Our platform team began with similar goals as other platform teams which is to unify and streamline deployments of all the teams under our organization. Then we got hit by a curve ball as life always does. We got acquired and this began the process of cloud migration. Cloud migration with K8s made things easier but there was more sinister problem lurking around. How do we create, destroy or retire clusters without disrupting teams?
This talk tells the story of how we replaced a patchwork of terragrunt based workflows with CAPI - Cluster API a kubernetes native framework for creating, updating or even deleting clusters at scale. You will hear the ups, downs and the cultural shifts that came with migrating infrastructure typically written in terraform to yamls.
