Elasticsearch container exists with no logs

Elastic Stack Elasticsearch
1

Hello Experts

I'm working on setting up ELK stack on docker swarm. I'm trying to configure the official elastic search image with the ssl certs. The containers are failing with no logs. Can someone suggest what is wrong here?

Dockerfile:

FROM docker.elastic.co/elasticsearch/elasticsearch:6.4.2

# General environment values
ENV VAULT_VERSION=0.9.0 \
    CERTS_DIR=/usr/share/elasticsearch/config/x-pack/certificates     


# Install vault

RUN curl -L "https://releases.hashicorp.com/vault/${VAULT_VERSION}/vault_${VAULT_VERSION}_linux_amd64.zip" -o /tmp/vault.zip && \
    unzip /tmp/vault.zip -d /usr/local/bin && \
    rm -f /tmp/vault.zip

# Create directory for ssl certs

Is there really no output at all? Even from Compose?

Did your docker-compose.yml get pasted correctly in the forum? Some of the indentation looks wrong:

volumes:
  esmaster1:
driver: local
  esdata1:
driver: local
