About
kTailor is a lightweight Kubernetes mutating webhook that injects environment variables, sidecars, init containers, and volumes into Deployments using reusable YAML templates stored in ConfigMaps, leaving the original manifests untouched. It only targets labeled Deployments for near-zero latency and positions itself as a simpler alternative to full policy engines like Kyverno or OPA Gatekeeper.
What it can do
Inject environment variables into Kubernetes Deployments via mutating webhook
ConfigMap-stored YAML template and labeled Deployment → Modified Deployment with injected env vars
Inject sidecar containers into Kubernetes Deployments
ConfigMap-stored YAML template and labeled Deployment → Deployment with injected sidecar container
Inject init containers into Kubernetes Deployments
ConfigMap-stored YAML template and labeled Deployment → Deployment with injected init container
Inject volumes into Kubernetes Deployments
ConfigMap-stored YAML template and labeled Deployment → Deployment with injected volume
Target only labeled Deployments for mutation
Deployment label → Selective webhook mutation
Why it made the leaderboard
Platform teams can centrally inject monitoring sidecars, proxies, or env vars into Kubernetes Deployments without touching every team's manifests, cutting repetitive infrastructure boilerplate.
