Updated for OCP 4.1 DO288 Red Hat OpenShift Development I

[zachgutterman]

Hey learners! Last week we released a big updated for DO288 for OpenShift 4. Please take a look below at our release announcement and check out the new course in RHLS. Looking forward to your feedback!

Containers and OpenShift have quickly become the defacto solution for agile development and application deployment. Administrators and developers are seeking ways to improve application time-to-market for minimum viable products.  This course provides the gateway to organizational and digital transformation by providing an understanding of the potential of DevOps using a container-based architecture. 

A container-based architecture, orchestrated with Kubernetes and OpenShift, improves application reliability and, scalability, while decreasing developer overhead as well as facilitating continuous deployment.  Building on the container foundations set in DO180, DO288 is the first developer-focused OpenShift course.

Red Hat OpenShift Development I (DO288) teaches students how to design, build, and deploy containerized software applications to an OpenShift cluster. This course provides the gateway to organizational and digital transformation by providing an understanding of the potential of DevOps using a container-based architecture and enabling developers to leverage container technology to deploy their applications.

Whether writing container-native applications or migrating existing brownfield applications, this course provides hands-on training to boost developer productivity powered by Red Hat OpenShift for developers, administrators, and site reliability engineers. The final outcome from adopting a container-based architecture should lead toward more efficient development and increased overall productivity.

Hi there,

I`m trying to provisioning lab for this course in rol.redhat.com but it fails with this error: 

<code>traceback: "Traceback (most recent call last):↵ File "./role/api.py", line 154, in dispatch↵ result = super(BaseAPIView, self).dispatch(*args, **kwargs)↵ File "/opt/venv/lib/python2.7/site-packages/django/views/generic/base.py", line 89, in dispatch↵ return handler(request, *args, **kwargs)↵ File "./role/rhviews.py", line 928, in post↵ res = LabAPI.post(req, _data=self.input_data, **kwargs)↵ File "./sapi/labs.py", line 260, in post↵ return cls._package_result(return_record)↵ File "./sapi/labs.py", line 202, in _package_result↵ return_record['vm_summary'] = app.vm_summary↵AttributeError: 'dict' object has no attribute 'vm_summary'↵" </code>

Can anyone help me?

Thanks in advance.

Hi Diego,

The fatest way to solve issues to solve issues with virtual labs is to contact the dedicated support team. Enter access.redhat.com log in with your account (no need to log in again if you are already logged in to rol.redhat.com) and click "Open a Support Case".

Nice! There's still some bugs in the platform. e.g.: The progressive bar which tells you where you "are" within the content is not working anymore. It only worked the first session. It's a little bit annoying because everytime I start a session I've to start in the last recorded progress (14%) and now I'd be around 20%...
