Profile

Simple CRUD service for users with the ability to notify other subscribed services.

Assumptions:

• User email and password are required fields.
• Only up migrations are supported.

ToDos:

• Proper password storing: hash function.
• Prometheus metrics.
• TraceID/RequestID in logs and other logging improvements, that can be useful.
• Postgres tests.
• REST API generated specification.
• Write country service or find the better one.
• GithubActions to run linter, tests, build a docker image.
• Limit param for /users.
• Check goroutines leaks.

Run tests and linter

make test lint

How to run locally:

docker compose build
docker compose up

curl -v -X POST "http://localhost:8080/users" -H "Content-Type: application/json" -d '{"email": "[email protected]", "password":"pwd"}'

Kubernetes setup

kubectl create secret generic postgres-secret --from-literal=user=root --from-literal=pass=toor

kubectl create secret generic postgres-db-url --from-literal=db-url="postgresql://root:toor@postgres:5432/profile?sslmode=disable&application_name=profile"

kubectl create configmap backend-config-v5 --from-env-file=profile.properties

// run postgres
kubectl apply -f postgres.yaml

// prepare local image
eval $(minikube docker-env)
docker build -t profile .

// add ingress-controller (example for minikube)
minikube addons enable ingress
minikube tunnel

// run backend
kubectl apply -f service.yaml
kubectl apply -f backend.yaml
kubectl apply -f ingress.yaml

// check api
curl -v -X POST "http://127.0.0.1:80/users" -d '{"name": "test", "email": "[email protected]", "password": "Pass"}' -H "Content-Type: application/json"

// change minikube env back
eval $(minikube docker-env -u)
