Build a multi node Kafka cluster on docker swarm -


i found docker image kafka

https://hub.docker.com/r/spotify/kafka/

and can create docker container using command documented in link

docker run -p 2181:2181 -p 9092:9092 --env advertised_host=`boot2docker ip` --env advertised_port=9092 spotify/kafka

this good. want configure "multiple" node kafka cluster running on docker swarm.

how can that?

i have been trying docker 1.12 using docker swarm mode

create nodes

docker-machine create -d virtualbox  master docker-machine create -d virtualbox  slave master_config=$(docker-machine config master | tr -d '\"') slave_config=$(docker-machine config slave | tr -d '\"') master_ip=$(docker-machine ip master) docker $master_config swarm init --advertise-addr $master_ip --listen-addr $master_ip:2377 worker_token=$(docker $master_config swarm join-token worker -q) docker $slave_config swarm join --token $worker_token  $master_ip:2377 eval $(docker-machine env master)

create zookeeper service

docker service create --name zookeeper \     --constraint 'node.role == manager' \     -p 2181:2181 \     wurstmeister/zookeeper

create kafka service

docker service create --name kafka \     --mode global \     -e 'kafka_port=9092' \     -e 'kafka_advertised_port=9092' \     -e 'kafka_listeners=plaintext://0.0.0.0:9092' \     -e 'kafka_zookeeper_connect=tasks.zookeeper:2181' \     -e "hostname_command=ip r | awk '{ ip[\$3] = \$nf } end { print ( ip[\"eth0\"] ) }'" \     --publish '9092:9092' \     wurstmeister/kafka

though reason work within ingress or user defined overlay network , connection break kafka if try , connect through 1 of guest machines.

changing advertised ip doesn't make things better...

docker service create --name kafka \     --mode global \     -e 'kafka_port=9092' \     -e 'kafka_advertised_port=9092' \     -e 'kafka_listeners=plaintext://0.0.0.0:9092' \     -e 'kafka_zookeeper_connect=tasks.zookeeper:2181' \     -e "hostname_command=curl 192.168.99.1:5000" \     --publish '9092:9092' \     wurstmeister/kafka

i think new mesh networking , load balancing in docker might interfering kafka connection how....

to host container have flask app running locally curl

from flask import flask flask import request  app = flask(__name__)  @app.route('/') def hello_world():     return request.remote_addr

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
