Implementation guide

For Ubuntu

1. Clone the repo
2. Install and configure microk8s
3. Enable metallb
4. Run the DB deployment
5. Run the API deployment

1. Clone it

git clone https://github.com/NelsonLopez69/API-Kubernetes.git

---

2. Install microk8s

Install MicroK8s from the command line:

sudo snap install microk8s --classic

Add the user [yourUser] to the 'microk8s' group:

sudo usermod -a -G microk8s [yourUser]
sudo chown -f -R [yourUser] ~/.kube

Restart or update de microk8s group

newgrp microk8s

3. Enable MetalLB

microk8s enable metallb:10.64.140.43-10.64.140.49

---

4. RUN DB deployment

microk8s kubectl apply -f deployment-db.yml

---

5. RUN API deployment

microk8s kubectl apply -f deployment-api.yml

Enjoy!

Now you can use the app. Try inserting 10.64.140.44 in your browser. Routes:

• /
• /health

Example: http://10.64.140.44/health

For a productive environment

• For a productive environment, it would ne nice to have a DNS so we can redirect de traffic to the public IP of the load balancer.

• If the implementation takes place in an on premise environment an Horizontal Autoscaler could help improve the scalability. In the cloud there are tools that already help with it.

• The deployment could be moved to the cloud for cost reduction and more disponibility.

• Of course, in a productive environment we always have to test the product. So test implementation is necessary.

• Would ne nice to have a pipeline that automates the building and deployment of the app so it don't need the manual push to docker-hub.
