System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

My Openshift Cheatsheet

Openshift build secrets for cloning git repos using SSH Keys

To create ssh secret:

oc create secret generic sshsecret \
    --from-file=ssh-privatekey=$HOME/.ssh/id_rsa

	#!/usr/bin/env bash

	set -u
	set -e
	set -o pipefail

	GCP_PROJECT="$(gcloud config list --format 'value(core.project)')"

	GCP_SERVICES=(
	"storage-api.googleapis.com"

	#Login to openshift and retrieve token
	curl -u admin -kv -H "X-CSRF-Token: xxx" \
	'https://master.cluster.local:8443/oauth/authorize?client_id=openshift-challenging-client&response_type=token'

	#It should give you a bearer token like this
	https://master.cluster.local:8443/oauth/token/implicit#access_token=aRVmsEHbUEhd4WeP2bctj0n57ogHMBvOIcrtjc7tCw4&expires_in=86400&scope=user%3Afull&token_type=Bearer

	TOKEN="aRVmsEHbUEhd4WeP2bctj0n57ogHMBvOIcrtjc7tCw4"

	#Get a configmap named configmaptest

	pipeline {
	agent {
	node {
	label 'maven'
	}
	}

	environment {
	microserviceName = "demo-ms"
	namespaceName = "sample-project"
