1) append this line to the Dockerfile,

   so that bitcoind is started auto when container image is run

ENTRYPOINT ./bin/bitcoind -datadir=node -daemon && /bin/bash

2) rebuild the image

 docker build -t bitcoin-docker .

3) tag image for upload to registry

docker tag <image> username/repository:tag

4) upload tagged image to registry

docker push username/repository:tag

6) init the swarm, swarm is a group of machines and joined as cluster

swarm manager uses several strategies to run containers.

docker swarm init

7) run the specified docker compose file

docker stack deploy -c <composefile> <appname>
