Adding more workloads

Now that we've set up the foundation of the App of Apps pattern, we can add the additional workload Helm charts to the Git repository.

The repository structure will look like this after adding the application charts:

.
|-- app-of-apps
|   |-- ...
|-- carts
|   `-- Chart.yaml
|-- catalog
|   `-- Chart.yaml
|-- checkout
|   `-- Chart.yaml
|-- orders
|   `-- Chart.yaml
`-- ui
    `-- Chart.yaml

Let's copy the application chart files to our Git repository directory:

~$cp -R ~/environment/eks-workshop/modules/automation/gitops/argocd/app-charts/* \

~/environment/argocd/

Next, commit and push these changes to the Git repository:

~$git -C ~/environment/argocd add .

~$git -C ~/environment/argocd commit -am "Adding apps charts"

~$git -C ~/environment/argocd push

Sync the apps application:

~$argocd app sync apps

~$argocd app wait -l app.kubernetes.io/created-by=eks-workshop

When Argo CD completes the process, all our applications will be in the Synced state as shown in the ArgoCD UI:

We should now see a set of new namespaces with each application component deployed:

~$kubectl get namespaces

NAME              STATUS   AGE

argocd            Active   18m

carts             Active   28s

catalog           Active   28s

checkout          Active   28s

default           Active   8h

kube-node-lease   Active   8h

kube-public       Active   8h

kube-system       Active   8h

orders            Active   28s

ui                Active   11m

Let's examine one of the deployed workloads more closely. For example, we can check the carts component:

~$kubectl get deployment -n carts

NAME    READY   UP-TO-DATE   AVAILABLE   AGE

carts   1/1     1            1           46s

This confirms that our GitOps-based deployment using the App of Apps pattern has successfully deployed all microservices to our cluster.
