Kubernetes resource patching tool for Terraform
Built for DevOps/Platform engineers managing EKS clusters who need to inject configuration (proxies, env vars) into pre-configured system daemonsets without overwriting existing values.

“### Terraform Version Terraform v0.12.18 ### Affected Resource(s) n/a (request for new resource) In AWS EKS, clusters come "pre-configured" with several things running in the `kube-system` namespace. We need to patch those pre-configured things, while retaining any "upstream" changes which happen to be made. (for example: set HTTP_PROXY variables) kubectl provides the `patch` keyword to handle this use-c…”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
DevOps and platform engineers managing EKS clusters need to inject configuration into system daemonsets without losing existing values. Demand signal is unclear due to lack of search volume, but the pain is specific to AWS EKS operators, suggesting a narrow but defined audience.
Competition & the opening
Terraform AWS provider and Helm-based config management exist, but leave a gap around non-destructive patching of pre-configured daemonsets in kube-system without overwriting or requiring manual reconciliation.
What's hard to build
Requires deep Kubernetes resource semantics (merge strategies, ownership chains, daemonset update mechanics) and reliable state tracking across Terraform runs to avoid clobbering existing configurations. Testing against real EKS clusters adds infrastructure cost.
Why now
EKS pre-configured resources break Terraform state idempotency; JSONPatch is W3C standard but Terraform doesn't use it for K8s resources.
