# k8s-playground
Playground for k8s
## Dummy todo app
- Tech stack : React JS + Golang + Postgres
- Download and save the file as `docker-compose.yaml`
```yaml
version: '3.8'
services:
postgres:
image: postgres:13
environment:
POSTGRES_DB: tododb
POSTGRES_USER: todouser
POSTGRES_PASSWORD: todopassword
volumes:
- postgres-data:/var/lib/postgresql/data
# ports:
# - "5432:5432"
backend:
image: aswinbenny/todo-backend:v1
environment:
- DB_HOST=postgres
- DB_USER=todouser
- DB_PASSWORD=todopassword
- DB_NAME=tododb
- DB_PORT=5432
volumes:
- backend:/app
depends_on:
- postgres
ports:
- "8080:8080"
frontend:
image: aswinbenny/todo-frontend:v1
ports:
- "3000:80"
depends_on:
- backend
volumes:
postgres-data:
backend:
```
- Do `docker compose up` to run the app
- The app will run in `http://localhost:3000`
- The file will be uploaded to `/app/uploads` folder in the backend volume
- Backend runs in `http://localhost:8080`
## K8s stuff
- Visit k8s folder
```bash
kind create cluster --config kind-cluster.yaml --name todo-cluster
```
```bash
kubectl cluster-info --context kind-todo-cluster
```
- apply yaml files one at a time : postgres > backend > frontend
```bash
kubectl apply -f
```
- Port forward to test
```bash
kubectl port-forward svc/frontend-service 8081:80
kubectl port-forward svc/backend-service 8080:8080
```
- Visit http://localhost:8081
