Keep Kubernetes Current.
Without the Risk,
Toil, or Downtime.
KubeLift by OpsTree automates the full EKS upgrade lifecycle — from intelligent pre-flight checks to add-on reconciliation — so your platform team stops deferring upgrades and starts running the latest, most secure Kubernetes versions with confidence.
EKS upgrades aren't technically hard.
They're operationally expensive.
Most platform teams know they're running on outdated Kubernetes versions. The patch notes are bookmarked. The Jira ticket exists. But it never quite makes it to the top of the sprint. Here's why.
Compatibility and Dependency Nightmares
CRDs, Helm chart API versions, deprecated endpoints, and add-on compatibility all need validation before a single control plane node moves. Miss one, and you're debugging at 2 AM.
Manual pre-checks take daysDowntime Is a Real Risk
One misconfigured PodDisruptionBudget, one workload without proper disruption tolerances — and live services go down. Without a tested rollout strategy, the risk of disruption keeps upgrades permanently on hold.
No reliable rollback pathDevOps Teams Are Already at Capacity
Validate, prep staging, test, coordinate, schedule, execute, monitor — then repeat for every cluster and environment. For most teams, that's weeks of work per upgrade cycle competing directly with the roadmap.
Weeks of work per upgrade cycleNo Reliable Automation or Rollback
Ad hoc upgrade scripts don't handle partial failures, don't manage add-ons, and have no rollback logic. When something goes wrong mid-upgrade — and it eventually does — manual recovery under pressure is exactly where outages happen.
Brittle scripts, no rollbackRunning outdated EKS isn't just technical debt.
It's a security and compliance risk.
The longer you wait, the more expensive and risky the eventual upgrade becomes.
AWS End-of-Support Timelines Are Real
AWS supports each Kubernetes version on EKS for approximately 14 months. After that, clusters on unsupported versions stop receiving security patches and may face forced upgrades. Teams that defer don't avoid the risk — they accumulate it.
CVE Exposure Grows With Every Skipped Version
Outdated Kubernetes versions carry known, publicly documented vulnerabilities — many actively exploited. Staying current is the simplest way to reduce your cluster attack surface. Auditors and security teams increasingly flag version currency during reviews.
Skipping Versions Means Larger, Riskier Jumps
You can't skip minor versions in EKS. Miss two cycles and you're running a three-hop upgrade path — each requiring its own pre-checks, add-on updates, and validation. The longer you wait, the harder the eventual upgrade becomes.
Not a script. Not a runbook.
A complete EKS upgrade system.
KubeLift handles the full upgrade lifecycle in three integrated phases — each one automated, validated, and production-safe.
When all three phases run together, this is the measurable result on upgrade timelines.
Every phase of the EKS upgrade lifecycle.
Automated and validated.
AI-Assisted Pre-Flight Checks
Before any change is made, KubeLift analyzes your cluster against a comprehensive check matrix. Findings are risk-scored and surfaced with specific remediation guidance. Unsafe upgrades are blocked — you don't proceed on a hunch.
- Deprecated API usage detection across all workloads
- Add-on compatibility matrix against target version
- Node readiness and health validation
- PodDisruptionBudget and workload disruption review
- Upgrade risk scoring with actionable findings
Full-Stack Upgrade Automation
KubeLift orchestrates the complete upgrade sequence — control plane first, then node groups — using a safe cordon-drain-terminate-replace workflow. If something goes wrong mid-upgrade, built-in rollback logic responds without requiring manual intervention.
- EKS control plane upgrade with AWS API orchestration
- Node group rolling replacement with workload safety
- Multi-cluster and multi-environment sequencing
- Automatic rollback on health check failure
- Configurable upgrade windows and concurrency
Add-On Reconciliation
A completed control plane upgrade is not a completed cluster upgrade. KubeLift automatically updates all critical add-ons post-upgrade, validates their health, and flags anything that requires attention — before marking the upgrade complete.
- CoreDNS, kube-proxy, and VPC CNI auto-updated
- AWS Load Balancer Controller compatibility resolved
- EBS and EFS CSI driver version alignment
- Post-update health validation per add-on
- Blocked completion until all add-ons confirmed healthy
Real-Time Alerts & Audit Trail
Every action KubeLift takes is communicated in real time via Slack or email. Every upgrade produces a full audit trail — what ran, what passed, what was flagged, and what decisions were made. Useful for postmortems, compliance documentation, and team visibility.
- Step-by-step Slack / email notifications
- Pre-check results and risk scoring report
- Upgrade completion summary per cluster
- Failure and rollback event alerts
- Full structured audit log per upgrade run
The same cluster upgrade.
Two very different experiences.
A production EKS upgrade. Without KubeLift, and with it.
Without KubeLift
Manual pre-checks begin. Deprecated API review, add-on version research, and PDB audits spread across multiple engineers and tools.
Staging environment prep and test execution. Coordination with application teams to identify workload impact and schedule downtime.
Maintenance window scheduled. Upgrade script executed manually. Node groups drained one by one. Add-ons updated by hand.
Post-upgrade issues found — one add-on incompatibility, one PDB misconfiguration. Debugging and manual remediation underway.
With KubeLift
Pre-flight checks run automatically. Deprecated APIs, add-on compatibility, PDB issues — all surfaced with risk scores and remediation steps.
Two flagged issues remediated from the pre-check report. Upgrade approved and queued. No staging environment required.
Control plane upgraded. Node groups rolling — cordon, drain, terminate, replace — with real-time Slack notifications at each step.
Add-ons reconciled and validated. Upgrade audit report generated. Cluster confirmed healthy on new version. Done.
Manual upgrades vs. KubeLift.
Every dimension that matters.
KubeLift isn't a wrapper around kubectl. It's a purpose-built system designed for production EKS at enterprise scale.
| Dimension | With KubeLift | Without Automation |
|---|---|---|
| Pre-checks | Automated, comprehensive, risk-scored | Manual, partial, inconsistent across teams |
| Upgrade execution | Fully orchestrated cordon-drain-replace | Manual, script-driven, error-prone |
| Rollback | Automatic on failure — no manual intervention | Manual recovery under pressure |
| Add-on management | Auto-updated and health-validated post-upgrade | Missed or deferred — common source of issues |
| Visibility | Real-time Slack/email + full audit trail | Terminal output — no traceability |
| Time to upgrade | Hours — orchestrated, production-safe | Weeks — staging, coordination, testing cycles |
| Upgrade coverage | End-to-end: pre-checks, control plane, nodes, add-ons | Partial — control plane only, add-ons manual |
| Multi-cluster | Supported — sequenced across environments | Repeated manual effort per cluster |
What KubeLift changes about how
EKS upgrades cost your organization.
Measurable impact across security, reliability, speed, and engineering productivity.
Continuous Security and Compliance Posture
Always stay on supported Kubernetes versions with current patches. Staying current is the baseline for most security frameworks — KubeLift makes it operationally achievable, not just aspirational.
Engineering Hours Redirected to Higher-Value Work
The time reclaimed from upgrade toil doesn't disappear — it gets reallocated. Teams that previously deferred upgrades now run them on schedule, without pulling engineers off roadmap work.
Questions platform engineers
actually ask about KubeLift.
Why do EKS upgrades get deferred so often?
The honest answer: they're operationally expensive. Pre-checks, coordination, testing, scheduling a maintenance window — it adds up. When the work is manual and error-prone, teams push it down the list. KubeLift removes the manual overhead, which removes the reason to defer.
How does KubeLift handle failures mid-upgrade?
KubeLift monitors each upgrade step and has automatic rollback logic built into the orchestration. If a node fails to drain cleanly or a health check fails post-replacement, the system responds without requiring manual intervention. Every failure event is logged and alerted.
What does the AI-assisted pre-check actually do?
Before any upgrade begins, KubeLift analyzes deprecated API usage, add-on compatibility, node readiness, PDB configuration, and workload health. It assigns a risk score based on findings and provides specific remediation guidance. High-risk upgrades are blocked until issues are resolved.
Does KubeLift work on existing clusters?
Yes. KubeLift requires no agent installation and works against your existing EKS clusters via standard AWS APIs and IAM roles. There's no requirement to modify your cluster configuration before using it.
How are add-ons handled after the upgrade?
After the control plane and node group upgrades complete, KubeLift automatically updates CoreDNS, kube-proxy, VPC CNI, and other managed add-ons to their compatible versions. It validates their health post-update before marking the upgrade complete.
Can KubeLift manage upgrades across multiple clusters?
Yes. KubeLift is designed for teams managing multiple clusters across dev, staging, and production. Upgrades can be sequenced across environments, and each cluster gets its own pre-check run, audit trail, and completion report.
Your EKS clusters are already behind.
