Alerts are published 4 | via Slack webhooks to a configurable channel (using an annotation on the object or the object's namespace). 5 | 6 | ## Table of contents- [klint](#klint) 7 | - [klint](#klint) 8 | - [Table of contents- klint](#table-of-contents--klint) 9 | - [Rationale](#rationale) 10 | - [Building](#building) 11 | - [Using](#using) 12 | - [Rules](#rules) 13 | - [UnsuccessfulExitRule](#unsuccessfulexitrule) 14 | - [ResourceAnnotationRule](#resourceannotationrule) 15 | - [ScrapeNeedsPortsRule](#scrapeneedsportsrule) 16 | - [ValidIAMRoleRule](#validiamrolerule) 17 | - [RequireCronJobHistoryLimits](#requirecronjobhistorylimits) 18 | - [Building](#building-1) 19 | - [Notes](#notes) 20 | - [License](#license) 21 | 22 | 23 | ## Rationale 24 | We started Klint to help us move more production teams over to our Kubernetes infrastructure. It helps us achieve: 25 | 26 | 1. Identify and debug erroneous objects 27 | 2. Nudge objects in line with our policy as both change over time 28 | 29 | For example, we run another tool called [kiam](https://github.com/uswitch/kiam) to integrate with AWS' IAM roles, 30 | allocating each pod its own session-based credentials. On more than one occasion an application team had problems 31 | caused by their roles being spelled incorrectly. Although relatively easy to debug for the Cluster Operations team 32 | it is not a great experience for the application developer. Klint helps us encode such checks and proactively alert 33 | teams when they need to take action. 34 | 35 | ## Building 36 | To build the exectuable you can use the `go` tool directly: 37 | 38 | ``` 39 | $ go get github.com/uswitch/klint 40 | ``` 41 | 42 | ## Using 43 | 44 | 1. Run klint as a deployment with a single replica on your cluster. 45 | 2. Add an annotation to the namespace, or an object to be monitored: `com.uswitch.alert/slack: ` 46 | 47 | As objects change klint will compare them against the rules and post to Slack. 48 | 49 | ![Alert](alert.png) 50 | 51 | ## Rules 52 | 53 | ### UnsuccessfulExitRule 54 | When a Pod exits with a failure code an alert is generated. Additionally, recent log data is retrieved and output 55 | with the message. 56 | 57 | If Pods receive `SIGKILL` klint will warn that maybe the `SIGTERM` signal was ignored or that the graceful shutdown 58 | period is too short. 59 | 60 | ### ResourceAnnotationRule 61 | This ensures that Pods have cpu and memory requests and limits. 62 | 63 | ### ScrapeNeedsPortsRule 64 | If a Pod is marked as to be scraped via Prometheus (via the `prometheus.io.scrape` annotation) klint will ensure 65 | the Pod also specifies ports. We had instances where applications wanted to be scraped but without the port data 66 | it was unable to figure out what to scrape. 67 | 68 | ### ValidIAMRoleRule 69 | This rule checks for a valid IAM Role if users specify an IAM role (via the `iam.amazonaws.com/role` annotation). We 70 | had a handful of times where teams had roles with typos or that hadn't been created and it wasn't obvious why 71 | the Pod had no permissions to AWS. 72 | 73 | ### RequireCronJobHistoryLimits 74 | This currently enforces a relatively low limit insisting that CronJob objects must specify both success and 75 | failure history limits, and that these should both be lower than 10. 76 | 77 | 78 | ## Building 79 | 80 | ``` 81 | $ go build -o bin/klint . 82 | ``` 83 | 84 | ## Notes 85 | * *July 2024 -* The `klint` image is now stored in the `uswitch/klint` repository on Quay. 86 |
