Hi, is there a doc or a place to confirm the environment variables of a docker cluster with 2 ingest nodes? I have nodes es01 .. es05. 01 .. 03 are data nodes and master. 04 and 05 are ingest nodes.

Do I need to reference the secondary ingest node in any way? I can't tell from the docs. Below is my docker compose section.

```
es04:
image: docker.elastic.co/elasticsearch/elasticsearch:7.5.1
container_name: es04
restart: unless-stopped
environment:
  - node.name=es04
  - node.master=false
  - node.data=false
  - node.voting_only=false
  - node.ingest=true
  - cluster.name=cluster01
  - discovery.seed_hosts=es01,es02,es03
  - ELASTIC_USERNAME=$ELASTIC_USERNAME
  - ELASTIC_PASSWORD=$ELASTIC_PASSWORD
  - bootstrap.memory_lock=true
  - xpack.license.self_generated.type=basic
  - xpack.security.enabled=true
  - xpack.security.http.ssl.enabled=true
  - xpack.security.http.ssl.key=$CERTS_DIR/es04/es04.key
  - xpack.security.http.ssl.certificate_authorities=$CERTS_DIR/ca/ca.crt
  - xpack.security.http.ssl.certificate=$CERTS_DIR/es04/es04.crt
  - xpack.security.transport.ssl.enabled=true
  - xpack.security.transport.ssl.verification_mode=certificate
  - xpack.security.transport.ssl.certificate_authorities=$CERTS_DIR/ca/ca.crt
  - xpack.security.transport.ssl.certificate=$CERTS_DIR/es04/es04.crt
  - xpack.security.transport.ssl.key=$CERTS_DIR/es04/es04.key
  - "ES_JAVA_OPTS=-Xms1024m -Xmx1024m"
ulimits:
  memlock:
    soft: -1
    hard: -1
```
