OpenShift usage of "headless" VNC Docker images

The following content uses as example the image consol/rocky-xfce-vnc of the Dockerfile Dockerfile.rocky-xfce-vnc.

Run the image from Dockerhub

cd openshift
oc new-project my-project

As soon as you are logged in and selected your oc project, you can simple run the image by using the configuration openshift.headless-vnc.run.yaml:

oc process -f openshift.headless-vnc.run.yaml -v APPLICATION_NAME=myrunonlypod IMAGE=consol/rocky-xfce-vnc | oc create -f -
# service "my-run-only-pod" created
# route "my-run-only-pod" created
# imagestream "my-run-only-pod" created
# deploymentconfig "my-run-only-pod" created

After the deployment you will see at your management UI the new deployed service ``:

https://YOUR-OS-MANAGEMENT-URL/console/project/my-project/overview

openshift management consol run-only service

Over the URL you can look and control the fresh deployed container via the web-vnc interface:

http://my-run-only-pod-my-project.YOUR-OS-URL/?password=vncpassword

openshift container via webvnc

Build & Run your own image

If you want to build the image in your own infrastructure just use the configuration openshift.headless-vnc.buildandrun.yaml:

oc process -f openshift.headless-vnc.buildandrun.yaml -v APPLICATION_NAME=my-rocky-xfce-image,SOURCE_DOCKERFILE=Dockerfile.rocky-xfce-vnc,SOURCE_REPOSITORY_REF=master | oc create -f -
# service "my-rocky-xfce-image" created
# route "my-rocky-xfce-image" created
# imagestream "my-rocky-xfce-image" created
# buildconfig "my-rocky-xfce-image" created
# deploymentconfig "my-rocky-xfce-image" created

Now a fresh image build will be triggerd, see:

https://YOUR-OS-MANAGEMENT-URL/console/project/my-project/browse/builds/my-rocky-xfce-image/my-rocky-xfce-image-1?tab=logs

openshift headless vnc docker image build

After the image is successfully built, openshift will autmaticly will deploy it as new service:

https://YOUR-OS-MANAGEMENT-URL/console/project/my-project/overview

openshift management consol build own image service

After the deployment, you you can look and control the fresh deployed container via the web-vnc interface:

http://my-rocky-xfce-image.YOUR-OS-URL/?password=vncpassword
