Is there any upgrade guide to version 2.12.0+ from earlier version with default admin password?

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
Opensearch 2.13.0 (Helm chart 2.19.0)

Describe the issue:
I am using opensearch in k8s clsuter.

I installed opensearch cluster with chart version 2.19.0 - same version opensearch 2.13.0

I tried to set environment variable with helm value extraEnvs to set default admin user password, I met this error.

Exception updating the admin password : Unable to update the internal users file with the hashed password.

Can anyone give me a guide for setting or skipping to set this default password?
or compatible method with hashed password for initialization?

  • I don’t want to disable securityConfig because I touched internal_user.yml and security_config.yml to set SAML authentication.

Configuration:

  • Statefulset configuration (master, data node same)
env:
  - name: OPENSEARCH_INITIAL_ADMIN_PASSWORD
