USER To let you set the database username that has access to take a dump of the previous mentioned database. This is used in the MySQL script for taking database dump/backup. The example manifest file creates a CronJob that deploys a simple “Hello” script once a minute. DATABASE To specify which database is to be backed up. ![]() Like other Kubernetes resources, CronJobs are defined in a manifest file. npm install node-cron npm install moment (only for file name formatting) app.js (the file that you serve your Node App) const cron require ('node-cron') const moment require ('moment') const fs require ('fs') const spawn require ('childprocess').spawn // You can adjust the backup frequency as you like, this case will run once a day. It produces SQL statements that can be used to recreate. Put this above in a file and have your cron job point to it: /bin/bash /bin/mail -s 'test subject' 'yournameyourdomain' < /dev/null. To mention the password of the database user that you chose to provide in the previous variable. To let you set the database username that has access to take a dump of the previous mentioned database. To follow along, ensure you use the How to Install Drupal with Linode Kubernetes Engine guide to deploy your own Drupal site. mysqldump is a command-line utility that is used to generate the logical backup of the MySQL database. First try sending only email from the cron job to see if you are getting it to even run. To specify which database is to be backed up. This guide uses a Drupal website deployed with LKE to demonstrate how to back up a MySQL database. Are my paths incorrect Also, the following line I'm not sure will output errors to the dump. To deploy a Linode Kubernetes Engine (LKE) cluster, see our Deploy and Manage a Cluster with Linode Kubernetes Engine guide.Īfter deploying your Kubernetes cluster, make sure your local environment has kubectl installed, and you can access your cluster using kubectl. Cron job: 32 18 /db-backup/mysqldump.sh The problem I am having is the job is not executing through cron or when I am not in the directory. Before You BeginĮnsure you have deployed a Kubernetes cluster. You also learn how to generate automatic daily backups for a Drupal website using Kubernetes CronJobs. In this guide, you learn the syntax for creating Kubernetes CronJobs. You should probably write a bash script instead of using PHP. First, you would follow the instructions from this stackoverflow answer to set up the more-secure mysql login method for command line scripts. If you are not familiar with cron, you can refer to our Schedule Tasks with Cron guide. First, I recommend you upgrade to mysql 5.6+ so that you can keep your database passwords more secure. CronJobs use the same scheduling syntax as cron and crontab, which are standard Linux utilities. Kubernetes (K8s) includes the capability to schedule jobs to run at a particular time with CronJobs. If you are not familiar with Kubernetes, read our Beginner’s Guide to Kubernetes. Linode Kubernetes Engine (LKE) is an open source container orchestration system that helps deploy and manage containerized applications. ![]()
