Table of Contents

• Objective
• Step 1 - Adding to our ConfigMap
• Step 2 - Adding a PostSync Job

Objective

• Understand how to add a postsync job
• Configure what workflow to run

Step 1 - Adding to our ConfigMap

Following the idea from above, we’re going to create another set of a job and configmap, however, this time we’ll only specify what automation we want to run, and set the job to happen after everything else has been synced.

First, our configmap - simply add this to the bottom of the existing configmap.yaml file in the templates/ directory:

---
apiVersion: v1
kind: ConfigMap
metadata:
  name: network-automation-to-run-configmap
data:
  controller-configuration.yaml: |
    # Replace with your information!
    controller_hostname: REPLACE_WITH_CONTROLLER_URL_FROM_STUDENT_PAGE
    controller_username: REPLACE_WITH_CONTROLLER_USERNAME
    controller_password: REPLACE_WITH_CONTROLLER_PASSWORD
    controller_validate_certs: 'false'
    
    # If not Team 1, replace with your team number
    controller_workflow_launch_jobs:
      - name: Run Network Automation
        organization: Team 1

Note:

Team1 is used as an example here, replace with your team number

Step 2 - Adding a PostSync Job

Then, add the following to the job.yaml file created earlier:

---
apiVersion: batch/v1
kind: Job
metadata:
  generateName: run-network-automation-
  annotations:
    argocd.argoproj.io/hook: PostSync
spec:
  template:
    spec:
      containers:
        - name: launch-network-automation
          image: quay.io/device-edge-workshops/configure-controller:latest
          volumeMounts:
            - name: automation-to-run-vars
              mountPath: /runner/variables
            - name: tmp
              mountPath: /tmp
      restartPolicy: Never
      volumes:
        - name: automation-to-run-vars
          configMap:
            name: network-automation-to-run-configmap
        - name: tmp
          emptyDir:
            sizeLimit: 100Mi

Ensure everything has been saved/committed/pushed before continuing.
