• Argo Workflows: Schedule workflows with CronWorkflow

    argo workflows kubernetes cronworkflow schedule cron

    With Argo workflows you can automate tasks like building and pushing Docker images on a regular schedule: You just need to use the CronWorkflow to call any WorkflowTemplate.

    In this example we are going to set up an Argo CronWorkflow that runs every hour, clones a Git repository, builds a Docker image using Kaniko, and pushes it to a Docker registry.

  • What's a kubernetes StatefulSet?

    kubernetes StatefulSet

    When we need to have a stateful application running on Kubernetes, we might need to use a StatefulSet. With a StatefulSet, we can manage stateful applications where each pod needs a stable, unique network identity and storage that persists across pod rescheduling. Unlike Deployments, which focus on maintaining a specified number of replicas, StatefulSets ensure each pod is given a unique ordinal index and retains the same identity throughout its lifecycle. If a pod is deleted or a node fails, the replacement pod will maintain the same identity and storage.

    argo workflows kubernetes exit handler template

    An exit handler is a template that always executes at the end of a workflow (regardless of whether it completed successfully or returned an error). You can use this run any action, for example: to send notifications after a workflow runs, post the status of the workflow to a webhook, clean up artifacts or run another workflow.

    argo workflows kubernetes templates container script resource suspend

    When we are creating a Workflow in Argo Workflows, we need to define the tasks that we need to do. These tasks are defined using templates: They are the building blocks of a Workflow, defining how each task will be executed.

  • Argo Workflows: Passing artifacts in a multi-step WorkflowTemplate

    multi-step argo workflows artifacts

    In a Workflow we'll need to be able to share data between the different steps. To do so we can use the artifacts section in the WorkflowTemplate. This allows us to pass data between steps in a Workflow.
