Reset default admin password

I’m new to open distro for elasticsearch and trying to run it on the Kubernetes cluster. After deploying the cluster, I need to change the password for admin user.

I went through this post - default-password-reset

I came to know that, to change the password I need to do the following steps:

  • exec in one of the master nodes
  • generate a hash for the new password using /usr/share/elasticsearch/plugins/opendistro_security/tools/hash.sh script
  • update /usr/share/elasticsearch/plugins/opendistro_security/securityconfig/internal_users.yml with the new hash
  • run /usr/share/elasticsearch/plugins/opendistro_security/tools/securityadmin.sh with parameters

Questions:

  • Is there any way to set those (via env or elasticsearch.yml) during bootstrapping the cluster?
