# create a elasticsearch service named lolipop
dokku elasticsearch:create lolipop

# you can also specify the image and image
# version to use for the service
# it *must* be compatible with the
# official elasticsearch image
export ELASTICSEARCH_IMAGE="elasticsearch"
dokku elasticsearch:create lolipop

# you can also specify custom environment
# variables to start the elasticsearch service
# in semi-colon separated forma
dokku elasticsearch:create lolipop

# get connection information as follows
dokku elasticsearch:info lolipop

# you can also retrieve a specific piece of service info via flags
dokku elasticsearch:info lolipop --config-dir
dokku elasticsearch:info lolipop --data-dir
dokku elasticsearch:info lolipop --dsn
dokku elasticsearch:info lolipop --exposed-ports
dokku elasticsearch:info lolipop --id
dokku elasticsearch:info lolipop --internal-ip
dokku elasticsearch:info lolipop --links
dokku elasticsearch:info lolipop --service-root
dokku elasticsearch:info lolipop --status
dokku elasticsearch:info lolipop --version

# a bash prompt can be opened against a running service
# filesystem changes will not be saved to disk
dokku elasticsearch:enter lolipop

# you may also run a command directly against the service
# filesystem changes will not be saved to disk
dokku elasticsearch:enter lolipop ls -lah /

# a elasticsearch service can be linked to a
# container this will use native docker
# links via the docker-options plugin
# here we link it to our 'playground' app
# NOTE: this will restart your app
dokku elasticsearch:link lolipop playground

# the following environment variables will be set automatically by docker (not
# on the app itself, so they won’t be listed when calling dokku config)
# and the following will be set on the linked application by default
#   ELASTICSEARCH_URL=http://dokku-elasticsearch-lolipop:9200
# NOTE: the host exposed here only works internally in docker containers. If
# you want your container to be reachable from outside, you should use `expose`.

# another service can be linked to your app
dokku elasticsearch:link other_service playground

# since ELASTICSEARCH_URL is already in use, another environment variable will be
# generated automatically
#   DOKKU_ELASTICSEARCH_BLUE_URL=http://dokku-elasticsearch-other-service:9200

# you can then promote the new service to be the primary one
# NOTE: this will restart your app
dokku elasticsearch:promote other_service playground

# this will replace ELASTICSEARCH_URL with the url from other_service and generate
# another environment variable to hold the previous value if necessary.
# you could end up with the following for example:
#   ELASTICSEARCH_URL=http://dokku-elasticsearch-other-service:9200
#   DOKKU_ELASTICSEARCH_BLUE_URL=http://dokku-elasticsearch-other-service:9200
#   DOKKU_ELASTICSEARCH_SILVER_URL=http://dokku-elasticsearch-lolipop:9200

# you can also unlink an elasticsearch service
# NOTE: this will restart your app and unset related environment variables
dokku elasticsearch:unlink lolipop playground

# you can tail logs for a particular service
dokku elasticsearch:logs lolipop
dokku elasticsearch:logs lolipop -t # to tail

# finally, you can destroy the container
dokku elasticsearch:destroy lolipop

Changing database adapter

It's possible to change the protocol for ELASTICSEARCH_URL by setting the environment variable ELASTICSEARCH_DATABASE_SCHEME on the app:

dokku config:set playground ELASTICSEARCH_DATABASE_SCHEME=elasticsearch2
dokku elasticsearch:link lolipop playground

Will cause ELASTICSEARCH_URL to be set as elasticsearch2://dokku-elasticsearch-lolipop:9200

CAUTION: Changing ELASTICSEARCH_DATABASE_SCHEME after linking will cause dokku to believe the elasticsearch is not linked when attempting to use dokku elasticsearch:unlink or dokku elasticsearch:promote. You should be able to fix this by

  • Changing ELASTICSEARCH_URL manually to the new value.


  • Set ELASTICSEARCH_DATABASE_SCHEME back to its original setting
  • Unlink the service
  • Change ELASTICSEARCH_DATABASE_SCHEME to the desired setting
  • Relink the service
