google Cloud source repositories
Github
Bitbucket
Gitlab

8. Continuous integration
Essential process
Single point where all kind of apps get build
Jenkins is the swiss knife

10. Jenkins pipeline as a code
stage 'Checkout'
checkout scm
stage 'Build Docker image'
sh("docker build -t ${imageTag} .")
stage 'Run Docker tests'
…
stage 'Run Docker lint'
…
stage 'Push image to registry'
sh("gcloud docker push ${imageTag}")
stage 'Create namespace for app'

11. Jenkins pipeline as a code
buildNodejs{
// MODIFY
projectName = ‘node-template'
slackChannel = '#ci-nodetemplate'
appName = ‘node-template'
cloudProject = [development: 'infrastruktura-1307',
master: ‘ackee-production']
buildCommand = 'npm install && npm run postinstall'
// MODIFY ONLY IF YOU KNOW WHAT YOU ARE DOING
nodeImage = 'node:5.12.0'
nodeEnv = "-e NODE_PATH=./app:./config"
nodeTestEnv = '-e NODE_ENV=test -e NODE_PATH=./app:./

12. How to run the apps
Monolithic VPS
Application platform (such as Cloud Foundry)
Containers (…Docker)

13. Dockerfile
FROM node:5.12.0
ENV NODE_PATH=./config:./app
WORKDIR /usr/src/app
# Bundle app source
COPY . /usr/src/app
EXPOSE 3000
CMD [ "npm", "start" ]

14. Orchestration
Way to manage containers
Docker Compose
Kubernetes

15. Kubernetes
Open-source or hosted
Run / Stop / Restart a container
(Auto) Scale up / down
Manage resources
Load balance traffic
Manage logs

16. Kubernetes
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: APP_NAME
spec:
replicas: 2
spec:
containers:
- name: APP_NAME
image: IMAGE_URL
env:
- name: TZ
value: "Europe/Prague"

17. Kubernetes
resources:
requests:
memory: "128Mi"
cpu: "5m"
limits:
memory: "256Mi"
cpu: "80m"
ports:
- name: frontend
containerPort: 3000

18. Where to run the apps
Own HW/VPS
Amazon EC2
Google Container Engine

19. Google Container Engine
Built-in Kubernetes support
WebGUI + command line interface
Health Checks
Container Registry
Monitoring
Alerts
