On May-21, Amar Kapadia & I conducted a webinar on the topic of “Debugging OOM Failures”.
We started off by giving some context. Our objective was to develop a lightweight, repeatable lab environment for ONAP training on Google Cloud. We also plan to offer this image to developers that need a sandbox environment. To accomplish this, we used ONAP Amsterdam along with OPNFV Euphrates. ONAP was installed using OOM that uses Kubernetes and Helm. All of this software was installed on one VM on the Google cloud.
For most users, issues that pop up once in a while are OK. However, for us, the deployment process needed to be consistent and repeatable. For this reason, we had to debug every intermittent failure and develop a single-click workaround script.
The webinar next talked about the 7 issues we faced, how we debugged them and what the workarounds were. The issues faced were as follows. Other than failure#7, the other failures were all intermittent:
