Use a commit ID as a parameter on an ArgoCD ApplicationSet

argocd commit id build environment Application

2 min read | by Jordi Prats

When defining ArgoCD Applicacions it can come handy to be able to use it's commit id as a variable. This comes specially handy when using ApplicacionSets

There are several variables we can use (see Build environment), for getting the commit id we can use ARGOCD_APP_REVISION.

For example, if we have a build system that uses the commit id for setting the container tag, we can use the parameters attribute to feed it to the image.tag value of a helm chart as follows:

apiVersion: argoproj.io/v1alpha1 kind: ApplicationSet metadata:  name: pet2cattle-versions  namespace: argocd spec:  generators:  - list:  elements:  - target: 1.0.0  instance: v1  - target: 2.0.0  instance: v2  template:  metadata:  name: pet2cattle-{{ instance }}  spec:  project: default  syncPolicy:  automated:  prune: true  selfHeal: true  syncOptions:  - CreateNamespace=true  source:  repoURL: ssh://git@github.com:jordiprats/helm-pet2cattle.git  path: .  targetRevision: "{{ target }}"  helm:  values: |  ingress:  hosts:  - "{{ instance }}.pet2cattle.com  parameters:  - name: image.tag  value: $ARGOCD_APP_REVISION  destination:  server: https://kubernetes.default.svc  namespace: pet2cattle
