Functional Scala 2021

Projects contains 2 subprojects:

• external-secret-opeartor
• login-app

External Secret Operator

Kubernetes operator that syncs secrets from AWS Secret manager into K8s Secrets.

You can build it using:

sbt operator/docker:publishLocal

It will build and publish docker image of operator in your local docker registry.

To deploy it in local cluster (docker-desktop, minikube) you can use command

kubectl apply -f k8/operator

It will create these kubernetes objects:

• operator namespace
• aws-secert Secret that will be used to communicate with AWS API
• externa-secret-operator ServiceAccount
• external-secret-operator-role Role
• external-secret-operator-role-binding RoleBinding
• externa-secret-operator Deployment
• externa-secret-operator Service

In aws-secert Secret you should add your AWS credentials.

Login app

ZIO Http app that exposes endpoint to test authentication using secret data.

You can build it using:

sbt loginApp/docker:publishLocal

It will build and publish docker image of login app in your local docker registry.

To deploy it in local cluster (docker-desktop, minikube) you can use command

kubectl apply -f k8/app

It will create these kubernetes objects:

• login-app Service account
• login-app Deployment
• login-app Service

Befor testing it you should port forward port so that it is accessible outside of K8s cluster using

kubectl port-forward service/login-app  9000:9000

Now you can test it using

curl -i  localhost:9000/login/jkobejs/functionalscala2021

External secret

Before creating external secret you should create on your AWS account functionalscala2021 secret with username and password.

Now when you create external sercret using

kubectl apply -f k8/externalsecrets

External secret operator will sync it into your cluster and you can call login app to see if it works.
