Chapter 9. Run OptaWeb Vehicle Routing on Red Hat OpenShift Container Platform

Linux users can use the runOnOpenShift.sh Bash script to install OptaWeb Vehicle Routing on Red Hat OpenShift Container Platform.

Note

The runOnOpenShift.sh script does not run on macOS.

Prerequisites

You have access to an OpenShift cluster and the OpenShift command-line interface (oc) has been installed. For information about Red Hat OpenShift Container Platform, see Installing OpenShift Container Platform.
OptaWeb Vehicle Routing has been successfully built with Maven as described in Chapter 6, Download and build the OptaWeb Vehicle Routing deployment files.
Internet access is available.

Procedure

Enter the following command where <PROJECT_NAME> is the name of your new project:
```
oc new-project <PROJECT_NAME>
```
If necessary, change directory to optaweb-vehicle-routing-distribution-7.48.0.Final-redhat-00004/sources.
Enter the following command to execute the runOnOpenShift.sh script and download an OpenStreetMap (OSM) file:
```
./runOnOpenShift.sh <OSM_FILE_NAME> <COUNTRY_CODE_LIST> <OSM_FILE_DOWNLOAD_URL>
```
In this command, replace the following variables:
- <OSM_FILE_NAME>: The name of a file downloaded from <OSM_FILE_DOWNLOAD_URL>.
- <COUNTRY_CODE_LIST>: A comma-separated list of country codes used to filter geosearch queries. For a list of country codes, see ISO 3166 Country Codes.
- <OSM_FILE_DOWNLOAD_URL>: The URL of an OSM data file in PBF format accessible from OpenShift. The file will be downloaded during backend startup and saved as /deployments/local/<OSM_FILE_NAME>.
  The following example configures OptaWeb Vehicle Routing to filter geosearch results to Belgium and downloads the latest Belgium OSM extract from Geofabrik:
  In the following example, OptaWeb Vehicle Routing downloads the OSM map of Central America (central-america-latest.osm.pbf) and searches in the countries Belize (BZ) and Guatemala (GT).
  ./runOnOpenShift.sh central-america-latest.osm.pbf BZ,GT http://download.geofabrik.de/europe/central-america-latest.osm.pbf

Note

For help with the runOnOpenShift.sh script, enter ./runOnOpenShift.sh --help.
