Deploy the Gitea/Gitea:1.15 Docker Image on Kubernetes With TypeScript.

Introduction

In this guide, we will deploy the gitea/gitea:1.15 Docker image on a Kubernetes cluster using Pulumi with TypeScript. Gitea is a lightweight Git service, and we will use Kubernetes resources such as Deployments, Services, and PersistentVolumeClaims to manage its deployment.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

1. Initialize a new Pulumi project:

   pulumi new typescript
   

2. Install the necessary Pulumi packages:

   npm install @pulumi/pulumi @pulumi/kubernetes
   

Step 2: Define Kubernetes Resources

1. Create a new file index.ts and import the required packages:

   import * as pulumi from "@pulumi/pulumi";
   import * as k8s from "@pulumi/kubernetes";
   

2. Define a PersistentVolumeClaim for Gitea’s data storage:

   const pvc = new k8s.core.v1.PersistentVolumeClaim("gitea-pvc", {
       metadata: { name: "gitea-pvc" },
       spec: {
           accessModes: ["ReadWriteOnce"],
           resources: { requests: { storage: "10Gi" } },
       },
   });
   

3. Create a Deployment for the Gitea application:

   const appLabels = { app: "gitea" };
   const deployment = new k8s.apps.v1.Deployment("gitea-deployment", {
       metadata: { name: "gitea" },
       spec: {
           selector: { matchLabels: appLabels },
           replicas: 1,
           template: {
               metadata: { labels: appLabels },
               spec: {
                   containers: [{
                       name: "gitea",
                       image: "gitea/gitea:1.15",
                       ports: [{ containerPort: 3000 }],
                       volumeMounts: [{
                           mountPath: "/data",
                           name: "gitea-data",
                       }],
                   }],
                   volumes: [{
                       name: "gitea-data",
                       persistentVolumeClaim: { claimName: pvc.metadata.name },
                   }],
               },
           },
       },
   });
   

4. Expose the Gitea service using a LoadBalancer Service:

   const service = new k8s.core.v1.Service("gitea-service", {
       metadata: { name: "gitea" },
       spec: {
           type: "LoadBalancer",
           selector: appLabels,
           ports: [{ port: 80, targetPort: 3000 }],
       },
   });
   

Step 3: Deploy the Resources

1. Run pulumi up to deploy the resources to your Kubernetes cluster:

   pulumi up
   

Conclusion

In this guide, we have successfully deployed the gitea/gitea:1.15 Docker image on a Kubernetes cluster using Pulumi with TypeScript. We created a PersistentVolumeClaim for data storage, a Deployment for the Gitea application, and a LoadBalancer Service to expose the application. Pulumi makes it easy to manage and deploy cloud resources using familiar programming languages.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Define a PersistentVolumeClaim for Gitea's data storage
const pvc = new k8s.core.v1.PersistentVolumeClaim("gitea-pvc", {
    metadata: { name: "gitea-pvc" },
    spec: {
        accessModes: ["ReadWriteOnce"],
        resources: { requests: { storage: "10Gi" } },
    },
});

// Define labels for the Gitea application
const appLabels = { app: "gitea" };

// Create a Deployment for the Gitea application
const deployment = new k8s.apps.v1.Deployment("gitea-deployment", {
    metadata: { name: "gitea" },
    spec: {
        selector: { matchLabels: appLabels },
        replicas: 1,
        template: {
            metadata: { labels: appLabels },
            spec: {
                containers: [{
                    name: "gitea",
                    image: "gitea/gitea:1.15",
                    ports: [{ containerPort: 3000 }],
                    volumeMounts: [{
                        mountPath: "/data",
                        name: "gitea-data",
                    }],
                }],
                volumes: [{
                    name: "gitea-data",
                    persistentVolumeClaim: { claimName: pvc.metadata.name },
                }],
            },
        },
    },
});

// Expose the Gitea service using a LoadBalancer Service
const service = new k8s.core.v1.Service("gitea-service", {
    metadata: { name: "gitea" },
    spec: {
        type: "LoadBalancer",
        selector: appLabels,
        ports: [{ port: 80, targetPort: 3000 }],
    },
});
