+# Elasticsearch Serverless Resources
+The resources in this directory are used for seeding Elasticsearch Serverless (ESS) images with users, roles and tokens for SSL and authentication. ESS requires file realm authentication, so we will bind mount them into the containers at `/usr/share/elasticsearch/config/`.
+
+## Users
+
+### Default user
+
+The default superuser authentication to login to Kibana is:
+
+```
+username: elastic_serverless
+password: changeme
+```
+
+### Adding users
+
+1. Add the user:encrypted_password to `users` file. The encrypted password for `elastic_serverless` is `changeme` if you want to reuse the value.
+1. Set the new user's roles in `users_roles` file.
+1. Add the username to `operator_users.yml` in the array for file realm users.
+
+
+## Service Account and Tokens
+
+This section for Service Accounts was originally from the [ESS repository](https://github.com/elastic/elasticsearch-serverless/blob/main/serverless-build-tools/src/main/resources/README.service_tokens.md).
+
+The "service_tokens" file contains this line:
+```
+elastic/kibana/kibana-dev:$2a$10$mY2RuGROhk56vLNh.Mgwue98BnkdQPlTR.yGh38ao5jhPJobvuBCq
+```
+
+That line defines a single service token
+- For the `elastic/kibana` service account
+- The token is named `kibana-dev`
+- The token's secret is hashed using bcrypt (`$2a$`) using `10` rounds
+
+Although Elasticsearch used PBKDF2_STRETCH by default, the k8s controller
+creates tokens using bcrypt, so we mimic that here.
+
+The hash is not reversible, so this README is here to tell you what the secret is.
+The secret value is: `UUUUUULK-* Z4`
+That produces an encoded token of: `AAEAAWVsYXN0aWMva2liYW5hL2tpYmFuYS1kZXY6VVVVVVVVTEstKiBaNA`
+Yes, the secret was specially chosen to produce an encoded value that can be more easily recognised in development.
+
+If a node is configured to use this `service_tokens` file, then you can authenticate to it with
+```
+curl -H "Authorization: Bearer AAEAAWVsYXN0aWMva2liYW5hL2tpYmFuYS1kZXY6VVVVVVVVTEstKiBaNA" http://localhost:9200/_security/_authenticate
+```
+
+The name of the token (`kibana-dev`) is important because the `operator_users.yml` file designates that token as an operator and allows us to seed an ESS cluster with this token.
