+# Apache Accumulo Docker Image
+
+## Obtain the Docker image
+
+To obtain the docker image created by this project, you can either pull it from DockerHub at
+`apache/accumulo` or build it yourself. To pull the image from DockerHub, run the command below:
+
+ docker pull apache/accumulo
+
+While it is easier to pull from DockerHub, the image will default to the software versions below:
+
+| Software | Version |
+|-------------|---------------|
+| [Accumulo] | 1.9.3 |
+| [Hadoop] | 2.8.5 |
+| [Zookeeper] | 3.4.13 |
+
+If these versions do not match what is running on your cluster, you should consider building
+your own image with matching versions. However, Accumulo must be 2.0.0+. Below are instructions for
+building an image:
+
+1. Clone the Accumulo docker repo
+
+ git clone git@github.com:apache/accumulo-docker.git
+
+2. Build the default Accumulo docker image using the command below.
+
+ cd /path/to/accumulo-docker
+ docker build -t accumulo .
+
+ Or build the Accumulo docker image with specific released versions of Hadoop, Zookeeper, etc that will downloaded from Apache using the command below:
+
+ docker build --build-arg ZOOKEEPER_VERSION=3.4.8 --build-arg HADOOP_VERSION=2.7.0 -t accumulo .
+
+ Or build with an Accumulo tarball (located in same directory as DockerFile) using the command below:
+
+ docker build --build-arg ACCUMULO_VERSION=1.9.3-SNAPSHOT --build-arg ACCUMULO_FILE=accumulo-1.9.3-SNAPSHOT-bin.tar.gz -t accumulo .
+
+## Image basics
+
+The entrypoint for the Accumulo docker image is the `accumulo` script. While the primary use
+case for this image is to start Accumulo processes (i.e tserver, master, etc), you can run other
+commands in the `accumulo` script to test out the image:
+
+```bash
+# No arguments prints Accumulo command usage
+docker run accumulo
+# Print Accumulo version
+docker run accumulo version
+# Print Accumulo classpath
+docker run accumulo classpath
+```
