Demonstation of qgis (https://www.qgis.org) on ppc64le. Here, we have supplied a Dockerfile to build container image that runs QGIS Server on ppc64le

Attribution: This is just demonstation of how one can use QGIS inside docker container for an architecture like ppc64le, and not original work. Please refer to https://www.qgis.org ,for complete introduction and details about the free opensource professional and powerful desktop GIS.

QGIS documentation: https://www.qgis.org/en/docs/index.html

Steps to build a sample docker image on ppc64le

Step 1: Clone the repositoy, Navigate to ppc64le-qgis

$ git clone https://github.com/mithunhr87/ppc64le-qgis.git
$ cd ppc64le-qgis

Step 2: Build the docker image , Please substitute the image name and version you prefer in below command

$ export IMAGE=ppc64le
$ export TAG=qgis
$ docker build -t  $IMAGE:$TAG .

Step 3: Run the docker image with port mapping , first entry will be hostport, second port entry is container port, Here we have used 6080 at both the places The docker image uses noVNC - https://github.com/novnc/noVNC to provision VNC to browser

$ docker run -it -p 6080:6080 $IMAGE:$TAG

Step4: once the container is running, Navigate to http://<hostname>:6080/vnc.html, TestVNC is the password, can be changed in entrypoint.sh script as needed. qgis running inside a container will appear on successfull connection to vnc

A sample .shp file of Alaska will appear on the qgis, However you can open and use any gis supported file/project

Deployment on OpenShift

To deploy newly built qgis container image for ppc64le architecture, navigate to ppc64le-qgis repository

1. Logon to OpenShift

$ oc login -u <username> -p <password>

2. Create a new project in the OCP -

$ export PROJECT=ppc64le-isv
$ oc new-project $PROJECT

3. Update the security constraint, as shown below -

$ oc adm policy add-scc-to-user privileged -z default -n <project name>

$ oc adm policy add-scc-to-user anyuid -z default -n <project name>

4. Create the deployment, Update Namespace as project name which you have used in step 2, other fields could be modified if required but not mandatory

$ oc create -f deployment.yaml

5. create the service, Update Namespace as project name, again ther fields could be modified if required but not mandatory

$ oc create -f service.yaml

6. Expose the qgis service here our qgis service name is qgis-service

$ oc expose service qgis-service

7. Query the route

$ oc get route

8. The route name will have host/port filed which is the link to access the noVNC client For example

$ oc get route
NAME           HOST/PORT                                         PATH   SERVICES       PORT   TERMINATION   WILDCARD
qgis-service   qgis-service-mithunhr.apps.p1258.cecc.ihost.com          qgis-service   6080                 None

qgis-service-mithunhr.apps.p1258.cecc.ihost.com Is your route to access the application.

9. Navigate via web browser, click the route as shown in Step 8

10. Click to connect

11. Enter password for VNC - here it is TestVNC

12. you would see a sample map of Alaska loaded , You can open and work on any supported QGIS project or file
