Requirements

a docker swarm with n managers, p workers

1/ Prepare configuration files

on managers :
create /etc/kapacitor/config/kapacitor.conf from
https://github.com/influxdata/sandbox/blob/master/kapacitor/config/kapacitor.conf
create /etc/influxdb/config/influxdb.conf from
https://github.com/influxdata/sandbox/blob/master/influxdb/config/influxdb.conf
on managers & workers :
create /etc/telegraf/telegraf.conf from
https://github.com/influxdata/sandbox/blob/master/telegraf/telegraf.conf
In telegraf.conf replace $HOSTNAME with the name of the node (otherwise it will be <CONTAINER_ID>)

2/ Copy and Run the stack

on a manager :
copy the above docker-compose-tick.yml file
run command :

docker stack deploy --compose-file docker-compose-tick.yml tick

Advises
If you have more than one manager (and you should), as distributed filesystem is not yet available within docker, to avoid data loss upon restart, I advise you to :

In docker-compose-tick.yml set the constraint node to one manager by hostname :

constraints:
  - node.hostname == <ONE_MANAGER_NODE_HOSTNAME>

At the end of telegraf.conf, only keep inputs.influxdb configuration on the manager node where influxdb is constrained :

[[inputs.influxdb]]
  urls = ["http://influxdb:8086/debug/vars"]

3/ Set up

Go to Chronograf URL : http://<LAN_IP_OF_A_NODE>:8888
Homepage > Set Connection String to http://influxdb:8086

Menu ALERTING > Configure Kapacitor > set URL to http://kapacitor:9092
Caution

influxdb and kapacitor components are not clustered
