Using the Pre-Built Installer Container Images

This section describes how to obtain and run the pre-built Installer container images.

Pre-built Installer container images are available on Docker hub. Images are available for:

Ubuntu 16.04
Ubuntu 14.04
CentOS 7
CentOS 6

The pre-built images are about 200 MB. A sample-run script that you can use to start the container is available on GitHub.

To use a pre-built image:

Download the pre-built Installer container image and the sample-run script to a Linux or Mac OS X platform where Docker 1.12.5 or later is installed and the Docker daemon is up and running.
- You can download the pre-built image from the data-fabric public repository.
- You can download the sample-run script (mapr-docker-installer.sh) from this GitHub location.
(Optional) Edit the mapr-docker-installer.sh script file if you want to change any environmental variables. For more information about the environmental variables, see Environmental Variables for the Installer Container.
Run the mapr-docker-installer.sh file to start mapr-installer services:
```
$ ./docker_images/installer/mapr-docker-installer.sh
```
After the installer service is started, you can issue Stanza commands or open the web-based Installer in a browser:
```
installer (380) started with log /opt/mapr/installer/logs/installer.log
Started service mapr-installer

...Success

    To continue installing MapR software, open the following URL in a web browser

              If the address '172.17.0.2' is internal and not accessible
           from your browser, use the external address mapped to it instead

                              https://172.17.0.2:9443
 
```
The Installer maintains the state of the cluster. When the installer is run from a container, the installer database is only as persistent as the container itself. If you need the installer data to be persistent, here are some options:
- If you shut down a Installer container, use the docker start command (not the docker run command) to restart the same instance of the container. If you create a new instance of the container, the database will have no information.
- Mount the /opt/mapr/ data directory outside the container to persistent storage to maintain the cluster state.
- Use the Stanza export command to export the state of the cluster before you shut down the container. See Exporting a Cluster Configuration.
