Monolith to Microservices at Scale

Build project via docker

Make sure to setup AWS configuration

aws configure

Setup environment varriables file (.env)

POSTGRESS_USERNAME=**********
POSTGRESS_PASSWORD=**********
POSTGRESS_DB=**********
POSTGRESS_HOST=**********
AWS_REGION=**********
AWS_PROFILE=**********
AWS_BUCKET=**********
JWT_SECRET=**********
URL=http://localhost:8080

import environment varriables

source .env

Build all system docker images

docker-compose -f udacity-c3-deployment/docker/docker-compose-build.yaml build --parallel

Run all system docker images locally

cd udacity-c3-deployment
docker-compose up

Deploy project to AWS with Kuberenetes & CubeOne

install Terraform https://learn.hashicorp.com/terraform/getting-started/install.html

Clone CubeOne repository https://github.com/kubermatic/kubeone/blob/master/docs/quickstart-aws.md

Unzip CubeOne repository and move to example folders

cd ./examples/terraform/aws

update variiables file as needed (varriables.tf)

Build and publish kuberentes cluster

source .env
terraform init
terraform plan
terraform apply
terraform output -json > tf.json
kubeone install config.yml --tfjson tf.json

kubectl --kubeconfig=../**cluster config file** apply -f env-config.yml
kubectl --kubeconfig=../**cluster config file**  apply -f env-secret.yml
kubectl --kubeconfig=../**cluster config file**  apply -f aws-secret.yml

kubectl --kubeconfig=../**cluster config file**  apply -f feed-deployment.yml
kubectl --kubeconfig=../**cluster config file**  apply -f backend-feed-service.yaml

kubectl --kubeconfig=../**cluster config file**  apply -f user-deployment.yml
kubectl --kubeconfig=../**cluster config file**  apply -f backend-user-service.yaml

kubectl --kubeconfig=../**cluster config file**  apply -f reverseproxy-deployment.yml
kubectl --kubeconfig=../**cluster config file**  apply -f reverseproxy-service.yaml

kubectl --kubeconfig=../**cluster config file**  apply -f frontend-deployment.yml
kubectl --kubeconfig=../**cluster config file**  apply -f frontend-service.yaml

To forward cluster port to local pc for test

kubectl --kubeconfig=../**cluster config file**  port-forward service/reverseproxy 8080:8080
kubectl --kubeconfig=../**cluster config file**  port-forward service/frontend 8100:80

To scale deployments

kubectl --kubeconfig=../**cluster config file**  scale deployment/backend-feed --replicas=2

To destroy kuberentes cluster

kubeone reset config.yml --tfjson tf.json
terraform destroy
