### Kubernetes Ingress Path Explained
#### Introduction
In Kubernetes, Ingress is an API object that manages external access to services within a cluster. By using Ingress, you can define routing rules to map external HTTP/S traffic to internal services based on the request path.
#### Steps to Implement "k8s ingress path"
Below are the steps to implement "k8s ingress path" in Kubernetes:
| Step | Description |
|------|-------------|
| 1 | Create a Kubernetes deployment for your application |
| 2 | Expose the deployment using a Kubernetes service |
| 3 | Create an Ingress resource to route incoming traffic based on paths |
#### Step 1: Create a Kubernetes deployment
First, you need to create a deployment for your application. Here is an example YAML manifest for a simple deployment:
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: myapp-deployment
spec:
replicas: 3
selector:
matchLabels:
app: myapp
template:
metadata:
labels:
app: myapp
spec:
containers:
- name: myapp-container
image: nginx:latest
ports:
- containerPort: 80
```
Apply the above manifest using the command:
```bash
kubectl apply -f deployment.yaml
```
#### Step 2: Expose the deployment using a Kubernetes service
Next, create a service to expose the deployment within the cluster. Below is an example YAML manifest for a service:
```yaml
apiVersion: v1
kind: Service
metadata:
name: myapp-service
spec:
selector:
app: myapp
ports:
- protocol: TCP
port: 80
targetPort: 80
```
Apply the above manifest using the command:
```bash
kubectl apply -f service.yaml
```
#### Step 3: Create an Ingress resource for routing
Now, create an Ingress resource to define routing rules based on paths. Here is an example YAML manifest for an Ingress resource:
```yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: myapp-ingress
spec:
rules:
- host: myapp.com
http:
paths:
- path: /app1
pathType: Prefix
backend:
service:
name: myapp-service
port:
number: 80
```
Apply the above manifest using the command:
```bash
kubectl apply -f ingress.yaml
```
In the above Ingress manifest, the path `/app1` is routed to the `myapp-service` on port 80. You can define multiple paths and backends within the same Ingress resource.
After applying the Ingress manifest, you should be able to access your application at `myapp.com/app1`.
#### Conclusion
In this article, we have discussed how to implement "k8s ingress path" in Kubernetes by creating a deployment, exposing it using a service, and defining routing rules with an Ingress resource. By following these steps, you can efficiently manage external access to your services within a Kubernetes cluster based on the requested paths.

Now, create an Ingress resource to define routing rules based on paths. Here is an example YAML manifest for an Ingress resource:
```yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: myapp-ingress
spec:
rules:
- host: myapp.com
http:
paths:
- path: /app1
pathType: Prefix
backend:
service:
name: myapp-service
port:
number: 80
```
Apply the above manifest using the command:
```bash
kubectl apply -f ingress.yaml
```
In the above Ingress manifest, the path `/app1` is routed to the `myapp-service` on port 80. You can define multiple paths and backends within the same Ingress resource.
After applying the Ingress manifest, you should be able to access your application at `myapp.com/app1`.
