BackStore - Backup and Restore PVC Custom k8s Controller

📝 Table of Contents

🧐 About

The BackStore custom kubernetes controller is written primarily in go lang. This controller explicitly keeps a watch on newly created CRs for Backupping and Restoring in all Namespaces,
And as soon as a new CR is created, our controller will create Backup or Restore Data of PVC based on the CR.

🏁 Getting Started

These instructions will get you the project up and running on your local machine for development and testing purposes. See Running the Code for notes on how to deploy the project on a Local System or on a Kubernetes Server.

Prerequisites

To run the BackStore Controller on Local System, first we need to install following Software Dependencies.

Once above Dependencies are installed we can move with further steps

Installing

A step by step series of examples that tell you how to get a development env running.

Step 1: Install Project related Dependencies

go mod tidy

Step 2: Running a 2 Node Mock Kubernetes Server Locally using minikube

minikube start --nodes 2

Step 3: Enable volumesnapshots and csi-hostpath-driver addons:

minikube addons enable volumesnapshots
minikube addons enable csi-hostpath-driver
kubectl create -f manifests/rbac-csi-snapshotter.yaml
kubectl create -f manifests/rbac-external-snapshotter.yaml

Step 4: Setting Up Environmental Variables

Set up the Environmental variables according to your needs. The Application will run with defaults as mentioned in the following table

Environmental Variable Usage Default Values
BACKSTORE_RESTORE_QUEUE Queue for holding Restore CR objects BACKSTORE_RESTORE
BACKSTORE_BACKUP_QUEUE Queue for holding Backup CR objects BACKSTORE_BACKUP

Step 5: Creating MySQL Deployments, PV and PVC

kubectl create -f manifests/mysql-secret.yaml
kubectl create -f manifests/mysql-storage.yaml
kubectl create -f manifests/mysql-deployment.yaml

Step 5: Creating CRDs for Backup and Restore

kubectl create -f manifests/backup-crd.yaml
kubectl create -f manifests/restore-crd.yaml

🔧 Running the Code

To Run the BackStore Controller on local machine, Open a terminal in the Project and run following command

go build

./backstore

Insert Some Data in Mysql PV,PVC

kubectl create -f manifests/backup.yaml

Delete Data from Mysql PV,PVC

kubectl create -f manifests/restore.yaml
