The worst thing that can happen to a startup are users

Code repository

Google Cloud source repositories

Github

Bitbucket

Gitlab

Continuous integration

Essential process

Single point where all kind of apps get build

Jenkins is the swiss knife

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'

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:./

How to run the apps

Monolithic VPS

Application platform (such as Cloud Foundry)

Containers (…Docker)

Dockerfile

FROM node:5.12.0ENV NODE_PATH=./config:./appWORKDIR /usr/src/app

# Bundle app sourceCOPY . /usr/src/appEXPOSE 3000CMD [ "npm", "start" ]
