Managing Secrets in ArgoCD Without Fighting It

Managing secrets in ArgoCD presents challenges due to its GitOps model, which requires all configurations, including Kubernetes secrets, to be stored in Git. This poses a security risk as secrets can be exposed in plaintext. Encryption methods like SOPS and Sealed Secrets can be used to keep secrets out of plaintext but add operational burdens such as key management and manual encryption processes. Alternatively, using a centralized secrets manager like Infisical, with its Kubernetes Operator, allows secrets to be stored and managed outside of Git, providing a more streamlined and scalable approach. This method involves fetching secrets from an external store and integrating them into Kubernetes as native secret resources, offering centralized control and the ability to update secrets without modifying ArgoCD's source of truth. However, this approach requires careful management of owner references to prevent ArgoCD from pruning these secrets. Overall, while encryption methods can work for simpler setups, centralized secrets management is preferable for more complex environments, offering enhanced security and efficiency.
