Find Kubernetes resources that have been deprecatedPluto is a utility to help users find deprecated Kubernetes apiVersions in their code repositories and their helm releases.
Documentation
Check out the documentation at docs.fairwinds.com
Purpose
Kubernetes sometimes deprecates apiVersions. Most notably, a large number of deprecations happened in the 1.16 release. This is fine, and it's a fairly easy thing to deal with. However, it can be difficult to find all the places where you might have used a version that will be deprecated in your next upgrade.
You might think, "I'll just ask the api-server to tell me!", but this is fraught with danger. If you ask the api-server to give you
deployments.v1.apps, and the deployment was deployed asdeployments.v1beta1.extensions, the api-server will quite happily convert the api version and return a manifest withapps/v1. This is fairly well outlined in the discussion in this issue.So, long story short, finding the places where you have deployed a deprecated apiVersion can be challenging. This is where
plutocomes in. You can use pluto to check a couple different places where you might have placed a deprecated version:- Infrastructure-as-Code repos: Pluto can check both static manifests and Helm charts for deprecated apiVersions
- Live Helm releases: Pluto can check both Helm 2 and Helm 3 releases running in your cluster for deprecated apiVersions
Kubernetes Deprecation Policy
You can read the full policy here
Long story short, apiVersions get deprecated, and then they eventually get removed entirely. Pluto differentiates between these two, and will tell you if a version is

Moresec Shangfu Cloud Native Protection Platform is a security protection model based on the concept of cloud native. In view of the characteristics of cloud native application life-cycle, it involves in many stages of security protection, including R&D construction, security testing, image control, container deployment, container operation, etc. Shangfu also integrates security with development which means providing feedback of the application security condition through correlating operation asset, and promoting the iteration and upgrade of application. Whereupon, a closed loop of efficient cloud native application security risk is created, covering the whole stages of DevSecOps.
