helm-secrets VS sops-secrets-operator

helm plugin install https://github.com/databus23/helm-diff helm plugin install https://github.com/aslafy-z/helm-git helm plugin install https://github.com/jkroepke/helm-secrets

I use Helm secrets which integrates Mozilla Sops to handle secrets in my Helm charts.

Use Helm Secrets.

ArgoCD users would have to build container images with SOPS baked in using Helm chart extensions or Kustomize extensions. Flux allows configuring sops directly into the Flux manifests.

There is also the helm secrets plugin, which can also be used in ArgoCD with manual configuration.

Not sure if this is applicable for your use case, but you could use helm-secrets to fetch remote value files from https or git: https://github.com/jkroepke/helm-secrets/wiki/Values

$ helm plugin install https://github.com/jkroepke/helm-secrets --version v3.14.0

SOPS is great, and there are a lot of GitOps tools that either integrate with SOPS directly or make it relatively painless to integrate into your workflow, e.g. helm-secrets.

sops-secrets-operator (sops)

There is also a third-party sops-secrets operator available.

I have configured sops-secret-controller too, I'll be using that to manage my secrets. But my problem is that I don't know beforehand the value.

SOPS that was developed by Mozilla offers significantly more options, though at the expense of a more complex configuration. Here, the key material can come from the key management systems (KMS) of the major cloud providers, from your own HashiCorp Vault, or from configured PGP keys. SOPS itself does not contain an operator, but there are different ways to use it with GitOps. Flux v2 offers native support. There is also the helm-secrets plug-in, which can also be used in ArgoCD with the manual configuration. There is also a sops-secrets operator that has been developed by a third party.
