Netflix conductor server local docker container is unhealthy

I am following the steps here to install & run Netflix Conductor locally on my desktop. I am trying to use docker-compose to bring all the services up. After initial problems of incorrect docker version, docker compose version, docker compose build problem (solved using this), I have hit a roadblock with this error -

/conductor/docker$ sudo docker-compose up

docker_elasticsearch_1 is up-to-date

docker_dynomite_1 is up-to-date

ERROR: for conductor-server Container "a89b4c61d465" is unhealthy.

ERROR: Encountered errors while bringing up the project.

Also i changed elasticsearch port to 10300 in docker-compose.yaml, server/config/config.properties & server/config/config-local.properties.

Docker compose version is 1.23.2. Docker version is 18.09.3.

PS: I am extremely new to dockers & related concepts.

More info: reverted my port change to default (9200/9300) & added docker information of unhealthy container (docker container-id changed due to re-build)

/conductor/docker$ sudo docker ps -a --filter "id=7be9f9b5288c" [sudo] password for anshuman: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

7be9f9b5288c docker.elastic.co/elasticsearch/elasticsearch:5.6.8 "/bin/bash bin/es-do…" 36 minutes ago Up 36 minutes (unhealthy) 0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp docker_elasticsearch_1

curl to elasticsearch seems ok.

/conductor/docker$ curl http://127.0.0.1:9200/_cat/health 1553188720 17:18:40 docker-cluster yellow 1 1 5 5 0 0 5 0 - 50.0%

Docker logs for the container give me this (no clue what they mean)

Who is a89b4c61d465? docker ps -a --filter "id= a89b4c61d465" should tell us that. – β.εηοιτ.βε
Added that information in the question. Looks like docker_elasticsearch_1 container is unhealthy. And looks like something to do with port configuration. – asr9

Finally, I figured out the problems to make this work. It required to at least get to know the basics of how docker and Dockerfile work.

  1. Based on the documentation here, I started the local server & was attempting to bring everything up using docker-compose. This gave me a port conflict.
  2. I resorted to incorrectly change port for elasticsearch. Realized this after I learnt basics of Dockerfile. This was the reason for my unhealthy container.

  3. Then there were errors in building conductor-ui.

    npm ERR! code EINTEGRITY

    This required a change in Dockerfile for conductor-ui. The npm install command was changed to npm install --no-shrinkwrap --update-binary (based on answer here). Other answers for this issue
