Upgrade Copilot for Open Source

Built for Kubernetes, Add-ons, Application Services and 100s of Open Source Software Projects.

Automate every phase of your upgrade cycle — from parsing release notes and diffing Helm charts to mapping CRD, dependency, and config changes. Our agent flags breaking changes, EOL risks, and critical defects early and identifies incompatible components and API deprecations. Provides pre‑/in‑/post‑flight validation checks, delivers ready‑to‑apply IaC automation code, and much more ...

Chkk dashboard highlighting the eks-prod-1 cluster

Instant visibility into what will break

Auto-maps every add-on, OSS project, CRD, custom resource, node group, and application
Flags API removals, operating-system impacts, and multi-hop constraints up front
Surfaces context-specific breaking changes—no generic runbooks; provides contextualized upgrade advisories

Focused view of Chkk's Upgrade Copilot, focused on the Add-On Changes step of Pre-work.

Version recommendations you can trust

Provides EOL dates, production maturity, and compatibility windows for hundreds of OSS projects
Suggests the safest target version, explains why, and links to upstream notes
Differentiates required, recommended, and optional upgrades

Application-client dependency guardrails

Detects misconfigured PDBs and deprecated APIs
Integrates natively with EKS, GKE, and AKS
Highlights the impact of changing add-ons on application clients; prevents hidden app incompatibilities before code reaches staging

Worker-node, OS, IAM, and cloud-policy changes

Assesses the impact of AMI/image, kernel, containerd, and cgroup changes
Warns when cgroup v1→v2 or syscall shifts break CNIs or service meshes; recommends patched images
Compares existing IAM roles against new add-on policy requirements (e.g., catches missing permissions for Karpenter, ALB controller, etc.)

Add-On & Multi-Hop Paths

Pre-flight, in-flight, and post-flight checks

Automated health and readiness tests per add-on version
Results feed directly into Copilot’s workflow tracker
Safety, health, and readiness checks for each add-on/OSS-project version

Helm values, template, CRD, and RBAC diffs

Generates side-by-side values.yaml, template, and overlay changes; supports Helm, Kustomize, plain YAML, and Argo CD application sets; guarantees every field and annotation is captured—no silent drift
Compares CRD schemas across versions—highlights breaking fields; produces patch diffs for every live CR instance needing migration
Audits ClusterRoles/RoleBindings against upcoming API groups

Live workflow, collaboration, and audit trail

Stages and steps auto-generated; teams add custom tasks or notes
Assign owners, set due dates, comment, and mark complete/skip inline
Full history retained for compliance, retrospectives, and auditors; generates diff-based PRs for Terraform, Pulumi, or Helm repos
