   Hi, here is a simple docker-compose example using search plugin without any hack, just standard compose yaml.
   
   ```shell
   mkdir -p ./config/{couchdb,clouseau}
   ```
   
   **./config/clouseau/clouseau.ini**
   ```ini
   [clouseau]
   name=clouseau@127.0.0.1
   cookie=monster
   dir=/data
   max_indexes_open=500
   ```
   
   **./config/clouseau/log4j.properties**
   ```
   log4j.rootLogger=debug, CONSOLE
   log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
   log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
   log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %c [%p] %m%n
   ```
   
   **./config/couchdb/local.ini**
   ```ini
   [couch_httpd_auth]
   secret = dev
   
   [admins]
   ; admin = admin
   admin = -pbkdf2-37aa363808ec5b83fc71cf2811479fbf1917f43d,2483e8ffe206819712f3bd1ba2308d41,10
   ```
   
   ```shell
   curl -sSL -o clouseau-2.17.0-dist.zip "https://github.com/cloudant-labs/clouseau/releases/download/2.17.0/clouseau-2.17.0-dist.zip
   ```
   Unizp clouseau-2.17.0-dist.zip in clouseau-2.17.0 
   
   **docker-compose.yml**
   This yaml expose 5984 to the host network, if you already using the 5984 change it on the yaml
   ```yaml
   version: '3.8'
   services:
     couchdb1:
       image: couchdb:3.1.0
       restart: always
       ports:
       - 5984:5984
       environment:
         - NODENAME=10.0.0.10
         - ERL_FLAGS=-setcookie monster
       volumes:
       - ./config/couchdb:/opt/couchdb/etc/local.d
       - ./data/couchdb/1:/opt/couchdb/data
       networks:
         couchdb-net:
           ipv4_address: 10.0.0.10
   
     clouseau1:
       image: openjdk:8
       command: >
         java -server
         -classpath '/app/*'
         -Xmx2G -Dsun.net.inetaddr.ttl=30
         -Dsun.net.inetaddr.negative.ttl=30
         -Dlog4j.configuration=file:/config/log4j.properties
         -XX:OnOutOfMemoryError="kill -9 %p"
         -XX:+UseConcMarkSweepGC
         -XX:+CMSParallelRemarkEnabled com.cloudant.clouseau.Main /config/clouseau.ini
       restart: always
       depends_on:
       - couchdb1
       volumes:
       - ./config/clouseau:/config
       - ./data/clouseau/1:/data
       - ./clouseau-2.17.0:/app
       network_mode: service:couchdb1
   
   networks:
     couchdb-net:
       name: couchdb-net
       driver: bridge
       ipam:
         config:
           - subnet: 10.0.0.0/24
   ```
   
   ```shell
   docker-compose up
   ```
   
   Check it http://127.0.0.1:5984
   
   The "trick" is the `network_mode: service:couchdb1` in the the service `clouseau1`. With this we are telling clouseau1 service to use the same network of `couchdb1` service. So the ports (4369/epmd) are mapped to the clouseau1 container. For simplicity I just deploy one node, but we more easily, join them and deploy a loadbalancer with nginx/haproxy.
