 Make sure you have Elasticsearch up and running. You can [install](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html) it locally, but the easiest way is to use [Docker](https://www.docker.com/get-started):
 
 ```shell
-$ docker run --rm --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.11.1

+### Security
+
+Please note that starting from version 8 ElasticSearch has security features enabled by default.
+Docker command above has it disabled for local testing convenience.  If you want to enable it, omit
+`"xpack.security.enabled=false"` part from Docker command, and run these command after starting container (container name `es8` assumed):
+
+Reset password for `elastic` user:
+```
+docker container exec es8 '/usr/share/elasticsearch/bin/elasticsearch-reset-password' -u elastic
+```
+
+Extract CA certificate generated by ElasticSearch on first run:
+```
+docker container cp es8:/usr/share/elasticsearch/config/certs/http_ca.crt tmp/

+And then add them to settings:

+```yaml
+# config/chewy.yml

+  user: 'elastic'
+  password: 'SomeLongPassword'
+  transport_options:

 It is also a good idea to set up the `:bypass` strategy inside your test suite and import objects manually only when needed, and use `Chewy.massacre` when needed to flush test ES indices before every example. This will allow you to minimize unnecessary ES requests and reduce overhead.
