📄️ What is Kubernetes?
Kubernetes is a container orchestration platform that can be used to manage containers in the cloud. It is commonly used in microservices architectures to ensure that all the containers are running at any given time, and that the network communication across various containers is taken care of.
📄️ Deploy the backend
As we did with the containers, we will start with the backend. The deployment will create two replicas of our backend.
📄️ Create an ingress
You now have two pods running your backend service, but they aren't accessible from the outside of the cluster. In order for the frontend to connect to it, they will need to be exposed. This is where the ingress will come into play.
📄️ Deploy the frontend
The process to deploy the frontend is very similar to the backend. The two setups being almost identical.
📄️ Set up the ingress for multiple services
At the moment, the ingress is only configured to access the backend. The ingress can support multiple rules to redirect the traffic. In this example, we will use rules based on the request path to redirect the traffic to either the frontend or the backend.
📄️ Deploying the database on Kubernetes
Deploying a database on Kubernetes is no simple task. You will need to add persistence, as well as ensuring that you have redundancy. And as your application grows, you might need to add sharding and more replication. Perhaps you will need to move data to specific geolocated servers to comply with GDPR policies.
