How to combine argo workflow with argo cd?

Question

I would like to deploy Keycloak on my K8S cluster. In addition, the prerequisite for using Keycloack is a database, so I am going to use postgresql.

Before deploying Keycloak, the database has to be up and running. For such as scenario, I think, I should use Argo Workflow .

My question is, how to trigger the ArgoCD, after the database is up and running through the Argo Workflow? Or how to combine Argo Workflow with ArgoCD?

Answer 1

This should be possible without using Argo Workflow to spin up a Postgres server. ArgoCD supports multiple ways to deploy a "package" of resources that includes both Keycloack and Postgres.

For example, you could use Keybase's Helm chart which optionally supports a Postgres component.

Then you can follow ArgoCD's documentation on deploying Helm charts .

While Argo Workflows does help manage sequential tasks, those tasks are usually ephemeral - they execute once and disappear. For a more persistent Postgres server, you want to make it part of your deployment rather than a one-off task.
