# 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 form
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

Disabling docker pull calls

If you wish to disable the docker pull calls that the plugin triggers, you may set the ELASTICSEARCH_DISABLE_PULL environment variable to true. Once disabled, you will need to pull the service image you wish to deploy as shown in the stderr output.

Please ensure the proper images are in place when docker pull is disabled.
