usage

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

# you can also specify the image and image
# version to use for the service
# it *must* be compatible with the
# dokku/docker-grafana-graphite image
export GRAPHITE_IMAGE="dokku/docker-grafana-graphite"
export GRAPHITE_IMAGE_VERSION="latest"
dokku graphite:create lolipop

# you can also specify custom environment
# variables to start the graphite service
# in semi-colon separated form
export GRAPHITE_CUSTOM_ENV="USER=alpha;HOST=beta"
dokku graphite:create lolipop

# get connection information as follows
dokku graphite:info lolipop

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

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

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

# a graphite 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 graphite: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)
#
#   DOKKU_GRAPHITE_LOLIPOP_NAME=/random_name/GRAPHITE
#   DOKKU_GRAPHITE_LOLIPOP_PORT=tcp://172.17.0.1:8125
#   DOKKU_GRAPHITE_LOLIPOP_PORT_8125_UDP=udp://172.17.0.1:8125
#   DOKKU_GRAPHITE_LOLIPOP_PORT_8125_UDP_PROTO=tcp
#   DOKKU_GRAPHITE_LOLIPOP_PORT_8125_UDP_PORT=8125
#   DOKKU_GRAPHITE_LOLIPOP_PORT_8125_UDP_ADDR=172.17.0.1
#
# and the following will be set on the linked application by default
#
#   STATSD_URL=statsd://dokku-graphite-lolipop:8125
#
# 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 graphite:link other_service playground

# since STATSD_URL is already in use, another environment variable will be
# generated automatically
#
#   DOKKU_STATSD_BLUE_URL=statsd://dokku-graphite-other_service:8125

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

# this will replace STATSD_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:
#
#   STATSD_URL=statsd://dokku-graphite-other_service:8125
#   DOKKU_STATSD_BLUE_URL=statsd://dokku-graphite-other_service:8125
#   DOKKU_STATSD_SILVER_URL=statsd://dokku-graphite-lolipop:8125

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

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

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

Changing database adapter

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

dokku config:set playground STATSD_DATABASE_SCHEME=statsd2
dokku graphite:link lolipop playground

Will cause STATSD_URL to be set as statsd2://dokku-graphite-lolipop:8125

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

• Changing STATSD_URL manually to the new value.

OR

• Set STATSD_DATABASE_SCHEME back to its original setting
• Unlink the service
• Change STATSD_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 GRAPHITE_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.
