How to Enforce Sync Order in ArgoCD app of apps pattern?

[fjammes]

I'm using the app of apps pattern in ArgoCD and I'm looking for a way to enforce a sync order between certain apps. Specifically, I want the strimzi app to be synced before my app containing the Kafka CR, and the minio-operator app to be synced before my app containing the Minio CR.

Is there an easy way to manage dependencies or sync order between apps in ArgoCD?

Here is a link to my argoCD configuration: https://github.com/astrolabsoftware/fink-cd/tree/v3.1.3-rc1/apps/templates

Thanks in advance!

Since you are using Apps of Apps, have you tried sync waves?

[fjammes]

I tried SyncPhases but it seems it works only inside an app, not for synchronizing multiple apps between them. I suppose this is the same thing for sync waves?

If you are using Apps of Apps, you can use SyncWaves in the "first App". Eg, what is described here.

You probably also want to try https://argo-cd.readthedocs.io/en/stable/operator-manual/applicationset/Progressive-Syncs/
It uses application set, but it should help you achieve what you need

I would recommend using SyncWave. Lowest value syncs first.

App 1: argocd.argoproj.io/sync-wave: "100"
App 2: argocd.argoproj.io/sync-wave: "200"

You need to make Argo CD aware of App dependencies as described here https://codefresh.io/blog/argo-cd-application-dependencies/
