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

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>`

AFAIK `docker run` starts a new container to run the command. This should
probably be something like:
```
docker exec -it $(docker ps --filter name=flink_jobmanager
--format={{.ID}}) flink run -m <jobmanager:port> -c <your_class> <your_jar>
<your_params>
```
This would run the command on the existing JobManager container where the
jar was previously uploaded.
