Hello people, on 3rd November 2022 I had amazing opportunity to speak at AWS community (Vadodara) event happening in my city. I presented on using Authorizer with DynamoDB and EKS.
Authorizer is database independent open source auth solution. It supports 12+ databases including all the major SQL, NoSQL and Graph databases.
So, as a part of demo I created a Task Manager (TODO) application, which will allow authenticated user to
- Create Task
- Watch their own tasks
- Mark Task as done
- Delete Task
The tech stack we will be using is:
- DynamoDB to store user information and tasks
- Authorizer to authenticate and authorize users
- GoLang Gin Server to create tasks apis
- React to create frontend application
- EKS to deploy authorizer & go-gin server
- Netlify to deploy frontend application
Here is a small architecture diagram demonstrating how the overall application will look like
Code Repository
Github Repository: This repository contains code for TODO API, Frontend Application, EKS Cluster Creation, Ingress / Domain Setup
Let's Get Started
Prerequisite
- aws account
- iam user with permission for DynamoDB, EKS, EC2, IAM Policy Creation, Route53, EBS Controller
- kubectl
- awscli
- eksctl
- helm
- Configure AWS profile on your machine with user credentials
- Export your AWS credentials
aws configure --profile PROFILE_NAME
export AWS_PROFILE=PROFILE_NAME
export AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY_ID
export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_ACCESS_KEY
Step 1: Clone the Repository
git clone https://github.com/lakhansamani/authorizer-aws-demo.git
cd authorizer-aws-demo
Step 2: Create EKS Cluster
Note: You can update machine configuration in eks.yaml file.
eksctl create cluster -f eks.yaml
Step 3: Install Nginx Ingress
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx \
--namespace ingress-nginx \
--create-namespace \
--timeout 600s \
--debug \
--set controller.publishService.enabled=true
Step 4: Install Cert Manager
Cert manager is used to generate TLS certificate
helm repo add jetstack https://charts.jetstack.io
helm repo update
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.8.2/cert-manager.crds.yaml
helm install \
cert-manager jetstack/cert-manager \
--namespace cert-manager \
--create-namespace \
--version v1.8.2
Step 5: Install Authorizer
Note: Please change
authorizer.authorizer_url
as per your domain and URL.
helm repo add authorizer https://helm-charts.authorizer.dev
helm repo update
helm install \
--set authorizer.database_type=dynamodb \
--set authorizer.aws_access_key_id=${AWS_ACCESS_KEY_ID} \
--set authorizer.aws_secret_access_key=${AWS_SECRET_ACCESS_KEY} \
--set authorizer.aws_region=us-east-1 \
--set authorizer.authorizer_url=https://auth.aws-demo.authorizer.dev \
--set redis.install=true \
--set redis.storage=5Gi \
--set redis.storageClassName=gp2 \
--set securityContext.readOnlyRootFilesystem=false \
authorizer authorizer/authorizer
Step 6: Create Route53 Hosted Zone
- Create Hosted Zone
- Create Subdomain Record with classic load balancer and select loadbalancer created by nginx
Example: auth.aws-demo.authorizer.dev
in below screenshot
Step 7: Create Cluster Issuer with dns01 challenge
Note: Change email & hostzoneID as per step5 in
cluster_issuer.yaml
Cert manager will add txt record and will verify the domain details using this issuer.
kubectl apply -f cluster_issuer.yaml
Step 8: Create Ingress for authorizer
Note: Change authorizer domain as per your auth domain in
authorizer_ingress.yaml
kubectl apply -f authorizer_ingress.yaml
Open your authorizer dashboard, configure admin password and get client ID.
Step 9: Deploy API resources
Note: Change
authorizer_client_id
to based64 encoded value authorizer client_id value obtained in step 7 in api.yaml L:8. Also change domain name in ingress section.
kubectl apply -f api.yaml
Step 10: Deploy frontend
You can deploy frontend to provider of your choice OR on the same stack. For demo purpose I have deployed it on Netlify and connected subdomain there.
Thats all you need. Hope it makes your life easier to deploy authorizer + any other service on AWS
