+## Flink with Docker Compose
-### Passing configuration via environment variables
+[Docker Compose](https://docs.docker.com/compose/) is a way to run a group of
Docker containers locally.
+The next sections show examples of configuration files to run Flink.
-When you run Flink image, you can also change its configuration options by
setting the environment variable `FLINK_PROPERTIES`:
+### General
-```sh
-$ FLINK_PROPERTIES="jobmanager.rpc.address: host
-taskmanager.numberOfTaskSlots: 3
-blob.server.port: 6124
-"
-$ docker run --env FLINK_PROPERTIES=${FLINK_PROPERTIES} flink:{{< stable
>}}{{< version >}}-scala{{< scala_version >}}{{< /stable >}}{{< unstable
>}}latest{{< /unstable >}} <jobmanager|standalone-job|taskmanager>
-```
+* Create the docker-compose.yaml file. Please check the examples in the
sections below:
+ * [Application Mode](#app-cluster-yml)
+ * [Session Mode](#session-cluster-yml)
+ * [Session Mode with SQL Client](#session-cluster-sql-yaml)
-The [`jobmanager.rpc.address`]({{< ref "docs/deployment/config"
>}}#jobmanager-rpc-address) option must be configured, others are optional to
set.
+* Launch a cluster in the foreground (use `-d` for background)
-The environment variable `FLINK_PROPERTIES` should contain a list of Flink
cluster configuration options separated by new line,
-the same way as in the `flink-conf.yaml`. `FLINK_PROPERTIES` takes precedence
over configurations in `flink-conf.yaml`.
+ ```sh
+ $ docker-compose up
+ ```
-### Provide custom configuration
+* Scale the cluster up or down to `N` TaskManagers
-The configuration files (`flink-conf.yaml`, logging, hosts etc) are located in
the `/opt/flink/conf` directory in the Flink image.
-To provide a custom location for the Flink configuration files, you can
+ ```sh
+ $ docker-compose scale taskmanager=<N>
+ ```
-* **either mount a volume** with the custom configuration files to this path
`/opt/flink/conf` when you run the Flink image:
+* Access the JobManager container
```sh
- $ docker run \
- --mount type=bind,src=/host/path/to/custom/conf,target=/opt/flink/conf
\
- flink:{{< stable >}}{{< version >}}-scala{{< scala_version >}}{{<
/stable >}}{{< unstable >}}latest{{< /unstable >}}
<jobmanager|standalone-job|taskmanager>
+ $ docker exec -it $(docker ps --filter name=jobmanager --format={{.ID}})
/bin/sh
```
-* or add them to your **custom Flink image**, build and run it:
-
+* Kill the cluster
