Example: How to configure a Continuous Delivery (CD) workflow using Quarkus Helm and ArgoCD
In this example, we’re going to use the REST CRUD application in Quarkus from this example. Then, we’re going to push the Helm chart resources into a GIT repository. Next, we’re going to use the ArgoCD user interface to add a new application and configure it to use the GIT repository where we pushed the generated Helm chart.
Have logged into an ArgoCD instance
Have installed the GIT command line
We’re going to continue with the same REST CRUD application that we created for this example, so if you haven’t seen this example yet, go for it.
After configuring the Quarkus Helm extension, the generated Helm charts will be created at
target/helm/kubernetes/demo folder and usually the
target folder is ignored when pushing changes into GIT, so let’s configure the Quarkus Helm repository to create the Helm charts into another repository.
Now, the Quarkus Helm extension will create the charts into the upper level project folder and will create a
folder directory name.
Next, assuming your project is already a GIT repository, you need to commit this directory and push it:
git add folder
git commit -m "Added folder that contains generated Helm charts"
Finally, let’s go to ArgoCD.
Assuming that you’re configured the ArgoCD project and the destination clusters/namespaces, you need to go to the ArgoCD user interface and click on the "+ NEW APP":
In the next form, set the application name as you wish, the sync policy to automatic and as source and the ArgoCD project.
Next, configure the Source by selecting the URL of your GIT repository and the correct branch. When doing this, ArgoCD will automatically detect the Helm charts that were found. Select the right one in the Path field.
Then, use the cluster URL you configured in the destination.
Moreover, ArgoCD will automatically map the Helm values YAML file into form parameters, so you can easily provide or overwrite any property:
Now, click on "Create" and ArgoCD will automatically display all the resources, the application health and sync status:
