K8S Database Operator

Description

Database backup is an essential part of any disaster recovery plan. Automated tools such as scripts and Kubernetes operators can help streamline the process of backing up your data. Scripts can be used to automate the process of creating and storing backups on a regular schedule. Kubernetes operators can also be used to manage the backup process for databases running in a Kubernetes cluster. These tools can help ensure that your data is always backed up and ready to be restored in the event of a disaster.

Kubernetes Custom Resource Definitions (CRDs) allow users to define and manage custom resources within a Kubernetes cluster. This can simplify the process of managing complex applications by allowing users to define their own custom resources that can be managed using the Kubernetes API. CRDs have a rich history, having evolved from Third Party Resources in earlier versions of Kubernetes. They have become a powerful tool for extending the functionality of Kubernetes and simplifying the management of complex applications.

Getting Started

You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster. Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info shows).

Installing Resources

kubectl apply -f ./config/crd.yaml

Defining Backup Job

In order to proceed, it is necessary to execute the specified commands and initiate a new job utilizing the provided file. Please regard the following command as an example. All disclaimers and responsibilities are at your discretion.

apiVersion: ops.db.io/v1alpha1
kind: Backup
metadata:
  name: chess-app-mysql-s2-2023-05-05-15-47-00
spec:
  type: mysql
  dbConnectionUrl: tcp://user7737:badSissPassw@rd@svc-0067.mysql.local/sampledb

Development

In this project, a Makefile was utilized to automate all processes. It is highly recommended that the established order be followed for optimal results. The Makefile provides a streamlined and efficient method for managing the various tasks required for the project.

Project elimination is also possible through the use of the Makefile. By utilizing the commands provided within the file, team members can easily delegate and manage tasks, ensuring that the project runs smoothly and efficiently.

Running on the cluster

make manifests
make generate
make docker-build
make docker-push
kustomize build config/default > crd.yaml

Using in kubernetes

kubectl apply -f ~/config/crd.yaml

Uninstall CRDs

To delete the CRDs from the cluster:

make uninstall
