Deploying the User Service with Kubernetes on Your DomainIndia Dedicated Server
This stage involves writing a Kubernetes Deployment manifest and deploying your service to Kubernetes on your DomainIndia dedicated server. Here's how to go about it:
4.1 Writing a Kubernetes Deployment Manifest
A Kubernetes Deployment manifest is a YAML or JSON file that defines the desired state for your application or microservice in the Kubernetes cluster. This file can define a multitude of parameters, but at minimum, you should specify the number of replicas, the container image to use, and the ports to expose.
Here's an example of what this manifest might look like for a hypothetical User Service:
apiVersion: apps/v1
kind: Deployment
metadata:
name: user-service
spec:
replicas: 3
selector:
matchLabels:
app: user-service
template:
metadata:
labels:
app: user-service
spec:
containers:
- name: user-service
image: yourusername/user-service:v1
ports:
- containerPort: 8080
Replace "yourusername/user-service:v1" with the name of the Docker image for your User Service. Also, adjust the number of replicas and the exposed port to fit your requirements.
4.2 Deploying the Service
After writing the Kubernetes Deployment manifest, save it to a file (for example, user-service-deployment.yaml).
Next, deploy your service to Kubernetes by running the following command in the terminal:
kubectl apply -f user-service-deployment.yaml
The kubectl apply command will instruct Kubernetes to set up the deployment as per the configuration defined in your manifest file.
To verify that the deployment was successful, use the following command:
kubectl get deployments
This command will list all deployments in your current namespace. You should see your user-service Deployment listed, along with the number of replicas and their current status.
Congratulations! You have now deployed your User Service to Kubernetes on your DomainIndia dedicated server. The next steps involve managing and monitoring your service to ensure smooth operations. Stay tuned!
