Deploy flink in docker swarm mode

Preconditions

  • You need docker-swarm running on your nodes
  • If you don’t have an appropriate network on your swarm create it with
    docker network create -d overlay --attachable --scope=swarm flink (if your network is named differently you have to adjust deploy.sh)
  • You are on your master node

Running

Build the images with
cd worker && docker build -t docker-swarm-flink-worker .
and
cd master && docker build -t docker-swarm-flink-master .

Adjust deploy.sh by setting MASTER_NODE to the address of your master node

Deploy using deploy.sh up

Remove using deploy.sh down

Notes

  • Flink has problems with dockers routing mesh, therefore you have to use --endpoint-mode dnsrr in the script and because you cannot to this with stack deploy this deploy script is necessary in the first place.
  • There are a lot environment variables you can set, but I would recommend to set the garbage collection to G1GC using deploy.sh --javaopts "-XX:+UseG1GC" up, because I’ve encountered some problems using java’s default garbage collection.
