Discovery session presented during Red Hat Summit 2019 about creating self-service solutions using Ansible Tower and OpenShift to onboard developers into the platform during Red Hat Open Innovation Labs for VW in Germany

1. How Volkswagen used microservices
and automation to develop self-
service solutions
Marcos Entenza
Principal Consultant - SRE @ Red Hat Open Innovation Labs
Youssef Chamseddine
Testing & Simulation Research and Development - Volkswagen

2. VW & LABS BACKGROUND
● DevOps for cars - test autonomous and parking pilot
capabilities
● CI/CD Pipelines for new car functions
● Prove the technology is able to accomplish existing needs
● Onboard different dev teams to work on the same goal
sharing same technologies and frameworks
● Move existing and new workloads to containers running in
OpenShift

3. DEV TEAMS & OPENSHIFT
● So, what is this container thing?
● Why do I need to maintain all those YAML and JSON files?
● I (Dev) just want to run my code and you (Ops) must ensure
is running all the time
● I (Dev) just want to run this container I build and you (Ops)
must ensure is running all the time
● How can I get my new code deployed in OpenShift?
● How can I get my new Dockerfile deployed in OpenShift?

4. BROKEN ECOSYSTEM
Hey, just got this
amazing Helm
Chart I want to
deploy to the
platform? BTW, I
want you to
maintain it once
deployed.
Hey, just got this
container from one
of our suppliers I
want to run! BTW,
how can I
customize it later?
Hey, I have the
code of this new
component on my
laptop. How can I
deploy it? BTW,
how can I send you
updates
afterwards?”
How are we supposed to
maintain all this chaos?
We care about the
platform, we do not care
about your code

5. Hey, I sent you
guys a new
container image,
when is this going
to be deployed?
Well, just created a
JIRA ticket with
some info there.
Need to get this
done ASAP!
BROKEN PLATFORM
Ok, where is it?
When do you want
to get this deployed
on how?

6. Hey, there is a new
feature we need to
test for this
component. Can
you please help?
Container image?
What’s that? I
though the platform
was doing that
automatically!? It’s
on my laptop and it
works.
BROKEN PLATFORM
Ok, where is the
code? Did you
already build a
container image
from that?

7. BREAK WALLS

8. CROSS-FUNCTIONAL TEAMS WITH...
● Shared common Framework
● Shared “language” on deployed objects
● EaC (Everything as Code) culture

9. CROSS-FUNCTIONAL TEAMS GAINING...
● Repeatable and transportable artifacts
● Scalability and ability to recreate across
different environments and Clusters

10. HOW WAS THIS SOLVED @ VW
● SHARED FRAMEWORK AND LANGUAGE - Self Service
approach with 4 core components
○ Ansible Tower
○ OpenShift & Template Objects
○ SCM (GitLab) - Everything is code
○ Jenkins - builds and deployments lifecycle, unit testing
and e2e testing
