when running containers.
+ docker build -t flink .
-The base image installs Oracle Java JDK 1.7 and SSH client & server. You
can change the SSH password there or add your own key and adjust SSH config.
+If you want to build the container for a specific version of
flink/hadoop/scala
+you can configure it in the respective args:
-- Run `./build.sh`
+ docker build --build-arg FLINK_VERSION=1.0.3 --build-arg
HADOOP_VERSION=26 --build-arg SCALA_VERSION=2.10 -t
"flink:1.0.3-hadoop2.6-scala_2.10" flink
-###Deploy
+# Deploy
- Deploy cluster and see config/setup log output (best run in a screen
session)
-`docker-compose up`
+ docker-compose up
- Deploy as a daemon (and return)
-`docker-compose up -d`
+ docker-compose up -d
- Scale the cluster up or down to *N* TaskManagers
-`docker-compose scale taskmanager=<N>`
-
-- Access the JobManager node with SSH (exposed on Port 220)
+ docker-compose scale taskmanager=<N>
-`ssh root@localhost -p 220`
+- Access the Job Manager container
-or on Mac OS X with boot2docker
-
-`ssh root@$(boot2docker ip) -p 220`
-
-The password is 'secret'
+ docker exec -it $(docker ps --filter name=flink_jobmanager
--format={{.ID}}) /bin/sh
- Kill the cluster
-`docker-compose kill`
+ docker-compose kill
- Upload a jar to the cluster
-`scp -P 220 <your_jar> root@localhost:/<your_path>`
+ for i in $(docker ps --filter name=flink --format={{.ID}}); do
+ docker cp <your_jar> $i:/<your_path>
+ done
- Run a topology
-`ssh -p 220 root@localhost /usr/local/flink/bin/flink run -c <your_class>
<your_jar> <your_params>`
+ docker run -it --rm flink:latest flink run -m <jobmanager:port> -c

Yes, you are right, I hesitated about this, if you noticed, I added a third
option apart of jobmanager/taskmanager to let the image open ended, my goal was
in part that people could start an container with flink as a client, or for any
other use. However this can be confusing (because people mostly expect to send
ther local jar, but I will change it as you suggest in the README, and advanced
users can do as they wish.
