Streamline Your Workflow: Automate Backup and Recovery with AWS and Kubernetes

Project: Automate Backup and Recovery Process

Step 1: Create an AWS Account and Set up AWS Backup

• Go to the AWS website and create an account if you don't already have one.

• Log in to the AWS Management Console and navigate to the AWS Backup dashboard.

• Click on "Create a backup vault" and follow the instructions to create a new backup vault.

• Note down the backup vault name and ARN, we'll need it later.

Step 2: Create a Kubernetes Cluster

• Go to the AWS Management Console and navigate to the Amazon Elastic Container Service for Kubernetes (EKS) dashboard.

• Click on "Create a cluster" and follow the instructions to create a new EKS cluster.

• Choose the desired instance type and number of instances for your cluster.

• Note down the cluster name and ARN, we'll need it later.

Step 3: Create a Docker Image

• Create a new directory for your project and navigate to it in your terminal.

• Create a new file called Dockerfile with the following contents:

dockerfileVerifyOpen In EditorEditCopy code1FROM ubuntu:latest
2
3# Install necessary packages
4RUN apt-get update && apt-get install -y awscli
5
6# Copy the backup script
7COPY backup.sh /backup.sh
8
9# Make the script executable
10RUN chmod +x /backup.sh
11
12# Run the script when the container starts
13CMD ["/backup.sh"]

• Create a new file called backup.sh with the following contents:

bashVerifyOpen In EditorEditCopy code1#!/bin/bash
2
3# Set the backup vault name and ARN
4VAULT_NAME="my-backup-vault"
5VAULT_ARN="arn:aws:backup:us-west-2:123456789012:vault:my-backup-vault"
6
7# Set the Kubernetes cluster name and ARN
8CLUSTER_NAME="my-eks-cluster"
9CLUSTER_ARN="arn:aws:eks:us-west-2:123456789012:cluster/my-eks-cluster"
10
11# Create a new backup job
12aws backup create-backup-job --vault-name $VAULT_NAME --resource-arn $CLUSTER_ARN --backup-vault-id $VAULT_ARN

• Build the Docker image by running the command docker build -t my-backup-image .

Step 4: Create a Kubernetes Deployment

• Create a new file called deployment.yaml with the following contents:

yamlVerifyOpen In EditorEditCopy code1apiVersion: apps/v1
2kind: Deployment
3metadata:
4  name: my-backup-deployment
5spec:
6  replicas: 1
7  selector:
8    matchLabels:
9      app: my-backup-app
10  template:
11    metadata:
12      labels:
13        app: my-backup-app
14    spec:
15      containers:
16      - name: my-backup-container
17        image: my-backup-image:latest
18        command: ["/backup.sh"]

• Apply the deployment to your Kubernetes cluster by running the command kubectl apply -f deployment.yaml

Step 5: Schedule the Backup Job

• Create a new file called cronjob.yaml with the following contents:

yamlVerifyOpen In EditorEditCopy code1apiVersion: batch/v1
2kind: CronJob
3metadata:
4  name: my-backup-cronjob
5spec:
6  schedule:
7    - cron: 0 0 * * *
8  jobTemplate:
9    spec:
10      template:
11        spec:
12          containers:
13          - name: my-backup-container
14            image: my-backup-image:latest
15            command: ["/backup.sh"]
16          restartPolicy: OnFailure

• Apply the cron job to your Kubernetes cluster by running the command kubectl apply -f cronjob.yaml

Step 6: Verify the Backup

• Wait for the cron job to run and verify that a new backup has been created in your AWS Backup vault.

• You can check the backup status by running the command aws backup describe-backup-job --backup-job-id <backup-job-id>
