Part 3: Sync Workload

This is Part 3 of a multi-part, self-paced quick start exercise.

What Will You Do

In part 3, you will test bidrectional syncing of a workload. You will then update the workload manifest in the Git repository and see it automatically applied on the cluster.

Step 1: Update workload From Git

In this step, we will update the workload in the Git repository and then witness the update being applied automatically on the cluster.

  • Navigate to your Git repo -> "projects/defaultproject/workloads/Workload Name.yaml"
  • Edit the workload YAML file
  • Update the version from "Workload Name.-v1" to "Workload Name.-v2"
  • Commit the changes to your Git repository
  • Navigate to your Git repo -> "projects/defaultproject/workloads/artifacts/Workload Name.yaml"
  • Edit the workload YAML file
  • Update the replica count from "2" to "4"
  • Commit the changes to your Git repository

The update will trigger the Gitops pipeline and it will automatically update the running workload.

  • Navigate to Infrastructure -> Clusters
  • Click "Kubectl" for your cluster
  • Type the following Kubectl command 
kubectl get po -n nginx

You should see something like the following:

nginx-deployment-6d8787d7d-6jb5p   1/1     Running   0          55m
nginx-deployment-6d8787d7d-dngpw   1/1     Running   0          55m
nginx-deployment-6d8787d7d-dv5bn   1/1     Running   0          73m
nginx-deployment-6d8787d7d-hffp9   1/1     Running   0          55m

Step 2: Update Workload From System

In this step, we will update the workload from the system and then witness the update being applied automatically in the Git repository.

  • Navigate to Applications -> Workloads
  • Click on your NGINX workload
  • Click "Edit"
  • Update the replica count from "2" to "3"
  • Click "Update"
  • Click "Save And Go To Placement"
  • Click Save And Go To Publish"
  • Click "Republish"

The update will trigger the GitOps pipeline and it will automatically update the workload application spec file in the Git repository.

  • Navigate to your Git repo -> "projects/defaultproject/workloads/artifacts/Workload Name"
  • View the updated workload spec file showing the updated version

Git Workload

Recap

In this part, you tested two-way, bidirectional syncronization between the system and your Git repository for workloads.
