Some thoughts:
- Continuous System Integration Test (CSIT) per project, current level is low:
https://jenkins.onap.org/view/CSIT/ We should encourage project as part as
their milestones to have a certain level of coverage through CSIT. Maybe create
a reward, like the project that has the best test coverage (we’ve done this for
a few releases in ODL)
- REST API layer
- E2E functionality within the project itself (using simulators, …)
- CSIT for overall ONAP, e.g run close-loop use cases
- A better way to customize ONAP deployment in OOM. Currently everything is
coming from an onap-parameters.yaml file, which was done initially but isn’t a
good solution. Team is currently working on moving the configuration under each
helm chart (per project), so configuration can be derived from the helm chart
itself. Once done, we can create a common helm chart that will centralize the
ONAP parameters to be passed to any projects helm chart, it will basically sit
on top of the other, as illustrated bellow:
———————
common chart
———————
projects chart
———————
That way, projects chart can be configured to retrieved the value from the
common chart, or to use their own values (using Go Templating, e.g. {{
Values.common.appcversion | default v1.1.1 }} ). So basically we keep the
ability to deploy one chart at the time.
Finally, Helm provides the ability to overwrite the values.yaml properties when
deploying a chart, hence the common values.yaml file can be overwritten to
provide specific environment details.
- Create a CI process for OOM in ONAP’s Jenkins. As OOM is using helm chart for
each application, OOM should produce helm chart, and at release time, should
release helm chart, so consumer (GOCD, Cloudify, …) can consume them. This
currently doesn’t exist in ONAP, moreover, we need ONAP to be able to host helm
chart. Nexus doesn’t offer this capability yet. I know Bintray does, and it’s
on the way for Artifcatory. But we need support from the LF on this to find the
appropriate solution. Note, it could also be a simple HTTP server on which we
can have two folders, snapshot and release, and manipulate helm chart from
there.
- Create a CD process for OOM in ONAP’s Jenkins: Today we have Michael’s script
that does the job. But we should have something that provides more auditing,
better logging, better traceability, etc.... Internally we’ve been using GOCD
for that, and we’re currently looking at how to properly upstream what we’ve
done. GOCD allows to create pipeline, similar to Jenkins pipeline, but geared
mainly for CD and not CI. This will give the ability to deploy ONAP on
multiple/different environments. Also, this could be triggered by an upstream
Jenkins Job, like a merge job, or a keyword comment on a gerrit patch. An
alternative to GOCD, being currently developed in OOM, is Cloudify. So both
options will sit on top of OOM, consuming helm chart build by OOM.
- Ability to upgrade a component. Today, OOM only offers the ability to create
or delete component, which is underusing the advantage of Kubernetes that
support upgrade for any deployment.
With the upgradability feature provided by OOM, we will be able to re-deploy
only components that have changed, based on docker image version. So no need to
re-deploy the whole ONAP. And the best part is, it will rollback is the upgrade
has failed. So we can keep and “stable” like kind of environment where to
periodically run the CSIT covering the close-loop use cases.
Regarding how the process should work in Gerrit:
- I tend to think we shouldn’t have to wait for an hour or so to have a
Verified +1 from Jenkins, this is too long, and this will impact development
cycles badly. Ideally, the Jenkins verified job shouldn’t take more than 30 mn
if we want to be efficient.
The addition of a Gerrit trigger keyword to run it the full CSIT close-loops
suites will allow committer/developers to run more in-depth verification on
patches that they feel requires it.
