Dear community,
I'm new to elastic & i'm trying to cloud-ize my application via docker then kubernetes.
I've built the same Springboot app as:
> **[How to use Java High Level Rest Client with Spring Boot to talk to AWS...](https://medium.com/@sourav.pati09/how-to-use-java-high-level-rest-client-with-spring-boot-to-talk-to-aws-elasticsearch-2b6106f2e2c)**

To test this app:
**1. Pull docker image**
a. docker pull [docker.elastic.co/elasticsearch/elasticsearch:6.8.2](http://docker.elastic.co/elasticsearch/elasticsearch:6.8.2)
b. docker pull [docker.elastic.co/elasticsearch/kibana:6.8.2](http://docker.elastic.co/elasticsearch/kibana:6.8.2)
**2. Run image on docker**
a. docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" [docker.elastic.co/elasticsearch/elasticsearch:6.8.2](http://docker.elastic.co/elasticsearch/elasticsearch:6.8.2)
b. docker run --link :elasticsearch -p 5601:5601 [docker.elastic.co/kibana/kibana:6.8.2](http://docker.elastic.co/kibana/kibana:6.8.2)
**3. both locahost:9200 & 5601 are ping-able**
**4. mvn package app into jar & run it**
java -jar elastic-client-0.0.1-LOCAL.jar
**4.5. application.properties**
elasticsearch.host=http://localhost:9200
**5. CRUD successful via curl or "postman" (a restful client) works too**
**6. build docker image successfully then push to private repo by:**
docker build -t hironwayj/elastic-client-local .
docker push hironwayj/elastic-client-local
here's my dockerfile:
FROM maven:3.5-jdk-8-alpine as builder
WORKDIR /app
COPY pom.xml .
COPY src ./src
RUN mvn package -DskipTests
FROM openjdk:8-jre-alpine
COPY --from=builder /app/target/elastic-client-0.0.1-LOCAL.jar /elastic-client-local.jar
CMD ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/elastic-client-local.jar"]
**7. run docker image**
docker run -p 8080:8080 hironwayj/elastic-client-local
**8. Failed when CRUD with connection refused**
java.net.ConnectException: Connection refused

**Did i configure somewhere wrong? Why is java -jar runnable while failed in docker image?**
Thank you so much!
