Kubernetes Deployment Guide

Prerequisites

• A Kubernetes cluster up and running.
• kubectl configured to interact with your cluster.

Installation Methods

Method 1: Using a Persistent Volume Claim

1. Create a Deployment Manifest

   Save the following YAML as magi-deployment.yaml:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: magi-deployment
   spec:
     replicas: 1
     selector:
       matchLabels:
         app: magi
     template:
       metadata:
         labels:
           app: magi
       spec:
         containers:
           - name: magi
             image: alex-bruun/magi:latest
             volumeMounts:
               - mountPath: /data
                 name: magi-data
         volumes:
           - name: magi-data
             persistentVolumeClaim:
             claimName: magi-pvc
   

2. Create a Persistent Volume Claim

   Save the following YAML as magi-pvc.yaml:

   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: magi-pvc
   spec:
     accessModes:
       - ReadWriteOnce
     resources:
     requests:
       storage: 1Gi
   

3. Apply the Manifests

   Apply the Persistent Volume Claim and the Deployment manifest:

   kubectl apply -f magi-pvc.yaml
   kubectl apply -f magi-deployment.yaml
   

4. Verify Deployment

   Check the status of the deployment:

   kubectl get pods
   

   Ensure that the pods are running and the volume is mounted correctly.

Method 2: Mounting a Host Path

1. Create a Deployment Manifest

   Save the following YAML as magi-deployment-hostpath.yaml:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: magi-deployment
   spec:
     replicas: 1
     selector:
       matchLabels:
         app: magi
     template:
       metadata:
         labels:
           app: magi
       spec:
         containers:
           - name: magi
             image: alex-bruun/magi:latest
             volumeMounts:
             - mountPath: /data
               name: magi-data
         volumes:
           - name: magi-data
             hostPath:
             path: /path/on/host
             type: Directory
   

   Replace /path/on/host with the actual path on the host machine that you want to mount inside the container.

2. Apply the Manifest

   Apply the deployment manifest:

   kubectl apply -f magi-deployment-hostpath.yaml
   

3. Verify Deployment

   Check the status of the deployment:

   kubectl get pods
   

   Ensure that the pods are running and the host path is mounted correctly.
