Lessons learnt while operating multi-tenant kubernetes cluster in production - Prateek Nayak (MYOB)

At MYOB, as part of the Platform Enablement group we operate a multi-tenant kubernetes cluster in production. Our cluster come with sane, sensible defaults around monitoring, logging alert built out of the box for delivery teams meaning our devs can focus on delivering customer value. We have learnt quite a few lessons on our kubernetes journey mainly through investigation and sometimes through production incidents. We have also crafted some interesting patterns around using RBAC, Namespaces, Network Policies and Quotas to create the perfect isolation / separation for our delivery teams where they can co-exist on the same cluster without impacting each other. I would love share some of our learning and patterns with the wider community.
