The client secret for oidc plugin cannot be configured as environment variable

[supreethmohan]

Current Behavior

I see that client secret for oidc plugin cannot be configured as a environment variable as per documentation. Only few plugins such as key-auth,jwt-auth,basic-auth,authz-keycloak,wolf-rbac support environment varaibles

Expected Behavior

should be able to configure client_secret as environment variable for oidc plugin as well

Error Logs

No response

Steps to Reproduce

1. Configure oidc plugin with client secret as an enviroment variable.
2. configure key-auth plugin with key as an environment variable

Environment

Operating system (run uname -a):
OpenResty / Nginx version (run openresty -V or nginx -V):

Any workaround? I have a use case where I need to pull oidc secret in kubernetes to use in plugin in a route.

Sharing for anyone facing a similar issue:

If you deploy in kubernetes, I found the following is a viable approach and works:

https://apisix.apache.org/docs/ingress-controller/concepts/apisix_route/#config-with-secretref-where-the-secret-data-contains-path-to-a-specific-key-that-needs-to-be-overridden-in-plugin-config

Setting extraEnv in helm chart for APISIX and trying to pull it as $ENV://SECRET does not work.
