Kafka on Docker on Photon with AppCatalyst

Kafka on Docker on Photon with AppCatalyst

so, something to note with AppCatalyst; the Photon VMs are very small (memory-wise).  as such, spooling up some containers, like spotify/kafka, won't start.  so here's a simple one;

sudo docker run -d --name other_kafka -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=localhost --env ADVERTISED_PORT=9092 --env KAFKA_HEAP_OPTS="-Xmx256M -Xms128M" spotify/kafka

the memory settings help get it off the ground on appcatalyst-photon.

(which kind of goes against the 12 factor grain of "close-to-production" as possible given the docker script is altered to fit the VM...)

VMware Photon and Docker Remote Service

How to Enable Docker Remote Access on VMware Photon

1. "sudo -s"
2. "nano /etc/systemd/system/multi-user.target.wants/docker.service"
3. change ExecStart to "ExecStart=/bin/docker -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock -d -s overlay"
4. save, exit, and restart the VM
5. test with "curl localhost:2375/info" and the response should be a JSON document
