- Step 2 - Reviewing the Job Output
- Step 3 - Confirming in the RHSI Web Interface
Objective
In this exercise, we’ll validate that the configuration we’ve done so far is correct, and that our edge devices are now accessible from within our namespace in OpenShift.
Should everything work as expected, the edge devices will now be managable using Ansible, providing a consistent experience, even though we can’t directly SSH to the systems.
Step 1 - Running the Test Device Connectivity Job Template
In the Ansible Controller webUI, navigate to Resources > Templates. A job template has been pre-provisioned for you named Test Device Connectivity.
This job template is pointed at the Edge Devices inventory, where we added our edge host, and has a set of machine credentials that will allow authentication to the device. In addition, it’s set to use the hello-world.yml playbook in our code repository, which simply runs the setup module against the target systems.
There’s no need to modify this job template, simply hit the Launch button.
Step 2 - Reviewing the Job Output
Normally, Controller will automatically direct you to the output page of a job after hitting Launch on a job template. If it does not, navigate to Views > Jobs in the web interface, and select the job named Test Device Connectivity.
Here, the job should have been successful, with an output similar to:
Clicking on the line under the Run the setup module task header will expose more information about the specific task. On the JSON tab, the ansible facts should be displayed in json format:
If the job template ran successfully, then the host can be contacted by Ansible Controller and is ready for management.
Step 3 - Confirming in the RHSI Web Interface
As an extra layer of confirmation, we can revisit the RHSI web interface and look at the details of the ssh service we created earlier. After the job has run and complete, we should have some traffic statistics:
