1 | # Kubesweeper
2 |
3 | Automatically iterates through resources in a lab Kubernetes cluster and acts according to [certain conditions outlined here](#configuration-defaults). As of now, Kubesweeper will delete ```Deployments``` and their associated resources if the waiting reason and/or pod restart count and/or deployment age dictates. Additionally, you can use configurable Boolean environment variables to choose to delete associated ```Services```, ```Ingresses```, and ```HorizontalPodAutoscalers```.
4 |
5 | If your lab Kubernetes clusters are filling up with non-Running pods, then Kubesweeper's automatic deletion
6 | can assist. Future iterations of this project can involve other actions based on crawling through Kubernetes cluster resources, such as generating reports per namespace without actually deleting.
7 |
8 | Please note that Kubesweeper is intended for use in lab—not production, customer-facing—clusters. Any automated cleanup in such an environment is unadvisable, at least for Kubesweeper.

45 | ## Deployment as a Kubernetes CronJob
46 | If the desired cluster does not have Knative installed, then Kubesweeper can be installed as a Kubernetes CronJob.
47 |
48 | 1. Build Docker image
49 | ```bash
50 | $ docker build -t kubesweeper .
51 | ```
52 | 2. Create Kubernetes resources from ```install``` directory
53 | ```bash
54 | $ kubectl apply -f install/
55 | ```
56 |
57 | Note that step 2 must be run in the context of the Kubernetes cluster. After that command is run, the appropriate Kubernetes resources will be created from the .yaml files in ```install```.
58 |
59 | ## Deployment as a Knative CronJobSource
60 | If you wish to deploy Kubesweeper on Knative as a CronJobSource, you can use Helm. For information on installing Helm, please refer to the [Helm quickstart guide](https://helm.sh/docs/using_helm/). After installing Helm, the following steps can be manually run:
61 |
62 | 1. Build Docker image
63 | ```bash
64 | $ docker build -t kubesweeper .
65 | ```
66 | 2. Run Helm template to install Kubesweeper
67 | ```bash
68 | $ helm template kubesweeper --set image= | kubectl create -f -
69 | ```
70 |
71 | In lieu of step 2, a Makefile can be used to pull values from ```~/install/helm/kubesweeper/values.yaml```:
72 |
73 | ```bash
74 | $ make
75 | ```
76 |
77 | ## Configuration Defaults
78 |
79 | Under the ```configs``` folder, the ```config.yaml``` has the following default configurations:
80 |
81 | * Pod waiting reasons
82 | * CrashLoopBackOff
83 | * ImagePullBackOff
84 | * ErrImagePull
85 | * Completed
86 | * Failed
87 | * Pod restart threshold *(in other words, if pod restarts exceed this number, then delete)*
88 | * 100
89 | * If the pod restart threshold is at least this number *and* has a pod waiting reason of ```CrashLoopBackOff```, then Kubesweeper will delete the associated resources
90 | * Deployment age threshold *(in other words, if the deployment creation date is before this number of days, then delete)*
91 | * 90
92 |
93 | You are able to configure these values to your choosing.
94 |
95 | Helm function configurations can be found in ```~/install/helm/kubesweeper/values.yaml```.
96 |
97 | * name
98 | * Name to use for deployment
99 | * image
100 | * Image used in deployment
101 | * cron
102 | * Cron expression used to schedule Kubesweeper
103 | * Any valid cron expression can be used
104 | * namespace
105 | * Namespace job will be deployed in
106 |
