I want to find a simple example of JWT based authentication for Elasticsearch with docker. I am using the the docker-compose.yml file provided by Elastic here at: > **[Install Elasticsearch with Docker | Elasticsearch Guide \[7.17\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/docker.html#docker-compose-file)** Is there a resource where I can set that up with the minimal settings required, I can use ruby based JWT to create the tokens. ---

Hello, thanks for reaching out, I updated the tags since the `Elastic Security` references the "Elastic Security Solution" questions, this is an `Elasticsearch` question. I'll forward it to the correct team. ---

Hi, First of all JWT authn is not available in version 7.17. I recommend you go with version 8.12. Secondly, docker/docker compose configuration is only tangential to (JWT) authn realm configuration (i.e. if you get to a JWT configuration that works for a single node cluster, launched under the env your most familar with, it should efortlessly translate to the docker compose setup). Here are the docs explaining JWT configuration: [JWT authentication | Elasticsearch Guide [8.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/jwt-auth-realm.html#jwt-realm-configuration) JWT realm configuration is very versatile. You can also take inspiration from integration tests we use on our CI: [elasticsearch/x-pack/qa/oidc-op-tests/src/javaRestTest/java/org/elasticsearch/xpack/security/authc/oidc/C2IdOpTestCase.java at fca3fc82beda930e75d147331dce4dbfdc546e61 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/blob/fca3fc82beda930e75d147331dce4dbfdc546e61/x-pack/qa/oidc-op-tests/src/javaRestTest/java/org/elasticsearch/xpack/security/authc/oidc/C2IdOpTestCase.java#L82) ---

Hi Albert thanks for the tip. I did indeed try with 8.11.4 with a simple elasticsearch instance and without docker. I used the information provided by the documentation but had no success. I get the following error when starting up elasticsearch: ```auto fatal exception while booting Elasticsearchjava.lang.IllegalStateException: security initialization failed at org.elasticsearch.security@8.11.4/org.elasticsearch.xpack.security.Security.createComponents(Security.java:656) at org.elasticsearch.server@8.11.4/org.elasticsearch.node.Node.lambda$new$17(Node.java:759) at org.elasticsearch.server@8.11.4/org.elasticsearch.plugins.PluginsService.lambda$flatMap$1(PluginsService.java:263) at java.base/java.util.stream.ReferencePipeline$7$1.accept(ReferencePipeline.java:273) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:197) ``` Im sure im missing something, thats why I was looking for a resource where I could following a step by step guide to add JWT to elasticsearch ---

Hi Lasra, The snipped doesn't contain enough information to help with diagnosing. Can you paste the full stack trace? In any case, the immediate problem doesn't look JWT-related (given the truncated stack trace you've shared). ---

Hi Albert, thanks for the help but turns out that the endpoint to use JWT authentication with DLS for Connectors was supposed to be the enterprisesearch endpoint and not the elasticsearch endpoint. I assumed since API key authentication with DLS for connectors works with elasticsearch, it was supposed to be the same for JWT. My problem is now solved. ---
