+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+
+kafka-docker
+============
+
+Dockerfile for [Apache Kafka](http://kafka.apache.org/)
+
+The image is available directly from https://registry.hub.docker.com/
+
+##Pre-Requisites
+
+- install docker-compose [https://docs.docker.com/compose/install/](https://docs.docker.com/compose/install/)
+- modify the ```KAFKA_ADVERTISED_HOST_NAME``` in ```docker-compose.yml``` to match your docker host IP (Note: Do not use localhost or 127.0.0.1 as the host ip if you want to run multiple brokers.)
+- if you want to customise any Kafka parameters, simply add them as environment variables in ```docker-compose.yml```, e.g. in order to increase the ```message.max.bytes``` parameter set the environment to ```KAFKA_MESSAGE_MAX_BYTES: 2000000```. To turn off automatic topic creation set ```KAFKA_AUTO_CREATE_TOPICS_ENABLE: 'false'```
+
+##Usage
+
+Start a cluster:
+
+- ```docker-compose up -d ```
+
+Add more brokers:
+
+- ```docker-compose scale kafka=3```
+
+Destroy a cluster:
+
+- ```docker-compose stop```
+
+##Note
+
+The default ```docker-compose.yml``` should be seen as a starting point. By default each broker will get a new port number and broker id on restart. Depending on your use case this might not be desirable. If you need to use specific ports and broker ids, modify the docker-compose configuration accordingly, e.g. [docker-compose-single-broker.yml](https://github.com/wurstmeister/kafka-docker/blob/master/docker-compose-single-broker.yml):
+
+- ```docker-compose -f docker-compose-single-broker.yml up```
+
+##Broker IDs
+
+If you don't specify a broker id in your docker-compose file, it will automatically be generated (see [https://issues.apache.org/jira/browse/KAFKA-1070](https://issues.apache.org/jira/browse/KAFKA-1070). This allows scaling up and down. In this case it is recommended to use the ```--no-recreate``` option of docker-compose to ensure that containers are not re-created and thus keep their names and ids.
+
+
+##Automatically create topics
+
+If you want to have kafka-docker automatically create topics in Kafka during
+creation, a ```KAFKA_CREATE_TOPICS``` environment variable can be
+added in ```docker-compose.yml```.
+
+Here is an example snippet from ```docker-compose.yml```:
+
+        environment:
+          KAFKA_CREATE_TOPICS: "Topic1:1:3,Topic2:1:1"
+
+```Topic 1``` will have 1 partition and 3 replicas, ```Topic 2``` will have 1 partition and 1 replica.
+
+##Advertised hostname 
+
+You can configure the advertised hostname in different ways 
+
+1. explicitly, using ```KAFKA_ADVERTISED_HOST_NAME``` 
+2. via a command, using ```HOSTNAME_COMMAND```, e.g. ```HOSTNAME_COMMAND: "route -n | awk '/UG[ \t]/{print $$2}'"```
+
+When using commands, make sure you review the "Variable Substitution" section in [https://docs.docker.com/compose/compose-file/](https://docs.docker.com/compose/compose-file/)
+
+If ```KAFKA_ADVERTISED_HOST_NAME``` is specified, it takes presendence over ```HOSTNAME_COMMAND```
+
+For AWS deployment, you can use the Metadata service to get the container host's IP:
+```
+HOSTNAME_COMMAND=wget -t3 -T2 -qO-  http://169.254.169.254/latest/meta-data/local-ipv4
+```
+Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html
