In this section, you can find the guidelines about how to create and manage CronJobs using Console.
A CronJob is a scheduled Job that will be executed periodically on a given schedule. For example, you can use CronJobs to conduct repeated tasks like sending emails, running backups or automating system maintenance. A CronJob doesn not expose API as a microservices does.
Each Job creates one or more Pods and guarantee that a specified number of them successfully terminate.
To learn more about CronJobs, you can find more information on Kubernetes website.
With Console, when you create a CronJob, you are creating Jobs which configures Pods in Kubernetes on a time-based schedule.
To manage CronJobs, Mia-Platform's Console offers a specific section, CronJobs, in the Design area:
In this section, you can create your own CronJob with the create button in the menu or in the placeholder.
In the creation section, you are required to insert the following information:
Name (mandatory): This is the label that you attribute to your CronJob.
Description (optional): This is the description of your CronJob.
Docker Image (mandatory): Insert the name of the docker image that you want to create.
CronJob schedule (mandatory): This is the scheduling time. You can insert here a CronTab expression by following these examples.
After the creation of a CronJob, you will be redirected to the CronJob detail where a yaml file is filled with the information provided during the creation:
Once you have created your CronJob, you can manage it by editing directly its advanced file. The benefits of creating an advanced CronJob are disclosed on Kubernetes website.
You can delete a CronJob with the delete button at the bottom of the page. To confirm the deletion, you have to insert the correct name of the Cronjob in the specific field.
By eliminating a CronJob on Console, you are deleting the image on the Console, but not the Pods on Kubernetes and the configuration on Git provider. This implies that, if you delete the Pods on Kubernetes, but not the Git configuration, you will find again your CronJob at the next deploy.
