Integrating Zitadel and ArgoCD

These instructions will take you through the entire process of getting your ArgoCD application authenticating and authorizing with Zitadel. You will create an application within Zitadel and configure ArgoCD to use Zitadel for authentication using roles set in Zitadel to determine privileges in ArgoCD.

The following steps are required to integrate ArgoCD with Zitadel: 1. Create a new project and a new application in Zitadel 2. Configure the application in Zitadel 3. Set up roles in Zitadel 4. Set up an action in Zitadel 5. Configure ArgoCD configmaps 6. Test the setup

The following values will be used in this example: - Zitadel FQDN: - Zitadel Project: argocd-project - Zitadel Application: argocd-application - Zitadel Action: groupsClaim - ArgoCD FQDN: - ArgoCD Administrator Role: argocd_administrators - ArgoCD User Role: argocd_users

You may choose different values in your setup; these are used to keep the guide consistent.

Setting up your project and application in Zitadel

First, we will create a new project within Zitadel. Go to Projects and select Create New Project.
You should now see the following screen.

Zitadel Project

Check the following options: - Assert Roles on Authentication - Check authorization on Authentication

Zitadel Project Settings


Go to Roles and click New. Create the following two roles. Use the specified values below for both fields Key and Group. - argocd_administrators - argocd_users

Your roles should now look like this:

Zitadel Project Roles


Next, go to Authorizations and assign your user the role argocd_administrators. Click New, enter the name of your user and click Continue. Select the role argocd_administrators and click Save.

Your authorizations should now look like this:

Zitadel Project Authorizations

Creating an application

Go to General and create a new application. Name the application argocd-application.

For type of the application, select WEB and click continue.

Zitadel Application Setup Step 1

Select CODE and continue.

Zitadel Application Setup Step 2

Next, we will set up the redirect and post-logout URIs. Set the following values: - Redirect URI: - Post Logout URI:

The post logout URI is optional. In the example setup users will be taken back to the ArgoCD login page after logging out.

Zitadel Application Setup Step 3

Verify your configuration on the next screen and click Create to create the application.

Zitadel Application Setup Step 4

After clicking Create you will be shown the ClientId and the ClientSecret for your application. Make sure to copy the ClientSecret as you will not be able to retrieve it after closing this window.
For our example, the following values are used: - ClientId: 227060711795262483@argocd-project - ClientSecret: UGvTjXVFAQ8EkMv2x4GbPcrEwrJGWZ0sR2KbwHRNfYxeLsDurCiVEpa5bkgW0pl0

Zitadel Application Secrets

Once you have saved the ClientSecret in a safe place, click Close to complete creating the application.

Go to Token Settings and enable the following options:
- User roles inside ID Token - User Info inside ID Token

Zitadel Application Settings

Setting up an action in Zitadel

To include the role of the user in the token issued by Zitadel, we will need to set up a Zitadel Action. The authorization in ArgoCD will be determined by the role contained within the auth token.
Go to Actions, click New and choose groupsClaim as the name of your action.

Paste the following code into the action:

 * sets the roles an additional claim in the token with roles as value an project as key
 * The role claims of the token look like the following:
 * // added by the code below
 * "groups": ["{roleName}", "{roleName}", ...],
 * Flow: Complement token, Triggers: Pre Userinfo creation, Pre access token creation
 * @param ctx
 * @param api
function groupsClaim(ctx, api) {
  if (ctx.v1.user.grants === undefined || ctx.v1.user.grants.count == 0) {

  let grants = [];
  ctx.v1.user.grants.grants.forEach((claim) => {
    claim.roles.forEach((role) => {
  });"groups", grants);

Check Allowed To Fail and click Add to add your action.

Note: If Allowed To Fail is not checked and a user does not have a role assigned, it may be possible that the user is no longer able to log in to Zitadel as the login flow fails when the action fails.

Next, add your action to the Complement Token flow. Select the Complement Token flow from the dropdown and click Add trigger.
Add your action to both triggers Pre Userinfo creation and Pre access token creation.

Your Actions page should now look like the following screenshot:

Zitadel Actions

Configuring the ArgoCD configmaps

Next, we will configure two ArgoCD configmaps: - argocd-cm.yaml - argocd-rbac-cm.yaml

Configure your configmaps as follows while making sure to replace the relevant values such as url, issuer, clientID, clientSecret and logoutURL with ones matching your setup.


apiVersion: v1
kind: ConfigMap
  name: argocd-cm
  namespace: argocd
  labels: argocd
  admin.enabled: "false"
  oidc.config: |
    name: Zitadel
    clientID: 227060711795262483@argocd-project
    clientSecret: UGvTjXVFAQ8EkMv2x4GbPcrEwrJGWZ0sR2KbwHRNfYxeLsDurCiVEpa5bkgW0pl0
      - openid
      - profile
      - email
      - groups


apiVersion: v1
kind: ConfigMap
  name: argocd-rbac-cm
  namespace: argocd
  labels: argocd
  scopes: '[groups]'
  policy.csv: |
    g, argocd_administrators, role:admin
    g, argocd_users, role:readonly
  policy.default: ''

The roles specified under policy.csv must match the roles configured in Zitadel.
The Zitadel role argocd_administrators will be assigned the ArgoCD role admin granting admin access to ArgoCD.
The Zitadel role argocd_users will be assigned the ArgoCD role readonly granting read-only access to ArgoCD.

Deploy your ArgoCD configmaps. ArgoCD and Zitadel should now be set up correctly to allow users to log in to ArgoCD using Zitadel.

Testing the setup

Go to your ArgoCD instance. You should now see the LOG IN WITH ZITADEL button above the usual username/password login.

Zitadel ArgoCD Login

After logging in with your Zitadel user go to User Info. If everything is set up correctly you should now see the group argocd_administrators as shown below.
