Kakao is the 'mobile life platform' company dedicated to renewing daily lives and the leading player in the mobile messenger market in South Korea. As a member of the private Kubernetes as a Service team at Kakao Corp, we have seen an impressive expansion of the service which was 2K clusters with 20K nodes last year to be a 7K+ clusters with 100K+ nodes. With an unprecedented growing number of the clusters in our service, we have faced several problems never met before. One of them is an ever-growing number of on-call issues that are barely manageable with a DevOps team consisting of a small group of developers. In this session, we are going to reveal the secret of how the small team could successfully survive from endless issues generated from 7K+ Kubernetes clusters. We will also illustrate what tools we have made and why we opensource some of them.
