I am running the app search docker and trying to change the worker pool but it nothing happens when I set -e worker.threads=8. When I look at port 3003 is the worker count still 4.

`docker run -ti -p 3003:3003 -p 3002:3002 -e elasticsearch.host=<host> -e elasticsearch.password=<password> -e elasticsearch.username=<username> -e worker.threads=8 docker.elastic.co/app-search/app-search:7.4.0`

Thank you for reporting this issue.  
The `worker.threads` option cannot be configured this way for the docker image. We plan to fix it in the next patch release.  
In the meantime, the only way to configure `worker.threads` is to build a new docker image with a custom app-search.yml.

Example, for app-search.yml:

```auto
allow_es_settings_modification: true
app_search.listen_host: 0.0.0.0
elasticsearch.host: ${elasticsearch.host:"http://elasticsearch:9200"}
elasticsearch.username: ${elasticsearch.username:elastic}
elasticsearch.password: ${elasticsearch.password:changeme}
worker.threads: ${worker.threads:4}

```

If other options need to be passed with `-e`, they will need to be included in app-search.yml.  
In the same directory as app-search.yml, add a Dockerfile:

```auto
FROM docker.elastic.co/app-search/app-search:7.4.0
COPY app-search.yml /usr/share/app-search/config/app-search.yml

```

Build the docker image named `app-search-test`:

```auto
docker build -t app-search-test .

```

Finally, run the container with:

```auto
docker run -ti -p 3003:3003 -p 3002:3002 -e elasticsearch.host=<host> -e elasticsearch.password=<password> -e elasticsearch.username=<username> -e worker.threads=8 app-search-test

```
