+## Hadoop Docker
+
+### Running from existing setups
+
+There are special branches for running hadoop in docker.
+
+The `docker-hadoop-runner*` branches contain scripts that set up base images
that can be used for running any Hadoop version.
+
+*
[docker-hadoop-runner-latest](https://github.com/apache/hadoop/tree/docker-hadoop-runner-latest)
+*
[docker-hadoop-runner-jdk11](https://github.com/apache/hadoop/tree/docker-hadoop-runner-jdk11)
+*
[docker-hadoop-runner-jdk8](https://github.com/apache/hadoop/tree/docker-hadoop-runner-jdk8)
+*
[docker-hadoop-runner](https://github.com/apache/hadoop/tree/docker-hadoop-runner)
+
+The `docker-hadoop*` branches can be used for running a specific version.
+
+* [docker-hadoop-3](https://github.com/apache/hadoop/tree/docker-hadoop-3)
+ * `hadoop-3.3.6`
+* [docker-hadoop-2](https://github.com/apache/hadoop/tree/docker-hadoop-2)
+ * `hadoop-2.10.2`
+
+### Running from the source code
+
+There is a setup under `hadoop-dist` that contains Docker Compose definitions
+for running the current version of Hadoop in a multi-node docker environment.
+
+This is meant for testing code changes locally and debugging.
+
+The base image used by the Docker setup is built as part of the maven
lifecycle.
+The distribution files generated while building the project with the `-Pdist`
profile enabled,
+will be used for running hadoop inside the containers.
+
+In order to start the docker environment you need to do the following
+* Build the project, using the `-Pdist` profile
+ ```shell
+ > mvn clean install -Dmaven.javadoc.skip=true -DskipTests -DskipShade
-Pdist,src
+ ```
+* From the project root, navigate under the docker-compose dir under the
generated dist directory
+ ```shell
+ > cd hadoop-dist/target/hadoop-<current-version>/compose/hadoop
+ ```
+* Start the docker environment
+ ```shell
+ > docker-compose up -d --scale datanode=3
+ ```
+* Connect to a container to execute commands
+ ```shell
+ > docker exec -it hadoop_datanode_1 bash
+ bash-4.2$ hdfs dfs -mkdir /test
+ ```
+
+### Config files
+
+To add or remove properties from the `core-site.xml`, `hdfs-site.xml`, etc.
files used in the docker environment,
+simply edit the `config` file before starting the containers. The changes will
be persisted in the docker environment.
