elasticsearchHow do I set up authentication for Elasticsearch?

To set up authentication for Elasticsearch, you need to enable Shield and configure roles and users. Shield is a plugin for Elasticsearch and is available in the X-Pack.

First, you need to install Shield in Elasticsearch. You can do this by running the command:

bin/elasticsearch-plugin install x-pack

This will install the X-Pack in Elasticsearch.

Next, you need to configure roles and users. You can do this by creating a elasticsearch-users.yml file and adding the following code:

admin:
  password: "adminpassword"
  roles: admin

user:
  password: "userpassword"
  roles: user

This will create two users, admin and user, with the respective passwords. The admin user will have the admin role and the user user will have the user role.

Finally, you need to load the elasticsearch-users.yml file into Elasticsearch. You can do this by running the command:

bin/elasticsearch-users useradd -b -c elasticsearch-users.yml

This will load the users and roles into Elasticsearch.

Once you have done this, authentication will be enabled for Elasticsearch.
