can we create a docker image with multiple instances in it? - docker

Question

I want an image with elasticsearch and zipkin in it but i dont want to download it from docker hub instead I have downloaded the tar.gz file of those and then creating those images. I am able to run both of them individually but not simultaneously (by docker run command).
Please see below Dockerfile
FROM openjdk:11
RUN groupadd -g 1000 elk-zipkin && useradd elk-zipkin -u 1000 -g 1000
RUN mkdir /usr/share/elasticsearch/
RUN mkdir /usr/share/zipkin
#RUN mkdir /usr/share/kibana
COPY /artifacts/elasticsearch-7.17.6.tar.gz /usr/share/elasticsearch
COPY artifacts/zipkin.jar /usr/share/zipkin
#COPY /artifacts/kibana-7.17.6.tar.gz /usr/share/kibana
COPY script.sh /usr/share/zipkin
WORKDIR /usr/share/elasticsearch
RUN tar xvf elasticsearch-7.17.6.tar.gz
#RUN tar xvf kibana-7.17.6.tar.gz
WORKDIR /usr/share/elasticsearch/elasticsearch-7.17.6
RUN set -ex && for path in data logs config config/scripts; do \
mkdir -p "$path"; \
chown -R elk-zipkin:elk-zipkin "$path"; \
done
USER elk-zipkin
ENV PATH=$PATH:/usr/share/elasticsearch/elasticsearch-7.17.6/bin
WORKDIR /usr/share/elasticsearch/elasticsearch-7.17.6/config
#RUN sed -i "s|#network.host: 192.168.0.1|network.host: 0.0.0.0|g" elasticsearch.yml
#RUN sed -i "s|#discovery.seed_hosts: ["host1", "host2"]|discovery.type: single-node|g" elasticsearch.yml
COPY /artifacts/elasticsearch.yml /usr/share/elasticsearch/elasticsearch-7.17.6/config
#CMD ["elasticsearch"]
#EXPOSE 9200 9300
#WORKDIR /usr/share/zipkin
#CMD ["java","-jar","zipkin.jar"]
#EXPOSE 9411
WORKDIR /usr/share/zipkin
CMD ["sh","script.sh"]
script.sh:
java -jar zipkin.jar elasticsearch
Run command for them:
for zipkin -
docker run -d --name=zipkin \ -p=9411:9411 \ --env=STORAGE_TYPE="elasticsearch" \ --env=ES_HOSTS="someurl" IMAGEID
for elasticsearch -
docker run -d --name=elasticsearch1 -p=9200:9200 -p=9300:9300 IMAGEID
I have tried to run both of the service i.e. elasticsearch and zipkin individually and simultaneously.
I am expecting that both should be in one image and by only single docker run command both of the services should get run.

Answer 1

Somehow I made it, one can create a Dockerfile like mentioned in the question and then have to pass some sleep time into the script file to give some extra time for getting up the previous services.
Example:
nohup elasticsearch &
sleep 10
nohup java -jar zipkin.jar
Note: As per comments and the basics of container, one should not create multiple services inside the same container.
