Setting up ElasticSearch as the logging database

As in quite a few cases before, we'll start by creating the already familiar nodes (swarm-1, swarm-2, and swarm-3):

cd cloud-provisioning

git pull

scripts/dm-swarm.sh

All the commands from this chapter are available in the 08-logging.sh (https://gist.github.com/vfarcic/c89b73ebd32dbf8f849531a842739c4d) Gist.

The first service we'll create is Elastic Search (https://hub.docker.com/_/elasticsearch). Since we'll need it to be accessible from a few other services, we'll also create a network called elk:

eval $(docker-machine env swarm-1)

docker network create --driver overlay elk

docker service create \
    --name elasticsearch \
    --network elk \
    --reserve-memory 500m \
    elasticsearch:2.4

After a few moments, the elasticsearch service will be up and running.

We can check the status using the service ps command:

docker service ps elasticsearch...
