Allow referencing individual fields of a 1password item

[lhriley]

Summary

When writing a OnePasswordItem definition, it would be helpful to reference individual fields of a 1password item rather than the entire item as a whole.

Use cases

For example, consider the setting of certain environment variables across several applications where may have different names, but require the same value.

App 1:

APP1_MY_VAR="foo-bar-baz"

App 2:

APP2_MY_VAR="foo-bar-baz"

Proposed solution

Create a new OnePassword kind (or modify the existing kind: OnePasswordItem) to allow referencing individual fields:

apiVersion: onepassword.com/v1
kind: OnePasswordFields
metadata:
  name: <item_name> #this name will also be used for naming the generated kubernetes secret
spec:
  itemFields:
    <k8s secret key name>: "vaults/<vault_id_or_title>/items/<item_id_or_title>/fields/<field>" 
    APP1_MY_VAR: "vaults/<vault_id_or_title>/items/<item_id_or_title>/fields/<field>" 
    APP2_MY_VAR: "vaults/<vault_id_or_title>/items/<item_id_or_title>/fields/<field>"

For example:

apiVersion: onepassword.com/v1
kind: OnePasswordFields
metadata:
  name: my-secret-app1
spec:
  itemFields:
    APP1_MY_VAR: "vaults/myVault/items/myItem/fields/token"

apiVersion: onepassword.com/v1
kind: OnePasswordFields
metadata:
  name: my-secret-app2
spec:
  itemFields:
    APP2_MY_VAR: "vaults/myVault/items/myItem/fields/token"

would produce the following secrets:

apiVersion: v1
kind: Secret
metadata:
  name: my-secret-app1
  namespace: default
type: Opaque
data:
  APP1_MY_VAR: "foo-bar-baz"

apiVersion: v1
kind: Secret
metadata:
  name: my-secret-app2
  namespace: default
type: Opaque
data:
  APP2_MY_VAR: "foo-bar-baz"

Is there a workaround to accomplish this today?

Not using the onepassword-operator that I'm aware of. You could create multiple secrets from multiple vault items, and then individually reference the secrets created by the operator in each deployment, etc. This would create significant extra code, and be difficult to maintain.

References & Prior Work

None that I'm specifically aware of. This issue is similar, but appears to target mounting multiple items within a single k8s secret: #59

Thanks for your suggestion. We're actually working on a way now that lets you map 1Password item fields to environment variables, so stay tuned!

Any ETA on this?

@florisvdg Do you know if this is still in the roadmap? It seems to be almost a conflict between the 1password client's always showing of the username and password fields and being unable to remap them to other names.

My use case is that i have a username and password for ceph and the ceph helm chart expects the secret to be as userID and userKey.

I just want to highlight that if you want this to be viable against other products this is a nessecary feature. Currently it puts you behind provides such as csi-secrets-store-provider-aws, External Secrets and even Hasicorp vault. They all have this in some way or another.

I've been trying to avoid writing a filtering secret sync operator for weeks hoping I'd stumble across a solution for this problem, but still nothing. The injector allows me to pick out arbitrary items, but requires full-access 1password credentials for each consuming pod. The operator fixes the credential issue, but replaces that problem with making me awkwardly structure 1password entries with duplicated data. 😅 How can I help with a hybrid solution? ;)

[stayanti]

Not being able to control the key of the secret is a showstopper here as well.

I have integrated external-secrets to work with 1password-connect in order to bridge this gap:

Example

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: minio
spec:
  secretStoreRef:
    kind: ClusterSecretStore
    name: onepassword
  refreshInterval: 500h
  target:
    deletionPolicy: Delete
  data:
    - secretKey: MINIO_ROOT_USER
      remoteRef:
        key: aws:minio
        property: access key
    - secretKey: MINIO_ROOT_PASSWORD
      remoteRef:
        key: aws:minio
        property: secret key

Tnx, got a working solution, Adding a label to the onepassword item solved it for me. That way i can control the key of the secret

@stayanti Have you got an example of how you fixed it?
