Argo cd

Released

Overview

This module deploys Argo CD, a declarative, GitOps continuous delivery tool for Kubernetes. It sets up the necessary Helm release, configures SSO integration, and exposes the Argo CD server. The module includes OAuth2 configuration for secure access.

Tip

This implementation uses the official Argo CD Helm chart. You can find more details in the Argo CD documentation.

Helm values have been customized from the defaults, and common configuration needs are exposed as variables.

If needed the entire helm chart can be customized by setting the override_helm_values variable.

Compute Requirements

For optimal performance, the following resources are recommended:

1 CPU core
3GB of memory

Argo CD is relatively lightweight compared to other tools, but resource requirements may increase with the number of applications and repositories being managed.

Warning

When using SSO with Google OAuth, make sure to configure the correct redirect URIs in your Google Cloud Console. The redirect URI should be https://your-domain/api/dex/callback.

Local Deployment

Argo CD will start on port 30088 by default.

Production Considerations

Argo CD is licensed under the Apache License 2.0, making it suitable for both personal and commercial use.

It has a built in “Dex” server for OAuth2 authentication. Google OAuth is supported out of the box via variables, other providers can be added by passing in a custom override_helm_values variable.

Examples

Note

All examples omit the configuration for the kubernetes provider and helm provider. You can find more information about how to configure these providers in the usage section.
