# How to build, publish and run a Apache Drill Docker image
## Prerequisites
To build an Apache Drill docker image, you need to have the following software installed on your system to successfully complete a build.
* [Java 8](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
* [Maven 3.3.3 or greater](https://maven.apache.org/download.cgi)
* [Docker CE](https://store.docker.com/search?type=edition&offering=community)
If you are using an older Mac or PC, additionally configure [docker-machine](https://docs.docker.com/machine/overview/#what-is-docker-machine) on your system
## Checkout
```
git clone https://github.com/apache/drill.git
```
## Build Drill
```
$ cd drill
$ mvn clean install
```
## Build Docker Image
```
$ cd distribution
$ mvn dockerfile:build -Pdocker
```
## Push Docker Image
By default, the docker image built above is configured to be pushed to [Drill Docker Hub](https://hub.docker.com/r/drill/apache-drill/) to create official Drill Docker images.
```
$ cd distribution
$ mvn dockerfile:push -Pdocker
```
You can configure the repository in pom.xml to point to any private or public container registry, or specify it in your mvn command.
```
$ cd distribution
$ mvn dockerfile:push -Pdocker -Pdocker.repository=<my_repo>
```
## Run Docker Container
Running the Docker container should start Drill in embedded mode and connect to Sqlline.
```
$ docker run -i --name drill-1.14.0 -p 8047:8047 -t drill/apache-drill:1.14.0 /bin/bash
Jun 29, 2018 3:28:21 AM org.glassfish.jersey.server.ApplicationHandler initialize
INFO: Initiating Jersey application, version Jersey: 2.8 2014-04-29 01:25:26...

"json ain't no thang"

+------------+
| version |
+------------+
| 1.14.0 |
+------------+
1 row selected (0.28 seconds)
```
You can also run the container in detached mode and connect to sqlline using drill-localhost.
```
$ docker run -i --name drill-1.14.0 -p 8047:8047 --detach -t drill/apache-drill:1.14.0 /bin/bash
<displays container ID>
$ docker exec -it drill-1.14.0 bash
<connects to container>
$ /opt/drill/bin/drill-localhost
apache drill 1.14.0
"json ain't no thang"
0: jdbc:drill:drillbit=localhost> select version from sys.version;
+------------+
| version |
+------------+
| 1.14.0 |
+------------+
1 row selected (0.28 seconds)
```
## Querying Data
By default, you can only query files which are accessible within the container. For example, the sample data which ships with Drill.
```
> select first_name, last_name from cp.`employee.json` limit 1;
+-------------+------------+
| first_name | last_name |
+-------------+------------+
| Sheri | Nowmer |
+-------------+------------+
1 row selected (0.256 seconds)
```
To query files outside of the container, you can configure [docker volumes](https://docs.docker.com/storage/volumes/#start-a-service-with-volumes)
## Drill Web UI
Drill web UI can be accessed using http://localhost:8047 once the Drill docker container is up and running. On Windows, you may need to specify the IP address of your system instead of 'localhost'.
