Kube.netes Elasticsearch 8.5.3 Statefulset（非ECK）设置用户名/密码

Question

How to automatically setup the password of the default user elastic and add other username/password for Elasticsearch 8.5.3 running on kube.netes cluster with manifests? I am not using ECK. Setting environment variable ELASTIC_PASSWORD doesn't work.

As mentioned in the document :

The elasticsearch-setup-passwords tool is deprecated and will be removed in a future release.

You can manually reset the password for the built-in users (including the elastic user), use the elasticsearch-reset-password tool , the Elasticsearch change password API, or the User Management features in Kibana. The elasticsearch-setup-passwords command sets the passwords for the built-in users.

bin/elasticsearch-setup-passwords auto|interactive
[-b, --batch] [-h, --help] [-E <KeyValuePair>]
[-s, --silent] [-u, --url "<URL>"] [-v, --verbose]

When you install Elasticsearch, if the elastic user does not already have a password, it uses a default bootstrap password. The bootstrap password is a transient password that enables you to run the tools that set all the built-in user passwords.

By default, the bootstrap password is derived from a randomized keystore.seed setting, which is added to the keystore during installation. You do not need to know or change this bootstrap password. If you have defined a bootstrap.password setting in the keystore, however, that value is used instead.
