We’re using https://github.com/argoproj-labs/argocd-vault-plugin which allows you to define secrets in git (works with more backends than just hashicorp vault despite the name). The documentation took me a bit to figure out, but so far it works.

Argo CD Vault plugin

I used argocd vault plugin https://github.com/IBM/argocd-vault-plugin

To install Vault we will use the official Helm chart provided by HashiCorp. For simplicity, install it in developer mode. In dev mode, Vault doesn't need to be initialized or unsealed, but remember, it's only for development or experimentation. Never, ever run a dev mode in production

Once the above steps are done, it's time to install the HashiCorp Vault. The recommended way to deploy a Vault in the Kubernetes cluster is using the Vault’s official Helm chart. To deploy Vault in HA with auto unsealing use the below-mentioned values.yml file.

Yup. There's an official Hashi chart.
